Review: Thx (not Ultra) certified in-wall speakers. A bit anemic highs, very nice mid. - I have these in my HT setup in LRC positions. These have pretty good bass, and wonderful mid-range. Vocals, acoustic material all sound natural and pleasant. The natural sounding midrange is typical of silk dome tweeters. My AVR is a Yamaha Rx A2A. The one thing I find wanting with these speakers is the treble end. I ended up having to manually EQ the L-R-C speakers ( +2-3 db in the 6khz and above bands) to get acceptable highs. I am using the GEQ "per channel" equalization and NEO Music setting (listening for Tidal). The anemic highs are a problem with all processing options. Given my GEQ adjustments, I am almost happy with how these sound now, but bells, chimes, cymbals still sound a bit muffled, compared to other speakers I have, such as infinity, Micca, or Klipsch bookshelves. The product description is incorrectly mentioning 2 tweeters, this speaker only has a single 1". I have not done extensive wall cavity prep, just braced the drywall above an below the speakers to minimize any rattling / wall resonance. The wall cavities are filled with lose fiberglass insulation. This should be OK because, the thx certification of these was done without a sealed enclosure, so the were designed for in-wall install without a backing box. These go down to 40 HZ, but I have a crossover point set in the AVR at 80hz, Anything below that goes to the subwoofer only. Eliminating the frequencies under 80 hz cut down on in-wall resonance, although the bass is nicer when the speakers are set up without the AVR-s bass management. When mix-and-matching with other speakers, keep in mind that these are nominal 4 ohm speakers. I find that using 8 ohm surrounds and altitude (monoprice alpha-s in this case) makes it difficult to EQ the whole HT system because of the higher impedance of the other speakers. Even when boosting the other speakers' level via the AVR-s speaker management, the other speakers tend to sound weak compared to these. There is probably a sensitivity difference as well, which may further explain why. My recommendation is that at least the LRC and Surround LR should be all similar impedance, similar timbre, similar efficiency speakers. What I will end up doing, is replacing the LR with the 365iw-s and shifting the 265iw-s into the surround position. The 265 will remain as the Center speaker. Combine with a substantial rethink of their wall cavities, reinforcing/bracing and sealing their cavities. so I can run the LR with full spectrum sound. ## Features - Premium drivers high excursion woofers. Silk dome midrange. Silk dome tweeter. Featuring carefully selected drivers that deliver a flat frequency response in the listening window, the THX-LCR features two 6. 5in woofers, a 2in silk dome midrange, and a 1in silk dome tweeter. The silk dome midrange operates in the 550Hz-1. 9kHz range, improving power handling, lowering distortion, and improving the polar response, which allows the speaker to achieve higher SPL. - The 6. 5in high excursion Woofers feature a long fiber pulp cone, NBR Surround, and are designed with shorting rings to keep distortion at a minimum. The combined driver design enables the speaker to reach Sonic heights and deliver accurate sound For the best in home theater dynamics and detail - Precision crossover network: The THX speaker series feature carefully selected fourth order Linkwitz-Riley crossover network acoustic filters. This sophisticated crossover minimizes sonic frequency overlap, reduces distortion, and is an excellent choice to minimize off axis response errors near the crossover frequency. - Easy install: the heavy duty dog ear mounting system makes for a fast and problem free installation. The magnetically detachable grille is powder coated in white and can be painted to match any decor - Timbre match. Same drivers. Same soundscape. Lcr design. The Monolith THX Certified in wall and in room speakers utilize the same drivers and crossover components allowing speakers to be mixed and matched to suit your room! Utilize in wall speakers for the rears and in room speakers for the LCR, and you will remain timbre matched across the Monolith THX family ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YLZ4H56 | | Antenna Location | Home Theater,Window | | Audio Driver Size | 6.5 Inches | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Surround | | Best Sellers Rank | #956,670 in Electronics ( See Top 100 in Electronics ) #1,970 in Ceiling & In-Wall Speakers | | Brand | Monolith | | Built-In Media | in Wall Speaker | | Color | white | | Compatible Devices | Television, Projector, Desktop, Laptop, Home Theater | | Connectivity Technology | Coaxial | | Control Method | Remote | | Controller Type | Ring | | Customer Reviews | 3.0 out of 5 stars 1 Review | | Enclosure Material | Solid material, likely plastic or metal | | Frequency Response | 550 Hz | | Global Trade Identification Number | 00889028095515 | | Is Waterproof | FALSE | | Item Dimensions D x W x H | 3.8"D x 10.7"W x 15.6"H | | Item Weight | 15.7 Ounces | | Manufacturer | Monoprice | | Model Name | THX-265IW THX Certified Select 2-Way In-Wall Speaker | | Model Number | 134368 | | Mounting Type | In,Wall Mount,Window Mount | | Number of Audio Channels | 2.0 | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 200 Watts | | Speaker Size | 6.5 Inches | | Speaker Type | Surround Sound | | Specific Uses For Product | Home Theaters, Media Rooms, Living Rooms | | Subwoofer Connectivity Technology | Wired | | Subwoofer Diameter | 5 Inches | | UPC | 889028095515 | | Warranty Description | 5 Year Manufacturer | | Warranty Type | Limited | ## Product Details - **Brand:** Monolith - **Speaker Maximum Output Power:** 200 Watts - **Frequency Response:** 5.5E+2 Hz - **Connectivity Technology:** Coaxial - **Audio Output Mode:** Surround ## Images ![Monolith THX-265IW - THX Select Certified 2-Way in Wall Speaker, 1in Silk Dome Tweeter, for Home Theater, Easy Install - Image 1](https://m.media-amazon.com/images/I/71wsjoaJG5L.jpg) ![Monolith THX-265IW - THX Select Certified 2-Way in Wall Speaker, 1in Silk Dome Tweeter, for Home Theater, Easy Install - Image 2](https://m.media-amazon.com/images/I/71geB+ZhALL.jpg) ![Monolith THX-265IW - THX Select Certified 2-Way in Wall Speaker, 1in Silk Dome Tweeter, for Home Theater, Easy Install - Image 3](https://m.media-amazon.com/images/I/71B6AnwYiaL.jpg) ![Monolith THX-265IW - THX Select Certified 2-Way in Wall Speaker, 1in Silk Dome Tweeter, for Home Theater, Easy Install - Image 4](https://m.media-amazon.com/images/I/71FeptBHrwL.jpg) ![Monolith THX-265IW - THX Select Certified 2-Way in Wall Speaker, 1in Silk Dome Tweeter, for Home Theater, Easy Install - Image 5](https://m.media-amazon.com/images/I/61sZJPYYJ5L.jpg) ## Customer Reviews ### ⭐⭐⭐ Thx (not Ultra) certified in-wall speakers.
