Completed Sonosub (picture) (1 Viewer)

Well, I finally finished it!

I'm a newbie to DIY and everything.. but it turned out pretty damn good. Anyways, just another picture to look at. :b

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

 

[JoelTW]

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)

Maybe I did the port wrong or something

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.

 

[JoelTW]

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 )

 

[Frank Carter]

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

What's the tuning frequency?

 

[JoelTW]

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

btw here are some construction pics


I actually have 8 holes now


That was before getting the port in

 

[Allen Ross]

very nice, i like the carpet, adds a nice touch to it

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!
