Interesting Small Horn Speaker

[sumotan]

Hi Guys
Found this in diyhifisupply store. Hi efficiency in a small package but need to augment with Subs as it goes down to only 70hz. Wonder how it sounds though.

Crescendo Ribbon Horn Speaker – DIY Hifi Supply

The directivity of the ribbon will not match up to the woofer. Not even close.

Hi,

No ribbon and supposed better directivity match:

P.Audio PH 230 1" Hochton-Horn

This makes me curious, regardless of whatever drivers are used, directivity will never match because of different operating frequency of each driver right ?

I don t see your point Sumotan.
Here is mine for the ph230/8": Ph230 have 90°x90° covering and cutoff frq of 600hz from spec. At about 1200hz they sould have reached the covering pattern so if you xover them at this freq or up it is ok for 90° coverage. A 8" should match 90° at around 1600hz/1700hz. So if you x over at 1,7khz or 1,8khz it should be ok ( from a directivity point). You may have to deal with break up though... depend from the woofer.

Aaah ok I understand now what you guys are getting at.
