Mike, I gave some thought to Emerald Physics and Job 225

While I dont know the absolute stability of this amp for bass duties, I can imagine 2 of these amps with an Emerald Physics CS2.3 system (used for about $3.5K, new $6.5K) would make a killer system costing in total between $6K and $10K. You need room for these though as they have 2x 15" open baffle woofers.

I dont see any problem driving the M/HF drivers with the JOB, but the second amp would be driving 4 woofers. However, since they use electronic X-over, the power loss will be minimal, plus the whole thing is like 95dB efficient, so it should work for the bass too.
Having heard the old 2.3 and 2.7 EP systems, I can attest that they cannot be beat for dynamics and due to the controlled directivity, electronic X-over and DSP/DRC control of the drivers and room interaction, I expect thay could take down systems costing 3x as much.

Since you have ever heard the EP speakers, then you KNOW what I mean.

What do you think??
 
Norman,

Mike still talks about this setup to me. Since it's bi-amped, I believe the two Job 225's would be great in this system. Seems like it's worth a try.
 
Norman - this combination would be tough to beat for under 6 figures IMO. The first time I heard the EP's I swore they were $50,000 speakers. I heard a lot worse costing a lot more. With the 2.3mk2's - I ran through my entire demo disk and they passed with flying colors. What my friend Bart kept pointing out was the "reasonably priced electronics and cables" they were using (W4S and the modestly priced Cardas cables).

If I had the room, there are two other systems I would have today:

EP 2.3mk2 with two JOB225's and a DSPeaker 2.0 (Preamp/DSP)

and

Greg's Volti Vittora's with matching sub and some sweet little SET 300B tube amp/preamp.
 
So Mike, with the Mk2, he now uses the DSPeaker instead of the Behringher? How does he do the electronic X-over? Is there another box for that?

Norman, I'm actually not sure. I believe be was using the Behringer in one EP room and the DSPeaker in the other. Maybe both would work?

DSP 2.4





Retail $850.00
The new Emerald Physics DSP2.4 processor is a crossover/equalizer that comes with the CS3 MK2, CS2.3 MK2 and CS2.7 MK2. It also dramatically upgrades the CS2P by extending bass to 24Hz, flattening the entire frequency response and to allow biamping for best sonics.
Hardware
• 28/56bit DSP Engine
• 24-bit ADC/DAC conversion
• 48kHz sampling rate
• Nichicon Audiophile capacitors
• Master volume control on pot


Audio Processing
• Real time tuning
• Upgradeable firmware
• Low/High pass filters
• Graphic & Parametric equalizers
• Level, Mute, polarity
• Compressor/Limiter / Expander
Control
• Software configurable
• Plug & Play USB driver
• WinXP/Vista/7 and Mac OS X Compatible


Dimensions: 3.25W x 1.1"H x 3.75"D

Cool. I believe you could use the DSPeaker with this as well....I believe they adjust this crossover if you are using different amps.
 
I will go check it out.

Perhaps with the 3.0 and subs, he has a passive X-over and the Dspeaker has a sub out lne for active subwoofer and can be DSP controlled by the Dspeaker for room correction issues. Only one amp needed, but you could biamp if you have passive subs. IIRC, Dspeaker can do one active X-over point (for bass/MR separation).

With the 2.3 and up, it would be the "new Behringer -their own version" for sure, as bi-amping is mandatory.

What a story though, 2 forum "heros" combined to make a killer system. I wish I had the room!
