Hello I currently own a Pioneer VSX-31 reciever and it works fine for what I do (movies & light listening to music). I have come across the opprtunity to purchase my brothers 6 month old speakers for a favorable price. The Speakers are german mastro formerly mb quart alexxa series The set I am being offered includes the front mains, the bookshelves, and the center. I can only find specs on my reciever for 8 ohms but thses speakers are 4 ohms. For my use will my reciver work or will I have to purchase a new one. I don't care much for obtaining maximum output from the speakers as Ilive in a basement suite, but I don't want to damage the speakers or my amp. Anyone that can help me out please respond.


Thanks

According to the owner's manual:

Guaranteed speaker impedance...........6Ω to 16Ω

Looks like it's not meant to power 4Ω speakers. You might be able to get away with powering 4Ω speakers at lower volume levels, but I wouldn't risk it.

for sure the VSX-30 and VSX-31 are NOT capable to run 4 Ohms speakers for long period of time. Can't remember about VSX-32 but for 100% sure, VSX-33 can run 4 Ohm speakers, SC-35 and 37 can even run Martin Logans (rated a 4 Ohms but at certain frequencies they go down as low as 1 Ohm).

Just pick up a 2 channel amp to run your Mastros

Rather than spending moiney to get a separate power amp that will run 4 ohms, you might as well return the VSX-31 and use the money to buy 4-ohm stable power amp ( which runs in about $500 or more, to get a VSX-33. This way you'll get not only MOSFET amp for all your channels, you'll also get a much more accurate version of MCACC and a better scaler (Marvell Qdeo - that accepts digital inputs to be upscaled too; this wayn you 720p HD box and torrents will be able to be upscaled beautifully).

Cheers!
