Cabinets installed and countertops made this week. I'll have the video up soon.
This video is just a quick overview of the Monoprice Amber 8" in-ceiling speaker and some initial impressions. Overall, I gotta say I'm pretty impressed with how well the speaker blends with the Polk LSiM setup I have for the front stage and rear surrounds. If I am only listening to stereo sound from the LSiM 707s and switch to only the in ceiling speakers, obviously there is going to be a difference in sound (mainly bass response which is expected). The highs and mid range (focusing on voices) sound crisp with the Amber speakers, much like the Polks, but don't have as much force and presence as the tower speakers do. Again, no surprise here. If they were just to have some ambient music playing, such as a whole home setup with in ceiling speakers, I think these would fit the bill just fine. I have yet to test them against the Alpha series speakers without the ceiling cans in my bar area, but bass seems decent from the 8 inch speakers. Nothing that will blow your socks off, and you quickly remember what real low frequency response is once you turn on the towers or sub, but sufficient for casual listening.
Now for the real reason they are being used, as a 2 speaker atmos setup in my media area... I honestly think they blend very well with my Polks, even though the tweeters are ribbon compared to the dome tweeters in the Polks. When watching a movie, or more noticeably, an Atmost/DTS X enabled concert blu-ray, the speakers blend in to the sound stage. Everything flowed seamlessly from front to back without hearing any major difference in frequency response or harshness. That was my major concern, the possibility of the ribbons being more harsh than the dome tweeters of the Polks. So far, I have not seemed to notice enough of a difference to say anything negative about the setup. I don't know if the in-ceiling cans were necessary in a home theater setup due to most lower frequencies being managed by the front stage and sub, but thought I would try them out. I'll follow up on the difference with and without the cans soon. I feel most overhead and surround presence is in the mid-to-upper frequency range anyways, so probably not much is gained/lost with the cans and ported feature.
Overall, pretty happy with the setup so far. I need to find some time to rotate the speakers in the ceiling to see if there is any difference in frequency response/presence when listening to the same content since ribbon tweeters have different direction sound that done tweeters. Hope you find the video helpful.
