I had the chance to sit down with Steve for awhile yesterday and I ask him what his thoughts would be on your questions. I'm assuming you are planning on a 7.1 channel system using the 2nd pair of TF-600 as "width channel" speakers.
Steve suggested that the front channel speakers should be 8'-12' apart and 2'-3' off the back wall, both looking straight ahead. The width channels should be moved forward and also 2'-3' off the side walls but need to have a toe-in so that the sweet spot (see insert in the middle of the diagram) points towards the listening area. You could use the TimeWindows as side surrounds, again with the same distance of the side wall but have the apexes looking at each other. The Tf-350's could be used a back surrounds in you like. He also suggested that you could put the TimeWindows in the back and to set the crossover for the TF-600 for 40-50 Hz.
You did not mention a center channel speaker. Also, if you were planning on using two of the TF-600's on just one channel, Steve said he would not recommend that.
WOW, Sir. Thank you very much for the time and detail. It is very much appreciated.
I am using a KX-Center. I have built the room wired for 7.1, however I am using a Carver CT-17 as the pre-pre-amp for 'video audio', and as such it only supports 5.1 which is ok with me for now.
This is all part of an 11 amplifier system I have put together over the last 20 years, totaling almost 5500 watts. All of the front 8 are Carvers, supported by the second pre-amp, a C-11. The center and rears are Marantz mono-blocks. I have four dedicated bass (crossed over) amplifiers, so if placement at the back wall is for low frequency response, that's not entirely necessary. If its for tweeter reflection, then I may have to rethink some things.
I will be dedicating 2 (250x2) amplifiers for the 600s. So when you mention "if you were planning on using two of the TF-600's on just one channel, Steve said he would not recommend that." do you mean one amplifier channel(which is definitely not a problem), or one stereo channel (which would definitely be a problem)?
I am more concerned with 'pure stereo' front channel and creating an audio sound stage without surround or center, (simulated or otherwise)
Do you think there would be much difference in set-up?
When you mention 'width channel' I assume we are still talking about the main stereo front channel, right and left.
Thanks again for your attention. I can't tell you how surprised I was to see this. I am super impressed by your attention to detail in building that center channel. I have scanned a few of your posts.
Btw, I live in the Grand Rapids area. If you or Mr. Eberbach are ever in West Michigan, look me up.
