double horn 108 ? - Click HERE for Original Thread
brad212
Newbie here.

Double horns are gorgeous (like the Ben-I). What are the advantages? I assume more expansive sound and smaller footprint?

Anyone have plans for a double horn using the Foxtex 108s?
chrisb
Wouldn't the J-Low well documented by Nelson Pass be easily adapted to the Fostex? Maybe at least the folding geometry - it might be wider than necessary for bass performance equal to the factory recommended enclosure . (it's certainly large enough to cause some issues with WAF)

FWIW, Terry Cain has probably experimented with something close to this configuration, but might withhold some of the specifics to allow for potential retail product.

I believe the main advantage of double BLH's is the much improved imaging. Similar to a MTM configuration. Disadvantages of course being size.

Thanks for the reply/ideas Chrib,

Yeah, the J-low's a bit large. I'm looking for a small footprint. The Fostex recommeded rear horn is fine, but I sure do like the looks of the double horns like Mr. Cain's! And, I assume that the footprint of a double horn would be roughly 1/2 that of the single. Someone suggested that such a double horn with a 108 might lose significant bass since only 1/2 of the horn output would couple to the floor.

I've been advised to check out the Swan. I'm sure it sounds amazing. I'd just prefer something that looked more like a double horn Ben.

It'd be great if Mr. Cain could share some thoughts, but as you mentioned I wouldn't want to take potential revenue from his pockets.

Hey Joseph,

Thanks for the reply.

But with a double horn wouldn't you need to 1/2 the dimensions of each horn to maintain the correct volume?

If this it true, the speaker would be tall but the floor footprint should be much smaller?

Double horns do it! This fe 108 dbl horn is easily one of my favorite systems. Needs a bit of power not having the displacement as larger drivers. Organic imageing, great bass and fast. Firstwatt juiced creates total holography. Double your pleasure.

Love that new finish effect, Terry.

Very cool indeed! Reminds me of the classic sunburst Fender Stratocasters.

Mr. Cain,

Thank you for the reply - I am honored to hear from the man himself.

I'm actually awaiting the arrival of a pair of 166ESRs now. A friend told me Solen in Canada had a few left and I snatched a couple. So now, what to do with these little gems?

I know you are a fan of the Fostex recommended cabinet, but I would prefer something with a smaller footprint and somthing that I personally found more appealing aesthetically.

Since I'm a newbie, and have no idea what I'm doing, I'm trying to convert the Fostex recommended cabinet dimensions into a Hedlund type cabinet. When I get frustrated with that idea - who knows? Back to a double horn?

Mr. Cain,

I've made tls, ported boxes, closed boxes, esl but I am completely new to horns. I have much to learn.

If I went with a 166 ESR double horn, can I just add another Fostex recommended box atop the single horn? If I do that do I keep the throat and compression chamber the same dimensions? keep the driver in the same position relative to the chamber and/or throat? Can I decrease the footprint? Am I asking you to give away proprietary secrets? Should I hit the books? Do you have a book recommendation?
TC
You can double the factory design, will be very heavy. Keep the rear chamber the same volume or slightly larger (you can always add mass to make smaller. Stunning system like no other.

Hell-fire, now THAT is what I call a horn. If I had the money Terry, you'd have the cheque by now if I had to send it via carrier pigeon, and I don't care how much import-duty they'd demand from me.
One quick question by the way -any UK distribution yet? I think it's safe to say you'd get an enthusiastic welcome!
Cheers
Scott
