I suggested my friend to buy the complete Sonodyne Package from Vipual Audio Tech as he had a tight budget. I had listened to his (Praveens) custom made speaker for a little while. They are good but i preferred Sonodyne products.
IMHO, speaker design needs good engineering (R & D) to sound the best.
Hi,i have seen vipul Audio Tech Custom made speakers.they are VFM,But i don't think that they can give 5.1 Home Theatre setup Speakers for 20k with Active Sub woofer.
