Romy, I picked up a pair of FX120 and F120A drivers over two years ago. I initially spent some time with the FX120 in a small 10-liter ported enclosure (similar to Fostex' recommended one but altered dimensions). After many months of liste...

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)...

[quote user="Paul S"]For the Reps I will use a 2,200 Hz notch filter for its peak[/quote]Paul, why don’t you try to fix the problem of the Reps driver instead of notching it? There is a reason for the peak and I do not consider the problem could be s...

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...

[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...

Dominik, in terms of technology advancement, it seems their new driver is better than their other models. But despite this, I’m not sure their transducer engineer knows how to make the drivers to be valuable in terms of sound/tone. I’m saying that n...

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 ...

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...

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...

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 ...

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...

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...

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 ...

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 ...

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...

"the SG-570BL with S-150 horn mid-low isn't good between 100 or 150 (the horn name;-))"Why will it expect to be good at that range?? The S-150 horn has cutoff frequency of 150Hz. The suggested crossover point is 200Hz from GOTO.There is no doubt th...

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...

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...

would be finding midbass and midrange drivers with a similar character which allowed a good integration between them. Once I knew the drivers I might desing the horn (glubs, not so easy) and ask a skilled professional to build it for me, not impossib...
