I am very excited to start this tonight.. it is a wideband dipole 2way and will be self powered on the dual Acoustic Elegance 6's with twin 10" pr's, but also dsp driven with an additional dsp output for what ever amp you decide to run the Lowthers with.
This allows full adjust ability in the digital domain for crossover, eq, and time alignment, but only requires you to use a 2 channel amp of your choice "SS or tube" and not need multiple channels of amplification and still allow a fully active solution.
This piggy backs off a set I just built for a local client...

lovely work above....
are you sure you want to use AE's for bass? Have you simulated that? I ask because they really don't dig very low. You could slap a 10" woofer where you have the PR currently and be fine as long as the lowther gets down to 200Hz.

Thank you for the compliments..
After many nights bugging Jon at AE, we came up with this solution.. he's very confident I'll get strong mid 30's and still be within mechanical limits... and that's fine by me as a little EQ message will help... and who these days don't have an additional sub..
So, don't mind the messy board as it's just scrap to make the initial jig. All dimensions are accounted for, a minor bump out on the back was made to accommodate the 2 x 250 amp and dsp board. And make it 2 inches taller then the original Blackmore. I'll have to redraw the side insert when I get to that point..
All the spacing was done for the new Acoustic Elegance 6.5's along with the 10" passive radiators.. This is going to be allot of fun!!!

Nice design!
May I suggest that you make it dipole all the way down? You have room for three 12" or maybe even four 10" below that Lowther... 🙂

Thanks!!!!!
The reason for this driver choice is that I want to keep a very slim profile and John's 8's won't be out for awhile 😀..
But, the dipole Lowther has ruffled enough feathers I thought why not ruffle some more... plus the dsp will allow me to place a small shelf to help extension..
Would be curious what your curvaceous styling would come up with for a pure dipole as Stig mentioned - think of it as a design challenge to create something prettier than the jamo r909.
I have been trying to come up with an attractive DIY friendly solution for just that for John at AE for a few weeks now.. and I have come to the determination that it's hard as hell to come up with something simple..
So I have decided that anybody can take a flat board and cut holes and screw drivers to it with very little skill... I will come up with something that a person with above average skills can make and even add their own twist etc..
I'll post a rough drawing up with dimensions..
Randy, excuse the purely aesthetic nit pick on the otherwise elegant design and clearly very time consuming build:
had you thought about machining a chase in the layers of rear support member of the skeleton frame to hide the wiring to the Lowther?

The new design will have the wire hidden, which is what I wanted to do on the previous build, but certain dimensions with the holes and shapes prevented that.. Or let me say that I'm not a fan of trying to router to less then a quarter inch on a traditional router table 😱...
so while I am waiting on tool to get here on Wednesday.. which is going to make my life so much easier...
I'd figure I'd toss up both the color and the inlay material 🙂

So, some toys showed up on my doorstep today 😀... I love me some Dyn!!!!!
excuse the mess as this is just my break in rig...

so I couldn't just sit around.. lol.. baffles are rough cut and glued and ready to be routed. And the master jig is a 100% drawn and rough cut and ready for tomorrow 's date with the new tool 🙂 aka the mobile solutions shape stick
So 23 pieces per side with a mixture of 1/2 and 3/4 mdf..
Picked up all the material needed today. Finished cleaning up the Master Jig and created 2 more smaller masters for each section with a little router clean up needed still in a few areas. All that's left is to make the insert jigs and all the hard work is done. I also traced out all the pieces needed on all the mdf 🙂

Alright... this 95 + degree with heat index's of 105 plus sucks..
After 2 -3/4 inch sheets and 4 - 1/2 sheets of mdf all is rough cut and one is routed and glued together.. The end caps are just sitting in place as the baffle for the dual Dynaudio MW172's still has to be made, but you get the idea..
You can also see the dual 1 1/4 dowel bracing which worked out very nicely..
All the roundovers had to be extended past each layer to insure the shape held true and any imperfections will be fixed..

Like have you've dealt with the potential for internal reflections. Will you be adding any damping or is the irregularity enough on it's own?
OK... not allot finished today... just way to damn hot and humid.. plus I'm waiting on some more 2way tape...
baffles are cut-routed-and glued in place.. and I ran some fiberglass paste over a few areas.. all that is left on these guys is to do the inserts and then off to body work 😛
P.S.... yeah the pics are taken in my kid's play room 😛
