The Heisenberg SQ Build

[CoLd_FuSiOn]

Had a chance to listen to this setup. Downright awesome. One of the best cars I have heard in a long time. The RCAs, Amp, HU and speakers are all top notch performers. A true 4 way active system, and tuned very well. Hats off.

Never thought a D class can sound so good in an SQ system. Way beyond its competitors. A very well thought out buy Coldie. The Dyn setup has truly come out of the closet with this clean power and the awesome door damping. Spot on performance.

Well done Coldie. Was absolutely a pleasure listening to the new setup. The bar has been set.

If you want to know what is a pure 4-way active SQ setup and how it should sound, listen to this car.

Really humbled by those words of yours Omar bhai,thank you so much!

Always a pleasure to share passion with fellow enthusiasts like yourself,God bless.

Alright then. Hello people. Never been much of a poster at this forum, but have been around long enough to observe and grab the priceless knowledge all gurus and other members have shared here. So coldie is basically the first pakwheeler I got acquainted with. Since then, this 'wakfiyat' has transformed into a strong bond of friendship. Now celebrating 2+ years of successful fraaandship.

Been there from the time he started with his set of forgot the brand components, followed by Focal, Morel and finally Dyns. So here is my review of his current rig. I visited Ahmed after he got his hands on the latest Arc goodie. After carefully studying the receipt for his new purchase no pun intended, I was curious to see what improvement could this D-class amp bring to his setup (I will get to that later).

The guy runs high-end equipment as we all know. We also know that it's never only the calibre of the stuff that matters, but also the level and quality of install and tuning. He threw in a little dose of Deadmau5 to show me how it played. And believe me, the Deadmau5 played exceptionally well. Being a listener, who enjoys and appreciates quality playback of vocals, we moved on to some vocally rich tracks. It sounded as if I was listening to a live performance, with the vocalist centred right in front of my eyes. The Dyns have this ability to reproduce music as neutrally (my opinion) as possible. It was a treat for the ears, with 0 or unnoticeable ear fatigue. Even at really high volumes, there was not a single moment where I wanted to ask him to turn down the volume.

The staging is brilliant, and the focus is dead-centred. The music bounces off from one point of the dash to the other seamlessly. The instruments played in the track come to life. A drum snare for instance has the same impact it would have when played live in front of you. The stage height feels eye-leveled. The depth is mesmerising. It came as a surprise to me since I had my doubts whether drivers in kick-panels could produce such staging results. Much effort was put in installing 8" midbass drivers, and trust me, the results generated are more than satisfying. The midbass drivers integrate so well with the sub as to produce transparency when it comes to lows and mids. The midbass is punchy enough to satisfy an SQL lover, accurate and controlled enough to put a smile on an SQ lover.

For the mighty w15gti, all I have to say is that hands down, it is the best sub I have ever listened to so far. It may seem like an overkill when used in an SQ application, but to those who see it that way, I highly recommend you to give it a listen. It works wonders in coldie's setup. It is a stealthy killer. It is hard to detect its location, yet it blends in so well that you need to mute the lows from the DSP to realise what role it has been playing. Apart from that, it is a really quick sub. It kicks in and then fades away very responsively. It was also a discrete tool to satisfy my not-very-dominant SPL bone, once it was levelled up a bit. I really wonder what this sub would do once fed at least its nominal power rating. Im pretty darn sure it will come off as a surprise even to some SPL listeners.

As far as my knowledge and experience is concerned, I used to believe that D-class amps, although efficient powerhouses, were always dynamically inferior to A-class and AB-class amps. I was proven wrong with this latest goodie. The ArcAudio 1200.6 is a masterpiece. An all in one solution to power hungry speakers. Whether it's the amp, or the component speaker set, or the beautiful combo of both, my ears could not spot any missing detail in playbacks. Moreover, it sounded so controlled and clean. Even upto 90% volume, there was no distortion in sound.

All in all, Ahmed's current system is definitely a giant, tailored to account for details when it comes to SQ. I highly recommend people to seek a demo, to better understand what I'm trying to convey, and to see what a finely tuned system sounds like. The install speaks for itself, and tells the tale of an enthusiast with a keen eye for detail. The guy knows his hardware, and also knows how to make the most of it. Thumbs up from my side. Enjoy.

PS. The review is based on my personal opinion, and still being new to this field, the review may lack the 'technical terms' used in audio systems.

Demo this setup some days before ....

[U]Amp:-

[/U]The Gustaa part is its even hard to believe the amp is 6 channel ... That too with class D circuitry makes it more tempting !
Extreme tiny ,One amp for activate the active scene of 3 way comps !

[U]Performance:-

[/U]No match of performance with its size ,Absolutely Worth spending ...

Last time auditioned the same setup on MAC clones amp ,but this time there is a big difference I felt ... There is a great depth and wideness felt in the staging ... The image is perfectly settled to center !

Amp tone feels warm to ears ... Blending with the nature of Dyn's !
Backgrounds musics and instruments felt sharp and its feels takes the whole listening pleasure to next level !

Crux:-

Its worthy purchase at the end of the day ... 2 (Y)

[madhouse12]

so here comes the part two of the demo i had in rawalpindi.

this part is, as i mentioned in my post earlier, of the change there is from his old setup to his shift to arc audio amps. and what a change it is. pick a guitar and strum a few notes on it and listen to same notes on coldie's system and u wont believe how true to life they are. the midbass the midrange the tweeter and the sub all blend in so smoothly and effortlessly that the actual drivers just disappear and all you hear is pure bliss.

the eq and TA are just awesome. very nicely done bro.

Wow, thanks for the extensive review my friend I'm completely at a loss for words.It's been a pleasure my friend and you're one of the few people who have seen the whole journey and how much input has gone into it to get to this stage.

Thank you so much, really means a lot.

Thank you so much talha, it definitely has been a revelation.

so here comes the part two of the demo i had in rawalpindi.

Thank you so much maddy bhai, I'm glad you liked it still in the learning phase and always a lot more to learn, I consider myself small to the knowledge that's out there.

Anyways, an unexpected turn of events and this has been a pleasant surprise to say the least.

After using the Harman Kardon CA1500M I always felt there was something lacking, the JBL w15GTI is a beast and is rated at 800 wrms @ 3 ohms. The Harman, although a great amplifier just wasn't cut out for it and therefore something more powerful was needed.

As they say, when there's a will there's a way. Couldn't find one of these bad boys locally so had to bite the bullet and take the plunge. So without further a due, a bad boy to power up another bad boy from the same heritage of audio fidelity that has gone into the development of the GTI Subwoofers, enter GTO.

Efficient bass power always set correctly
JBL's compact GTO-1001EZ amplifier will drive your subs with up to 1,000 watts RMS, bringing exciting, visceral impact to the music in your car. This mono amp looks very cool with its "old-school" styling, and JBL includes a few innovations that really separate this amp from the others.
Simple Setup System for setting amp gain
One of the biggest problems with installing an amplifier is setting the gain properly. JBL has come up with a fool-proof method for getting it right, ensuring full-power performance and distortion-free play. Using test tones on the included setup CD, you adjust the gain knob until the yellow light or the red light goes off, and the green "Gain OK" light comes on ? it's that simple. You'll never have to worry again about your amp "clipping" the signal, and possibly damaging your speakers or subs.
Plays well with factory radios
This GTO amp comes with screw-on bare wire-to-RCA adapters that let you hook up the amp, using your car's factory speaker wiring to supply the input signal. In some vehicles, the factory radio shuts down when you try to tap into the speaker wires, displaying a "no speakers are present" message. This amp features a special circuit that fools those factory radios by simulating a speaker load. The onboard crossovers and bass boost let you fine tune the system to perfection, and the large recessed knobs mean you don't need a tiny screwdriver to make your adjustments.

Product Highlights:

• mono subwoofer amplifier
• 650 watts RMS x 1 at 4 ohms (1,000 watts RMS x 1 at 2 ohms)
• CEA-2006 compliant
• frequency response: 10-280 Hz
• Class D amp technology
• variable low-pass filter (40-280 Hz, 12 dB/octave)
• variable bass boost (0-12 dB at 45 Hz)
• Simple Setup System with test tone CD for perfect gain setting
• optional wired remote level controller available soon
• preamp and speaker-level inputs (speaker wire-to-RCA adapters included)
• switchable automatic signal-sensing turns on amp without need for remote lead
• fuse rating: 40A x 3
• 6- or 4-gauge power and ground leads recommended ? wiring and hardware not included with amplifier
• 14-11/16"W x 2-5/8"H x 9-11/16"D

And hey, no need to get upset. Here are the pictures so take it EZ

Review: The bass has gotten even more transparent and the subwoofer sounds nothing like it used to anymore, it's like the shackles have been removed from the hungry beast and it will hold no prisoners now. I've had to lower down my levels just to match it with the fronts by around 10 decibels! What it does is with precision and authority and boy oh boy even the SPL guys have got to take a listen to this.Turn up the levels and you've got yourself some chest thumping ,rear view mirror bumping clean bass that's never ever out of control.

Moral of the story: A great addition to the empire of the sun

This Saturday night I had the pleasure of having a demo of "The Heisenberg SQ build" .. It was the most eargasmic experience I've ever had. The demo covered a wide genres of music from modern electronic music of "Infected Mushroom" (Cold Fusion's fav) to classic rock with Freddy Mercury's amazing vocals coming to life.

Being a music enthusiast I could hear each and every detail coming from the instruments be it the slight buzz from the acoustic guitar, the harmonic notes the drum sticks striking the snares and the cymbals. My fav part of the demo was bohemian rhapsody. Having heard this song a billion times and having memorized its isolated vocal and A Capella tracks note by note, the reproduction by this setup were simply incredible, accurate and precise.

Coming to the newly added sub section. Cold Fusion played a song and asked me to hold on tight .. Now when that part came .. What I experienced was a BASS BOMB being fired going up in the air traveling through the car and exploding over me !! That bass bomb would put any SPL system to shame

In short the setup shows the amount of hard work put into it !! Amazing

[omarss]

Heard Coldies setup before the Amp update, hands down is one of the best setups I have listened to till now.

Is the closest sounding thing to a home audio one can get in a car.

Calls for another demo to experience the new bad boy. WTG Coldie.

So been lazy to post a couple of updates i did a few months ago, so let's just get it over with.

Although initially the IMM-6 by Dayton audio was not bad for frequency response measurement. I always felt the need for something which was more accurate and would also allow for measurements in the phase and time domain as well.So got this a couple of months ago and it definitely brought the setup to a whole new level.

Cross Spectrum Labs Calibrated-Mini DSP UMIK-1

https://www.minidsp.com/products/acoustic-measurement/umik-1

It's basically a plug and play microphone that does not require a phantom power source and can be used with most applications out there whether they're PC or MAC based.

More details about Cross Spectrum Labs and calibration in the next post...

Pictures:

[CoLd_FuSiOn]

Looks like one of those things in star wars...

So let's see how it does with my reference studio monitors.

Let's get this party started

All boosters are set to fire sir...

The measurements

Listening impressions: Huge difference in imaging and overall smoothness.

Now usually people order the UMIK-1 from their website. The problem with that is that the microphone comes with a on-axis calibration file and as we know car speakers aren't listened to on-axis hence to tackle this problem the microphone was calibrated by a sound engineer with a certified reference microphone, this does not only ensure extremely accurate calibration but the necessary 45 degree and 90 degree calibration files as microphones usually exhibit a roll off after 6khz as they get more and more directional. More light or should i say sunlight has been shed on this on home theater shack forums and this is exactly why i didn't go with a normal UMIK-1.

Similar to the Dayton Dayton UMM-6 microphone, MiniDSP UMIK-1 microphones have a USB output so they can be used with PC's and Mac's without need of an external phantom power or USB/Firewire interface. The UMIK-1 appears as an audio input device available for use in many audio measurement software programs. The stock units come with on-axis calibration curves.

We provide the following value-added services:

We provide calibration files (.FRD format) on a USB thumbdrive for use in many popular audio measurement programs. Our cal files range from 5 Hz to 25 kHz to encompass the low bass and high treble regions that many audiophiles, professionals and home theater aficionados require.

Our measurement methodology compares favorably with the results generated by a NVLAP NIST-traceable laboratory so you can be confident that your data are reliable and are representative of the UMIK-1's individual performance.
As with our other calibrated microphone products, each UMIK-1 microphone is calibrated against an ANSI-certified reference microphone. Each microphone will be shipped with the following:

MiniDSP UMIK-1 microphone with mini-tripod, case, USB cable, and microphone clip
Microphone characterization report
Frequency response curves at 0?, 45? and 90? angles of incidence
USB thumbdrive with frequency response data (.FRD format)

Value addition indeed! , an instrument is only useful when what it measures is precise. Accuracy without precision is nothing.

Thanks to G.Holey for calibrating my microphone [emoji14]

Here's the final tune as seen on august 13th 2015, everything in phase with filters applied on room EQ wizard which is extremely popular for tuning purposes within the home and car domain.

Time alignment check, acoustical phase check, acoustical slopes check, filters check, sunshine check. [emoji14]

Good going Ahmed, great going, but i wonder why did you post this so late, you have this since quite a while now.

Please don't hold back the rest of the equipment which you have. Post it already, or you want to stir and spice up the fun more?

[omarss]

Good going coldie, this mic really made the setup shine. The old setup sounded a 100% new and improved with the mic tuning. Amazing results.

Now, with the new amps, wonder how it will sound.

BTW, I will need some eq tuning help also :D, will your mic be available?

Are you still running your home on the Marantz amp????
