For the money, the sub you reference looks pretty darn good. Some might not like the piano black finish, but I think it looks pretty cool. The one reservation is the cabinet. I'd call them and make sure it has sufficient bracing. The driver is very solid and very impressive, however I don't know much about the amp. I suspect it's something like the Apex Sr. which is a decent plate amp more than capable of driving the driver nicely. I think it would be a nice match for the Ref 1's, which are very good speakers.
The CSS site doesn't inspire confidence so, any suggestions or other input is appreciated.
??? What's this all about? The site isn't hard to navigate and CSS uses high quality drivers from Adire and other high quality manufacturers. I don't know what doesn't inspire confidence, however they seem to offer some good values.
Another sub that I'd think about is the Rava by Adire Audio. It's a very nice sub. Tight, fast bass and very musical. Not the last word in boom, but it should do well in your room. For the money, it's almost impossible to beat.
If you can glue together a cabinet, I have a suggestion. Check out:
Driver: SCC 300 from Soniccraft.com - $150
Amplifier: Apex Sr. from Apexjr.com - on sale $135
Cabinet: 3 Cubic foot flat kit from Partsexpress.com - $129 shipped
Stuffing, glue and screws - Partsexpress $20?
Veneer - ? depends on how fancy you want to get, but let's say $50
Total: approximately $550-600That would be my suggestion.
Good luck and congratulations on your purchase.
