sorry i meant my mates kappa pro 10s are infact INFINITY car audio ones with 88db/2.83v speakers in tiny sealed boxes,obviously he wants high output,but hes really stretching them too far,350watt rms each and he killed his car battery the other day-with the motor running- :-P
even songs that i couldnt notice in FFT that had 30hz,i notice 'more' sound,im getting simply more complex waves,more sinewves that werent there ,which is always good :-D even if they are only 30-40hz
the sound is so nice,the bass actualy has a different character to my 8inch thumper,i like it :)
if i wanted to strengthen the box,could i put another 18mm sheet over the back face of the box,because thats an easy panel to add thickness to-id use HEAPS of glue and liquid nails perhaps,,
because i knew when i designed it the box would be a little to thin even with bracing inside.
could the small amp with its clipping,be making high excursion,pushing the speaker out of linear zone,make it go even further out of strong mag field ,so it goes alot further than if the signal was clean and nice..
thanks wayne
