Conical Horn with Markaudio Alpair10 FR - Page 4

jannes · 27th March 2011, 10:34 PM

I've been eyeing these Conic's for some time, and now the Alpair 10 has been succeeded by the 10.2. Would it be possible to use the new drivers as drop-in replacements? Or will the cabinets need to be modified?

I can't tell, because I gave the cabinets away, sorry.

to make optimal use of the gen2's deeper bass the best would be a different cabinet, but then again it might just sound great, maybe adjust the stuffing, in this cab (which were not originally designed for the Alapir10 in the 1st place)

Would acoustic foam like this be an alternative to sonofil for this horn? It seems like acousta-stuf will be very hard to use since it's not made in sheets, and the damping material has to be glued or stapled to the ceiling...

Acoustic Foam 1-1/2" 24" x 18" UL 94

I'm not an expert on horns, but I guess it depends on where the damping material is, if it is "volume damping", so in the middle of the box I would guess it is not a good alternative.

I found no problems with the wool type material, just a few staples of a little glue on the wall is usually enough to keep it in place.

My contribution: a slightly more detailed plan. I changed the measurements to inches and rounded when necessary. I hope they're close enough not to compromise the performance of the horn.
