Question

Can I put 7 speakers in a 5.1 receiver?

Answer 1

Hmm... How to squeeze 7 speaker via 5 channel (two front, two surround, one centre)?

If you have plans to slot two speaker into one output channel, be wary of this:

- Both speakers must be of even higher impedance than that supported by the amplifier, cause to find the 'near accurate' impedance value from two speakers, you have add both speaker impedance together, then divide by 4.

(For example, amplifier stated an impedance of 8ohms speaker ONLY. So, the two speakers, to play on the safe side, have impedance rating of 16ohms respectively, since 16ohms+16ohms/4 will give you a value of 8ohms.)

Answer 2

You can setup an extra pair of speakers if your receiver has a zone2 output or multi-zone. but you will not get 7.1 sound out of it though...it will just duplicate the sound of your front L and R speakers.

Answer 3

Not as 7 separate channels, no. Also there is no point to do so, since virtually no movies are actually recorded in 7.1 anyway. Most all are in 5.1.

Answer 4

No you cannot, or at least you cannot have 7 seperate channels. Basically a 5.1 receiver can send out 5 seperate audio signals to create surround sound. The .1 stands for the subwoofer. To utilize 7 surround sound speakers, you would need a receiver that can output to 7 speakers. Very few media items actually are coded in 7.1, 95% are encoded in 5.1 so you won't lose much, unless you own like a Blu ray player.

Now if you just want to hook up extra speakers, you can run multiple speaker cable out of one of the jacks. Keep in mind by running two cables out of the same jack, you are sending identical sound to the two speakers. I'm not sure why you would do that, but it's possible. But it wouldn't help you if you are just trying to get 7.1 surround sound. Hope this helps!

Answer 5

No. A 5.1 receiver has 5 sets of speaker terminals: front R and L, front center, and rear R and L. And, if you try to hook up two speakers to one set of speaker terminals, you will get significantly reduced volume out of those speakers. The .1 channel is a low frequency effect (LFE) line out signal (from an RCA jack) that you run to the LFE input on a powered subwoofer.
