Lowther drivers, front horn or back loaded horn?

Hi Jsadurni,

Thanks for the advice.
So, do you think that the compression driver does the same kind of inmediacy, low level information, reproduction like the lowther?
Which one is better in tone reproduction?
Which one has more "presence"? presence like feeling that the musicians are there...

I was thinking that can be an Azura 340 with throat for compression driver and for the low part of the spectrum, a bass horn or a bass reflex.
Which compression driver will you recommend me for the 340 horn?
My new room is 13 feet wide x 17 feet large, Im planning to put the horns on the 13 feet wall. I will seat at 12-14 feet from the horns, do you think is enough space for the waves to integrate and produce image?

Thanks

Alan

Gawdbless I built those horns, you have a t90aex a rare limited edition fostex tweeter and wonderful f200a the gent you purchased from put much $ into that system you got a great deal.

Hola Alanbrain,

Compression drivers are much more detailed and dynamic, with the wrong horn they can be punchy and have horn colorations, I am sure the 340 Azura horn will make the sound nice and full, the tone will come from the horn and the diaphragm.
Presence I would think is a combination of detail, tone and dynamics, so compression driver have these in spades.
With a 340 hz horn you will want to go as low as possible, I am sure you can get away going down to 500 hz, which is pretty low. If you want no trouble shoot for 700hz. Start loading up on capacitors to play around with Xover freq.
The most dificult part IMHO about a horn loaded system is Bass integration, go for a driver that will go up to 3khz or higher!!! Bass horns are really complicated...
Going down to 500hz limits the amount of drivers you can use but aids at bass integration, that low the usual suspects are JBL 2440 and gang, Altec 288 or GFA new ones, Beyma 800 series, Big radian maybe, TAD and of course GOTO and ALE, how much you want to spend? I think a good start is Altec or Beyma 700 series IMHO. Ask Martin from Azura to recommend a driver he knows works best with his horn!

Hi Gawdbless,

Your system sounds like a very dynamic one.
Tell me, the Oris with the fostex produce any ringing?
What is the distance between the horns?
and
What is the distance between you and the horns?
Have you compared to the Azura horns? Some people say that the Azura is made of heavier fiberglass and thats why it doesnt ring.

Thanks

Hi Jsadurni,

So, a 340 Azura with a compression driver all the way up.
And a bass horn or reflex from 40 to 400 but with a driver capable of going to 2 or 3Khz?
But, if a set up the crossover at 500 or 700hz Im cutting in the middle th frequency range of the human voice, am I?
So, just to understand, in that case is not better a Lowther that can go down to 180 hz, where it will be easy to make the crossover point?

Thanks
Alan
