when I downloaded the manual for this sub off the web site, the specs for the OHMS say-revc ( DC VC res )-2.97 OHMS. does this mean the OHMS for this speaker is 2.97?

Thanks

sweet sub, surrounds are like frickin tire rubber, don't over extend it however the voice coils will snap.. not sure on the ancwer some one will be along

ftp://208.187.38.55/Phoenix_Gold/Man...akers/XMax/12/

this is the link, it is the 12 on the right

please help

Thanks

That is the DC resistance for the driver which is usually a little less than the AC impedance that is actually important.

Therefore it appears to be a "4ohm" woofer.

I have an original Xmax manual from back in the day when I had bought mine.
Revc (DC VC) is given as 3.89ohm in the specs list and it is a 4ohm driver.

They made two drivers one had a revc of 3.89 and the ather is 2.97 I have the 2.97 one. I've never heard of a SVC sub being less then 4 OHMS!
is there such thing?

thanks

the x-max series were all single voice coil 4 ohm. manufacturer's tolerances may allow some differences from the spec, but nothing considerable as this is a high quality driver with fairly tight specs.
love my 15"!!

I'm putting it into a ported box with an amp that will put out 650 rms into 4 ohms, going for SQL type sound.

is this subs watt rating in RMS?

thanks

the first series was rated at 600 wrms, the second at 500 wrms. i think you may be overdriving it with the 650 wrms... as in all cases, the use of it will determine its longevity...

DC resistance and nominal impedance are going to be pretty much the same number.... the reason the '4ohm' coil actually reads 2.97 or whatever, is to account for power compression....

At a working temperature the new DCR will be much closer to 4ohms....
