Single Driver Horn vs Multi driver efficient spker

Great write up Darkmoebius !
You should be working for 6moons! LOL
You've pretty much said it all...I feel the same way about the single drivers. I haven't heard a multi way I would trade for mine either.

Funny you mention the pressurization of the room. I thought it wasn't possible with the single drivers.
I was most definitely wrong! As mentioned above efficiency ,a little upper frequency energy and high output had to be traded to get it.For me it was worth it. The speakers still play cleanly in my room at 100 dB with peaks around 106 db. I never listen at these levels though. I'm normally around 75 or 80 dB. Also the shout some speak of is non-existant in them.The speakers also use correction circuits which contains a zobel network.This keeps the rising impedance/high frequencies at bay found in most single drivers. While in turn taming beaming and shout.

The speakers frequency response is the flattest I've heard in my home. I'm getting near fullrange sound from maybe 16 or 17 khz down to usable bass in the mid 20 Hz range. 30 hz response is basically flat in my room.It's no lower in dB than a 50 Hz tone burst. There's also no 50 hz hump that's found in ported bass reflex speakers.

I was listening to some Jacques Loussier Trio "Gnossiennes No.5" yesterday. This is a dynamic track with kick drums,cymbals,upright bass. The Transmission line loaded Fostex F200a pressurized my room enough to make the room shutter. Not in a drawn out way. Very well controlled with the kind of bass you feel in your chest( Room size will dictate results).

A kick drum sounds like a kick drum and also feels like one.I have a friend who has two drum sets in his house. So I know what percussions should sound like.

I had my son in law over to watch a action movie a while back. I used the FTAs as the mains. Half way through the movie he ask me" What size woofers are used in the powered subs built in the bottom of those speakers ?".

There are no powered subs I replied, it's only a single driver. He looked at me with this extreme surprised look on his face. Then he got up and walked over to check them out. He could'nt believe what he was hearing.The rest of the movie he just marveled at what they did and shook his head.LOL

I have been communicating with another owner of these speakers. The FTAs ousted a pair of $5000 multi way Gershman Acoustics AvantGardes in his system! Yeah their that good..when setup properly and given proper components and break in time.

>I had my son in law over to watch a action movie a while back.<

Damn, Gymane. I wouldn't have thought you were old enough to have a son in law ;-}. Must be all that good clean livin'.

Glad you are still liking the speakers.

Hey Oz..I probably don't look old enough to have a daughter in highschool either.LOL..But I do.
Hell... I'm in the weight room or running in the park 6 days a week.:-)
My work out partner is a 50 yr old retired Marine.He can still run a mile in 5 1/2 minutes!
The FTA-2000s are here to stay.

Fostex f200a is a wonderful full range you should hear it in a larger TL without corective network.If you would want better sound add a raven r1 ribbon tweeter. I built a pair like this for a friend 5 years ago.System sounds wonderful makes me want to build a pair for myself.Iam using my f200a in a azura front horn with t900a and dual eminance 18in woofers in giant back horn system is amazingly good.Thinking of trying f200a in front- back horn cabinet next.For years I was importing 60% of the f200a brought into the states sounds like alot but it wasent realy that many ,no one was using this driver, fostex was going to drop this fine driver but I bought up a bunch and they resumed production.Glad someone made a production loudspeaker using f200a.I have built 25 pairs of f200a based loudspeak many dif cabinet designs.Its a great under rated driver.

Kloss I have followed your threads for sometime now.
You have to be one of the for most experts in this type of speaker.Especially the F200A driver. Thanks for helping to keep them around! I took a close look at this driver out side of the cabinet. I haven't seen a better built driver personally. Man these drivers are MONSTERS!From all the fullrange or almost fullrange drivers I researched. The F200a seems to be the best bargain in high end, when it comes to a true fullrange single driver.

You mention the Raven r1 ribbon tweeter. What value capacitor would I use as a filter if I decide to try them? To bad I'm not closer, I would love too hear those monster horns!

It's a shame more haven't discovered these drivers and how good they really are.
Some get caught up in the glam and glitz ..That seems to be the only thing about this hobby I don't care for.Most spend too much time looking for a particular name than just listening to different products..whether well known or not. Many miss the boat looking for the big name in lights.
