Stereo Integrity HT 18's are now going to for 160 shipped. For the quality of the speaker, that's a very good value. 22mm xmax, very quiet suspension up until about 25mm or so, xmech at 32. Low inductance, uses shorting rings with a smallish coil, woofers can mechanically play up to 200hz without issues, so normal sub crossover is no sweat. For playing music and sounding good daily, these should be tits.
Anyways since they are a high bandwidth driver and have very soft suspensions, I'm thinking about doing a sealed box for 4-6 of them, space permitting. That way I won't have to deal with port resonance or any other nasties that limit bandwidth, simplier build as well, it'd be my first wall. 4 of them will be good for nearly 130db just in the lower midbass region, no cabin gain, it'll keep up with my high quality pro audio frontstages I love so much
If I give each driver 3.5-4 cubes I can power them all off a Ampere Audio 3800.1 that I just got. I'll have paid total between 1200-1700 for the subs AND amp lol, that's great for everything being new, I think..
Probably a B pillar wall, havent decided yet. Has anyone ever sat in a large sealed build before, maybe JP's van, or anythign similar? Just looking for subjective impressions. I've actually never metered any of my cars, just not a goal of mine... I'm coming off of a ported 21 on 2k in the cargo area, so this shoudl be a good upgrade due to cone area alone, even if I do 4 due to more cone area AND much smaller cabin. It'll be minimum of 3x the cone area give or take a bit, losing the ports displacement, but these woofers have more xmax down low.
Edit: Before anyone say's "move this to the SPL forum" this thing is purely for daily driving and listening to music. Yes, I will blast Young Jeezy or Lil Wayne through it, yes, I will also then turn the subs down to listen to some eagles or Alice in Chains lol.
