Bought these to replace some Micca 8" speakers I was using for surrounds and they made a noticeable difference. As in, I never noticed the sound coming out of the Micca speakers before and now these stand out. Especially when setting my system with multichannel stereo and playing music out of them. I'm considering buying 4 of these and using them for my atmos ceiling speakers, but they are so large I don't know that I'll have room to properly align them between the studs with my existing cutouts.

Amazing speakers. They're a must buy. No need to hesitate.

Excellent sound emits from these high quality speakers. Looks great being flush mount too!

A bit pricy, compared to non-thx certified monoprice speakers. They do sound great. I have them in the front and center position.
I am not entirely convinced that these sound a lot better than the (say) Monoprice alphas, which I have in the surround positioin. They are low impedance speakers 4-6 ohms, make sure your amp/receiver can handle it.

Solid build and does very well in my media room with effect sounds while watching movies!

After buying the bookshelf version of these speakers (THX-265b), in the interest of marital harmony I promised my wife to swap them out for in-walls (THX-265iw). I was nervous about buying these speakers due to the limited number of reviews and concerns that they would not get as loud as the bookshelf version, especially since I am using them in a large room which I do not believe these speakers are certified for. My concerns were unwarranted - these speakers are fantastic. They fill the room without distortion. I bought seven of them as part of a 5.1.2 setup and have only installed the front left, center and right, and am looking forward to getting the remaining speakers in place. I am very happy with my purchase.

I had been very curious about these speakers since I came across them. I also thought they would be a great match as height channels for my thx speakers that are a different brand. So on Black Friday I pulled the trigger. These things are really well built. They have some serious heft to them with a metal frame, and an MDF baffle. As height channels they are complete overkill but they sound incredible and mix seamlessly with the rest of the channels. Ran some music through them also, just to see what they sound like and they are definitely the real deal. Very natural sounding and quite dynamic. You could definitely build an amazing home theater with this Monolith THX in wall line, especially if you step up to the 3-way LCR model for the front stage. Very happy I decided to go this route and they look awesome in my black ceiling with the grills off. Lastly, if anyone is interested they measured very well also. My ceiling is an open truss design so it’s wide open and not ideal for speakers but I got -3dB down into the 80s hz region, and the rest of the response was pretty flat considering the open ceiling. My previous in ceilings Klipsch/Polk measured horribly by comparison, especially the klipsch. Anyway, if these were installed properly in a wall or ceiling cavity I would imagine you’d get a decent amount more extension than I’m getting. So, I definitely recommend checking out this THX line, and would still love to hear what a proper 7 channel system made up of these sounds like.

I purchased these speakers to serve as the Atmos channels to compliment my Klipsch THX Ultra system. They provide the kick I was looking for, as I was concerned that just an 8" woofer alone would not.
