stratusrt01 Posted November 26, 2006 Report Share Posted November 26, 2006 There's no specs on the older XXX 18's now that US Amps took over, so I was wondering what size box would work best for daily driving on about 2000 watts for this sub. I was thinking 7 cubes tuned to around 34hz, but someone told me that he had his in 6 cubes. Will 6 cubes really work well, because I'm working with a tight space, and it's a lot easier to get 6 than 7, but I can do 7 if it'll be a huge difference in output, or is there a different size I should be looking at. This is my first build for a big woofer, I'm used to doing a few small woofers instead. And how much power do you think that XXX will hold daily with a fresh recone?

audiobass10 Posted November 27, 2006 Report Share Posted November 27, 2006 6.5 cuft tuned to 33 with 1500rms I agree^^ That was almost the exact box I had for my 18SX...mine was 6.5^3ft tuned to 32hz with four 4" aero ports..I'd suggest the same to you...something similar to this..

stratusrt01 Posted November 28, 2006 Author Report Share Posted November 28, 2006 I was actually going to use 2 6" aero's for this one. This is going to be a fun build. Lots of cutting, building in the car and fiberglass. 6.5 to 33hz it is....Now I've just gotta fit it in there. Link to comment Share on other sites More sharing options...
