Today I will explain a variation to a surround sound that I originally wrote about some time ago. Back then I simply referred to it as 13.2 channel surround sound. Having finally tested this one in my own home theatre I made some adjustments and it evolved some.
13.0.2 Channel Surround Sound.
First off I’m sure your wondering why the “.0.2”. Allow me to explain ….
The “13” of course represents the number of speakers used. The “0” represents zero powered subs. The “.2” means two pseudo subs (a pair). Like my original posting for 13 channel surround sound I have split the sound from my new Blu-Ray player to allow it to connect to two 7.1 channel receivers. I run one in 6.0 channel mode and the other in 7.0 channel mode. Due to lack of space in my room I do not have any powered subs. For that same reason I am only running two pseudo subs instead of four.
One receiver runs all speakers at ear level when seated. I use much larger, better speakers here. They are 5 1/4″ Polk’s (except the rear center is a KEF). This receiver is an Onkyo and is setup with six speakers. The other receiver is a Sony and runs speakers at two different elevations (ceiling and ear level when seated). The side left and side right speakers run at ear level and are 5 1/4″ JBL’s. Five speakers are Onkyo wall mountable speakers. They are probably 4’s. I’m guessing because I cannot remove the grills and I did not find specs on them (other than the peak wattage and OHM rating they run at). I use a speaker switch on the Sony receiver since it is designed for only one pair of main speakers. My other pair I used are Technics 12’s and they are setup as pseudo subs. I placed one under the television and the other behind the sofa.
I had to, as expected, play around with both receivers (mostly the Sony) to adjust the size, distance and volume on each speaker. This was especially true to avoid an echo with the center channel. When I originally wrote about this I did not expect there to be an echo if splitting the sound from an RCA connection (as opposed to running one receiver with an RCA connection and the other with HDMI. After a few days of testing I have it right and it’s really impressive. My only gripe is that like most movies they still have failed to make the dialogue anywhere near as loud as the action. Perhaps I need to implement my EQ idea for a center channel that I discussed awhile back (in one of my books) to overcome this.
As always have fun with whatever surround sound you choose for your home theatre.
