downlow Posted March 25, 2009 Report Posted March 25, 2009 new hear, had my setup for awhile, want more out of it, currently is 2 12" hx2 powers in 4cu ft. ported box tuned to 32 hrtz. amp is a a2300hct, had it metered last year at 144.1 on music, ? is , is this box to small for these subs? would 5cu ft. be better?

lowblueranger Posted March 25, 2009 Report Posted March 25, 2009 I think the size is fine- is it braced and double 3/4" mdf? It might be tuned too low to get higher db levels? I'm not familiar with your amp. How many watts does it put out at 2 ohms, that is if they are dual 2 ohm subs correct?

downlow Posted April 1, 2009 Author Report Posted April 1, 2009 heres some pics. sry for the delay, wondering if anyone can calculate the actual cu ft of this box, plus what its tuned to, ty box size is 20"(d) x 35"(w) x 13"(h) and also the port goes in 11 inches. Quote

solo z Posted April 4, 2009 Report Posted April 4, 2009 Bump for some clean looking HX2's!! i had one but couldnt find a second so i had to let it go. those are some good speakers Quote
Sinosic Posted April 4, 2009 Report Posted April 4, 2009 if the ports are 1.25" wide x 11.5" tall x 11" long internal volume after port displacements your looking at 3.782 cuft @ 39.89hz. of the top of my head i would say 5 cuft @ 40hz with each port 2.5" wide will yeld more spl and still sound good on music.
