just wondering.....

 can I split the left and right front stage signals to drive 2 MTM vertical monitors like the n3s's. would like to drive 2 monitors each out of left and right. I would keep them slightly apart and angled out just a bit. just want more volume when having big parties at the house.

can someone tell me pros and cons of a setup like this?

LOL I will know its a dumb question if nobody replies.

thx

I don't think it's a dumb question. [I'm interested in the answer just for the knowledge value.]

I'll throw out a WILD guess and say it'll impact the impedance, so you'd need to make sure your amplifier could drive them all.

Aside from the impedence issues (2 8 ohm speakers paralled will yeild approx  4 ohms) you'd  be spreding the acoustic cneters apart which I'd think will   intorduce a lot of cancelation.  With a single MTM,  you don't have to worry about  that as much as there is only a single tweeter and  the  mid woofers are  able to be kept pretty close to each other.
Don't think  having the  2 tweeters  seperated by 2  woofers is  going to work...  not to mention the  very uupper/lower woofers.   Even teh 1st /3rd  and 2nd / 4th woofers are  going to  end up being  quite a distance from each other (extra diameter of a single woofer)
  Could be mistaken but

hey guys,

 ya sorry, forgot to mention I would use a separate amplifier channel for each monitor, a five channel amp would drive 2 left and 2 right speakers and one center speaker. then another 2 channel amp to drive the other 2 rear channels. just asking because my denon amp sounds way better in multiple speaker mode, which I have in a 5.1 setup.

Sorry, mis read your post, thought you were talking about stacking them  vertically.

Still think there'd be some cancellation side by side....

Good question in that a lot of people have had that idea and used multiple speakers like that before.

What happens though is that the comb filtering effects cause deep cancellation patterns making big peaks and dips in the response.

The information and measurements in this post might help too: http://www.audiocircle.com/index.php?topic=124751.msg1315726#msg1315726

What about spacing two pairs of N3TLs widely apart, say one pair at the front of the room and the second pair at the back of the room?

Depending on the AVR/stereo amp the rear pair could be connected as surround backs redirected to front mains, zone 2 speakers, B speakers (with front pair as the A speakers (stereo amp)), or connected to the surround channels with the crossover set at 40 Hz.

The AVR would be set to multichannel stereo or a stereo amp would be set to both A & B speakers.

It seems this would reduce the coupling and cancellation and still allow for plenty of volume throughout the room without having to have the front speakers cranked up so loud that it bothers those close to them just so the music is loud enough for people at the back of the room.

[Danny Richie]

Speakers from the other side of the room from each other will only cause peaks and dips in the lower regions. You won't have comb filtering effects above 200Hz so much. You will just be dealing with room reflections.

You might try experimenting with running the front pair and the rear pair out of phase with each other. It will smooth out the bass, but might sound odd in some areas depending on the distance you are from each pair. It would be worth trying though.

  thanks Danny, interesting stuff
