Once again, there is nothing specific in this post just some further thinking on the subject, as I keep discovering new idea.
A couple weeks back I was looking at a house that gave in inspiration to think about it. The house was 3 bedrooms Cal...

Scott,thanks I got it now.......

Yes, you right. There are some threads where I should return and finish what I started. The “middbas” section was 80% written but I abandoned it due to luck of time and a shortage of encouragement. I should certainly finish the job. I will find the d...

Hi all
Thanks for your thoughts, Romy.
In my view the least controversial of your “THE PROBLEMS WITH HORNS” cycle. Or, to put it another way, I agree with most of it.
I'm not so critical as you to open baffles for midbass, tho,
in fact I thin...

Romy's quotes in blue:Daniel J. Plach's quote in green:"...The back chamber mechanism is good. Are you planning to do the same in the midbass horn?..."Yes, it will be similar, but more robust; I have an idea for a locking-type seal, which I would pro...

Yes, and this type of woman is, from my perspective, as interesting as your average cabbage.... [/quote]Well, believe or not but they can live together. There i...

I understand your point of view concerning 'vintage' in comparison to 'contemporary'. What I find the most troubling with many of the present/contemporary attempts in design is that many people claim to have a truly horn loaded system capable o...

I concur the objective to acquire performance in the desired frequency range must predominate most other considerations of design.My objective for the design of the mid/upper bass horn is to attain effortless, smooth, real-world horn-loaded response ...

Yes, too low efficiency, even worse than Altec 515, (when loaded with small throat, in proper FLH, NOT A7 type "horn" which disqualified it also for my usage... I don't know how "colored" Tannoy would sound with properly designed...

In considering integration of my own mid-bass horns, and how I'd ideally like to do it, I too passed by the underground, up-firing solution, and very much like this approach. I do however have a preference for inverting the concept, resulting in a do...

Hi Romy,I hope I got this right when going through this long thread with LOTS of information. Did you mention for upper-bass cross-overs Elko’s (electrolytic) only to be your preference? If I have it right, any special preference at all as ...

I keep thinking about power and how much extra power and gain I would need in a new room, Sure, it is not difficult to raise a white flag and do for SS amplification but I so would like to stay with SET amplification for my bass channels! I am lo...

"Indeed for classical work I often find a slightly under damped bass response to be emotionally evocative and of benefit to the illusion of the acoustic"Have you looked at the primary cause of this issue with most SET amps? I can tell you that ...

I spoke this morning with Yoshi and he made a phenomenal comment. He was complaining something about his bass. He uses a pair of big 15’ JBL in a box with an active second order crossover. So, when I asked him to describe what he feels is wrong Yoshi...

Woofers with rubber surrounds tend to have boomy bass. While accordian surrounds seem to have much tighter bass and more accurate sound reproduction. So adding more then one woofer to an enclosure would make the problem 2 fold. It would be much bette...

[quote user="Paul S"]Amir, what you say and the simple way you put it is indeed a very important consideration for speaker/amp matching, and it is something that one must actually hear and cultivate in the first place. Since there is no way to emperi...

Again, Romy, nothing short of amazing that time, energy and focus came together for you! And good to hear that you are still getting Music from old CDs. I hope it goes just as smoothly for you when you turn back to LPs.If you said anything about your...

[quote user="Romy the Cat"] The major minor thing remains to find different lower bass. I said “minor” thing as my lower bass is not bad, in fact I do insist that it is very proper lower bass as I did set it up lately properly…..Despite that I in...

[quote user="haralanov"]Romy, the main driver in this acoustic system has nothing to do with the funny Lowthers. It is very high class field coil speaker unit made by Oleg Rullit. The owner of the system has tried the highest class of the Feastrex li...

Interesting take on the Altec 820. No way can this be done for 20k. Looks like dipole bass with some attenuation for mid frequencies.Wolf von Langa has a faintly similar take on the Altec 820: [url]http://www.holgerbarske.com/allgemein/fremderregt/#c...

[quote user="Vasyachkin"]has anybody tried a horn speaker with a dipole bass section ?[/quote]Well, I must say that I have tried dipole bass in a few configurations, including dipole bass plus horn, however I think this is completely immaterial to th...

I'm wondering has anyone actually tried using the pro sub horns, similar to EAW LA400 (about 36"x36"x24" or similar size). There are a few different products available, such as Fitzmaurice tuba, EAW, based on a 15" or 12" woofer. What are your experi...

Since having replaced the 16 Ohm drivers in my upper-bass horns with 8 Ohm versions of the same driver, I gained enough upper-bass output that it is now possible to run all horns from the 8 Ohm taps (I was previously running upper-bass from the 16 Oh...

Putting The Mid Bass horns behind your head will not work. This thread was about Mid Bass Horns Project, do you thank you will be able to use any frequency above 80 cycles with rear fired horns that are behind your head? That is a Joke. It looks more...

[quote user="noviygera"] Vasyachkin, if this is still relevant:I've tried dipole bass and dipole mids with horns mid/highs in my system. If anything, dipole works the WORST for the bass and here's why:It does not load the room with bass pressure (or ...
