[quote user="el`Ol"]Maybe one should't give up the attic-IB idea, the subs could fire downwards.http://www.aespeakers.com/drivers.php?driver_id=8[/quote] Great idea, thanks for reminding. That still might be an option. I need to educate myself about...

But efficient (in terms of space usage) and radical.put woofers in the sides of flare of your attic horns, sort of like Danley Synergy horn, not near the throat but towards the mouth area, using the attic as the infinite baffle.But will the pressuriz...

Romy,If you havent already, why not explore the Infinite baffle concept? Or a long terminated back chamber for that matter.Current drive should also be very good on the lower registers.Rgds, Collin...

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...

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.
They...

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. ...

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...

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...

Scott, I tend to think of IB in simple terms, basically, literally, as an "infinite baffle", the idea being that there is no load other than "open air" on either side of the driver diaphragm, and there is no "baffle step"/acoustic short between the t...

It looks to me that I will be able to live with my 6 driver
line array. Again no measurements were made but it is what it “looks”. Sound-wise it is very reputable and I just might
leave it as is. My current room is 6 larger to what I had in downto...

Decoud,
There is nothing wrong in what those guys propose and there is nothing wrong in in-wall to mount drivers in infinite baffle configuration. In fact it very much interesting idea to build a custom room with a strange shape where wall most favo...

Thanks, Guy. JC Morrison? I am not familiar with this character well. All that I know about him the he pop up usually around Joe Roberts and they perfume act of public saliva liking. It does not say anything about his amps, however, neither about his...

Thanks, Jorge, but what you propose and what is done at the pictures your posted has nothing to do with Infinite baffle. This configuration rather reminds me the 4th order bandpass. It is popular setting but it is not what I like as the bass coming f...

I think that the discussion of extending response (especially LF) is the WRONG direction. We know that the Macondo/Melquiades setup had more extension and integration than is even possible with Dunnoys. I am not sure why this is even getting so many ...

[quote user="Kerry Brown"] Yesterday a friend of mine brought over a CLIO analyzer and we graphed the impedance vs. frequency. I was surprised that the subhorn measures like a ported box tuned to 50 Hz ! [/quote]Yes, this all is very explainable. The...

As much as the concept of MiniMe I find is supremely useful as much it was unlucky in my implementation. I went over a number of monitors, then built my own versions of MiniMe, then in the new room I used Danlavy SCIII. Some of them were good but it ...

Vincent Brient is French guy who has built an interesting installation that I think worth to analyze. Years back Vincent was an enthusiast, like normal people, but it looks recently he turned “pro” and came to audio market with his own version of...

I set up today the framework in which I will be testing my Vitavox 15 inchers. It is a wooden frame from my bathtub with a driver screws to it, the massive sliding doors that squash the driver from both sides and cardboard that cover the wholes. This...

Gentlemen:I've thought about this mid-bass challenge for quite some time. I have tried many approaches.For the sake of my example, let's assume mid-bass to cover from 60-600Hz. That just happens to be the classic "decade". I have to fully agree with ...

Thanks for your further thoughts and explanations Robert, Romy and others.It looks like the full room enlargement will be my choise. Dont know i want to block the windows though. Maybe i can solve this by making a glass window behind the screen.. I w...

[quote user="Edgar="]Not Amplitude. It's the rock solid phase linearity. It feels like a brick wall all the way up and down. I haven't looked at any graphs and haven't measured anything but that is my guess. There is no question of the great tone of ...

[quote user="Romy the Cat"]...but I was wondering how the length of the port and the most important the proximity of it to boundary affects sound. [/quote]A general rule is to keep the end of the port at least twice its diameter away from walls....

Actually it is very possible that it might be so. I made some rudimental measurements and concluded that RAAL tweeter and JBL midrange mounted in the same baffle has non-perfect time aliment. So, I will need to use gaskets under the drivers to time-a...

Romy:Thank you for your response. You are correct that the vision is not completely developed for this 4 way. A bit more info is needed. I've had some experience with JBL woofers, but am relying heavily on the results achieved...

[quote user="Romy the Cat"]Guys, I am not looking or care about the design specifics but rather looking for some fresh idea and inspirations that would make me to think further. You see, if I shut down Macondo and measure just ULF channels then I...
