The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...

Stereo Lab, to whom Romy drew attention at the beginning of this thread, offer their products on Ebay at what seem to be reasonable prices. See here (http://stores.ebay.co.uk/Stereo-Lab)Looks like the small horns are made of artificial stone, whereas...

Somehow the front runners in the horn field seem to have entered a time warp. At least we tried mightily to overcome/mitigate "horn sound", back in the day.With all the promise horns offer in terms of dynamics, all I wanted was a decent demonst...

It just ocurred to me to stir things up by posting here about the fact that my own DEBZs (somehow) absorbed 600W peaks during a recent Mahler 3 frenzy. I remember reading somewhere that some owners of the biggest Horning speakers would run them at 12...

R,More interesting observations there. Your Lowther thoughts are similar to mine - I always wondered what a lower flux version would sound like, but non-horn loaded and whizzerless a la Horning. Even got round to obtaining some magnet-less motor...

Hi Paul. Clear now. Well that "horn" actually adds a slight 6dB boost from 200 upwards, fading out around 1k. I assume that was just the missing piece to make most 8" driver (thats actually a fullrange) pretty flat up to the top. And likely what the ...

People never seem to run out of ideas to "improve" the stock Lowther, do they? Ironically, the newer stock Lowthers feature a rolled-edge whizzer that is supposed to be there specifically to reduce "shout" compared to the older/outgoing model t...

I believe that those "allien sounds" are an enhancement of the frequencies comprised in what is called the singer's formant, which is the area of the third formant when opera singers sing vowels. That area is in the range of 3.5 to 5.5 KHz and is a s...

I lost all hope for horn loaded Lowther speakers . Got Phile Mikey (fremmer) recommended TT and new old MC cartrige (benz Mc3) so analong front sounds comparable to old modded MCintosh CD player I have. I finished (took al ong time ) Hagerman c...

I have visited Sakuma's restaurant myself.
You don't need to travel to Japan to know that stock Altec A5s and Lowther-based designs from the 1960s basically run in the 70hz-12000hz range. They are in mono, and not particularly well-placed. That is...

BR, I have never used Romy's amp design, but I have used 6C33C SETs with Lowthers. I do not use my Lowthers FR, for reasons that are fully explicated throughout this site, so I don't worry about LF from those drivers. IMO, their best is MF up to tr...

Hi, Flm. Welcome. Try reading some long threads in our archives and you will get a better idea how to open a dialog. Pretty sure there are some Lowther threads, but no reason to limit yourself to those. "Accurate" in the case of speakers means faithf...

Mani, I have long run an 8" Lowther DX4 down to 150 hz, over 2nd order high-pass. My impression after plenty of listening is that I wish I could cross it at ~ 400 Hz. The "problem"is not simply how "low" the 8" driver will go but it is also a quest...
|
|
I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

Since I occasionally listen To K &K rakk dac unit and like it quite a bit I was looking at their phono stage for a long time. This phono stage is a little scaled down (in PSU) version of ART Audio Vinyl One unit which is very well regarded. Kevin...

[quote user="Romy the Cat"]Otherwise I would buy Warren’s Ikonoklast speaker with Lowther DX-4 driver and will be discovering how to “proporly” appreciate the Decca cartridge[/quote]Ouch!Did you have to mention the Ikonoklast speakers? Of cours...

The point of the field coil is to saturate the piss out of the magnetic circuit so that the coil flux does not modulate the motor. Romy, I suspect that your experience of them may be based on an older drivers where saturation was not the name of the ...

Hi all.I am just supplying a couple of threads that are dealing with application and the theory behind the EnABL process I provide information on here last year. Romy, you should not go there, it will make you crazy and you will have to insult someon...
|
|
Paul I have to admit being wrong about "BUdification" (enabl doted Lowther) process . I don't have explanation besides lenghty "brake -in " time but I would not bet on that. It may be a show stopper for you but I also admit liking them better in fron...

HiSomething sounds very wrong - maybe something fishy about your samples?Take a look at Nelson Pass measurements towards the end of the following document:http://www.passdiy.com/pdf/KleinHorn2.pdfwhere it looks like the PTR9s have similar sensitivity...

Sorry to keep returning like this. Thought I;d mention a tweet that unexpectedly impressed me favourably -- the Murata ESTD01 (these are their "serious" tweets -- not the "audiophile" tweets). Nice. Directly connected, enters strong at ~14kHz, by its...

I have listened to some expensive speakers from B&W, Wilson Audio, Dynaudio, and also owned the SF Amati, you know already. Musically these ones were more musically interesting to me than any of the others, but still weren't something that comple...
|

LOTs of time pretty much wasted lately, looking at "HE" direct-radiator drivers that are actually only HE at their uppermost frequencies, with diving responses and large-to-huge power "ratings" that allow the "pros" to simply turn up the heat to...

hello kids, a few weeks ago i started my hunt for a pair of speakers....i've been attached to my big system with a pair of headphones for the past year and feel its time to get some speakers to listen to music with (plus, i think my ears are now...
|
|
Nice post Romy, you're probably right, I can't say since I've never listened to a pair of speakers that really told me "what can be done". I've always owned and listened to speakers that are commercially made, and I've had to choose among the ones th...

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...

Lots of good information in there, if one has some idea of what it means in terms of sound and how it might be integrated into a system. However, some of the guys who are the smartest with respect to circuit design seem to have n...

Hi Romy ,well I appreciate the reply anyway! I have been reading your many threads and yes some on the Lowther designs but as you know your writings are a large large volume also and I havent made my way thru them all yet. As far as my room I could b...

Yes,I then did understand why you went into Bert and business and connection with sound (it works well as a general example). I don't know how you came to that conclusion of Bert fits into this model though. I didn't-- aft...

Thanks The CatI'm posting the pics of the build as I progress so people can see and pass on ideas, that's all. Are you suggesting you don't want horn projects shown on your site? I had earlier outlined the design, including cross-over points etc.I as...
