The NHT Classic 10 and 12 subs are reasonably priced and are quick enough to be used with music. I use them with NHT Classic 3s.
System
I'm trying to assemble a decent but not overly expensive system. I have Totem Rainmakers, and Triangle 202. Currently I use an inexpensive Yamaha sub. It has been suggested that I get a "fast" sub. I don't know what that means. My budget is limited to $200-400, new or used. My room is about 12x14 Any suggestions? Thanks in advance.
