Lowther dipole 2way

[trusound]

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 ...
