RomyIt's topical to ask, since I'm building a 4-way system at the moment ..( Tapped horn behind and three-way horn system in front )Do you favour the tweeter horn to be placed at the top, above the mid/HF horn , or in this situation place the tweeter...

Romy, as you know by now, most small generators are toys, really not suitable for our purposes. I have no idea where or how you found the perfect old small generator, but starting with what you have, if you can get all the wiring right, you just mig...

Hi,I thought on tetrodo (KT-88, KT-120, KT150) and write pentodo, sorry. Wherever the tetrodo sound were nothing special I personally find them a lot of better than solid state, that why I was asking, and these days one can have 300W with to KT150 P...

I use hypex amp on my tapped horn (so ULF) and it is great. I use a plate version specifically built for sub duties. It has a 18db filter as well as a rotary phase knob which comes in handy! I have had no problems, and can not say its doing anything ...

There's a big difference in 40 - 400 and 90 - 400 Hz. 40 - 400 might also be stretching the bandwidth which will be horn loaded? (FLHs by nature are narrow band, 40 - 400 is over three octaves...) And, besides the coloration Romy mentione...

Hi, Marcus
As I understand it is 15” loaded into 110-150Hz horn, MF compression driver in 350-400Hz horn, Ribbon tweeter and a pair of tapped horns? Looks good.
If it were up to me than I would paint the entire baffle with tweeter and MF i...

Here's a pic (link) of my listening position.When I built my large Bill Fitzmaurice bass horn...I had thought about placing it in that space above the speakers, firing into the corner. I may still do that...but the sub is serving duties in the separa...

ThanksFor some reason, I can't attach pics. I use the attach key, but when I post, nothing happens...sorry.Here's some pics on Stereonet (in Australia) with my build pics.My comment re you cringing over Selenium, is that these are cheapish...nothing ...

Hello Romy, thank you for the answers. Your horns have a round mouth, but their profile is not spherical. That is the profile of the Avantgarde Horns you formely had - apparentyl you have anayzed them intensively, could you elaborate what problems yo...

Well, Tannoy tuned all their 10" monitors to play reasonably well down to about 50 Hz. Their monitors I heard were all variations of ported, with some of their "newer" monitors (70's?) using the ports to create more apparent bass, and those monitors ...

Hello,i made a few bass horns for home use:[url=http://www.abload.de/image.php?img=hm-moreart11pichrc5.jpg][img]http://www.abload.de/img/hm-moreart11pichrc5.jpg[/img][/url]a seat, writing table[url=http://www.abload.de/image.php?img=baufoto9eckh.7rgu...

Hi, it is a bit unclear what you mean.If it is what normaly is called a tapped coil it will be dead wrong and the results probably invalid since different parts of the coil volume in the iron structure would be without current, depending of the tapps...

Up to the first fold the horn is somewhat conical as seen in post #1 picture.This picture shows the exit w/ additional angle wall (making for "corner" loading).This has a greater (uncalculated) flare something like a compound CD horn.Resonant F unkno...

You are right Romy. When I toe them in a little more, that curve flattens. If I toe in and also sit about 10cm's higher, it is both flat and more extended...These will be very important as I will be designing the final stand this winter. I am so happ...

-Background- Enspired by Jeffery Jacksons system as displayed @ VSAC, I'm building a five-way horn system. Tapped horn for up to ~80Hz; w/ Eminence driver 65Hz Tractrix from ~80Hz to ~400Hz w/ fane 8"; 250Hz LeCleach from ~400Hz to ~2...

BR, I have never used Romy's amp design, but I have used 6C33C SETs with Lowthers. I do not use my Lowthers FR, for reasons that are fully explicated throughout this site, so I don't worry about LF from those drivers. IMO, their best is MF up to tr...
|
|
Fair Xmax, and that (plus multiple drivers) is pretty much necessary for a 10" driver to go low. The best thing about this LF idea, IMO, is that it increases your chances of blending sonically at X/O. No idea how the cones hold up with the power (inc...

Hi Romy,Many thanks: the answers are...1. The tweeter I thought could go below the MF.2. The room is 5m x 5m x 3.6m.3. Given size of room, corner location would be most practical.4. LF will have to be compact, hence tapped horn appeals.5. S2 diaphrag...

I like having a center-tapped filament winding for flexibility. First, you can use a traditional approach on hum balance (what you have now) or use a slightly different approach. I use the center-tap as a fixed DC balance (cathode bias resistor solo...

The pros and cons of batteries are fairly well known even in the captive audio press. I like the idea of digital conversion devices running off batteries. Field recording devices with ADCs and DACs can sound cleaner than those running off the grid. T...

[quote user="Jorge"]Hello Anthony,I did experiment with metal tubes for bass in a sealed configuration as you are planning. The weight of them, even made out of thinner than you would like steel, is prohibitive. If you make them out of aluminum pipe...

Hi,I dont use my tapped horns any longer because of the annoying peaks above the usable frequency range. Some how they managed to excite a room node at 60Hz that none of the other bass solutions I have tried messed with. They also didnt have the outp...
|

Well they are not my sound either...I've gone tractrix on upper mid and mid horns and exponential on mid bass. Still have the tapped horns.The now black horns are someone else's and are intended to be used in light / small scale PA. That's the idea a...

I have no idea what he is and what he is looking for. He declares himself as “just an average guy in an average basement shop building hi-fi audio horn speakers from wood”. I do not even know in what country his leaves, not that it is important...

Here are some real world measurements made at the 2007 NYC sub shoot out. The distortion numbers and characteristics should help us understand the difference between tapped horn distortion and conventional front loaded horn distortion.
The fir...

[quote user="anthony"]The large 42Hz horn would probably want to be crossed over from 160Hz-200Hz at the most which would leave the top octave of the horns range for attenuation. So what you really need is a horn from about 100Hz to go above it...no...

Since I last posted there has been some progress to my indoor and my outdoor systems. Indoors I have added a pair of tapped subs. I must say that I am quite happy with these. Of course they are not as good as full size front loaded horns but still a ...

LBJ, now that you ask, it's funny to say here that I first ran across both G-10 and Micarta for use as knife handles. I really dig the tactile qualities of these materials, especially G-10, and I thought my high-end customers might like them as...

Romy, You make all very good points. I probably shouldn't call the front of the driver a phasing plug, because actually the long wavelengths really don't care much about the shape of the exit, they will just pass right through...
