Polk Audio90-RT 3-Way In-Ceiling Speaker - The Vanishing Series | Perfect for Mains, Rear or Side Surrounds | Paintable Wafer-Thin Sheer Grille | Dual Band-Pass Bass Ports for Low Frequencies

Used these for outside covered patio/porch) . Bought 2 of them. (not sure if they are outside rated 😬)They are quite large (tall!) and heavy, make sure you have enough room. I Only have them on a 50 watt amp, but they sound really good. Full detail-good lows, mid & highs! Even more impressive considering they are outside! Installed they look deceivingly plain, you would never expect to get that much sound from a ceiling speaker!Only thing to complain about would be the magnetic covers. They are weak and kept falling off. I had to add a dab of glue to them to get them to stay put, but other than that I am happy with them.

These are up there with the best sounding ceiling speakers available, and even the price is reasonable for the quality. Have previously used the RT70’s which are their little brother and was equally impressed. Note that they do need plenty of clearance in the ceiling (at least about 300mm) as they are not a slim design at all. I enclosed mine inside sealed timber boxes mounted inside the ceiling space to sound their best (speakers are a bandpass design).

Watch out -- this speaker is over 9" tall, and quite heavy. Not for every ceiling, for sure.Read the product description carefully before ordering.Also take care handling it, since the woofer membrane can be touched through the back side.In terms of sound, this is a remarkably detailed speaker, but it is not unambiguously more enjoyable than the more modestly priced Polk Audio MC80.The good -- the 90RT's mid-sized woofer and high-end crossover network produces buttery-smooth, detailed, "present" vocals. In fact, throughout the range, it delivers a consistent level of detail that I have not found in lower-priced speakers, or even many $300+ speakers (with ~10 points of comparison). In addition to winning at detail, the 90RT manages to sound consistently clean across every piece of music I've thrown at it.However, and this is why this is a 4-star review primarily -- this speaker's soundstage feels more shallow and narrow than the more common "open" design speakers -- I am comparing to the great Polk MC80 and the quite good Micca M-8C. And its bass is certainly less punchy than that of either the MC80 or M-8C.So in short, if you need a hyper-detailed front speaker for an audiophile setup **and** you plan on having a separate subwoofer, this speaker will deliver.On the other hand, if you'd like something that is good for a wide range of music, including dancing, and will stand on its own, check out the Polk Audio MC80 for a better-rounded speaker, or the Micca M-8C for a more budget-friendly choice that still sounds very good.

I have four of these set up with a decent center channel in a media cabinet and a fairly good Onkyo amp. The soundstage is huge, and the detail is spectacular. These are meant for a wide range of sounds, and have been excellent for movies. IF you are investing in these, you probably have a sub too. These are easily worth the investment, particularly as they have been in now for over five years with zero failure and epic sounds.Music and movies, these are phenomenal.

After many years, I finally decided to match the speakers in my 7.1 set up. Having Polk RTi A5 as the mains, I decided to purchase a pair of Polk 90RT for the ceiling (70RT were too small to replace current speakers) to replace my old Polk RC60 and reuse my Polk 265RT for the rear, to replace my 25 year old Interdyn speakers. The improvement is far above what I hoped for. The range of these speakers are superb. They match my A5’s beautifully, next step....upgrade the centre to the CSI 6. I consider the purchase of the 90RT as one my best. Movies sound magnificent and concert Blu Ray discs are amazing. Makes me want to relive Farewell 1 from Melbourne again when I get home. Being from Melbourne it is reliving it. The speakers were simple to install, happy with the advice I received, double the thickness of the ceiling plasterboard. These speakers are heavy.
