Looks great, how does it sound, and which driver and alignment did you use.

12" Dayton Titanic MKII
EBS design ~4.8L internal volume

powered by external PE250 amp

I think it is pretty good but it seems like it can't "handle" really big rumbles (i.e Monster's, Inc. sock explosion) Posted Image

Maybe I did the port wrong or something Posted Image

I have the amp level on halfway

I think it's just the movie. My Samson S1000 would always clip with my CS Ultra on the part when I was 10dB under reference.

So, which is it (amp or driver)? What is "clipping"? Sorry, I'm a newbie! :b

I'm just glad I got the subwoofer built (BTW thanks to anyone with picture guides this wouldn't be possible without the interesting links Posted Image)

Clipping is a form of amplifier distortion, it sounds really nasty with the Samson amps.

What's the tuning frequency?

Well...not sure Posted Image I used the full length... i suppose the WinISD calculated it to be around 19 Hz

btw here are some construction pics

Very nice sub!

Clipping is when an amplification circuit is driven past
it's dynamic headroom. When operating within it's limits
the output is a smooth sine wave but when an amp is driven
into clipping, the gentle radiused peaks of the sine wave
are "clipped" off turning the sine wave into a square wave
and well, speakers don't like to reproduce square waves.
Generaly with mids and woofers it's not an issue but with
tweeters it can fry them instantaniously!
