Hello, I would like to buy a subwoofer that complements a pair of very fast speakers. I know very little about subs since I rarely used them, and I am wondering what are the models that are considered to be extremely fast and good, no matter at what price point. Thanks.
I second the Vandersteen 2Wq. If you have the funds, consider a pair of them, and consider an upgrade to the MHP-5 active crossovers. Fantastic subs that are tuneful, fast, and very easy to blend with your mains.
