Skushino. Yes TH is designed to play 2 octaves and no more, this derives from the design which actually uses a labrynth, in the shape of a horn, to return (and amplify) the back wave of the driver to the front and add its strenght to the output, no...

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...

Was invited over to Romy's today. Spent two hours going through recordings. First, I hear differently from him. At my age,76, I had a hearing test that showed oversensitivity in the 1000 to 6000 hZ range, and quick drop off above 10,000 Hz.Second, I ...

This is our first offering; we are indeed working on another two higher priced models. One will have an additional channel on top, the other one will be front horn loaded down to 40 hz. Optional finish and colors, both for horns and supports, a...

The initials post was the body of email that Kostas sent to me and considering it’s format he presumed that I will me post it on my site. So, I did it (with his permission). I ran all those tracks once (some of them just a few seconds) and below is v...

[quote user="haralanov"]Ironically or not, I have no practical problems with it, simply because I’m not using big UB horns. My upper bass channels are much more compact – 4 very massive 15” drivers with no horns. Their integration to my main widerang...

[quote user="Murataltuev"] Now it is
clear! Thank you, Romy!Today I auditioned and measured GOTO with closed hole in
back chamber. Mid-bass completely disappeared!
With closed back chamber it works efficiently
only from 200Hz! So, I'm going to tr...

[quote user="Joe Roberts"] The L-9 enclosures were wood on all sides. Sealed box. No ambiguity here.Wings were common on theater speakers for mid-bass reinforcement. Plainly audible improvement on these and, for example, A-7/A-5 VOTs. It is equivalen...

[quote user="msaudio"] Every frequency above 80 cycle's should be coming from the front of your listering position, next to macondo. [/quote]thats correct the worse thing you can ever do there would be trying to get your upper bass 80hz above from t...

This gentleman's set-up makes me think very much of the one I have in mind for my new room in due course. Whilst as Romy points out, the room might well be on the small side, it has a very high ceiling (say 4.5 m) that in my mind always presents fabu...

Hello Romy,What brand of 0A2 do you use in your phonostage?I used RCA, but after 1.5 years of work it began to spark when phonostage is switched on.I tried Siemens, Mazda and now Sylvania 0A2.Siemens has "disco sound", without mids, just metallic hig...

Ronny, it is funny because I was juts about to carve my further observations about the Sound of my monitors. Last night I was listening Rigoletto by Callas and Gobbi on my monitor. I come to an interesting observation that I would like Monitors...

Would not a 9ft-11ft long bass horn path (tapped horn or any horns) cause a sonic problem if not physically time aligned with the upper bass or mid bass channel? The only way to fix that would be to place the bass horn 9-11ft closer TO YOU than other...

We have two models with different upper bass horns, one is indeed a 140hz horn (77 cm diameter) and the original, bigger horn at 110 hz (92 cm diameter) Both tactrix both made from the same materials (MDF) and finished in the same automotive finish.T...

Dear Romy,If you want to post some fragments, then perhaps Playlist 07; Song 03 (bypass) minutes:seconds 4:08 - 4:46, 4:46 - 5:37 and / or 16:30 - 17:12. We are discussing upright bass. As I recall, they should would produce a f...

Good points Roman. Thanks!!. I already decided that I'll build dual channel amp with those "crappy 300b's"(as I already spent my winter shoes and vacations on them) tubes and full range Melquiades when funds allow. Did you say "mid-bass" in the cont...

Murat,
I am not qualified to talk credibly
about Tapped Horns. I know that they get a lot of traction now around audio
people but I am, without listening a good example of it, am not so warm to the Tapped
Horn idea. The comments of yours that y...

I've only had the pleasure of listening to 'professional' horns (whatever 'professional' really stands for)--horn normally used in concerts and small venues. (It was always so obvious to me--by listening--that the range of the horn-loaded 'bass...

[quote user="nl"] Within that horn-loaded range, the 210/515 type combo does reasonably well, and produces rather more inspirational midbass than most direct-radiator type strategies. There is a reason why these designs persisted for roughly forty ye...

Hello Romy, thanks for your guide.I've been thinking and I feel that some basic upper bass channel ideas are forming; they a result of, as you say ,"organic" derivation from the rest of my acoustic system. I am pretty excited about this idea i have. ...

I’m new to this outstanding website and I found it has really educational value and antimoronizating information :)
I’m still in the world of direct radiators and I’m looking for the ultimate midbass channel solution. At this time it’s still impossi...
