RF3 vs RF82

[mattSER]

In general, yes. Rf-3s and RF-82s are both rated at 8 ohms, so when you hook them up at the same time, the nominal impedance drops to 4 ohms.

 

However, this doesn't account for impedance dips. Each speaker probably dips below 4 ohms, so connected together they drop to below 2 ohms.

 

That's a tough load for any amp, but at least we know your amp is rated for 4 ohms, so it's not that bad. If it was an 8 ohm amp, it probably would've been toast already.

I would think the worst case scenario would be the amp going into self protect and shutting off. I've done this several times back in the day with older Receivers and never had one fail because of it. I know with aging equipment things don't always work the way they should though.

im about to be homeless in a day or so, but all i keep thinking about is upgrading my rf-3's. maybe sleep in the van until i have enough to get a set of rf-7 iii's?
