Yes, too low efficiency, even worse than Altec 515, (when loaded with small throat, in proper FLH, NOT A7 type "horn" which disqualified it also for my usage... I don't know how "colored" Tannoy would sound with properly designed...

The Danley idea - or something quite like it - does look good for LF, but maybe less good for MF and up, I think.Which takes me back to the whole "point" of the imaginary "single driver"...Effing around with mix-n-match "systems" back in the day...

Jessie, your post catches me thinking about multi-channel driver matching, as well. I am not familiar with the Fanes, but I wonder if simply throwing more power at them would make them nothing more than louder, so they would then "match" the res...

I do not know Bud. I report only what I see and I believe in what I experience. Almond all SETs that I personally have heard the Lamm ML2.0 had the widest subjective frequency range. I did measured how ML2.0 clip and it was at 18Hz at the bottom and...

Hello again kitty...Analogous to the lack of perfect "audiomoron" transparency of something like an L1 or tannoys or koetsus, I can see the general direction of your thinking regarding the "oops" nature of developing a musical transducer in room.The ...

Oops, that last reply of mine was intended for Romy's post (the phone rang, and Paul added his post before I got mine sent...).
When I rewired this place, I didn't know for sure that what I was doing was entirely necessary ; Paul's writing on grou...

I'm not sure if the Salamander-style rack (wooden shelves supported by nuts and washers on threaded rods) will support 800 pounds, but if you put heavier items near the bottom then a wide heavy-duty version might be fine. Besides Salamander, some ot...

Well, let call it Slav music. All Russian composers of 20 century were in one way of other took the torch from Rimsky-Korsakov. Ironically I’m not a big fun of Rimsky-Korsakov’ symphonic music because it is too Slav, overwhelmingly and insultingly Sl...

Truly unexplored in the field of bass horns. There are zillion of new composite of syntactic light and very rigid material out there that might be a good candidates for building horns. People nowadays learned how to make good performing carbon fiber ...

[quote user="drdna"]While I think a resonating speaker can add its own musicality to a reproduction, it is clearly adding harmonic distortion, etc. It may be pleasant, but you run the risk of needing differently tuned speakers for each type of ...

Bud,Thanks for pitching the A45a and FR4.5, I never dealt with both of them and will consider them, though it is slightly disconcerting that all those drivers meant to be wide bandwidth and therefore have too much HF in them. Still, my initial candid...

[quote user="Paul S"]You have mentioned that you want a much larger enclosure for your oops unit. I was then wondering if you aim to merely broaden and/or lower resonant response or if you planned to in some way tailor resonance as it rela...

It was an audio eventful year and I have experimented and discovered many fascinating things. Here is a brief summary of the 2007 audio-events and a short look what my audio happening will might take please in 2008.

hi Romy. Nice topic! I have a very nice memory. I started very young, supported by a friend who tought me a lot and gave me books to study. I learned the basic formulas and started DIY speakers from purely technical perspectives, graphs, math, calcul...

Oops, I almost forgot the size of 14”. This is kind of off the wall size but still there was two exceptional drivers in this size that I met.
The first is JBL 1400ND. The 1400ND was initially used in JBL K2 system. It had underhung voice coil, neody...

I do not know what the Fs of the drivers that will be using. I did not measure them yet. I have one of them in ¼ cub feet box with a port making 65Hz and two of them in 1/2 cub feet box making 38Hz. If I found more of the them then will be unit...

For the sake of helpfullness, I think that we may separate the differences of the ported speaker designs of myself and Petar. What I have described is the standard, pedistrian model of a vented speaker. Petar's is a hybrid aperiodic-...

Here is an interesting, atypical nowadays, attempt to get 45Hz. With massive (not plywood construction), use one diver instead of two drivers, use better drivers and with proper tuning of the back chamber (it is wrong there) it might be a ...

Romy, Just a few notes.... I did use the term "crappy" in the connection with the tonearm in an ironic sense. Have you lived so long among US Americans you lost your sense of irony? Also, i do not suggest crappy Phonostages, merely ones with low inpu...
