    • Re-posting this from "Home Theater" forum. Why is the frequency response of the RP-150M better than the RP-450C ? Based on the cabinet size and number of woofers, it seems that the RP-450C should have the better/lower frequency response but it does not. Why ?    RP-150M: 
      Frequency Response: 48-25kHz +/- 3dB
      Dimensions: 14.57” (37.0 cm) x 7.67” (19.5 cm) x 10.67” (27.1 cm)
      Volume: 1192 cubic-inch
      Power: 75W/300W
      Woofers: 1 x 5.25" 
      Enclosure Type:  Bass Reflex   RP-450C: 
      Frequency Response: 58-25kHz +/- 3dB
      Dimensions: 6.81 “ (17.3 cm)x 31.13” (79.1 cm) x 14.51” (36.8 cm)
      Volume: 3076 cubic-inch
      Power: 150W/600W
      Woofers: 4 x 5.25" 
      Enclosure Type:  Bass Reflex   Kris

    • It comes with a remote, that you use to control the colors and other settings.   I actually prefer leaving the white LED on when watching TV, heck, I now leave them on 27/7 m. It makes everything look “crisper” for some reason.   Here is what I ordered: https://www.amazon.com/gp/aw/d/B0788Z13K2?psc=1&ref=yo_pop_mb_pd_title     Sent from my iPhone using Tapatalk
    • I've seen others use that kind of backlighting.  How do you control the colors?   Is there a practical use for the lights, ie makes the TV look better, easier on the eyes, etc, or is the lighting purely for effect?
    • No wonder she won an Oscar for this! That was quite a monologue. 
    • Yep, like a K43, as I discovered. But for those who want some really great drivers. AE are tops. Expensive but worth it.
    • Thanks to a fellow forum member’s recommendation, I picked up some LED lighting to go behind my TV. Very good use of $40!
