not exactly...... i went and tested a 10 w7 and a 9510 both in ported applications both off jl 500.1 and to my ear they sound extremely close however that extra thump that I WILL REQUIRE from either 10 comes from the mtx more than the jl, thus i fell like the mtx sub b/w the two tens is ideal ...... period.
mtx9510>jl10w7
(i just paid for the ten, it'll be here in a few days)!
remind me to take a picture of that 10 next to the 13 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
