Your rules say no direct answers so forgive me this one.
My horn is a true 21Hz horn.If you want to do the calcs:(More or less) Throat 6264 square cm.Mouth 48312 cmsq.M or Q 0.7 depth 3m.Quarter space loading.It does not quite make 21Hz.-3...

Romy, thanks for your thoughts,Quotes from Romy in blue : "...I personally do not feel that you use Fundamentals Channel properly. You desired to run your Fundamentals Channel up to 3200Hz but it is too high..."Maybe, probably, yes, OK, I a...

Very interesting. I appreciate that you have exposed more of your listening sensations - that give more objective information, letting to propose more accurately what might took place. In regard to what you say it might not be the “phase ...

All-I'm optimizing new speakers, but the deep subject matter is a little new to me. Will this work?Using a pair of Welborne Labs DRD300B SET amps (tapped 8ohms) with a 3-way passive crossover to integrate these drivers. Here is ...

There is an ancient Hebrew proverb saying that if you have problems and go sleep. Last night as I connected the new assembled Remedius it was so bad that I indeed went to sleep, hugely disappointed. Had an ugly dream, wake up and immediately see ...

Pierre, yes, I understand it. It kind or irrelevant what they destined for and yes, in domestic applications in context of low power we can use it lower. What I am saying is that as we do use it at extreme low range we deal with slightly overdamped d...

This mooring I decided to play with my infinite baffle. The
mess with my analog crossover hat was calibrate for my old listening room gave
me bad IB taste. I bought used stinky Behringer DCX2496 Ultradrive Pro crossover

A few things I would like to say in context of Pham’s playback.
I will leave his infatuation with turntables alone – man like to collect turntables and he within his constitutional right to do whatever makes him happy. The problem that I see ...

If the setup is semi acceptable, after ten years one should lose the evaluation part of listening experience and treat the system like a kitchen radio or car playback and simply enjoy the music. I think ten years is a minimum to achieve the position ...

[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...

I am observing an interesting and surprising fact – I am begging to like my active Marchand crossover. I did a number of modifications to it and it looks like the parts are broken-in now – it does sound very pleasant for my ULF. I feel it is a bit to...

This is my current 4-way GOTO setup. I know it is in no way optimal but I am interested to find ways I can improve it's layout.

It is not about “how low can the 600hz horn go before running in to problems” but rather a specific if of Vitavox S2 driver. The S2 with plastic suspension has secondary resonance at 1250 cycles (you might read about in details in my S2 thread). So...

Romy!Put on an engineer hat!
Time-aligned is an impossible task from my point of view. How can one perfectly time align different drivers? Align to what precision? mm, inch, cm or ft? 5%, 10%, 30% time align? Align to the tip of the cone or...

Romy,If you look behind the physical time alignment and start discussion about relative time alignment, that is a good start. Thing puzzle me about your view and comment of GOTO system setup that you have seen on pictures or web. How will you know ...

The more I think about it the more I realized that this 120dB per octave crossover is very interesting move. For sure it is bold move. There are unquestionable benefits of such a “barbaric” crossover as the throwing way bits at the signal get attenu...

Hello,I just logged myself in so first of all: Hi Everybody ;)Few days ago I aquired a pair of very interesting 3way horn speakers which seem, as I imagine, to ba an ambitious DIY project from the past. These are basically the Altec Vott A7 replicas ...

Mats, I do not know who is Jeffrey is, anyhow, your horns look nicer this time. You need to figure out now what would sound more interesting: the 8PS21 at its higher knee or the Altec at it’s lower knee. The important would be that beside thier absol...

Operating a driver in an open baffle will cause front-to-back sound wave cancellation, aka the acoustical short circuit. In addition to this, a plane board baffle offers zero air load to the drivers cone. This is not good. That's why it sounded like ...
|

Righto then, I guess there is no reason not to try this, except that one of the original crossovers here is non-functioning (if I remember correctly), so if trialling in stereo I'll have to crossover in Melquiades. Should have the parts here to do t...

Romy, what exactly was bad, and how?Honestly, my knowlwedge and objectives were in infancy back then. Also, it's been so long that my "memory" is probably crowded with parasitic ideas passing themselves off as memories. But I remember the 808 drive...

As the builder behind these horns, I can answer some of your questions. It's true, I was primarily focused on the woodworking/building side, and now I'm experimenting with amplification and crossovers. I can't speak authoritatively on those subjects...
