Hi Romy,Yes I would love to hear the same segment from your analog setup for comparison. I think it would be very interesting even though there are so many variables that it probably doesn't tell me much in an absolute sense. I don't really disagre...

Hello guys! I got an old Coral X-VIII from Japan. Its an Onken enclosure with a 400 Hz horn. And I want to give it a second life. The enclosure looks already like new. And the question is about the crossover. What would be the theoretical best points...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

Hi Josh! That was basically my idea too. Although I read that the 12 inch driver loses directivity after 750. But I played around with Behringer dcx 2496, and I had the impression, that 1200 second order was the best sounding. The main reason for cro...

Hi! I wanted actually to get rid of the behringer. Because I have only 1 super high quality tube amplifier and it was difficult to marry different amps with the speakers. And you cant use a high quality dac with the active crossover. I ll right now ...

While seeking for a CD capable of covering a low mid range, say from 300hz or under, I am offered a pair of TOA compression drivers of rather impressive size. Unfortunatelly a seller has no clue what model it is, except "it sounds as seducing as ...

I have a different theory about Koetsu. I think they did make a name for themselves with the Rosewood like you say, but and then kept fiddling and experimenting with different materials. The lacquer coating on the Urushi, for example, then the...

agreed with your comments about the show. I go mainly for the record shopping as the local record stores bring out their better records. I picked up several excellent box sets, including Webern and Bruckner coral music. I also went to see the Airforc...

If time (Endo-san and mine...) will allow, I should also visit Endo Labs of ALE fame... sure I'll have a listen to a 4 ways system in Tokyo area with bass driver and concrete horn.Re. "tilted high frequencies"... no, Roman, it's not me experiencing s...

Hi panwitzResist the idiot-fashion of crossing too low. I recommend at least 1k for such Coral, 2nd order or higher. Also it gives nice lobing transition with the 12 inch (could even improve crossing 1.2 or 1.4). These biradial horns (i love the dept...

Hi! Here is the measured response in 2,5 meter distance living room. 1st order 750. And you can see the roll off after 5k. I know german, so its no problem :) So you have no opinion on the coral crossover from my last post? Only 26 minutes left for b...

Hi all, They look fantastic! I've been talking to Martin recently about some horns for my S2s and he mentioned he was developing some 160Hz horns. I guess these must be them! I already have some of the smaller 340Hz Azuras, but they have 1" thr...
|
|
Ahm, I thought, that the midrange horn loses its directivity after 7000 and thats there I need the h-105. By the way its the only ring radiator from Coral. How can I add at the same time a first order 10k and 5k to the same driver? I always thought t...

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 ...

The idea of making a copy of an s2 driver also intrest me, but i have some other ideas than just copying this driver.I have been thinking to make this driver with an field coil magnet a 12 volts (using a car or camping battery) and a 250 volts versio...

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...

Hi Guy, The Oracle seems like a nice solution - I saw you write up on Peter Empson's forum. They seem compact enough for my requirements. How do you handle time-alignment with the mid-range? Or is this not a problem? To be honest with you I'm not exp...

Hello Roman and friends,Here's a first post from me, to say hi and let you know why I've joined and perhaps ask a few questions...I'm building a pair of loudspeakers, with close to zero experience with loudspeaker building, hoping that the ...

Yes you don't want to go over 0 "dBFS" for sure. In fact it is not good to even hit 0 dB from what I have read in an AES paper. Something odd happens when you play it back (I can't remember the details). I shoot for peaks at -2 or -3 dBFS when...

Hi Romy and thanks a lot for the always interesting topics and discussions going on... I'm quite new to DPoLS and consider the approach of "obtaining sound in a room" more than "speakers positioning" - too often to WAF fullfillment and aesthetics, th...

I never tried the Onyx. I had an Urushi, then a Jade, and now a Coralstone. No I didn't buy any of them in the US so I paid a lot less than the crazy retail prices people throw around. I only know one person personally who did try an Onyx and he d...

[quote user="clarkjohnsen"]Must disagree with Romy that
the M8 is useless and without point. Just for starts, there's Goethe, the
tallest hero of German literature, and his Faust, of which schoolchildren there
must memorize significant portions. [...

We would not use Mahler’s orchestra to play Haydn’s symptoms and we would not use Palestrina’s orchestra to play Brahms. It is not even the deferent time period but rather a different set of expressive tools the symphonic and chamber orchestras u...
