Polk Audio SDS 400 - Stereo Dimensional Surround
I bought these speakers 20 years ago, a few months after I bought my CRS+'s
I had them connected to a 4 Channel Amp, I basically split the out put of my Receiver and gave the SDS 400's the same info that my CRS+'s were receiving.
I haven't used these in years. But from what i recall they extended the SDA Effect to around 270 Degrees!!!
I'm willing to take them apart if anybody is interested. Maybe we can duplicate this crossover and retrofit a pair of RTA-11t's to be used with this crossover?
Imagine Adding the 11T's to your room that already has a big pair of SDA's up front?
Here's some History I just found out at Polk Fest 2008:
When i was talking with Matthew Polk about SDA's and the Monitor Series I asked him about these and he drew a blank for a few seconds and then said, "We never sold those, we made them for some of the stores to try out"
So, these things are really rare. Who Knows maybe they do work?
I'll have to hook them up again and see.
Anybody want to see the Crossover?
