Hello Romy, thanks for your guide.I've been thinking and I feel that some basic upper bass channel ideas are forming; they a result of, as you say ,"organic" derivation from the rest of my acoustic system. I am pretty excited about this idea i have. ...

I know this is an oooold thread, but how about the Precision Devices PD.2150? It has good LF capabilities and is reasonably priced for such a huge driver. It even has a new neodymium sister (PDN.2151), if the weight is an issue (it is absolutely huge...

I understand that "nothing changed in the horn dimensions if you go from between 10" and 12" driver". You are referring to the horn mouth I assume. Do you have a idea what compression ratio is good to have for upper base horn? It seems that 2:1 is ta...

Hi Romy,Well, I do not pretend to "know" those Rare-Gas zeners very well, neither to have "listened" (so to speak) to any. They are so low-performance devices when compared to the silicon technology that it is technically a pity, but, it doesn't prev...

After living for a few years with Edgar 80Hz straight horns, I've had many urges to find a better sounding solution. I have a reason. Every time I turn them off and continue listening without them I notice that something good happens to the sound. It...

"It is not an accident that I liked the article about the “Resonating Oops” to this thread."Interesting. I'm just completing my 125hz midbass horns. And I'm deciding how to construct the back chamber. I think I will experiment with a removable and tu...

Very cool, James, it would be very interesting if you put your ears into an investigation of “Ooopsy back chamber.” I was wondering about the A45 Lowther as well. The 125Hz midbass horns that you made, how big the input hole in there? The attempt to ...

it seems even Thorsten do not believe computer source could be perfect and he just guide us to reach max from computer."
The computer is a great music server but also a source of jitter ...

Romy,Thank you again for a helpful reply. Your comments are very appreciated inspite of not suggesting what to do. I will figure that out myself. And here is what I've learned so far:>> Herman, if you use Precision Devices hen you are at mid-hi...

Petar,I thought for along time how to reply to your post. All my thoughts basically narrow down to this. You're a soulful guy. There is nothing smart I can say to add or subtract to you findings but I think that the result you will finally get from y...

[quote user="ulf"]One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

[quote user="noviygera"]My mid/upper horns play down to 190Hz. That is -- 188Hz is the Fs of the mid. It's a horn loaded a 10" Precision Device driver. So I need a section (or two sections) to cover the bottom (below 190hz). [/quote]
Herman, i...

From a technological perspective, these look very interesting. Unfortunately the nearest place i could audition these is Montreal, but it looks to be worth it. Have you heard these, Romy, or are you also impressed with the price/technology ratio?

My string quartet have just spent 6 days recording haydn and being assaulted by nasty Genlecs.
I can assure you that this is NOT what I want my system to sound like.
(Actually I sort of began to see the point of them after a while.. but
that's ano...

Thanks, Romy, for your generous reply.
I won't try to address everything about everything, but let me bore
you with a mini-history of what is going on with my playback so you
will understand where I'm coming from and where I'm trying to ...
