Sometimes it works
Here is a guy undertook the Klipsh corner-loading project
http://myjubs.com/ With whole cons and pros of the corner-loading method in this situation is it possible IN SOME CASES to get VERY interesting bass. Unfortunately t...

Novygera:If you have a transformer where the impedance primary-to-secondary is 5K:8, it means the turns ratio is (5000/8)½ = 625½ = 25. This is the ratio by which the voltage is stepped down and the current stepped up in going from the tube to the s...

actually this is not so much about horn loading ribbons as it is about curving them, but also horn loading. look at this horn: http://www.pioneerelectronics.com/pio/pe/images/portal/cit_3442/35960TH-4003_s.jpgnow imagine a ribbon of approximately sam...

I see, this tri-way Quad system for sure shall be much different from regular Quas. I kind of even understand why you stay with open baffle bas to support the system’s bass. For sure it will not Bruckner-style pressurize a room as non-dipole bass wou...

[quote user="Morfeas"] Fs of the driver is measured at 32HZ matched for both channels. [/quote] Manolis, if you have 32HZ of loaded driver resonance and a large throat in such a short horn then I would propose that you have your 50HZ not from the loa...

Scott, you have to find another way to post the pictures, the site has multiple options to do so but you still insist to load a binary sting – sorry it does not work. It would be nice to see the idea behind the Dean bass horn and your sketch how you...

I must say I've never came in to intimate contact with cables and avoid it untill I can, so yes all my arguments are theoretical.By amplifying I ment of course voltage, not power and ass-u-med that the external noise as well as the cable distortion a...

Paul,I agree 100%. Well sort of.....Can the idea of the overengineered, atomic reactor power supply with water cooling really offer someone just interested in great music a "better" solution?I think for many, the technical superiority is at least as ...

Hmmm. I need to admit that I did not read the article above and I did not familiar myself with the author’s reasons as I stubbornly consider Fremer to be an idiot. However, purely hypothetically thinking on the subject I wonder why the presence of mi...

Antonio, I never understood this concept of “gain selector”. If I remember correctly S&B had 10, 20 25 db options via re-wiring of the primary coil. It is not complicated to place primary in some kind of rotary 3-position switch but it would be c...

OK, this is useful also, in that you have not noted a "pattern" as you say. My point is closer to your suggestion, that I do change cart --- and sometimes buy new ones, B U T I do not buy other SUT (at least I try to avoid it). I'm currently waiting...

[quote user="drdna"] How about using the 6C33C for the low midrange-woofer, the 2A3 for the upper midrange, and the 45 for the tweeter? I suspect if each circuit can be optimized, that they can do their best within each frequency range. [/quote] Hm…....

[quote user="drdna"]
I chose this for a sound most free from "graininess" which may change with PP2000. However, what is the rationale to change the impedence loading on the tube, from your perspective? As you know the Magnequest OPT has taps for 4,...

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"]The biggest problem that usually people face when they listen the middbas horn is that people tend to make the middbas horns too short. In the short horn the driver shot right through the horn and the LF go not “get loaded”...

[quote user="Vasyachkin"] i will give you this much - horn loading ribbons is fundamentally not as advantageous as horn loading dynamic drivers. this is because ribbon mass is already close to airload mass (in theory could even be less) and little ex...

[quote user="Dresden"]I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.

As some of you know I’m playing last couple days with Red 10” Tannoys from 60s. My selection of 10” was not accidental -I would like to get as less as possible of that “Tannoy bass” but I did run very far the “Reds” turned out to have 27Hz open...

[quote user="Romy the Cat"]...it is difficult to design an objectionably performing powerful full-range SET without considering speaker, particularly the moment of LF section damping. It is not always the case the MF, HF and LF would require the same...

Ronnie,
Arranging the driver in a line array is a fierily straight forward thing. Also be advised that the arrays will less likely work across a short wall, and you need to use a long wall. Generally it is imposable to advise anything as any rooms a...

I keep thinking about the type of the loading the guy from Germany
used. I am not sure if I agree with Josh that the absence of front chamber if
the key for the success that Josh describes. Let analyze it.
The front chamber for LF drivers is not...

Delet if not proper topic. Was wanting to experiment with 6e5p driving lifeless speakers. with possible 100v swing i'm guessing way to much for regular garbage amps. What are peoples ideas for lowering output v (to like >5v?) with out destroying...

Wow, I mean really, really, really, really, really WOW!
A week ago I converted one of the Super Milqs to 5:1 loading and yesterday I converted another one. I loved what the last week converted amp did. It was very nice but today I put the entire sys...

I do not want go for emergency ULF amps and to pay more than $50 for it, in fact all plate amps shall cost $50. I will probably end up getting another B2 amp, identical to the one that blew up with the identical changes. I just felt that this no-ampl...
