I literally listened to it for 2 mins at a low volume. I'll run some sine waves through it when no one is home and see how she does, maybe add some EQ with the mini dsp. Then I'll throw in a blu ray and crank it up!

It just barely fits that location as if you designed it that way.

Wow
masterpiece...
how it sounds !!!

btw, why you choose an 18" driver if most of the times you will not need that SPL's
with a TH with an 8" or 10" you will have enough
im not an expert on subs design but have seen some pretty nice figures with TH boxes
with singles or duals 8" or 10"s

Thanks!

Well I had 2 12's but they weren't tuned low ebought for HT (which is what this system is strictly used for)

And once I saw this new Dayton driver I really wanted to try it out! For $250 plus two sheets of 18mm Baltic ($130ish) you can't beat this really. Well with some EQ as well to boost the low end roll off from a sealed box. But it's a great setup for the $. For any $ actually even twice that price!

the more i see this stuff the more i start to dig it
hopefully i will start to butch some wood soon

so, what was your mini DSP parameters
high pass freq (24/48 LR )
at what voltage you limit your box
and what amp you are using to drive it ( 8 or 4 ohms )

I think I set the high pass at 15hz? With a sealed enclosure its not *as* critical as a horn or BR where excursion increases rapidly. Excursion still rises in the lower octaves but not as rapidly.
I wanted the full 20Hz from this box...at low listening levels. If I was really abusing this, I'd be more careful with the high pass, set limiters in the DSP etc. but as Josh pointed out, this driver has plenty of xmech to play around with, even if Xmax is only 12mm or so.

The amp is pretty powerful, 1500rms at 4 ohms.... clean power? I'm guessing 1000-1200or so with low distortion.

ic, i wish the minidsp implement a limiter and tha would be the poor mans driverack

[m R g S r]

They do. They also have a balanced 2x4 board which would work well with pro audio stuff. Check it out!

cant find where the limiter settings are
