I'm considering buying a Carver knightshadow for approx. $1050 CDN + tax. This comes out to around $655 American. I was wondering if there are any subs in this price range that can compare with the performance of the knightshadow. I haven't had a chance to demo any of the SVS subs, but I have heard so many great things about them and was wondering how they compare. Also, I was wondering if there are any SVS subs in the same price range as mentioned above. Thanks in advance for your input.
