@ poster, these active subwoofers are only good when you have serious space issue OR one does not know how to wire and install an amp + a sub. Avoid them.
Since you are in Lahore and availability in "Pakistan" of all the stuff is a serious issue, yahan log haath mai paisay lay kar ghoomtay hain to buy stuff ..... but they cant find the stuff they are after
Since you are after a nice setup for every day listening, dont choose subs like Pioneer 3002 these are pure spl stuff. these spl subs will degrade the sound quality of your setup and they will never blend with the rest of the components installed.
If talking about Lahore and bang for buck find yourself an Infinity Reference or a JBL GTO sub.... they stay clean and cover all the bass frequencies which your 6.5 components speakers cant.
If you want to get fairly loud or like your bass little on the high side... you need a SQL sub for that matter Cerwin Vega Vmax is your ultimate choice. I would have recommended you an Alpine Type R sub as well, but the premium over the cost price the sellers are asking for is sky high.
