We understand that Charlus’ selection of drivers are not a selection yet but some kind of very preliminary idea of the drivers that he feels like he like. I said “he feels like he like” not accidently. I do not think Charlus, or anybody else in h...

exactly midbass horns are reported to be so complicated to be properly made. [/quote]

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...

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...

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...

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...

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 ...

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 ...

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...

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...

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 ...

[quote user="Kcct82"]Thanks Romy, your comment above cleared some of the questions I had regarding 50/60hz midbass horns.
I found some info on the driver after digging through Japanese sites. I don't know if these info will help interpret with...

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...

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.

Actually you might get some TS parameters for Gotos if you find right

who do. The problem is that those parameters are very much irrel...

Wojtek, Yes, too late. Once you've heard a good "stupid horn installation", there's no going back is there?
Yes, something similar to what was shown in Jeffery's GOTO installation. It should work the same on the floor or ceiling, (...

That is the thing exactly, my upperbass solution has the same output amplitude as the compression drivers I am using, IMHO resistrors are the devil in xovers, they kill all sound. Now the difference between 109 db and 110 db can be overcome with c...
