I recently spoke with Paul Eizik regarding the criticality of the open-air mounting of that driver instead of baffle-mounting. I decided to go extreme and to get rid of that plate that I had under the driver no mater now small it was, also I thought ...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

I don't want to get off on a tangent here, but I have been using a sort of MF injection by default for some time due to OB backwash from my DX4s between 150 and 2,400 Hz, since I leave the back of the driver open. Yes, this is "out of pha...

[quote user="guy sergeant"] The bass system had the two pairs of drivers facing each other into a 12" wide 6ft tall 'slot'. The drivers were open to the rear. I think this had been put together just prior to the show.[/quote] Ah, the slot-loaded, fac...

I was trying the drivers in my infinite baffle parody configuration and I have to admit that that all of them sounded not good. There is not even a fraction of tone that am loosing and from any other quantifiable subjective point of view the driver d...

When i Moved in my new house in july 2000, it took me 6 months to get my speakers and general system togeather and working. The narrow band that your vitavox 15 inchers will be working in, how does that relate to your infinite baffle? 60Hz to 350Hz i...

Since no driver is actually full range, driver selection is partly conditioned by how well it plays with the other drivers it will be used with, and - very certainly - the crossovers it will be used with, also baffle shape(s) and size(s), amps(s), an...

Hi Romy. I recently saw a thread which may have been posted some time back to do with using a reflexbox for mid or upper base. My impression is that you are solidly opposed to using this setup within the rangein which it is normally used but in the...

The hardest part of making the cork gaskets would be making a decent template. After that, it's just rote labor.You might also want to mess with whatever you are using to fasten the drivers to the baffle. These fsteners should probably al...

[quote user="Scott L"]I had to take
pause before I answered here; realizing in an almost shocking manner [that] I
don't listen to many commercial loudspeakers.
I am largely involved in the (gasp) DIY
community, where it's also very often done inc...

IMHO one of these drivers that make you listen to the music at first, but something isn't quite "right". Put it on a - big - open baffle and cut at 200 and use maybe up to 2500Hz. Problematic with female voices, like opera and so on. It distorts quit...

Congratulations, Romy, I think you just re-invented the ISOBARIK loudspeaker.
Although, Linn's Isobarik implementation of two drivers moving in parallel separated in a small chamber which would be nearly in constant volume (and pressure) couldn...

Hi Romy,Great site!!!!I`m in the early stages of designing a horn system and have been unable to find any info on thesubject of boxing in horns leaving only the mouths exposed. Is there anything about doing thisthat would cause degredation in th...

Hi Kitty,This combo is quite interesting and amazingly coincidental....I had scan speak 18W's sitting around from my old speakers and just recently had them put in sealed boxes. I was using a Seas silk dome on top (in free a...

[quote user="Paul

I think if such a woofer “ignites”
shaking within the attic then all bets are off and it need to be avoided by all
cost. To do “right” thing I would put pneumatic decompiled be...

Not to leave Bill hanging, Romy, but were you not curious enough to take your original Dannoys home again, to at least determine as a baseline tenet that it is repeatable? If it is, then you can more closely replicate the original cabinet/set-up, and...

The best-sounding drivers I've heard will amplify a wide range of sounds from scratching or tapping differently at different points on the cone, or even from tapping or rubbing the driver frame. And never mind OB, some throw amazing tonal range and ...
|

Paul, as this sensation also happens during performances without "bass pressure" (a solo lute or voice for instance), I am not even sure how to start looking. There is a part of real sound transmitted not processed by the ears, rather over the skin. ...

[quote user="Romy the Cat"]Here is pretty much the idea that I had – a very tall line array with min footprint and with more of less corrected timing error by angling the front baffle. At the picture below the curvature of positioning of Macondo chan...

I do not exactly understand what you are proposing at DiyAudio site. I have generally an attitude against dipole radiation, and particularly in bass. There is a common believe among audio people that dipole bass has advances, there was a lot of said ...

I was strategizing how will be putting my audio crap in my new listening room. The room is being remodeled now and here is an interesting subject. The room has 4 wall-installed loudspeakers mounted on the cathedral ceiling.

Very nice mounting. Hopefully the ridgidity will not cause any other unwanted vibrations from moving the assembly ever so slightly. I doubt it could be heard if so. Having used the T-350 (and t-35) over quite a long period from the mid 70's through t...

I went today to La Pergola web site and saw their “review” of Blumenhofer Acoustics loudspeakers.

Forgot to elaborate the Quad system.It is actually a tri-amp Quad system, below 100Hz is the Supravox 15in Field coil in open baffle, then it's a Stacked Quad ,and about 5Khz there were 5 RTR ESL cell. I did try the 6C33C amp in a single pair Quad by...
|
|
Romy, I suspect that 200 Hz high-pass will be too low for that driver, even 2nd order, and almost certainly with just 6 dB roll-off. I think more like 500 Hz with 1st order, and might still require the coil.Yellow-type drivers take on and ...

This weekend if I have time I will be doing the testing of my driver deciding which one I will be using. The framework of testing will be the following: a single driver, closed at 150Hz first order, mounted in infinite baffle and working along with M...

Looking at the better photos, with a rear view of the LF speaker, the "felt-covered large port" is actually not the worst possibility (a quasi "IB"), depending on some things we can't see and how well that driver "likes" it. I can also see that what...

Hard to comment on this one... Seems like most everyone I talked to there hears with their eyes, and thought they were beautiful sculpture, therefore sounded wonderful... Maybe I should just be honest and say I flat didn't like the s...
