Hello all (from Thailand)!I found this very intersting horn society here by accident and would like to show and share my first experience with horn speakers system.It's consist of 4 way system .[IMG]http://i245.photobucket.com/albums/gg69/krairerk/hi...

Ming,
thank you very much for resonance information, it explains a lot about the SG145LD4’s suspension. Still, my primary interest was not how folks out there build 20Hz of 24Hz horns but about ability to use the SG145LD4 properly for smaller horns...

Hi Romy,as distributor of David Haigners products to Austria and Germany I think I should make some comments on your...hm...review of a speaker you have never heard.I will not comment on the theory of CD horns here. It should only be noted that the A...

[quote user="jessie.dazzle"] Color or opacity of the material in itself means nothing; it could very well be white, pink or have leopard spots (I'm betting you'd like that!), all independent of its physical characteristics. [/quote] Of cause the colo...

It is a shame that I keep finding threads about a 300Hz compression driver channel, that ends abruptly. I have been trying with a not-so-exact Goto S-150 replica (~1.7m deep, 75cm diameter mouth), and I know of another fellow in Sweden who tried the ...

I kind of got stuck in selecting an upper midrange driver, above 2kHz. If a driver is going to screech in your ears it is going to be in these frequencies. I was never really satisfied with the range of 1" compression drivers I tried. That is wha...

Hello,Can you give me some ideas for a good room? Also, audio related ideas are always welcome too.The initial plan is a room with 5m H x 10m W x 14m D (about 16,5ft H x 33ft W x 46ft D). Solid floor, probably porcelain tile (chess floor style), and ...

Paul,
Ok, I would agree with this. The power handling is the factor that I forgot to mention. The Japanese home drivers are rated for a few watts vs. the pro driver are rated for hundreds watts. BTW, some of older pro drivers (like my Vitavox) wer...

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...

Ok; there's a mis-print somewhere, or a manufacturing change... The web site linked listed SG-370 as 23,000 gauss, and SG-370DX as 24,000 gauss. The goto brochure lists SG-370 as 24,000 gauss. And was discussed yesterday w/ someone, one doesn't re...

hi Dominic i made myself the same question regarding the high frequencies in the orphean horn. the reason is probably because this horn has no compression, and the horn length is not so deep, and the exit diameter is 2 inch, quit big. If you read my ...

With that Moscow guy it is not the question of his reliability but his sanity. I hope you understand
that response he gets is rather a measuring of his horn then measuring his
driver. He unfortunately neither intellectually (audio-wise) not psychol...

[quote user="Jeffrey Jackson"] so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet of plywood) and have a mouth roug...

It is very easy to figure out acoustically. Feed the drivers and their crossover with a reference tone of fixed amplitude and fixed frequency, roughly in the middle of crossover point. Disconnect one of the drivers and measure the acoustic pressure e...

So, I guess you do not measure flux if are getting. You might measure sensitivity and we might presume what when perm magnets has the same sensitivity as electromagnets then the drivers have the same magnetic flux density. Let also presume that when ...

Thanks for the wise, simple instructions, Roman, also useful to others, I believe... that's what I actually do since I - 'twas ONLY 15 months ago... - became conscious of the limits of my tuning-by-ear and got my IVIE IE-30 with Class A measurement m...

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...

[quote user="Kcct82"]Thanks Romy, your comment above cleared some of the questions I had regarding 50/60hz midbass horns.

A few months ago a reader of my site contacted me and informed about that he found a very interesting driver, that his is using and he is very excited about it. The driver is JBL 2490.

Hi Romy…and fellow audio nutters. I’ve bitten the bullet, and shifted from BLH to front-loaded. Yes, I was an idiot, a moron for not doing this sooner. My project is ‘humble’ by Romy’s standard…but I feel it meets the following objectives I h...

Haralanov, I do not think that the “information” that you found is indicative of anything. If they changed coils and diaphragms on their LOMO drivers (and I presume that if they change the diaphragms then they did not keep the LOMO original suspensio...
