Good to see you back JKRO
Make that paper cuts filled with wall paper paste - my movements on this have been minimal since adding very carefully weighted out quantities of pluff to my 12lta's.
Time to bribe carpenter to make me my horn jig I guess.......

I have found a friendly, local, laser & water CNC equipped engineering firm. Once I get the proof of concept out the way I'll get a perfect template cut.

And as they can cut down to 0.5mm steel/copper/stainless/brass sheet, I might get a price for a genuine one off, all metal, silver soldered or brazed multicell kit

Ok, so its not progress in the way I was hoping but I've ordered my miniDSP so at least I'll be able play 'once I get some damn horns built'

I have new tablets without sedation so up all hours and very unfocused again. One of the side effects listed with the med? Sudden death!!! I kid you not. What the hell is the world coming to when a side effect of a med for MANIC DEPRESSION is sudden death?

Next step, clear the table to start work

On a side note. How do I match the volume of the horn with the bass? The horn will be 109dB/W/m and the bass around 98dB/W/m - thats nearly 4 times as loud.

Do I use the master vols inside the miniDSP? Should I reduce the highs alone, or reduce the highs AND raise the bass?

Any wisdom from hi efficiency horn loving lunatics appreciated

I was hoping to use my ACA 5w SE Nelson Pass midget wonder to drive the high end and a hifimediy 180wpc for the bass - how does that look?

Lower the gain on the horn amp. If it does not have a volume control, install one. I also suggest an L-Pad on the horns. For 8 ohm horn drivers try 4R in series, 8R parallel to the driver. That will bring them down 6dB and may be an easier load for your amp to drive.

Hey Pano - Could that not be done digitally inside the miniDSP? or would lpads still be a good idea

I've ordered the 'dsp volume control and will play between running that full and using the preamp control or using the preamp only or using the 'dsp control only
