Well I amlooking forward to seeing the thing finally done... and hearing it. Thanks for the good word on it, Brock. And I do realize that when something is good, it doesn't get 'un-good' just because something else might be a notch up!

Really need to get to it...

My experience...
I built an O12 too fast. Sounds AWESOME looked good then quickly looked ugly. Still sounds awesome. So, now I'm going slow and steady on my 15TB. Slow and steady wins the race.

A success story unfolding, sounds like. Me too, I'm quite well set up now for a build, and have learned a thing or two- I'm even going to alter the dimensions and use rabbet-joints instead of butt-joints. Just 'cause I can... and I'll incur the raised eyebrows of my carpenter-associates if I don't! :p

...And you can fix anything, as long as it's wood! Save that 12 cab and wait 'till you get some inspiration! Save it!

Alter the external dimensions to accommodate the joints, but keep the internal dimensions the same? I wouldn't mess with the internal dimensions if it were me...

Well you just add 1/4" to each side of a piece that is going to recieve a 1/4" rabbet. Viola, same internal specs.

You have to spend a little time with your cut sheet, making sure you don't cheat any sides- but all the internal pieces remain the same: You only 'mess with' the actual box ("enclosure"), not the bracing! :)

Loud, incredible mid-range presence, and able to get deep with the right eq. Worth the time and effort to build.

Used updated plans (05/14/2010 revision).

JoeVictim-

Purchased Tolex, grille cloth, corners, and feet from Gary at speaker builder's supply:

[Invalid or Expired Link Removed]

Can't say enough about Gary's great customer service - fast shipping and reasonable price (no affiliation, just a satisfied customer). Received the wrong grille cloth (black) with first shipment, but Gary made it right by sending what I ordered at no charge and let me keep the black with no extra charges.

Built the grille cloth frame from poplar boards I had laying around the garage - 40 degree angle for sides - to tight dimensions measured at internal cab front diameter.

The grille cloth frame is simply wedged into the front of the cab. No mechanical fasteners required based on the tight fit of the frame with the grille cloth fastened. The cloth holds the frame in place and dampens vibration enough that mechanical fasteners are not required. Gary has a nice tutorial on Tolex-ing and grille cloth application at his site's storefront.

Followed the instructions there and have no rattle or vibration from the frame.

Let me know if you have any questions.

Thanks.

Love a less-is more solution. :cool:

Just a report - I did a gig last night using my Omnistack (O10 and O10.5) with my funk band, and using it (with my Genz Benz NeoPak) as backline for 2 bands that opened for us. So I got to be out front and hear it.
Bassist in the first band was using a 70's P bass with flats and had that perfect "P thump ya in the chest" sound. Very different from the mid-hump fretless sound that I go for, and also a great sound. Bassist in the second band played an old Beatle bass - not my favorite tone but sounded good.

Essentially - the rig sounded AWESOME, with plenty of bottom (something I'd wondered about) and covered a wide range of tones authoritatively.

I enjoy seeing the cabs people are building and reading the gig reports. I recently put a PA system together so we'd have something to play out with. Trying to scrounge up a PA for every gig got old fast. I wanted something that was powerful with good fidelity but reasonably light and easy to move. It also had to fit in my GMC Yukon with my bass rig. After a lot of comparative shopping and hearing a few systems, I ended up at the BFM website and decided on a pair of 22" wide Titan39's loaded with Eminence 3012LF woofers and a pair of OTop12's loaded with the Eminence 3012HO and NSD2005 drivers. The Titan39's have top-rear cutout handles and heavy duty 3" castors for transport and bottom-front cutout handles for 2-man carry up and down stairs. I highly recommend both. The OTop12's have top hats for pole mounting.

With my schedule the way it is, my wife wasn't too keen about me taking on a large woodworking project so I contacted BFM builder Mike Roam in Austin, TX. We worked out the details and I put 50% down to start the build with the remaining 50% due upon delivery. I live outside of Houston, TX and Austin is about a 3.5 hour drive. This was key because I wanted to test the cabs with my gear before taking them home and shipping would have been a deal killer for a system of this size. Build time was about 7-weeks; pretty impressive for a project this size but I caught him at a relatively slow time and he knocked it out. The pictures below are of Mike in his shop at system checkout and the finished stack right before I loaded them up.

I run my BFM system with a dbx Driverack PA+ and Crest CA9 amp. This setup seems to have the right balance and works very well together. The Driverack PA+ provides a 24db/octave LR crossover set at 120 Hz for the subs and tops with limiter at 50volts for speaker protection. I'm a musician but not an expert sound man so I find the auto EQ wizard with 28-Band Real Time Analyzer for tuning the system very helpful. http://www.dbxpro.com/PA+/

This system has very good fidelity and dispersion and is very powerful. We've used it indoors and out and have yet to turn it up more than half way. Mids and highs are detailed and the bass just envelopes you. I'm very pleased with this system and can't see needing anything more.

You guys need to quit reviving this thread. I'm very happy with my Omni 10, till I see some of these other fantastic builds! I'm tempted to rebuild it (maybe banana yellow this time with matching head case), I know I could do a better job...or maybe a Jack 210?
