In reply to my post:
[quote user="Romy the Cat"] The epoxy carbon-kevlar and glass fibers staffed with damping? I wonder how more fun would be if they staff these hollow horns with sand, I would…. I had once an idea to have a very soft sand horn usi...

Wonderful horn, Chris. 160Hz is very-very interesting size for using S2 at it bottom knee for a lover mid-range channel. I when to 250Hz (I did not go lower because some my own reasons) but I think the 180Hz should the perfect frequency. With damping...

[quote user="jessie.dazzle"]As for balancing the amplitude between channels by driving them from different taps: I drive the upper bass horns form the 16 Ohm taps, and everything else from the 8 Ohm taps. An 8 Ohm versoin of the upper-bass driver...

Some have been used to build box speaker enclosures like aerolam (aluminium alloy I believe), which are pretty dead acoustically, can be moulded and machined, resistent, light (that can be very convenient), and you can finish them brushed ...

OK, now I am happier as I did my duty and the back chambers are ready to be attached to the horns and to be lifted up. Yesterday I spent 5 hours trying to build the back chamber displacement that Jessie and my carpenter ...

"A tweeter positioned inside the MF horn"I wasn't sure how that could be done effectively but was looking forward to a creative solution. That photo image is not what I expected; on hindsight it is not a surprise. Of course one could rip the tweeter ...

In terms of the length of the horn, I'm allowing myself a total height of 7'6" (just below the average ceiling height of 8'). In regards to the mouth diameter, that's another matter. (It appears that I will have to build two [2] different...

[quote user="rdrysdale"]So how do you suppose the proper DPoLS can be located? With a system like Steve Schell and I are working with, everything weighs hundreds of pounds and to properly evaluate changes would take days, maybe even weeks f...

Romy i read some time ago, you said wood horn with a certain porosity on surface is best sounding. I doubt abought that, as i thought the differences of finish ore even material would affect sound in a way no perceivable. today i saw a thr...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

Impatience got the better of me, and I called two mates who prompty showed up yesterday afternoon and we hefted the second DSET into place on the horn stack. A couple of hours of connecting and checking things and it was all ready to fire up for my ...

Back to 2006 I had a thread “Adding one more spherical to Macondo.” The thread itself and the concept that it lead to - the Fundamentals Channel - turned to be a phenomenal success. I know, I know for someone it might appear like nothing but if y...

[quote user="Serge"] The SIlbatone room was very large. They played an Edith Piaf record on a mono WE16B (or A, not sure). They played it very loud which I don't like, ever. I felt the system was made to show dynamics and it did it. The dynamic r...

Sorry if this is OT - I could start a new thread but my post is inspired by the quote below - [quote user="drdna"]the lathe-work is rough on some of the horns. [/quote]I can't decide whether that's good or bad. I'm slowly working up to getting ...

That is exactly what I was counting at and it has happened. Measuring this morning the resonance frequency I saw that it dropped from 43.7Hz to 38.7Hz. That is very very good, though I expected even more drop for a 2-3Hz during next week or two. My h...

Is speakers like altec 19 have time aligned drivers? I think I have never seen in internet time aligned 3-4 way horn speakers with oken/jensn as a bass.Slowly I am closer to finish my first speakers with horns, the frame is adjustable (35-45cm drive...
