Md5150 Posted March 8, 2018 Share Posted March 8, 2018 I'd also like to know how those Radians compair to other drivers. I'd like to get some beryllium drivers but i really don't want to pay 3-4 grand for used TAD's. I'm using Faital HF20AT drivers now and like them alot.

JustAuBy Posted March 16, 2018 Share Posted March 16, 2018 I suppose the Klipsch forum does not email me anymore when my posts are quoted. Sorry didn't know you had follow ups. I love my Radians and will not be replacing them with anything. They are mated to a K-402 horn and crossed at 600hz. I have owned the TAD 4002 which was mated to the Dave Harris Eliptrac horn. I didn't really like the TAD as it seemed dry and brittle to me. My uncle owns a pair of JBL 2441s aluminum diaphragms on a custom horn that I also like a lot but they fall off above 10-12k. The beryllium drivers will play down to 500hz if you want (don't use a lot of power tho) and also all the shimmery highs. The horn is very important though as 2" compression drivers tend to beam on the highs after a certain point. I fortunately don't have this issue. I am not an engineer and do not have sweeps to back up my listening impressions. Just a speaker freaker who has heard a lot of hardware to pick and chose what I liked best.

JustAuBy Posted March 16, 2018 Share Posted March 16, 2018 If I had to but a descriptor on the Radians it would be "Effortless Liquidness". I run all digital media and my chain is structured to take advantage of this. I use Dirac on my pc with a few adjustments to the subs. Chain looks something like this: HF: Atma-Sphere S-30 OTL Amp -> Radian 760Be/K-402 (600hz - 20khz) / PC/Dirac -> Schiit Yggy -> Bride of Zen balanced pre -> Marchand XM44 Balanced XO's \ LF: Hypex Ncore NC400's -> KPT-904-LF (60hz-600hz) Subs below 60hz eq'd through the amplifier seperate from the pc/dirac 2 Quote Link to comment Share on other sites More sharing options...

Non digital active xo and tubes on top. Outstanding. Quote Link to comment Share on other sites More sharing options...
JustAuBy Posted March 16, 2018 Share Posted March 16, 2018 The Marchand xo was really the key to what i wanted to do. I wanted the Schiit Yggy dac as it's an R2R and sounds amazing. Didn't want to use any active digital dsp downstream as it would render the nice DAC upstream useless. So EQ had to happen on the PC which i was fine with. It turned out to be a great setup. Finally found my final form lol. May upgrade the subs later but for now everything is great. Quote Link to comment Share on other sites More sharing options...
Tarheel TJ Posted March 16, 2018 Share Posted March 16, 2018 That looks like a fantastic setup. It is very similar to what I envision as my end-game: Radian Beryllium CDs driven by OTL amplifiers. I think in my case, I am going to shoot for Transcendent Sound though. They are a bit more affordable than the Atma-spheres. Quote Link to comment Share on other sites More sharing options...
JustAuBy Posted March 16, 2018 Share Posted March 16, 2018 I bought the S-30 Atma-spheres used, they are the Mk II model not the updated versions. Cost me $1400, which was comparable to some of the Transcendent Sound options. I went with the Atma-Spheres because I had balanced connections all the way through and didn't want to change. Probably didn't matter in the end but I'm a little OCD on weird stuff like that. Quote Link to comment Share on other sites More sharing options...
mark1101 Posted March 16, 2018 Share Posted March 16, 2018 Have you ever compared the Hypex nCores to the tubes on the HF? I see you use the only on the LF? Any comments about the Hypex sound? Quote Link to comment Share on other sites More sharing options...
JustAuBy Posted March 16, 2018 Share Posted March 16, 2018 Previously i used the hypex on a passive xo for the low and highs. They handle themselves very well and crystal clear. I like what the OTL's do to the mid range for 2ch music however. When i do my theater i will have the HF as Ncores, their dynamics are amazing and super silent.

I thought the Yggo used a Analog Devices set of chips not an "R2R" resistor config? Quote Link to comment Share on other sites More sharing options...

To my knowledge the Analog Devices AD5791 is a 20 bit R2R ladder structure. http://www.analog.com/en/analog-dialogue/articles/20-bit-dac-and-accurate-precision-voltage-source.html Quote Link to comment Share on other sites More sharing options...

What fans do you use as replacements? We use 2 QSC DCA series amps and are looking for replacement fans which are a bit more quiet. Quote Link to comment Share on other sites More sharing options...

Also be sure it's an 80mm fan and you orient it correctly. Here's a small list but there are others. Delta AUB0824L* Delta AFB0824L* Panaflo (Panasonic) FBA08A24L* Papst TYP8414L* SanyoDenki 109RO824H402 1 Quote Link to comment Share on other sites More sharing options...
