FrugelHorn XL

Ash, from all I've read I think the Alpair 7M or 10.3 might be more appropriate for smaller rooms, however the 12P may work acceptably on an open baffle, which is a very simple arrangement that can give good results.

Go onto DIY.com on the full range forum,Where Dave Dlugos and Scottmoose post.Hundreds of designs and Dave is a great bloke to deal with.
I have been building full range speakers for the best part of forty years and there are some things they do that no other speaker can.
For small scale work and solo vocal they are sublime but they have very limited sound levels and cannot do large scale or Rock at all.
The latest seems to be FAST which is basically a full range augmentad on the bottom by a bass driver.
The sweetest I have ever built is a pair of ENabled Foestex 126 en which are nominal 4 inch speaker in a 6 foot double back horn,a Scottmoose design'
The smaller drivers seem to be much better,being much sweeter and not beaming as much.
I have a couple of CSS 4 inch speakers if anyone wants to give them a go,as well as 2x CSS sdx7 which are as rare as rocking horse poop as they are now out of production.Dave Dlugos swears by them.
I also built a pair of Beta test boxes designed by Dave for testing fitted with Audio Nirvana 10 inch cast frames.They beamed like hell ,were very uncouth and my son now has them.

The best full range by far is the Jordan Watt Elkona.I have a pair in Townshend Glastonbury cabinets with Townshend original supertweeter and they are sublime.They have the sweetness in the midrange of a full range and will take the roof of the house if you so wish.
The cabinet is basically a MLTL.
Open baffles seem to have to be absolutely huge to work at all although I am told by Dave that Betsy K's in OB with wings can be fun.

Try the Frugel Horns in a corner to extend the horn and although they probably will still struggle with scale they will be sublime

Hi Ian,Yes ,quite agree about the forum but its still a mine of information.
The original Frugel Horn with Fostex never really floated my boat but I had some early 4inch MA's in an 11 litre spherical enclosure that amazed everybody that heard them.
Will be nice to hear how the Frugek Horn XL with MA's sound and perhaps they are a step nearer to a full range for everyone.
