thats called making a profit :).
@poster and others.... remember you get what you pay for. knwood 718 has a million copies. original is not available. original discontinued back in 2004. all those made in vietnam and god know where are fakes. that speaker is only good for bass. it has no quality in mid or high range.
as for other speakers in 2k range... they only last 2-3 months at most. you will be back to the shops buying speakers again. so why not wait two months and get some good speakers in 4k range that will last you a long time.
i got my first speakers back in 2003-2004. i paid 6500 rs for them back then which was a big amount (100$, pioneer tsd690r). i sold those speakers last year and they were still playing beautifully. sold them at 3500Rs same day i posted em (my asking price) and in the evening i got a call from someone willing to pay me even more. so a good speaker not only lasts you a long time (7-8 years in my case) but also sells for a decent price. you take those 2k speakers back to the shopkeeper the next day and he will offer you 500 for them max IF he decided to buy em at all.
