I cannot think of any good reason to do this in a domestic situation.I would like to know if anyone is using 2 or more centers, fronts, and backs. Do you like the results? Does it require the need for seperate amp? Or is a quality Stereo enough to get the job done?
In compensation for other problems but not ideal.They have one centre speaker mounted above the screen and one mounted under the screen..
Rear firing drivers are already suboptimal unless they are cutoff below 200Hz or so and angling also is compensating for sub-optimal placement.Angling a single centre speaker up or down can sometimes have an adverse effect..particularly with centre speakers that have rear firing drivers and or ports
Instead of directing the sound towards the centre line of the screen, the sound becomes more localized, infact not angling the speaker can sometimes work better..
Again, it is in compensation for being unable to place the speaker where it should be (and I acknowledge the difficulty without an AT screen). Are all three in the same vertical axis? :bigsmile:The result of this setup is that I get good strong pinpoint voice location across the entire screen, with no emphasis above or below the horizontal centre line of the screen..

It's not the placement so much, just about anyone can find a suitable centre position for their speaker, it's more the type of centre speaker as I've mentioned in the post above..However, if you have a difficult lay out or lack the knowledge or proper testing equipment installing several speakers can correct poorly placed speakers allowing you to obtain the same goal. Is this correct?
Why you want two or more set of speakers???? :scratch::scratch:I would like to know if anyone is using 2 or more centers, fronts, and backs. Do you like the results? Does it require the need for seperate amp? Or is a quality Stereo enough to get the job done?
Both cannot be in the vertical centerline if they are side-by-side. They will interfere with each other.Vitually, yes...The bottom two are side by side (upright), in the vertical centreline with the top speaker..
This is such an odd-ball setup that no lessons can be drawn from it. If it floats your boat, fine.I originally tried it with just one at the bottom, but the top big one ( which has 7 speakers in a 3 way crossover system) is an 6 ohm unit and is more efficient than the bottom 2 way 6 ohm speaker..So I parallel wired the two bottom speakers, and series connected the top speaker, giving an approx. total overall of 9 ohms..The Receiver is set to 8 ohms..
This just about perfectly matched the efficiency of all the speakers..
I only claim that this is only practical when using centre speakers that have rear firing speakers and or ports..
I grew out of these machinations when I was a kid. If you use REW, try measuring a few microphone positions within several inches of each other. Bet they show widely varying results.Why you want two or more set of speakers???? :scratch::scratch:
I have two pairs of front speakers (2L + 2R) :bigsmile: ... I got opinions that I might have problems, but I didn't listen :hide: and set up the two pairs ....
I did it, not because I was lacking sound, the speakers sounded good to me (but, I need to use REW to know for sure how my system is performing) ...:yes::yes:I did it, because I removed a pair of speakers that I was using as surround, and instead of putting them away I decided to add that pair in the front .. now I'm using them with the speaker selector A + B in my receiver.
I gained 5bds using the four speakers instead of two ... but after I use REW, I will decide to keep it or remove it ...:dontknow:
Here is a picture of what I have (you can see that my speakers are small, that help with position)
Do you remember Why is not a good idea to combine A + B speakers???Do you get a "bigger" sound from the dual left and rights?...
This was something that I was going to try, but was advised that it's not the best idea to combine A+B speakers on the receiver..
My problem is that the ceiling if very close (about 12") and if I stack them vertically I'm not sure if they will fit :dontknow::dontknow:I would stack them vertically in a WTTW configuration and see if there is an improvement, especially in the midrange. I have Large Advents so stacked and the sound is incredible.
Most likely because they will be run in parallel, thereby presenting a difficult load to your receiver/amp. Depending on the receiver/amp, this may or may not present a problem. If it's a problem, it will most likely be present at higher volumes, as that's when the most current will be demanded from the amplifier. All that said, I have done all types of parallel speaker installations and A+B installations (my own stuff, I'm not a pro "installer") over the years and have never had a problem. If you find that your receiver/amp is getting hot, distorting or shutting down, then you have a problem. If not, go for it.Do you remember Why is not a good idea to combine A + B speakers???
Yeah, I would have predicted a 6 dB gain, so you're right on target. However, keep in mind that absolute SPL gain isn't the only thing we're going for.I gainned 5 bds using them together (I used the SPL to measure the sound with one and the two pairs and that was the difference) :yes::yes:
I agree that it's cool to experiment. But I think I'm with Kal on this one. Even if REW measures well or the same, I think overall sound will be better with only the one pair of speakers. There's just too much going on with the combining of the speakers. But if you like it, go for it!This is a temporary set up ... I have to use REW to measure the response to decide if I keep it or not.
Somethimes we like to experiment things, Right :bigsmile::bigsmile:
Yeah...That's pretty much it..Most likely because they will be run in parallel, thereby presenting a difficult load to your receiver/amp.
