why do people think that they will get better "Response" from vented/ported box tuned low? cause you wont. all you do is increase volume over a specific range while decreasing volume in the rest of the audible "spectrum"
sealed box = better response and cleaner bass.
it also means you dont ever have to worry(well not "ever" but mostly) about going beyone the limits of the box. In a vented box, if you play beyond the tuned range, you lose motor control, which yeilds the sloppy sound. its also known as "unloading"
you want louder bass, with the same woofers, and same power, build a vented box. Want cleaner sound, and a broader range, go sealed.
i like 15s. piss off. lol. i've never had a 12 in any stereo i've ever built. and i've never had a complain about the sound quality or volume (unless its' too loud). 10s or 15s. 12s are just the wuss middle of the road choice.
since i just read the last post, and the 12s are much cheaper, get those. lol
