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...

Hi Romy,
I am planning my own DSET build. I have based my speakers on your Macondo and
am busy turning MDF horns in my spare time.
Once that is over I will move onto amplifiers. I plan to build a fullrange Melquiades for a
friend and the...

[quote user="cv"]AlloI had a theory that the bug screen was helping to damp horn modes/refelctions caused by a mismatch between the S2 internal flare and the horn flare rate. I have 340Hz flare JMLC horns, which may be expected to give less of a mism...

[quote user="anthony"]I plan to
build a fullrange Melquiades for a friend and then if that works out the DSET 6
or 7 channel version for myself. [/quote]
That is very good approach in my view. The
problem is in this approach that you have t...

Looking at the variety of exponential, parabolic, conical, tractrix, hyperbolic and whatever ales horn profiles out there I was thinking that we probably incorrectly approach the entire subject of horn profile analyses.
We listen the horns and we fe...

[quote user="Ronnie"] The room modes I thought I had to battle suddenly disappeared the other day when I decided to try stuffing the boxes a bit. Suddenly everything fell into place :-)I guess I can do better than using little cushions though... Do y...

My COVID-19 brain fog has finally lifted. I have been using HORNRESP as the gold standard for horn design. Upon reflection I forgot that we ultimately listen to the sound produced and not the beautiful computer simulated SPL profile. So I ...

[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...

Hi Romy and othersI am in the initial stage of planning a new home, which will have a dedicated music room. I noticed Romy in another thread you were impressed with the rough stone walling. This looks like a great way to disperse reflections. What I ...

I think it is very interesting subject and I’m looking for first hand opinions by people, using properly sounding upper bass horns in their listening rooms. I’m not interested in theoretical opinions – only by opinions, coming from personal listening...

This is an interesting metal exercise – what would be the most beneficial for audio public and what would be “signaturial” for a manufacturer. Since the company do not turn the horn as most of the people do but use CNC machine then it would be very i...

Paul,The two channel system is separate from the HT system - the gigantic plywood folded horn subwoofers support the screen but that's the only connection to the HT audio system.The HT system is three Orb Audio 8" powered subwoofers, 3 x Gallo Ref. S...

At first I plan to power the thing SET, with a known, existing amp (a triode wired EL84) which I've already built and know the Sound. It is not bad, but a little "warm" sounding (second harmonics, and is low powered for low frequenci...

My idea is a upright horn like your "midbass hanging thing", at 200 hz for the smaller size of it, and this will be my work for 2009/10. What I would like is exponential curve, not tractrix horn, something like this one...

I am going to show two different simulations for a 105Hz
tractrix horn with the same 8”driver (B&C 8PE21). The parameter
values for these two simulations are quite different. However the
simulations predict the same...

Chirag, First off all you have to define what do you want from them. If at this moment you’re looking for something within $700 then very next year, when you finish you medical school you will be searching in very different price range… :-) Now a lit...

Hello Romy!Cessaro had severe resonance problems in their room, so I didn´t stay long here. What I noticed in the short time (maybe too short for a qualified judgement) was no stabiltiy broblems but less musical than the 300B last year. Hard to descr...

Well, I do have 3 channels of DSEP. Dedicated Single Ended Pentode: one channel (bass/mid 30-500 Hz) with a 307A DH pentode feeding two wonderful Fane neodymium Colossus 12" - one from FS to 150 Hz and the second from FS to 500 Hz. OPT with a lot of ...
