Why not horns?

The cost is the one thing I suspect I could not live with and would be the reason "why not horns" for me in this particular case.

Also there is a lot of competition at the $53000 price point.

Also it seems that very expensive speakers in general seem to depreciate the most on the used market as well which makes them a bad investment. People with the money to afford $53000 speakers are not searching for used bargains I suspect which means the prices have to come way down into the range of mere mortals to re-sell without taking a big financial hit.

I meant to say prices have to come way down to re-sell which means the owner will take a big financial hit if they re-sell new big bucks speakers.

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.
