Hi Ron,
Have you had the opportunity to hear the Yamamoto DC 300B and 45 SET amplifiers? If so, could you give us a comparison between your 45 SET and the DC heated models by Yamamoto?
And finally, what would you consider to be a good horn three or four way system that has the mid-bass through treble drivers horn loaded and uses a quality bass reflex or better sub-bass design? Price no object to a realisticly priced system that can be bought on the used market for the cheapskates and poor audiophiles.
I am looking forward to your reply.
Thanks
Norris Wilson

The speaker question is about as complex as it comes. I have a 3-way, and it is going to get a bit of an update soon.

Bass: JBL 4560 cabs loaded with EVM-15L EV's

Mids: Fostex FE107, horn loaded with 18" axial length, 30-degree included and a 2" throat.

Top: an old R-S horn. Not all that efficient, but it works, and has for a long time.

Updating the mids to an AlNiCo RCA compression driver, and I'll re-make the horn so as to compliment the old RCA.

Itching to try a ribbon for the top. One of the more affordable will be adequate.

This can be assembled quite inexpensively. Nobody has said it sucks yet...
cheers,
Douglas

Douglas,

"Mids: Fostex FE107, horn loaded with 18" axial length, 30-degree included and a 2" throat."

I just finished a little 6L dual port FE107E. Right now I'm using it full range as an office system. I was wondering as to what crossover points are you using your horn? I really like the mid-range of this speaker.
When used in your system as a horn loaded mid, is it capable of "party" levels? There is just too much break-up when playing high volume levels at full range for me to tell if it's worth putting this driver into my main system.

Is the:
"Bass: JBL 4560 cabs loaded with EVM-15L EV's " the same ones that you had in MD?

Regards,

Pete.

Hey-hey!!!,
The system only has ~12 W behind it. It has no problems with high volume. I bounced the cone off the throat plate when I crossed it at ~400cps with a 1st order series cap. The horn unloaded, and excursion went up.

Right now it has a 20 uF series cap as its x-over. An old PCB GE AC cap. This puts it at ~1000 cps or so. Single L in series with the 15".

The 4560 is like the Altec A-7 bass bin with a slightly smaller volume. The 12" BR boxes I brought to MD are still in action from time to time, and are distinctly diffferent from the bigger JBL's.
cheers,
Douglas

Norris,

Good to hear from you! I have the amps listed above and they are a close match to each other with the Yamamoto being slightly better(and only slightly less powerful sounding).

I will try and be more descriptive in a future post as free time has been limited lately with domestic/family issues.

I am using the EML 45's with the Yamamoto and they sound great!

Ron
