Do these come in white?

Thanks for your question. The Polk R300 is available in black or walnut. White is not offered. World Wide Stereo is 43 years old and a proud authorized Polk Audio dealer.

Can a marantz cinema 50 powering only the center and 2 surrounds, l/r on external amp, power the r300 to get the most out of the speaker?

Yes, the Marantz Cinema 50 will power the Polk Audio R300 nicely. This will make for a great pairing.

I have a 20” wide hole theater cabinet. the blacks and sides are sealed. should this work despite the port? should i “open” the cabinet in the rear?

Thanks for your question. Fully Sealed Speaker Enclosure: Eliminates chuffing and distortion for crisp, clear, easy to understand sound. It has no port. World Wide Stereo is 43 years old and a proud authorized Polk Audio dealer.

Can this center take a full 200watts from an external amp that bridges at 200watts x1 into 8 ohms?

Most of the time when a two channel amplifier is operated in bridged mode there is an increase in crossover notch distortion. Most amplifiers sound best when left unbridged.
