yo, just wondering if anyone has any measurements or DSP starting points for a Cerwin Vega rig consisting of 8 x JE-36c and 4 x CVP2153?

crossover slopes, frequency ranges, EQ's, delays etc.

It's system thats designed to be used together so wondering if anyone might have factory presets?

thanks gang

What you really need to know is these are 500w boxes.... NOT 2000w, and the JE36 is more of a kick bin than a sub. It DOES NOT go anywhere near 30hz... the much larger L36 is a 50hz horn so don't try to get anything more from these or you will blow the drivers.

Hi mate, thanks for the reply!

Not sure what you mean by they are not a 2000W box? Do you mean the tops? On the brochure I have, it says the tops are 1000W RMS/ 2000W Peak and the subs 500W continuous, 1000W peak. So all good there, would never put anywhere near 2000W through the subs.

I see what you're saying about not dropping too low. My experience hearing them is that they are a 50hz horn at best too.

You clearly have experience running this system so I'd be interested to know what crossover frequencies & slopes you use and if you have any data or insight into phase alignment at those frequencies?

I wouldn't use an amp capaple of more that 1000w to either box.. CV is notorious for exaggerating specs. Every time I have been at an event with CV speakers I got to witness drivers dying. The 2153 is dual 15" box with a little 1" exit CD crossed at 2khz, this driver will not take any abuse so you have to keep the input signal clean, somebody screaming into a mic and clipping the input on the mixer(like a DJ often does) = blown HF drivers. If you know you are going to be safe from that and the program material has lots of dynamics then peak limiting will suffice, but screaming DJs/MCs and long sustained synth tones requires rms limiting and ideally mic channels with lots of control processing so it cannot be clipped and feedback is immediately supressed.

I would do time alignment if it were my rig but I don't know what numbers you would need, but the tops will be delayed to the subs assuming everything is stacked together. If subs are center stacked with tops left and right time alignment is not possible.

My starting point processing with these would be..

Subs:

40hz highpass 24db BW

80hz lowpass 24dB LR

750-1000w per sub,

rms limiting at 63v if available, if not peak limit at 89v

Tops:

80hz high pass 24dB LR

If biamping 24dB LR crossover at 2khz

750-1000w per box fullrange

750-1000w LF, 100w HF bi-amp

rms limiting at 54v, peak at 63v fullrange

rms limiting at 14v, peak at 28v for HF in biamp

Thanks very much mate, thats a great starting help and good insight to the system!

Just wondering, how come you wouldn't run the sub's higher than 80hz? If they're basically a kick bin wouldn't you get more out of them if you ran them say to 150 ish Hz?

It's because there are dual 15" boxes on top, those 15's make the system naturally a bit low-mid heavy and keeping the kick separate from the "subs" improves definition.
