Any links to sellers of the community drivers?

Could I ask what the Radian 950 actually sounded like on the Eliptrac 400 without a tweeter? I was planning on using this combination myself and have exchanged emails with someone who consulted with Radian on the development of the 950 and I was told the Radian 950 'sports' a lot less artefacts, and other distortion components and will in some measurements look less impressive but it was also stated that the original proto-type had flat extension to 19kHz. Not sure which measurements he was referring to but not sure what to do now after seeing this thread as I was hoping to leave room for upgrade to Be diaphragm. Has anyone heard the Radian 950 on any other horn?

That's ok, thanks for your time. Bruce Rozenblit has answered some questions over on the Transcendent Sound forum re his Sub Buddy which I'll be able to use between DAC and amps. It will act as a high-pass filter to the SET amp and has outputs for subs with the plate amps having low pass filters. Seems like I have a result \(",)/

I thought I could use the natural roll off of the Tractrix to help set the crossover point to the TH and use only a low pass filter. Seems I was being a little optimistic! I want to use the following pre which states subwoofer amps can be paralleled on the output: http://www.transcendentsound.com/Transcendent/Velvetizer.html Edit: Just thought, I could add this into the mix as it acts as a high-pass filter: http://www.transcendentsound.com/Transcendent/Sub_Buddy.html

Ok, sorry for the confusion. I was looking at passive crossover initially so I could use a separate DAC but have since realised I could use the Hypex units and still use my DAC of choice. I want to use: TH from 20Hz (or so) to 90Hz, possibly with Crites woofer but possibly smaller drivers as the TH for these is massive Tractrix front horn from 90Hz to 500Hz, with Crites woofer Eliptrac 400 from 500Hz up, with Radian 950 The ALK ES500 will be between the two front horns, with SET amp powering these, and the Hypex unit is now looking promising for use between the Tractrix and TH, powering the TH. The Tractrix can be built for me by someone else with a talent for it. He already has a five way horn set-up using 15" drivers in TH (see http://www.hifiwigwam.com/showthread.php?54198-5-Way-horn-project-big-boy-system!). The reason I asked here about passive crossovers is due to the fact he (speedysteve) has an active system and I know what recommendations I'll get on there (with good reason no doubt). As I already have some passive parts I was trying to keep it that way but anything is possible at this point. Hope this makes sense, I've had no sleep yet and need to get to bed. Paul

Thanks for your replies Craig. The thing with the active filters like you suggest is that I wanted to use a different DAC. I know a lot of people are putting emphasis on room correction and ADC/DAC etc all in one place, but I wasn't planning on going down this route (at least not right now). I have been looking into this more (and had given up on this thread, lol) and thought a couple of hypex plate amps with built in filters could work for the tapped horns. I have a 211 SET amp, 30 Watts per channel, for the mid/tweeter do you think there would be any problem with this set-up?

I'm putting together some speakers which started out as a Cornscala project but has changed a bit since. I have ALK ES500 crossovers which I am still planning to use but I'm now thinking of adding a tapped horn below 90 or 100 Hz. I would like to use a passive crossover for this. Is there any way of doing this using some kind of generic crossover. I have Crites K33 clone woofers to use above 500 Hz and I'm thinking I may be able to use these in the tapped horns also. If no generic crossover will do, as I suspect is the case, where do I start with designing one? Edit: Crites woofers to be used UP TO 500Hz.

Well this is it. He says it isn't a copy but it seems to me that the man doth protest too much! Seems like a very high price to me, much like all his products.
-
Looking at this it seems they would both need to be crossed over under 500 Hz but my understanding is the La Scala crosses at 500, am I wrong?Could the Q-Pie be made to cross at 500 Hz? Paul
-
Check out his Q-Pie thread. Very interesting. I'd possibly be interested myself but need to cross over at 500 Hz. Paul

http://www.lampizator.eu/newdac/lampizator/Speakers.html Don't know if anyone has posted about these but I couldn't find anything. I thought of Jubilees immediately though he mentions that any comparison ends at looks alone. Seem similar to me. Any thoughts? Paul
-
Good to hear. Thanks Dave and Bruce. Paul

Yes, it will act like a bass reflex but at the same time a horn. In my opinion it is a win win. I would not own another pair of Lascala without the port mod. I tried both port lenths, 10"and 7", the 7 inch was the clear winner for me. Dave I've been planning on using La Scala bass bin with the port mod, and mentioned this to mdross1 over on DIY audio. I'm unsure due to the eq mentioned. I have ALK ES500 crossover networks and wasn't planning on using eq, would this be a bad idea? Also, if I turned them on their sides (to use a larger horn on top) would this be detrimental to the sound in any way? Paul
