I think this is the one w/ the ribbon driver . Seems more innovative than contemporary Western Electric approach. That is the planar driver would not require a phase plug ?Western Electric's mid 1930's phase plug passes sound thru narrow slits and ot...

Once again, it is not about the loudspeakers but about the idiots who put themselves in position of shaping public opinion by expressing the “expert” view. Yes, I am taking about the Morons who write those audio reviews. A new Danish 90db sensi...

Continuing to harass the readers of my site and myself with the good news about the performance of my SA8535 driver I would like to post a very educational article about the subject. As I told before, being familiar with sound of ribbons then never i...

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...

I`ve had many small ribbons in my system over the years and I don`t like them. True, they are without competiton above a few Khz, but how to find a decent partnering midrange? They represent unnecessary fragmenting of the musical spectrum (a typical ...

Hi Romy,
Give the ribbons a try http://www.e-speakers.com/products/beengineering.html. These are too expensive I think but believe me the sensitivity is real. The best part is also that the impedance is very flat and an easy amplifier l...

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...

[quote user="Paul S"]By far the most promising planar speakers I've heard have been the giant Sound Lab models. These use an assortment of variously-sized "tuned" planes comprising one larger, "curved" plane. However, ...

I do have a speaker with a flat impedance. It is an Apogee Caliper Signature with an impedance variation from 3 to about 4.5 ohms over the whole range. Fortuneately it is not so dead as your example as it has about 86db sensitivity. ...

As I grow old and nurse a fragile back, I too have a fantasy of a good sounding, lightweight TT (and amp, speakers for the matter).Every lightweight TT on the market makes me interested for this reason
(Rega Planar 9, Well Tempered, Roksan, Amazon,...

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 ...

[quote user="morricab"]Hi Romy,I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty...

Hi. First time posting. I had long admired an older friend's RX-5000. He left it to me when he passed last year (RIP, Bill) and I recently got possession and did a lot of cleanup on a table that had been sitting for a couple of decades. He has ow...

[quote user="rowuk"]I have heard some nice speakers in Germany using the Mundorf Air Motion Transformers. No saliva, ample "substance" in their tone and a very nice integration.http://www.mundorf.com/AMTnews/MUNDORF_PRO_AMT_FLYER_2012.pdfhttp://www.e...

The main trouble I've had with any sort of wave guide - including horns - is their audible-to-me signature shaping of the sound, like speach. I just have a hard time shaking my awareness loose of the shaped sound as I try to listen to music thr...

Hi Paul,The Cogent diaphragm I have seen pictures of was woven carbon fiber with a leather outer surround. I have never listened to a Cogent 1428 but they must sound very good, at least Bill Woods and Bruce Edgar say so.Besides their overall ultra cl...

I'm wondering if part of this "glycerin" sound of ribbons is just "ribbon sound", or purely frequency dependent, or if it has to do with the size of a given ribbon at a given frequency. But why should ribbons not be subjected to the same demand...

Well, it looks like my lack of familiarity with ribbons/planar/isodynamic tweeters made an evil joke with me as the more SA8535 tweeter getting broken in the better it sounds. As now, after near 80 hours it practically free from any negative things t...

I would agree that the Lowther is not hard to beat but the question is where and in whose mind does this competition exist? Is the Lowther, Manger, or other full range single driver in competition with different multi-driver approaches, other single ...

Actually, when the string section has to play ultra softly, they use a mute or damper on the bridge. This is a device that limits the ability of the bridge to pass the string vibration to the resonant body of the instrument. http://www.youtube.com/wa...

I'm right there with you, temporarily installed in the middle of a Bagdad intersection.So, one day not too long ago I slipped out during lunch and picked up a pair of decent, closed-back, full-size, fairly antisocial looking headphones (ATH M-50s) an...

If I may add, from experience, following and including Romy's post above:1) In cases of established incompatibility with a average power SET, more output energy (55W), will not completely clear the above 2) and esp. make 3) less "muddy" or ...

I’m glad you talk about geometry, but to respond to this I have to refer to other brands. I will only talk about facts and hope it’s not offending anybody.My basic point is: the flare rate has to be coherent right from the entrance of phase plugs. In...

So-called omnidirectional sound (of course here we are talking only about 360 degrees within a two-dimesional plane) is framed in the concept of emulating the microphone. This makes no sense to me, since it, firstly , fails to emulate the microphone....
