I have a DC-2. I'm going for a 7.1 system with side and rear speakers. Should I get dipole sides to be used with direct rears, or should I get direct for both? And what about side height? Manual recommends ear level. Is that what you all use? The backs will have to be high due to windows. Back wall is 15 ft wide, so how far apart should they be?

Use monopole sides and rears for the best effect.


Start by placing the sides just ahead of the listening position at the same height as the mains facing each other. You will need to experiment with final placement as you don't want to localize the sounds from your sides.


Depending on your rear wall, you can space the rears further apart and toe them in towards the listening position. Having the rears higher won't be a problem.

I drive DefTech speakers in my Lex DC-2 7.1 setup. I use BP-2004 rears that are set appx. 4' off floor. Mains are BP-2000, and center is C/L/R 3000.


For sides I'm using BP1's (my old rear surrounds from ProLogic setup). These are set appx. 3' off floor level.


I'm using my old receiver to amp the sides, so it's easy to turn them on/off to gauge the effect, which is considerable. I never expected the sides to add that much to the soundfield, but they do.


BP-1's are bi-polar and do a great job, though I may experiment with other options once I get the chance. If I were starting from scratch, I'd probably go with direct speakers for sides.


Good Luck - Gene

i'll be using bipolar BPX's for side and rear as soon as i pick up another pair...

If your use is home theater, I recommend dipole sides and rears.

With the Lexicon (DC2 or MC1), you should be using Dipoles. If you "have a thing" for monopole effects speakers, you need to sell the Lexicon and replace it with a Meridian.


Lexicon's steering logic is based upon the presumption that dipole speakers are in use and they utilize the unique properties of this type of speaker to that end. Meridian's steering logic is based upon the presumption that monopoles are used for the effects speakers.


It is very difficult (if not impossible in the absence of a Meridian processor) in the average room, to use a monopole speaker without localizing the speaker. Clearly you can move the speaker forward/backward of the seating position to reduce this problem. Of course, when you do this, you're now listening to the speaker severely off axis ... not generally where the speaker designer expected you to be.

I'm planning to upgrade my AVP. I use Dev Tech speakers for movies (bipolar BP30s in each courner, bipolar BP1s for the sides, CLR2000 front center, and CLR1000 rear center. I switch to Thiels 3.6s for two channel music. My question is how well will the MC-1 and Logic7 perform with bipolar speakers?

ed,


Logic7 works great with bipolar speakers http://www.avsforum.com/ubb/smile.gif

Called Lexicon yesterday and the tech strongly recommended direct firing speakers for both side and rear locations, and said to use the logic 7 modes without THX processing.


Thanks for the opinions.

Anyone see Home Theater mag?? Seem to recommend dipoles for rear AND for side for best effect with an MC-1.

Everything I've read indicates 3' above the ear level (when sitting in a chair) for the sides. As for the rears, I use the same tower speaker as my front left and rights.
