Alright musicians, I am once again asking for some advice. As you may know I design and build cabs. I have been working for some time on building a very compact, but very powerful bass cabinet. I'm using 8" eminence speakers (extremely powerful for their size. I feel like I have a solid design with good dimensions. Here is a picture of the raw cab:
Little Powerhouse

I would love some input. I plan on putting a tweeter in the upper right corner eventually and also possibly putting another port in it, but for it's size (a little under 2 feet tall and wide) it packs quite a punch and would work perfectly for small shows etc. Any design suggestions/improvements would be great. Also if you're in the Flint MI area I would welcome anyone who would like to come try it out along with any of my other cabs that I may have on hand! Thanks guys.

Looking good- how much does the cab weigh? What kind of ply are you using?

I've built quite a few of my own cabs in the past-it's awfully rewarding to build one isn't it? Looks like a good design, but do you think you'd be struggling to play a 5 string through those 8's?

I would imagine you have calculated and/or got all the Thiele measurements for that cab.
You can reduce the depth by using the correct porting(pipes or long slots)
Would love to try your cab but I am in the UK..never mind!!

tbrannon- the cab weighs around 25 pounds give or take a few. I'm using 13 ply Baltic birch on all of the cabs I build. Actually I've played my ernie ball fretless 5 through it and it sounds fantastic. The speakers really are unbelievable. I'm still toying around with the insides of the cab, putting foam in different places etc. My concept for this cab was to have all power/sound all concentrated on coming out the front of the cab really unobstructed and after a few different designs simplicity reigned supreme.

terryc- Yes I have a very handy albeit confusing program on my laptop that helps me out with that, although I don't always follow it. The best sounding guitar cab I built (see my thread in the for sale section) I used my own designs and what I thought would sound good and it paid off. I absolutely love that cab, it sounds very different than most (in a goooooood way). Maybe a better focus for this thread would be what would you like to see in a bass/guitar cab? I've been toying with the idea of building a cab with a 15" 210" and 28" speakers and wiring them all separately so that you can plug into each and just use that speaker or use all of them. That way you could adapt to any situation. Keep the questions and comments coming!!!

I've always wanted to build a transmission-line cabinet...

An isobaric with a couple of 12" speakers would be nice, I would think...

Nice looking stuff, btw.. :-)

Think Baby Blue. Take a look at that cab design as it is one of the best little amp/cabs that was made. Two eights and a five.

There is a constructers book which I have had for years - The Eminence Loudspeaker Enclosure Book, it has all the designes you could imagine, folded horns, guitar cabs and explains all the theory as well.
Gone are the days when you just put a driver in a box and hoped it sounded good but sometimes experimenting can get good results.
That would be one massive cabinet with those three drivers would need a fork lift truck to move it.
Nowadays we have access to all these components and can have a good at building cabinets, in the old days you couldn't get hold of quality speakers unless you were a musical supplier
