I am building these for a local friend.. They will use the Lowther PM6A in a very unconventional manner.. damn near dipole.. And before I hear about how this won't work or will sound like crap.. Well I hate to break it to those people that it does as it has been tested on a mic stand for a few months and it's pure magic IMO..
Here is the start of the Blackmores.. These will be painted a Lexus black and will have bloodwood inserts. I have all the pieces cut except the baffles.. 1 of the spines is routered minus the large round over still to come..
This picture shows it just sitting in the base jig. The base will consist of 3 half inch pieces of MDF..
I will be making a limited run of these with a change to incorporate a Lambda Dipole 12..
Hope you dig em...

To be honest, all the horn applications using various drivers even the Lowther left me a bad taste.. So much that I disliked fullrange drivers.. It wasn't until I heard an open baffle set of PMA6's open baffle that I learned that I hated the horns not the drivers..
Then I heard the guy who I am building these for, he had them mounted on a mic stand, and from then I was hooked.. I'll trade low end extension any day for pure bliss

after hearing a pair of Fostex F200A "naked/bipole" mounted at Bud Purvine's house a year or so ago, I'm not laffing
very nice emulation of the Lowther's basket casting on those frames
we already have a set on a mic stand playing down to 300 and then subs from there down.. I will be doing a set of these with a Lambda Dipole 12 in the not to distant future..
Fantastic looking frames, but how much bass do you expect to get from unbaffled Lowthers? I suspect SFA.
I'ver never heard good bass from a Lowther unless you build things like the monster "Big Fun Horn" or similar.

Nice work! How I wish I could do the same thing.
Say, with such handy tools and the ability of woodworking, I'd like to suggest a slightly larger baffle (or we may say frame here) for securing the driver -- the area around the driver is just enough to make smooth round-over and 'merge' the frame of the driver. The result would be a driver with wider flange and everything is smooth and streamline.
I've been thinking about that for quite a while....

Also create the room needed to remove the tunnel at the back of the driver.

Hmmm... let me put some thought into this as I plan on making another set and I like this idea... thanks!!!!

You can't really tell in the pick, but it has a very large chamfer in the back

Chamfer in the rear
I saw that in these two pics. The edge looks thinner at the near side and thicker at the far side.
