Need receiver that will push 6 ohms

I recently bought a pair of Pioneer BS-22 speakers to add to my Pioneer FS-52 speakers as I wanted a surround sound effect. But when I connected the BS-22's to my Yamaha R-V502 receiver, the receiver shut down. This is a protection feature that a lot of Yamaha amps have.

All four of these speakers are 6 ohms, and apparently my receiver can't handle the load. So it looks like I'll have to replace it in order to enjoy the BS-22's.

Someone suggested the Yamaha RX-A680, but I can't find any information about whether or not that would suit my needs. I'm open to other suggestions, too.


Thanks!

A receiver that's comfortable with a nominal 3 Ohm load, all 4 speakers at once, is going to be tough to find most will barely handle 4 Ohms. You have to realize that the 3 Ohm nominal load will surely dip lower at certain frequencies so now you're in 2 Ohm or less territory. Does it HAVE to be a receiver?

Just get a surround receiver and run it in stereo mode if your looking for surround effect. Plenty of cheap options at thrifts.

Edit, are you sure you dont have strands of speaker wire touching across pos and neg at speaker or receiver hookups.

Oh wait, this is a 5.1 HT receiver, I thought it was a two channel. It can't handle 6 ohm speakers? Huh.

You do have them each connected to a separate channel, right? LF, RF, RR, LR outputs.

Where are your tone controls and loudness set?

What volume are you listening at?
 
This is a 20 wpc receiver, officially rated at 8 ohms, so there may be nothing wrong with the way you are using it, it's just a low powered receiver that may not be able to handle lower impedance loads.
 
If you have one pair connected to A and the other to B, instead of one pair on A and the other on LR and RR, that's your problem A and B mains are usually wired in parallel and can't be used at once unless you have, in this case, 16 ohm speakers on both.

Speaker wires are connected properly. I've hooked up four speakers on this receiver in the past, but they were all 8 ohms.

Volume is barely up a quarter of the way. With just my two FS-52's, I can turn it up much louder.

Please explain how they are connected.
A and B or front and surround.

FWIW it is not a 20 wpc receiver; 70 x 2 front - 70 x 1 center - 20 x 2 surround
 
Do you have one pair of speakers hooked to binding posts on the receiver and one pair hooked to spring clips on the receiver?
 
Oops, I misunderstood the specs on Cnet, it just says 20Watt, 70Watt.

We do need to know exactly how the speakers are hooked up. There are two ways to connect 4 speakers, neither of which is 'improper' so to speak. Are you using A and B main outputs, or A mains for one pair and rear surround for the other two?

There are two L and R channels in the rear of receiver for a total of four inputs. Main speakers are in one pair, and satellites are in other pair.

If I understand this post, you are running the speakers in parallel (A+B) on the 2 front amps for a 3 ohm load.

You need to use the smaller speakers in the back/surround spring connectors at the top of the back panel, then you will have 1 amp for each speaker.
Make sure the impedance switch (right side - back) is in the down position.

When I looked up the model number from your first post in this thread, I found a picture that showed two pos/neg left/right sets of binding posts and spring clips for rears and center channel. These are all speaker outputs.

If you've hooked two pairs of 6 ohm speakers to binding posts, you are presenting a 3 ohm nominal load. That receiver probably isn't rated for a 3 ohm load.
 
Your R-V502 has IHF dynamic power rating down to 2ohms per channel.

It also appears to have a rating at 4ohms per channel.

It doesn't seem like the R-V502 should have any problems.

He is using 2 channels to drive 4 speakers.
2 speakers with a nominal impedance of 6 ohms in parallel can drop below 2 ohms and Yamaha recommends 8 ohms min for A + B.
