I'm looking for guidance re my Lexicon MC1 and speaker setup

Speakers/amps
- Front/center/rear SWAN Diva 6.1’s/ C3/2.1’s <== driven by Cinepro 2K5 amp
- Sides my faithful 30 year old DCM time windows <== driven my my faithful 30 year old Hafler DH200
- Subs two SVS SV20-39CS passive subs <== driven by Samson S700

Here’s my questions:
1) When configuring the Lexicon MC-1 would you set ANY/ALL the speakers to small?
2) What do you recommend re: Placement of the subs?… My options are
- Both in the rear corner
- Both in the front corner
- One in front corner, one in rear
3) What would you set the Sub crossover at?

While I'm at it.... I'm using the TOSLINK connection for the input signal to the Lexicon... Would you recommend anything different?

Any guidance will be greatly appreciated

I would set the sub crossover to around 40-50 Hz (assuming that your front speakers will go that low; they are rated to go down to 40 hz, so that should be the case).

If you set it for a higher frequency it will conflict with the 6.1 speakers too much, which makes the bass muddy and not clear-sounding. Limit sub operation to below 40 hz if possible.

I would only set a speaker to small if its largest driver is 3" or less.

I would use anything available except Toslink. Toslink is well-known for poor performance.

Set the crossover to 80 Hz. Then place the subs at the mid points of the room opposite of each other. They can be on either pairs of wall. See reasoning here: http://www.madronadigital.com/Library/BassOptimization.html

And yes, all the speakers would be set to small.

On interconnect, if you have coax S/PDIF option use that.

I used to have the Lexicon DC-1. Now my son uses it for his PC sound. I have fond memories of it still...
