I’m not sure if anyone else will be interested in this, but I built some pro speakers for live sound designed by bill fitzmaurice. they were pretty fun to build and sound fantastic it was nice to have my woodworking job blend into my audio tech job a bit while I made them :)

Here’s the middle ones in their cases

Sure I am interested. It looks like you have 3 different designs in the pictures?

I’m curious on the first design, is there any cancellation between the left and right portals? It appears the speaker separation (front to back) is eventually shared? Am I missing something?

I just bought a pair of QSC K10” speakers. I was looking to lighten my load. I play acoustic music so the big stuff isn’t for me. They sound pretty good for being as small as they are.

I’m looking to do an installed home stereo 5.1 or something like that? Haven’t settled on what yet.

Thanks for sharing your talents.

Damn straight I’m “interested”...just look at the avatar, man. A lot of woodworkers are musicians. In my case, I get to work with the exotic woods that luthiers use and make my home’s furniture look like high end guitars! Anyway, those look rock solid and probably sound awesome…are they full range or are they designed to be used with a crossover and sub unit?

Is the first one a folded horn design? I used to install car stereo and really appreciate seeing enclosures like this. There is hours spent on complicated custom enclosures and you really don’t know how they will sound until they are tested. That middle one is cool the way you used pipes to form the shape of the horn. Interesting, yes thanks for sharing.

Wow – nice work. Sorry – lots of questions – but I’m looking to build something myself… maybe not quite as technical as yours…
Why did you use ply instead of MDF?
What kind of drivers are you using?
Where did you get the designs?

@RonPeters- I do indeed have 3 different designs in the pictures, the top ones are tuba 30’s, the ones in the middle are the insides of DR 200’s (Might post the boxes later but they aren’t quite finished), and the bottom pictures are wedge horn floor monitors. I’m not quite sure exactly why they work the way they do I just follow the plans and they sound terrific. Fitzmaurice’s stuff often goes against the things we’ve all been taught about sound, he has reasoning but so far it’s been over my head.

@Konquest- The DR’s and Wedge Horns are full range but I use a crossover with the tubas.

@559dustdesigns- indeed the top one is a folded horn subwoofer, the most interesting thing about the middle one is that the driver fires backwards.

@Bullet- The main reason I used ply because it was lighter, the guy I built these for is getting older and cant lift around the heavy stuff like he used to.

They all use eminence deltalite’s which model depends on the speaker, the box is built for the driver.

The customer bought the plans from the site, http://www.billfitzmaurice.com/Ordering.html.

I was a DJ for about 2 and 1/2 years and i still have my speakers but i want some big 18” woofers, to go with the 15” i have. I love my music loud very loud. In my car I had about 3500 watts running through six 12” two 10” and a couple little four way speakers. Thanks for the post and site info, anything else on sound design for house or car I’m very interested in. It all comes back to woodworking somehow. ;)

I built his Table Tuba and am using it in my home theater (http://www.billfitzmaurice.com/TT.html). Corner loaded it is pretty loud. Does a great job down to around 30hz. I have a 15” folded horn I use for the sub 30hz.

Here is a pic of the folds in the table tuba along with my helper.

It looks like you did a great job on the builds! Thanks for sharing!
