Why not horns?

Here is a link for the AH300 horn in the OMA speaker.

A pair of these horns is $2700 in plain maple with a small upcharge for other woods. I believe I paid an extra $150 for cherry.

You can have the aluminum horn throat customized for any driver you wish to use at no extra charge. The B&C drivers that I use sell for around $1100/pair. These numbers are not chump change but they really are a bargain. I combined my horns with a pair of JBL L-200 cabinets (usually $1000 - $1200 per pair used) and a DBX Drive Rack PA for $400. Beyond this, all you need is 2 amps for bi-amping and some time, effort and experimentation tweaking the many variable settings on the DBX. If you do the math, you'll notice you are pretty close to 10% of $53,000.

You may notice I didn't mention a tweeter. That's because you probably won't need one but the B&C driver is a coax and there is a concentric horn tweeter included should you want it. That can be crossed in passively or you can add a small amp and tri-amplify.

The performance level of this speaker will blow your mind.

Is there a sonic difference between a fibreglass cone and a wooden cone? if so, can someone please explain the benefits and or negatives of both materials? (one benefit with fibreglass is I suppose there is no chance of it getting attacked by woodworm,lol). I think my cones are made of fibreglass, although I am willing to be corrected on that.
Johnk- did you ever dabble with wooden conical cones?

You have a triple alnico magnet magnesium dome tweeter, a ceramic composite cone mid alnico mags,paper cone woofers. I have listened to a few wooden cones and there are better about. So many types of cone material. Sure some are better than others. But its the total design of the transducers not any 1 part that I consider when designing loudspeakers or ordering custom build audio drivers.

why not horns???
too damn big

Vernneal - That's subject to personal circumstances. My horns are 24" wide by 21" deep by 52" tall. Not small and not enormous. Because they are back near the front wall, their space consumption isn't particularly egregious, however, the 18" diameter horn mouth is pretty eyecatching. In other words, the aren't really too big but they are pretty conspicuous.

Given the need for space behind them, I would say that most panels are effectively larger.
