| 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 |

| 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. [ September 16, 2005, 01:55 PM: Message edited by: Dukk ] |

| 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....
