Audiophile quality sound with in-wall invisibility. What once seemed like a contradiction is a reality with the introduction of the high-performance Jamo IW 827 LCR custom speaker, thanks to the use of award-winning Concert Series C 800 components.
Utilizing the key engineering principles that have made the Concert Series speakers a popular choice for movie and music enthusiasts, the IW 827 LCR is a versatile design that can be used as left, right and center channel speakers in an advanced home theater/audio system.
Core Concert Series technologies, such as Decoupled Tweeter Technology (DTT), WaveGuide, Hard Conical Cones (HCC), Active Impedance Correction (AIC) and solid aluminum center plugs are all found in these high-performance models. Created for audio purists, their quality and attention to detail reflects Jamo’s highly focused approach to custom products.
The IW 827 LCR is a 2.5-way design with a 1-inch DTT silk dome tweeter located between the 7-inch woofer and a 7-inch midrange/woofer—both featuring high-end fiberglass/honeycomb composite drivers. This design, coupled with a unique crossover, achieves excellent vertical sound dispersion without the midrange cancellation that can happen in a traditional two-way speaker’s woofer/tweeter/woofer layout.
The driver configuration gives it a slightly downward optimal listening angle; in other words, it can be installed next to a flat panel TV or alone, relatively high on a wall, and still deliver optimal audio to those seated in the room.
According to director of product planning Rune Karsbaek, the IW 827 LCR is consistent with Jamo’s overall philosophy, despite being an in-wall product. “While we’re widely known for the beautiful Danish design of our cabinets, our unique, open Danish sound is just as important. These speakers reproduce music and soundtracks with all the vibrancy of our Concert Series, but also provide a discreet, built-in solution for any living space.”
For installations that require a sealed back box, the speaker has an available two-part enclosure. The halves are identical and are lined with damping material. By using separate boxes for the upper woofer and lower woofer/midrange, the possibility of mid- and low-frequency interference is greatly reduced.
The IW 827 LCR is scheduled for release next month. It is priced at $799 (U.S. MSRP) each; the optional two-part back box is $199 (U.S. MSRP).
About exclusive Jamo technologies:
# Decoupled Tweeter Technology (DTT): A mounting system that prevents unwanted cabinet and wall vibrations that can cloud or color sound.
# Hard Conical Cones (HCC): This technology allows for extremely low distortion throughout the range, as well as creates a very open and detailed mid-range for optimum voice reproduction.
# WaveGuide: This technology, which involves the shape of the tweeter’s faceplate, helps control the sound pattern for a more open and dynamic experience, as well as makes it easier to position the speakers in a room.
# Active Impedance Correction: AIC results in reduced distortion in electrodynamic speakers, reducing roughness for clearer midrange, particularly in vocals.

Who doesn’t love sub-woofers? I mean, even the name is great. Hook one of these bad boys up to your entertainment system and it’s like having a movie theater in your living room, only without the little 2 year olds who talk or cry throughout the entire film (unless you have kids, then you’re kinda stuck.) If you can’t get enough home entertainment gadgets, then you’ll love the new BX-4850 Ultra2 In-Wall Sub woofer, introduced at CES on January 8th.
BG Corporation and THX Ltd.—the two leading manufacturers and providers of such technology—have joined forces to produce the first in-wall woofer for the modern home. This bad boy also incorporates THX Balanced Bass-line™, a new THX technology that delivers vibration-free bass. Incredible bass with minimal distortion. Laurie Fincham, Chief Scientist at THX said that: “The slim, yet elegant design minimizes the often hollow, unnatural bass sound caused by wall vibrations, ensuring that homeowners don’t experience distracting vibrations during their favorite movies and musical presentations.”
Not only does it have all the newest features, it’s built into the wall, blending in with the rest of your house. “The tall, slim profile of the BX-4850 Ultra2 Subwoofer is unobtrusive and blends harmoniously into any décor. It just disappears into the wall, yet delivers incredibly powerful clear sound with virtually no distortion,” said Paul Kahn, Chief Executive Officer of BG Corp.
All you’ll see is the tall and slim grill 26 inches high and 4 inches wide. This sub doesn’t rely on the wall cavity or a separate back-box, and can be installed completely in the standard 2×4 stud wall.
Powered by 2,400 watts of power, the BX-4850 offers outstanding playback of your favorite movies, video games, and music. If you are a hard-core home theatre junkie, definitely take a look at this baby. It’s expected to be available through BG dealers later this spring.

In-wall speakers. Everyone has heard about them and many can easily identify them by the hundreds of little holes in the grill on the wall or ceiling. Flush they are, but hidden they aren’t. But it’s better than having a huge box hanging off your wall or standing from the floor, right? No.
Now with the help of NXT technology, you will no longer have to sacrifice the beauty of your wall or ceiling with an eye sore of a speaker grill. Amina Tech today announced SoundUnseen™ Plaster-In-Wall Speakers that it will be showing at the CEDIA (Custom Electronic Design and Installation Association) Expo in Denver, Colorado starting September 13th. Like the name implies, these babies can’t be seen as you mount them flush into your wall or ceiling and slap some plaster, paint, or wallpaper over them. Gone. Hidden. Out of sight. But walk over to your stereo system and crank on the tunes and be amazed by the sound that literally comes from your walls!
The high-power vibrational elements in the flat speakers produce sound in the same way, “as natural musical instruments, as with the acoustic guitar, violin or piano,” do by vibration. Amina Tech told SvenOnTech that, “This diffuse source creates a high-definition sound over a very wide area, ensuring that a surround sound or stereophonic sound field can be heard regardless of room size, shape or listening position.”
With speakers ranging from 20 watts (8 ohms), to 60 watts (4 ohms), or as high as 80 watts (8 ohms) in output, with a maximum SPL of 95db 1m/20w, 99db 1m/40w, or 105db 1m/80w (respectfully), and a frequency range of 100-20kHz, all tied up via butt splice crimp or 2-part polarized connector, these in-wall sound emitting devices sound pretty interesting. SvenOnTech already jumped on the offer to put these into someones home, and if we get a set to try out, we’ll be sure to have the big spread on this with full dets on how they sound. Heck, we may regret our decision to put it into our brother in-laws house and not ours if they are as good as we think they’ll be!
