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 high and 125kg's compl...

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

[quote user="jessie.dazzle"] Are you suggesting : 1) Running the upper bass horn from a second ML2 ? 2) Running the lower bass enclosures (sealed boxes) from a second ML2 ? 3) Running both the upper bass horn and lower bass enclosures (sealed boxes) ...

[quote user="Jorge"]Actually a Tapped Horn would be bigger than a sealed enclosure, here is one of my first TH tests. The sound is very different than the sound coming form a Sealed encolsure. My first impression was that the bass was gone! There...

Quotes from Romy in blue :"...If you are not in very large room and your bass section are not 90dB sensitive then take one of yours left ML2.0, bring it to right channel and drive with it the right’s channel bass system instead of M1.1. It will ...

In the linked there above “Barn Conversion - James' Project” I have expressed my attitude toward low frequency bass. I certainly not “against” bass horn it but have “concerns”. The “open bottom” concept that I invented for myself is always make me to...

Re-reading, I realise you stated your preference for a sealed bass array only in relation to Dreyer's bass horn, not to bass horns in general....

[quote user="Romy the Cat"]
Tube traps are mistakably designed as they tend to deal with a very erroneous assertion that it is possible to feel a listening room with some kind of confused and random bass and then to correct the things with...

I think we are all agreed that if time alignment and space were not issues, a bass horn would be the way to go.Now, I'm fairly convinced that the overwhelming benefit of horns in this range is the phase response, ie flat group delay vs frequency. Mos...

Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...

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...

[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="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...

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 ...

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...

I heard the new or at least new to me Accapellas in the Marriott, ( the DeLuxe show which is a spin off) I thought they were pretty good, plasma tweeter,cone driver and mid horn and a passive bass which was sealed?I think they used to use active bass...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

[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...

Romy, at some point you did mention lowering current and shortly thereafter, if not in the same post, you added something to the effect of raising voltage. You even mentioned values you have tried, and I printed it out. But since I am usu...

I am playing with the tube traps and at this point I have a dual feeling about them. They are absolutely phenomenal HF absorbents, in fact much more powerful than any other tools I have heard. They suck HF from the room with a force of a good co...

[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.

[quote user="Romy the Cat"]Not kidding?! :-)Yes, I always felt that Tannoy the vintage 10" sealed box were the best Tannoy out there. Still they were the best not because they were best but because the 10” had less bass extension and did not go into ...

I've been thinking abut this question form several angles. Firstly practical.I thought I'd better see what low bass sounds like. And to get some idea of placement possibilities. So I set up my LS3/5as in the (rather cold) un-converted barn. Couldn't ...

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

[quote user="msaudio"]Your Typical Acoustical Suspension-type Loudspeaker enclosure witch has less then 90 db at 1 watt does not belong with a horn system that starts at 110db at 1 watt, even when you ad more then 1 driver, it is still way to far...
