Polk CS2 Center Channel Upgrade?

[PolkieMan]

Any thoughts on making this unit better or more compatible with SDA 2.3tls.
I have two MW6510's
Would two Monitor 4s be better?

The actual center channels that normally get recommended for matching vintage polks are the CS-350LS and the CS-400. The other alternative is to use a vintage polk.. preferably with the same tweeter. This is easier with non-TL's, cuz you can use any monitor 5, 7, or 10 with sl-2000's or RD0194's depending on what's in your fronts. Do you have RD0198's in you 2.3's? If so, you need to find a vintage polk that's upgradeable to the 198's too. I think sl-2500's are but not sure. I would think a monitor 4 would be a little small. A single RTA-15TL or 11TL would be badass, but you'd need the room.

Thanks I have heard good things about the CS400 and CS400i looks like the CSiA6 is recommended and yea I have RDO 198s. Maybe a single CRS+ or a monitor 5 BTW it was going to use a pair of monitor 4s in series. I guess I can try different things like put the two MW6510 in the CS2 enclosure and order a Rdo-198 and figure out a crossover.

I tried the two Monitor 4s in series, yuck
