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

Not to pile on here, facts are facts.. the Eminence Beta drivers used in these new open baffles are about 50 bucks, the waveguide is about 6 bucks.. And the DSP unit is about 199.00 online, and it is HORRIBLY cheap and not very good sound compared to the DBX P.A. speaker management unit for about 399.00 online, far higher grade..

That being said the design of these emeralds is very interesting.. Not bad, but so easy to copy and get these off the shelf parts and build an open baffle like this that it would cost anybody very little time or money..

Now the real issue comes in on the Multiple needed cables, amps.. and Room acoustics with this design and keying in on the DSP settings will not be for the novice.. So I mean its again interesting, but far over complicated if you ask me with the variety and quality of designs around..

Maybe at 3500 you can't do much better but again as mentioned above this simply looks like a system out of the norm and sorta advanced, but there is nothing magical or advanced done here, quite the opposite be exact, its just a very crude way to keep something very cheap to produce, yet have some advantages over conventional designs IF you can deal with properly tuning and implementing the design in your environment.
Gradient evidence? Not sure how it would replace a 100 db sensitive system that goes down to 20 hz.. The specs on the gradient are 86 db which is not very comparable to 100 db efficiency, and the frequency range on the Gradient is only
45-20000Hz +/-2dB, 29Hz -6dB
Impedance 4 ohm
Sensitivity 86dB/2.83V/1m

This would mean very different amplifiers required(or not required), and supplement of subwoofer would still be needed it would seem if you want to compete with the range of this emerald speaker. Just curious, I guess not all open baffles are created equal.
