Emerald Physics CS-2, Opinions Please


Hello all:

I found and read a couple of older threads regarding these speakers, I've been talking with the dealer, and I have read everything I could find on the internet. I understand the DSP's role and the need to bi-amp. The last step befor I plunk down the plastic, is to ask those of you that have them what you think?

What are the pluses and minuses? If you have had them for a couple of months are you still happy? any regrets?

Best regards,

Dave

Wow, I seemed to have stirred the pot.

No point in attacking Tvad whom I hardly know. I'm the one who did not like the speaker.

Paul-If you want to know who my dealer friend is feel free to send me a PM. I have nothing to hide. I call it as I see it. The reason I didn't disclose the name here is that I'm basically saying something he used to sell is not that great. Although it wouldn't be the first time.

As for EP having only one dealer, that seems to be a more recent event. EP had a great showing at CES and a number of dealers picked up the line in January. My friend started carrying the line after the show. He was not the only one. I remember seeing several dealers advertising the CS2 after the CES including here at Audiogon. I first listened to the CS2's in mid February; the speakers arrive about a month after the CES. As I of my last visit to my friend's shop, he had sold his demo CS2 and he is not carrying EP anymore. Which is in agreement with the new single dealer policy. Dealers change lines all the time.

BTW-when I say I hang out at the store, I really mean I hang out at the store. I have often referred to that place as an audio version of Cheers.

In my original post, another friend of mine did listen to the CS2 at another dealer I know in LA. That friend liked the CS2 and I do trust the dealer's taste since I used to hang out at that store when I lived in SoCal. It is ironic. Another of my friends listened to the pair at my friend's store and did not like the speaker. The three of us went through the exact same arguments in this thread via e-mail for several weeks. Feels like deja vu.
Interesting. I have not heard these...so no comments on the sound.

The CS2 system is a stereo, bi-amplified design requiring a high and low frequency range amplifier for each channel......Passive crossover networks in conventional speaker inflict far more damage to the signal.

Little by little the word is getting out about the benefits of eliminating passive crossovers from speakers and using separate amps for treble/mids and bass. Another convert to active speakers! It is great to see speaker manufacturers that embrace technology and progress instead of devoting the largest portio of their efforts at simply making better looking "furniture".
Rchau,

For the record, I was not insinuating that you made it up. I just found your dealer's reaction quite surprising given that, at the very least, these are simply very good speakers. I would say that the reactions I have seen/heard (dozens) have been probably 95+% positive - most very positive indeed.

As for them not being 'revolutionary' - so what? With speakers, the devil's in the details. And, frankly, they are rather innovative. The magic seems to be due to the combination of very complete frequency response, correct dispersion/power response by the ingenious coupling of open-baffle and a waveguide (the guide takes over where the bass drivers are beaming) (power response is THE critical area neglected by almost all conventional designs), and the complete time/phase alignment offered by the DSP. The result is a speaker that honestly seems to have no dynamic compression whatsoever, has accurate timber, and portrays a very realistic soundstage.
[A lot in common with Duke's designs, incidentally, which also get around the power response problem by coupling a woofer to a similarly-sized waveguide. Duke, if I'm screwing that up please correct me!]

There is no such thing as a perfect speaker, and there are probably better speakers in certain ways, but these things did drop my jaw at RMAF last year and yes, I did finally order a pair.
These are not active speakers - they are speakers that use an active crossover.

To me, active speakers - putting the crossover and amps INSIDE the speaker to ensure that it gets the worst affects of vibration possible - is and was a compromise based on convenience, not sound quality.

In my experience, *simple* passive crossovers are Ok and can be a great solution. Complex passive xovers, however, steal far too much of the signal to be tolerable.
Paul-I never for a moment thought you were insinuating. I was just offering since you asked.

My parting commennts.

I do agree with all of the CS2 advocates here that the CS2 are not dynamically compressed. It is unfortunate that a lot of speakers these days are dynamically compressed.

My main point in my original post was that there are a whole class of speakers out there (many decades old) that have the same characteristics as the CS2s and it is worth taking a listen. Unfortunately, most of these speakers are not in the mainstream audiophile consciousness at least in this country or thought to be too old to be any good. A little education goes a long way.

Paul-your comments about your friend Duke's design is interesting. In my original post, I mentioned the old Western Electric 'wide range' speakers. I did not mentioned that they weren't actually that great. They had a variety of problems. This led to the famous Shearer horn, a two way speaker with a multicelluar horn on top and a folded bass horn driven by a dynamic cone driver. BTW-a waveguide is just another form of horn.
