Audio porn as requested the annular phase plug is funky

A for the horn I'm really not sure. I can get a pair of 8 cell (50cm x 27cm) for 180, The Faital Pro plastic job for 80 a pair, a pair of 400hz Tractrix Horn for 160, or the full JMLC-400 for 380 a pair.

The Faital Pro horns kinda seem a waste of 80, if for just over twice the price I get the multicellular horns. The 8 would be a cool place to start and are good value from what I can see.

decisions decisions.........either way I get the horn

I would happily try it for that kind of coin, especially when the real thing will set you back well over a thousand dollars, before shipping.Cool phase plug on the Faital.I have noticed that some of the JBL horns compress the entry of the horn, getting smaller before expanding agin. Kinda like the mouthpiece of a real horn. It looks like this phase plug is doing something similar.

It appears to focus the sound into the mouth - i think

Any Altec multicell would kill me financially. 200 or $320 is a steal. I just need to figure out how to finish them. Nude MDF wont make the grade at home for long

MDF is the a wonderful choice when you want a beautifully smooth, painted finish. Many furniture folks use it over wood for this very reason. wood will sho grain,even when perfectly sanded. I know someone who can tell me exact method for doing so and I can attest to the quality of their products. Ill let you know, if you are interested.

Dont know about the phase plug, but the jbl horns are done that way for loading, I believe. I wonder if Faital just chose to do it internally.

Well, you know me, I'd choose the multi-cell horns.

I think there are some good threads in the construction section about smooth finished on MDF. If not, Mr. Google should find you some.

I am leaning that way Pano!

It wasn't so much the finish on the plain MDF as painting the throats etc and the polyester foam filler.

I found a guy who says make up a jig to support the cell uptight with the mouth mount on at the bottom. Paint inside the cells fairly liberally and excess paint will drip thru the mouth and into a paint pot underneath.

As for the polyester foam I guess I could cover it in multiple layers of paper and then paint, or maybe a cheap veneer then paint. I've seen some of these horns with cork over the sides that looks ok

what thinks you?

Hmmmm.... not sure, as I am no woodworker at all! The tar filled horns had a tin skin over then, so appeared solid. I guess you could do the same with very thin plywood, veneer or even wall paper. Could give it a nice uniform look without too much trouble.
