Can i use RH750 amp with EBS-610 cab?

[zacholistic]

Hi,

I was wondering if there could be problems regarding impedens (ohm ) with a combination af tc electronics rh750 amp and ebs proline 610 cabinet?

The cab is has an impedens of 3 ohms and as far as i know the amp has a minimal impedens of 4 ohms.

the amp: [Invalid or Expired Link Removed]

the cab: Invalid Link Removed

That's an awfully odd impedance. I'd bet you could pull it off without blowing anything up. The 4ohm rating is the "legally let's cover our a$$" rating.

hmm okay but will it have an effect on the sound quality?

I would say stay away from that combo. With a SS head it is fine to go above the rated impedance, but going below isnt the safest thing.

Sound quality? Nope. It will be slightly louder than a 4ohm cab.

If the head survives.

A lower impedance will draw more current through the amp. Its rated at 4 Ohms as a minimal impedance.

Way down towards the bottom they give the min rating as 2.66 ohms. A 4 ohm cab is not 4 ohms, an 8 ohm cab is not 8 ohms. They generally vary. You could get this 3 ohm cab (which is still incredibly odd) and it could measure on a meter at 2.66 or 3.33? Who knows. Maybe find a 4 ohm cab you like to be safe but I wouldn't think you are putting the amp at risk.

The cabinet is probably 2.66666666 ohms on paper, so they advertise it as 3 ohms. I'd stay away from the head/cabinet combination you've asked about.
In reference to the quote above: You can't measure impedance on a standard multi-meter. Impedance is frequency dependant, DC resistance (what a typical multi meter measures) is not frequency dependant. A speaker's DC resistance is lower than its impedance because
