Jarek, can we just stop talking about the Dannoy "output" at 20 Hz, just because that's Fs? Not saying the Tannoy doesn't benefit sonically from its Dannoy configuration; but, if to add LF, as you say you want to, then you need subs, since the Tannoy...

[quote user="Vasyachkin"]has anybody tried a horn speaker with a dipole bass section ?[/quote]Well, I must say that I have tried dipole bass in a few configurations, including dipole bass plus horn, however I think this is completely immaterial to th...

[quote user="kodomo"]I am using sealed bass arrays of 3 per side. I have six 10" scanspeak woofers in total. I aim to operate them from 38hz to 160hz with qtc 0.707I also have a tapped horn that I am using with my current horn system. It is 244cm's h...

I am currently planning high-WAF speakers for my sister which have to stand in the corners on the floor. Asking for small corner horns I was told the EV Baronet could be a solution. Simulating it with roughly estimated dimensions I found that the FR ...

[quote user="Joe Roberts"] The L-9 enclosures were wood on all sides. Sealed box. No ambiguity here.Wings were common on theater speakers for mid-bass reinforcement. Plainly audible improvement on these and, for example, A-7/A-5 VOTs. It is equivalen...

Too late now for points, but just the other day I tried to imagine your plan. and I was pretty close.Actually, it is a bit like what I have going now; 15" Eminence bass guitarr woofers in a sealed 3 cu ft cabinet,Oris 150 with 8" B&C midrange dr...

Ronnie,
The stuffing the back chamber in upper bass horn and stuffing a sealed enclosure have totally different purposes. In the firs case we need to decrease volume of the chamber in the second to increase it. The polyurethane foam spray is not foa...

I recently had a visit by a close friend, who is an accomplished modern jazz saxophonist but a recording/mixing engineer, running his own small studio. We listened to some bass-heavy material on my Dannoys, the bass was acoustic - piano and drums. Da...

I've meant for some time to add a few shots of the ULF channels. Here's the first one; the photos were taken at my old place.Sized to fit through the door of the elevator (barely).Baffle and lid cut with diamond blade.Getting that lid up to seal the ...

[quote user="Romy the Cat"]What however is very practicable is some kind of sealed TT mat of 2-3 cm tall, fully filed with mercury. It would be 10kG of inertial mass – it might work… The question is how?[/quote]Ah, this is a GOOD idea! Wood would be ...

[quote user="Paul S"]Scott, is it your specific aim to configure an enclosure to "effectively" lower driver Fs? While this, along with an exponential increase in power, is a proven strategy for generating ULF, it seems like this approach creates more...

[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....

I would like to think a little about the monitors. A monitor is kind of bogus name but useful. I usually call a loudspeaker that is not floor standing as a monitor. Sometime they called bookshelf but I hardly image any loudspeaker on a bookshelf…

Maybe you remember, even though I liked sealed enclosures I chose the ported bass boxes for my system. The reason was the TAD 1601b's in my situation. They just work and sound better with ported enclosures as they were designed to be used that way.Ma...

These are 103db efficient 15" midbass boxes. It's a band pass horn design with narrow bandwidth of 60-250hz. No port thought, it's a sealed box with two chambers in front of the driver. I do not know how they sound but, myself interested in trying th...

[quote]Xandcg, I did not see this thread below. I would not comment
on 5x10x14 vs. 4x8x12 rooms, the answer is obvious,
What I will comment that the scenario you propose is very close to ultimate configuration
for Macondo-like acoustic system. A f...

[quote user="jessie.dazzle"] You might be able to get away with a bit less; if I remember correctly, my calculations at the time (based on the above driver) yielded a theoretical ideal volume of something like 23 cubic feet (sealed), so still not...

[quote]I do not know certainly
how the Western Electric L-9 was made but I think it is not sealed
enclosures. Some of the drivers of the period used the semi-transparent
cloth enclosures that you, Joe, might recognized as sealed.[/quote]The L-9...

[quote user="Lbjefferies7"] Now, as for your drawing of the exaggerated port flaires, it is excessive. A port is not a horn and, from an engineering standpoint, I treat them very differently. A port is a resonator. [/quote]
Oh, sur...

This thread is a derivation of the thread: Wilsons, EMM, Ozawa, Saint-Saens and...[quote user="clarkjohnsen"]While in general I agree with Romy about Wilsons, I have once or twice heard them sound really, really good. On the other hand I have also he...

Alex,I tend to aim for Q's around 0.5-0.6 for my sealed boxes, but thats only because I prefer my listening in smaller nearfield rooms. If you have a much larger room, you *might* be able to get away with something closer to 1.the 18W works fin...

Actually is not mystery but juts economics. BTW, the large Wilsons are I believe are not juts ported but so called fourth order design. With a sealed enclosure of the identical size the Grand Slam / Alexandria would go in Stereophile category of spea...

Just how important are subharmonics and undertones in audio, and how they affect tone? I played around for a while with the Townshend supertweeters, this is a ribbon tweeter that you can barely listen to: you plug it in and put it next to your...

Matt, if you have the Tristan with Birgit Nilsson and Christa Ludwig from Bayreuther 1966 then you might be all set. I am not a Wagner expert but the friend of my who is Wagner-infatuated gave me that brand new sealed 5LPs album and I am “working” on...

[quote user="Romy the Cat"]I, looking at my “7 reasons” do have a preference to sealed boxes. I do not believe in accuracy of bass horns, particularly in context of system integration.[/quote]What made you change your mind?...

Interesting. with sealed 280 sq feet and 8 drivers per side along a long wall you very much migh be able to use a singe 6C33C. With proper loading, good trasformer, DSET and these drivers you should be able to get bass that I doubt you will be able t...

[quote user="Scott L"]I had to take
pause before I answered here; realizing in an almost shocking manner [that] I
