Show your Bill Fitzmaurice cab

Bill,
I used the desgin for the Tuba 24 for the bottom half of this cab, using 2 10" BP101 Eminence spkrs, and 2 more for the top half, front loaded at an angle. Cab is 25" wide over all. The top half is vented through the gap in the face, and the spkr chamber has an angled back to avoid reflections or standing wave problems. Not sure if the design makes sense, but on stage I have great volume and out front the projection is pretty astounding. Your thoughts?

Rick

I think one thing Bill will point out is the drivers placed side by side.

I think if it was an XF210 design on top of the T24 that it would be pretty gnarly granted that they had a crossover and two different channels powering them.

Never place midbass drivers horizontally. There is no BP101. If BP102 those are good for the sub, but not for midbass.

Make another identical one for a typical old-school overkill kinda rig, and of course stack it on it´s side :smug: I imagine that 20 inch T39 and SLA pro could get together to one monsterous hybrid:eek:

Thank you...Hopefully I am a better bass player than speaker designer. I did not use a crossover...all 4 spekers are full range. My goal was extreme bottom end and it indeed does do very nice things for an open B string.Ah well, back to the drawing board.

Make it easy on yourself and go with two Jack 12's with no HF devices. :) -- missed the part about using it as a standalone guitar cab. In that case, see below.


Alternatively, build a fEarful 15Sub instead of the T39. Similar sensitivity through the usable range (when used by itself) and the flexibility to go up to to a higher crossover point as desired. Also, half the pack space.

I already have a T39 and I'm actually working on my second at the moment. I also have two SLA Pros. I don't really want to build another sub that I couldn't pair with my horns if I wanted to use it for DJ work, so the fEARful is out of the question. I think I may build a 15/6 for my friend though since he's been looking to upgrade his rig.
 
I'm considering making an XF 2x12 and pairing with a T39. It would make a killer rig.
XF210 will work better and is much smaller.

Reason #3 why I have a forum: Using it would have prevented these errors.
 
I need help identifying these! I know they're 15's, but which model. They are straight angels, not wedge shaped...sticker on back says 450 watts . 8 ohms... Bill?:confused:

Well, that rehearsal was different...first of all have to wear earplugs with this group at rehearsal anyways..fyi..

Cab in crazy flat to my understanding..I could actually use more lows..like sub kinda feel.. I didn't feel it as much as my Berg HD212..(it spoils me, I know) But I do actually like the mid voicing of the BFM cab..both of them should make a difference..

Bill could you give us a little more input about this cab?

I'm still glad I picked them both up though..;)
