Gday was thinking about buying these for a mid bass horn or may be a bass horn one day. There in terrible condition other then I think they have two real vitavox cones in them even though one has been replaced. Note the crack also. But t...

Gentlemen:I assure you, Infinite Baffle bass simply has no peer. Yes, you do need specialized drivers. The Infinite baffle bass concept is so old, it's rarely even considered anymore, plus, you are indeed married to the installation....

Here is another one, quite serious... only this one is 109 dB efficient.http://www.danleysoundlabs.com/pdf/TH%20221%20spec%20sheet.pdfThink about this for a minute...Sure, those motors will still need some current, but you might be able to rev 'em up...

Unicon, yes, this subject will be very much continue when I am ready and have some actual data in my head. The good news is that I learn that ASC goes custom work, I did not know it. I just afraid that ASC is a large company and they would make me to...

[quote user="cv"]I wonder if it is the reactive components (blocking caps etc) that are to blame here, seeing as much of the problem is in the lower bass.[/quote]Chris, what you said made me to think.
Look, the output of Bidat and a SS buffer that b...

Hey, Guys, I have a question to ask. Are any in existence 10" paper-cone drivers with free air resonant frequency around 20Hz and sensitivity over 95dB-96dB? The caT ...

This post is the phono-relevant part of info carried over from my recent "better tubes" post in the ML2 thread.Subsequent listening has established that the electricity during that session was better than I'd thought at the time (dammit!). ...

Bass arrays are considered infinite when they cover min. 70% of the room height. It is also important that they are mirrored (ceiling perpendicular to the array). Your new room is not ideal for bass arrays.I don't know whether you have read this pape...

Zanon, at this point I do not think about specific of amplification. I more care about the transducer per location ratio and a filtration in context of it in order to get the “filling schema” of the room properly. The quality of the powerful amp will...

Mani,
I would leave the subject of DSET/horn setup for another thread and would drop a few words about Zu Druids. They are not the speakers that I would ordinary comment but since I have a local guy with Zu Druids and I had a chance to hear th...

Haralanov,

[quote user="Paul S"] I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the ...

Adrian, I will be disappointed if the mixed-metal IC sounds just like the silver-coated copper I've heard, which pretty much lacked the best attributes of either metal and, further, its sound deteriorated badly, in short order.My own s...

Simply beyond any criticism. The Purepower bass was something that sold me on the very first unit in June 2007. The very first Purepower 1050 had the same type of bass. What kind bass? Well, if juts did not “improve” it and did not modified it ...

[quote user="Romy the Cat"]I did not have any low-power DHT but now what I do and when I drive 93dB sensitive speaker with it I have the very same ugly midbass that I experienced with countless setups of other people. I think it is a pattern. Also, r...

In my case, the Wright Sound WPA3.5s, with ~8 Watts on tap in A2, could not handle my 97 dB speakers; not because it was not loud enough, but because the distortion was too much of a factor too much of the time, and "bass" was bass-ically A...

I seem to remember that we've covered somewhere the sonic benefits of SET at lower frequencies, but I guess I never really thought of ULF as "bass", per se. If someone ever comes up with an SET that can be an effective part of an AuraSound circuit, ...

Today, I decided to measure input voltages that induce clipping in my operational DSET. I basically just put in place the appropriate load resistor, set the signal generator at a level in the middle of the bandpass and increased voltage until the si...

Further looking at where I would like to take the new 6-chennal version of the Super Milq I am contemplating a new revision of my bass channel output transformer. Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that b...

[quote user="Romy the Cat"] Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that begin to roll somewhere around 800Hz. The transformer ha s a lot of core mass and at full Melquiades’ LF power (~20W) it begins to clip ...

So, I have finally started testing a single Bass Cannon in my room.First, I had to get the rigidity as high as possible and then damp the steel ringing as much as feasible. I used butyl rubber/aluminium automotive deadener on the inside of the tube ...

"Best bass" is of course a matter of opinion based on experience and expectations. The (original) Hartsfield LF driver is certainly "designed for horn loading", like the Vitavox AK-151, whereas the AK-150 and the JBL D-130 are designed to be direct r...
