[2-Way] I first reviewed these speakers five years ago, and gave them 5 stars for their excellent sound quality. After moving to a new house I bought these speakers again to be installed in the ceiling and used for rear surround. My review is unchanged. These are great speakers, very high quality, and easy to install. They really sound great, as rear speakers or as the main speakers. I'm amazed at how good they sound.

[In-Ceiling] The speakers were delivered promptly. The installation instructions were clear, and the installation was easy except for having to climb a ladder to install them in my ceiling. We use the speakers to play streaming broadcasts and CDs, and the sound has been great.

[Passive] Just wired these up in our Nursery and Cry Room a the church attached to a Behringer NU1000 Amp and they sound great. I ran 16 gauge speaker wire and place a 300 Watt volume control in the rooms. Made the people helping in these areas very happy to not miss the services any more. Easy install template worked great for the cut out.

[30 W RMS ] I used these speakers with JBL 19cs subwoofers for a weight room facility sound system. The total system consisted of 6 - 26c speakers and 4 - 19cs subwoofers. Wiring is made easy with the removable terminal blocks and passthrough wiring. Basically each speaker connects to each other in a line. This installation method reduces cost for speaker wire and labor involved with running extra wire. The terminal blocks have 4 wire holes. For the first speaker in the line will use holes 2 & 3 for the line connecting to the amplifier. Then a wire is ran from speaker 1 to speaker 2. Holes 1 & 4 from speaker 1 connects to holes 2 & 3 on speaker 2. This continues for the entire line. Be sure to properly power these speakers. Both the 19cs and 26c need 140 watts of power. In our installation we used 2 amplifiers splitting the system into left and right sides of the room. Since each amp had 2 outputs of 500 watts for each channel. This provided some headroom for the speakers. On both amps output 1 was was the high and output 2 was the low. Output 1 had 3 26c speakers and output 2 had 2 19cs subwoofers. These amplifiers had a built in crossover feature that splits the signal into high and low frequences which is essential for installing a system like this. A xlr splitter was used to convert the output from the mixer (1 xlr) to inputs for both amps (2 xlr). A cutout template is provided for cutting ceiling tiles. Once tiles are put back in the ceiling the installation can be done without access into the ceiling. The speaker is designed to push up through the cutout in the ceiling tile and clamps down to the C bracket (included). Make sure to have someone assist with installing, these can be insalled with one person but can be difficult for one person to lift, attach wires, put into place, and screw down holders. Overall these speakers work as expected and would buy again. They install nicely and end product looks professional. Nothing less to be expected from JBL.

[Sealed] Due to the relatively low cost, I was a little concerned that these would not satisfy our requirements for the space but man do these deliver. We have 4 of these running on one Sonos Amp in a large living room paired with a Sonos Sub. The speakers are mounted approx. 11ft off the ground on a sloped ceiling. VERY impressed with how they perform!

[30 W RMS ] Across the board... an excellent speaker. I have years of customer install experience in in-wall systems and have to say this model takes the cake. I am very impressed with the dynamic range of the RC55i. Even after the third customer installtion of the RC55i, I find myself wanting to sit down and really listen again to these great sounding speakers. That's something I rarely do.

[9 x 8.9 x 6.3"] I made a lot of comparisons on in wall speakers and for the money and performance against other speakers in the stores the POLK speakers were the best deal. After installing them in my home I was sure my decision was the correct one. I couldn't be happier.

[Sealed] I installed these in a conference room. Work great, sound great, easy to install.

[89 dB SPL] I have installed 8 of these in an new Restaurant there are a fantastic speaker the grill is magnetic which makes them easier to install. The speaker has an extremely low profile the blend right into the ceiling. the centre cone can be adjusted which makes aiming the speaker amazing.

[Sealed] Love the install and sound. Hope I win $1000...
