Couple little changes. Took out all the egg foam stuffing and fitted a few pieces of dacron stuffing to the middle of opposing walls like suggested.



Added foam gasket to the drivers.



And changed the old bolts to stainless steel. As the old bolts were just standard black ones and had started to show signs of rust. 



Will test it out soon and see if it sounds any better like that. Thanks again for your help people.

I remember a friend of mine making a similar cabinet in the early 90s. All we had to go on back then was a "Loudspeaker Design and Construction" by Eminence.... Anyway, he wanted to add a little more flexibility by porting it like yours, but he added a thread to the pipe and capped it so it could be used as sealed or reflex. I can't remember if I ever listened to the difference, but as someone else said you might be better off trying that cab sealed with some eq to the bandpass.


I've been meaning to try out what Brazil can bring to the party myself, but it might work for you!

Yeh id be lost without this forum, i couldnt of done anything just from a book haha. Fairplay for doing so though!

Ah yeh i will give that a go too with trying it sealed. I guess i can just bung something tight in the port to test it out to see if it like it before commiting?

I have a dsp the t.racks one seems real good. I guess that one in the link seems similar?
This one:

I'm only suggesting you consider an automotive solution because its likely to work better on a wider input voltage range like your car amps, can be used standalone, has more outputs and can provide a higher voltage output.
Fyi, the same company does a range of chargers/DC psus which I've found quite interesting. A 12v system is great until it runs out of juice and those products can power a lot of amps and charge multiple batteries simultaneously.

Doesn’t have to be anything special, socks or jumpers work for blocking the port.
