As I learned today the Australian Martin seddon know as the Azurahorn Guy has a web site and he also does horns:

[quote user="haralanov"]Romy, the main driver in this acoustic system has nothing to do with the funny Lowthers. It is very high class field coil speaker unit made by Oleg Rullit. The owner of the system has tried the highest class of the Feastrex li...

[quote user="haralanov"] For some unknown reasons, he later decided to change it with the sharp and artificial sounding fostex supertweeter. What might be his motivation? Logically appears the following question – is that Goto supertweeter so hor...

OK, I am keeping my new The Loudspeaker(s), and I will be selling my large "Diamond Edition BassZilla" OB speakers that feature OB high-passed Lowther DX-4s running wide range (NOT full range!) over 15" Audax PR380-M2 woofers in integrated BR boxes u...

Decoud, you will only know if you try it, but my long experience with the Lowther makes me doubt its suitability for your situation. Perhaps there are other, more suitable single drivers, I don't know. While I have no idea at all what you want to w...

Haralanov, you might not get it from my actions, but I actually understand and agree with everything you are saying, in principle. At the same time, I have no idea how to address such a sharp peak mechanically, since adding mass as usual would just m...

Yoshi,What material do you have as damping material in the box and how close is it to the Lowther? These things are incredibly transparent to what is behind them. Some things to consider.If the damping material is within 3 inches of the cone, it will...

Dear Romy, thank you for your opinion. Did you see and hear them if you are talkig about the quality? In Munchen High End Exhibition 2016 Evolution speakers celebrates big success in demo with KRaudio Kronzilla amp.http://positive-feedback.com/show-r...

"Vitriolic" is certainly the wrong word to apply to my "attitude"/post(s), Dominic. "Amused" is more like it. I am amused by claims that ANY 4" driver makes a stand-alone "Full-Range" speaker able to "presen...

A little update on the Milq amp.After sorting some of the problems with the amps transformers (see posts above ) .I now have two mono blocks operational that have about 700 hours ,I'm so glad hour meters were installed .Filament voltage is spot on 6...

Very cool, James, it would be very interesting if you put your ears into an investigation of “Ooopsy back chamber.” I was wondering about the A45 Lowther as well. The 125Hz midbass horns that you made, how big the input hole in there? The attempt to ...

Hi The CatI forgott to answer your q, what I do.I 'do' management...heading up a team of folk for a large social services charity in Sydney. I cover training, occ health and safety, payroll, volunteering etc. We have 2000 staff.My interest in audio s...

Since I have struggled with my own +/- insurmountable problems with Lowthers, OB, BR, etc., ad nauseum, I can certainly relate generically to what you have just said about horn drivers in this injection thread.Yet this may be the only time I have hea...

Hi there
I can see Romy's face when he's trying to figure out Martin's time alignment strategy;0) I have Martin's 204 Hz horn with Fostex 208 E Sig. These horns are to be big to properly integrate with anything. They are OK with Fostex Lowther drive...

[quote user="guy sergeant"]Some of it, (the current speakers and some of the amplifiers) are in my view, not outstanding. Other items, (the big preamp, phono stage, cartridge, MC transformer, silver cables and largest power amps are exceptionally goo...

I'm very inexperienced but I still try to observe things around me carefully. Here's what I'm getting at what can be potentially pretty good.. Well, all I can really say is I've been mostly interested in the design implementations of companies such a...

"It is not an accident that I liked the article about the “Resonating Oops” to this thread."Interesting. I'm just completing my 125hz midbass horns. And I'm deciding how to construct the back chamber. I think I will experiment with a removable and tu...

Too soon to begin in-depth descriptions, but after a good deal more work (and expense...) than I'd bargained for, it did not blow up, and there was not the all-too-usual painful silence in lieu of the first expected sounds. I admit I was as surprise...

...It's about the Curve, Dummy!This morning I disconnected the notch filter and listened as long as I could stand it. Not long!Then, I went over my math and remembered that I went the way I did largely because I "already had the parts".After an extra...

Sorry, I couldn't resist the header...Electricity was OK today and either the X/O parts are already breaking in or I had a "lull" in the expected parts shut-down. Anyway, I actually wound up seriously listening to some serious music! Even without f...

James, why shall I hit you? The Lowthers do fine MF drivers if not to stress them into full range. I actually thought about Lowther but what I was looking at them I did not see any interesting 5” contestants. The new DX65 is 6.5-7 drivers and t...

"Meant to be?"
With 100.5 dB efficiency in quarter space I plan to use a dedicated tube amp. Yes, some people use high powered amps to see how loud they can get Def Leppard, but I don't see any reason to. And some tapped horns...

If I went to a Ferrari dealer and "kicked the tires", they would ask me what I am doing there. In the audio world, there are a lot of people "listening" to the Magico that are not doing anything else except kicking tires.Why the dealers/reps feed tho...

hi anthony, have fun with that, results are worth it. Your findings don't need to match mine but i share my favorite briefly :)I found explanation from an famous german engineer. Hes calculating an Rms thiele small to indicate mechanical friction los...

Well the whole write up i just wrote disappeared. In one sense that isn't all that different from my experience of the Festival Son et Image here in Montreal yesterday. i'll be quick this time in the hopes that my post will get through. bett-er rooms...

Greg, I have written about my "DEBZ" speakers several times at this site, including Post ID 3269, early in my original Lamm ML2 thread. I mention these speakers now to compare what we are aiming at here to what I have already done, wh...

Well, FWIW, my Audax LF units started life at ~100 dB and wound up closer to 96 dB to get ~40 Hz from them via ~ 4.75 cu. ft. BR boxes. Computer tuning was very close, only a strip of rubber weatherstripping in the vent opening between be...

Hi Romy, great site I just recently joined but have read your many posts over the years as I quite frequently end up here while searching the net for info. I recently purchased a pair of Super12 wharfedale drivers and thought with all your audio know...

Last week I spent a few hours at the scene of NY’s Stereophile Show – HE 2004: a half-day on Thursday and 2 hours on Friday. As many other audio-shows it had many semi-ugly colorations, however as any audio shows this zoo trip brought it’s own “inter...
