Using two sets of front speakers

Ripping Rudy

Hi everyone:

My Yamaha receiver allows me to hook up two sets of front speakers - A and B

What would be the reason to do this? Could I run a pair into another room or something like that?

Thanks!

Yep, that would be a good application of that feature...or if you wanted to use smaller sattlite speakers for 5.1 stuff but want larger front speakers for 2 channel stuff would be another reason...

I suppose you could use the A & B outputs to bi-amp a pair of speakers.

Does anyone see why this wouldn't work? I think it would.

I'm not sure about the particular AVR in questions, but most receivers won't let you power A and B channels simultaneously...thus ruling out bi-amping capability.

Also, many receivers that will drive both simultaneously will only deliver half power to each...

I don't know of many receivers that will deliver full power to boths sets at the same time, though I'm sure there are some...

My receiver is a Yamaha HTR-5590 if that helps. I'll check the manual for how it works.

I don't know about todays HT receivers too much, but a couple things you could do with old amps that had "A" and "B" speakers that could be used at the same time were:

1. Bi-Amp

2. Have one pair speaks in one room and one pair in another room (both playing the same stereo program).

3. Have two pair of speakers in the same room, both as fronts playing the same stereo program.

a) Stacked Advent's - Some folks used to stack one Advent Loudspeaker atop another, with the tweeters meeting in the middle.

b) If I had two pair of the exact same speaker, I would be tempted to mount one behind the other, with their two back baffles meeting. Same thing Blose was trying to do, but here we use quality drivers that can reach frequency extremes.

Curiously enough, I had four of the exact same speaker here several times, and never tried it. I had 4 Polk RTA 11's, and 6 KLH Model 6's at one time.

I run LSI9's and LSi15's as fronts, 15's are A and 9's are B. I usually have both playing, but late at night i just run the 9's direct without a sub. I have always liked having two or more pairs of speakers for my fronts. In two chammel, I feel you get a robust soundstage. But truthfully, with the quality of the LSi's, You can hardlt tell the difference between the 15 and 9's. Of course the 15's have a more pronounced bass, but if I had to choose one, Id go with the9's...duh that slid of topic, a and b in front are cool

how do u find out if the receiver is delivering half power when the A and B channels are run at the same time? my receiver allows me to run them at the same time, but i dont know anything about the wattage it puts out to each speaker.

Rudy,

I have the Yamaha RX-V1400 which is similar to your 5590. I run 2 pairs of RTi100s for fronts, CSi40 center and 4 RTi38s for rears and surrounds. A and B share the wattage for the fronts. It sounds better to my ears with both sets of 100s playing in the front. Just set it up and give it a listen. Do what sounds best to you.

Hope this helps,
Jman
