Finished Sub

eag · 19th April 2006, 07:36 PM

So I finished my project. I'm new to this field so I made an undersized port, which registers an abundance of port velocity (on paper). I have a 150W amp ($50) on the back of this with a TB 8" ($30). Pretty good for $80 in materials. So the $$ was a success. The actual frequency chart was straight enough for me, not audiophile but it works (quite) well when I listened to it. I did hear some bad vibrations coming from the rear, but I think thats because I made the rear cut out too big. I hear no port noise, but maybe thats because the musics too loud.

My next subwoofer project won't be for a while, this will satisfy my needs. Its a good first project. Next time I'll factor in everything I missed the first time around.

How do you like the Tb8" Powerfull eh. It's nice to see that 8" sube these days put out so much volume / SPL

Its loud but at the loudest settings there are serious vibrations on the back. I don't turn it up to the loudest settings though so I don't hear them. In the future I will have to better seal amp/sub/MDF interfaces.

Jason, I don't know if we listened to mine with the two 8" PR's when you were here but they are a surprising little driver aren't they?
