I purchased an ma audio ma10sy sub not long ago! Guys for spl this lil woofer is insane! The biggest downfall was enclosure size. I checked ma's specs and it called for 3.0 cubes ported, then i ran it on my box program and got the same results! So i built that enclosure man did it hammer! I ran it on a small jbl amp and was shaking the crap out of the steel rafters in the old shop where i used to work! Then i picked up on a clacking sound and removed it to find the spider has seperated in one spot from the basket. Now i have to reglue it no big deal! Has anyone tried this woofer? I'll let you know the spl level in the stang as soon as i get some!
