And Now For Something REALLY BIG

[ingvar ahlberg]

Care to name a few from your experience?

Imo the new drivers from Beyma and Faital with polymer membranes sounds better than anything else, actually on par with the best amt drivers.

Beyma CD10Fe or CD10Nd and Faital HF104, to me, ounds better than anything else, shouldn´t be x-overed lower than about 1500 thou, i prefer around 3kHz.

did you try the new HF100 against original older HF100 ?

warpspeed sounds like more than just good midbass to me

15FH520 ?
looks like the best 15" 2way contender to me

Thanks for the photo of the Onken W cabinets and the 15 cell horns. That's gotta be killer. I've never heard those two mated up, but it should be wonderful.

You can do a 2-way with a 15" and 1" driver, if you pick the right ones. 18" and 1" is harder, a 1.4 is a better mate. Look for an 18" with a benign top end, that's important. Most have a nasty peak at the top. (So do many 15s)

No, haven´t tried the new version yet, my stock of HF100 was was quite large but not that many left now.

15FH520 ?

It´s good but i prefer the 15FH510, less peaky at 2-3k, stronger motor, Bl 21,3,
also imo the new ferit series from Faital sounds even better than the neo versions, same transientresponse but with a "darker" voice, and cheaper too.

The 15FX560 is also a very good driver for 2-way, but cost quite a bit more.

Hey Pano, here is the article with a few more pix Onken W & Altec 1803 . Do you think this 8 cell version of that horn i linked to earlier is any good? 8 Cell Multicell Horns for JBL,Beyma,Altec

I could go HF104 or HF144 on the 8 cell and use the Beta15's I have for now. Then swap out for better drivers a few months later.

If I use the minidsp I can muck around with crossovers to my hearts content or are physical crossovers the preferred method with horns?

considering the price, Iwata 600 looks quite good
like said, study throat area very carefully, it should to be 100% smooth
get the new HF100, its only 37GBP
just look at the smoothened impedance curve, and you know why
new one have wider magnet, old one have magnet and house of equal size

Am presently building a 97+dB 1w/1m system for a customer, four 10" p audio woofers , 6.5" eminence mid and 1" eminence horn, 200 litre 1.8 metre tall boxes, should go down to 40Hz, might mod the mid to sound cleaner, will post pics when finished.

Hey
Good luck with your project JR.
I will be doing a MCL-MRP4 this winter(master reference prototype 4)
I have aquired all my parts now...
These will be configured in a W.MB.M.T.M.MB.W
All active with a Bryston 10BLR in 2-way stereo and a pair of PMC modified(whatever) 10BLR's in 3way mono.
Krell FPB 600c on lows
Krell KSA300s on midbass...(for now although a 200s would suffice)
Theta Dreadnaught(4ch) on mids/highs...(for now cause I have it)(tubes later)
4-JBL 2245-reconed and doped
4-JBL 2118(BNIB)
4-ATC 75/150"S"
2-SS 7100
2-SS 9700(rear fill)

So I have been watching this JR...Good luck

There don't appear to be many projects on the scale of these $$$$$ giants, and understandably so with WAF, room size and cost etc to be taken into account. But what if..............?

Maybe 2x 15inch Eminence drivers for bass up to 100-150hz, a decent 10inch mid (recommendations?) up to 1000-1300hz, then maybe a paudio 2 incher on a 2380 cloned horn up to 8khz-9khz & then ??????????

How could it be done for a reasonable price (comparable to the JBL's)? What design concerns are there with HUGE 4-ways (assumed active)?

Let your juices flow in a mental exercise in excess - you never know, someone might build it?

This is my conceptualization of the ultimate end all large speaker.

A kind of hybrid between the Elsinore the Gedlee and the Beyond the Arial.

Using 4 12 high efficiency woofer drivers and a integrated type of 1.4 large format horn. The system would probably need a tweeter also (not shown in the picture). All four woofers cover the bottom octaves and the upper two cover the mid/bass region. Not extremely big at about 20 inches wide by 68 inches tall and 28 inches deep. But very good sized.

The goal here is to have a total system sensitivity at or above 100 db.

I will be starting a new thread about a TL woofer/Horn combo. Trying to dig up my MJK files and cant find them, but I have contacted him about it.
