Sorry Robert, Your opening line on "Good luck getting midrange from F120A for non annoying monitors." tended to set the mood for the rest of your post in a negative light for Fostex drivers, the F120A included (at least for me it did)...

I have seen those old Telefunken, Siemens and some other 4” cone direct radiation tweeters, but I never tried them. I do not know thier signature and I do not know thier characteristics. The reason why I never cared about them, although I might be wr...

Ok, I blamed the tweeters and MF drivers now the turn of the MF horns. The Mid Frequency Horns (I’ll them “MFH” from now and on) are the stinky like pieces of horn installations, and if they are not done correct then they screw up anything big time T...

Romy,Point taken on the Ozone issue...do the catalytic converters in the units work effectively? I do not know. There are relatively inexpensive measuring devices for it.I agree completely that they sound different. You can see in my language that I ...

Hi Romy,
FYI: The previous photo of some unknown persons "pile o' horns" appears to be:
Upper midrange: 1" TAD TD-2002 mounted to 650Hz Edgarhorn
Supertweeter: Fostex T90A or T925A.
Lower midrange: ...

Hi Guys,An idea I've had for damping thinner horns in a more or less aesthetically pleasing manner is to house the horn in a Sonotube rigid cardboard cylindrical concrete former, and then apply the desired damping material inside the Sonotube.&n...

..... he he :-)Seriously, I listened some months ago to the LL1 sig. /ML3/Alexandria combination. A perfect example for an expensive mismatch. These Wilson Speakers are a grave for those amps, midrange is ok, but no high frequency area and absolutely...

[quote user="zanon"]Romy:I was not aware that manufacturers of multidriver system let you attenuate individual drivers. I guess if you multi-amp, then you have control at that level. I have never encountered such a system so I cannot say, but if it i...

Folks,Before we discuss "high distortion" amplifiers, lets us ask what kind of SPL Romy's system produces.I don't know, so let me make some eduacated, conservative guesses.Let us assume his midrange and treble Systems are both 100db/W/m and he listen...

well i never thought i would be opening such a pandora's box with this combination.firstly,the drivers have the plastic surrounds(whew,lucky!i know the diaphragms are potentially harder to source than the drivers)what indicators or criteria would mak...

For my ears, the piano is rich in harmonics that change with playing volume BUT the only way to get a louder note is with the hammer striking the strings more powerfully which always is coupled to a louder "articulation". Violins and wind instruments...

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 ...

Yes, I do believe your exact crossover points would be irrelevant as well. I just wanted to know the span of your horns and drivers. I especially wondered about your fundamentals channel. You said it was narrow but what is narrow for you. Mine covers...

Romy, thank you for your thoughts. First off, my further thought on the system and specifically the implementation of the high freq section: Yes, the time alignment would be a challenge but possible. This is the main compromise, in my view but the le...

I was there and heard it a while and then came back the next day to see if what I heard was true... it was.I talked with Allen Sides who was there showing his speakers and having a good time. It is a 3 way speaker, It has a 1" JBL compression driver...

[quote user="Romy the Cat"]In contrary, at higher frequencies dipole might work fine, but no in bass. The Cat[/quote]
IMO you can never get realistic imaging from dipole.Here is a very detailed description of a dipole horn for the BG Neo 3.http://ww...

There might be 'rule of thumb' here, but let me explain a bit better with some specifics.I'll have a Radian CD in a 425hz horn playing 800hz up to where it starts to roll off naturally at 6db at, say, 10K. And a similar Radian taking over from there ...

I think I wrote In the past here, if you like the 10” Tannoy, why not try the 12” or 15”? The ones with rubber surround are not so good in my view (from CPA or DMT series as they have very restricted midrange) but the cloth surround Tannoys are wort...

[quote user="Gregm"] It's better than a Marten Supreme because the mid is cut off @500Hz whereas Marten cuts it off at 1,3kHz "where the ear is at its most sensitive". Note: they must be referring to latest technology ears -- not the tradi...

[quote user="Romy the Cat"]I personally tend to use TT with heavy platters and I feel that if a platter is substantially heavy then there is no different how you would drive the platter. Put a platter of 100kG then you will never recognize HOW the pl...

Thanks Romy, very interesting thread.I've never tried the analogue inputs for the DEQ2496. If I want analogue in (which is rarely) I use a mytek a/d which sounds quite nice (but oneday when I get the time I'm going to modify it with i/p transformers ...

I am not quite sure what is going on but wherever is going on is wrong. I was listening this morning Shostakovich’s second cello concerto by Berlin and Rostropovich and I detected that something was not right. It was too direct and “too stereo”, if I...

Well, never say never and what I said that the Injection Channel is done it meant that it WAS done. I am experimenting now with other way of use Red injection. The application as is at the picture practically had no impact to imaging. However, I need...

[quote user="Tax"]The other options are to get some custom Amorphous OPT's <50R 350mA 8:1 as per previous posts, or to possibly pair Romy's LF tributes (for sale section) with a pair of Lundahl's in a two channel DSET configuration. The Avantgarde...

[quote user="skushino"]Have you considered the opportunity of raising your upper bass HP crossover? How high do you plan to use your mid bass horns? If your mid bass is comfortable playing up to 280hz (or whatever the right freq is), you can use yo...

Dear Romy,
Thank you for the commentary and the advice with regards to the need to have a COGNITIVE ORDER OF SUCCESSION and to test with another speaker in situ first.
Given the varying degrees of how different individuals process COGNITI...

This is left channel. Right channel is mirror image.I am using 6db active crossovers all around.The subs are pair of 18" Aurasound 1808 per side. The current midbass is the white color horn you see. It is Funktion One DS15. The issue with this one i...

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...
