In-wall speakers Polk Audio LCi-RTS105
American Polk Audio LSi-RTS105 among all embedded speakers collected in this survey produces perhaps the strongest impression as the characteristics and performance. It is a large, heavy, designed for very high power input acoustics were designed for use in large home theaters and complies with THX Ultra2. It is equipped with two anthers (perforated metal grill and plastic frame, which is stretched thin fabric). Has attachment by turning "dogs" and does not require disassembly during installation. Closed from the rear very thorough relief corps.
On the front side of the LSi-RTS105 posted two 135-millimeter midwoofers Dynamic Balance of resonance with cast basket and cone "aerated" polypropylene (cone of this stuff gets hard, but easier - winning is 20% compared to conventional polymer and 35% - aluminum cone with the same diameter). Between them with some offset from the axis is embedded 25mm fabric dome tweeter with a ring - its main feature is the minimum frequency response with a small (up to +/- 15 deg.) Away from the axis of the radiation. Inspires respect and workmanship crossover, details of which can be seen through a special window on the front panel. The high class acoustics can be judged by the flatness. Usually for "incorporation" manufacturers do not indicate deviations and Polk Audio ensures that the edges of the range (80 Hz and 26 kHz) decline of no more than 3 dB. Two switches which are visible on the face LSi-RTS105, allow to adjust return to the middle and lower at higher frequencies - need for this can arise when a speaker placed close to the side walls and at an angle to the listening point.
The strongest feature of LSi-RTS105 - tonal balance. Sound system when placed against a wall is very linear, with no roll in high or low area, without noticeable dips and emissions. But balanced sound - not only the quality of the speakers. At an altitude of dynamic and mikrodinamicheskie properties. Speakers are able to create a huge sound pressure and still maintain a relatively high purity and clarity of sound. By the level of sound they also permit hardly anyone lose. Finally, they perfectly fit together with a subwoofer - just configure the system according to the recommendations of THX. I did not have to resort to correction - undyed and natural sound I got when Tweeter selector was set to Normal, and Wall Dist - in > 2. In short, all the formal subjective criteria LSi-RTS105 - round honors. And this, incidentally, is very important. Correct, almost studio sound found in "incorporation" is not so often. If conventional speakers that are not able to show a good side, you can just take if necessary and replace the other, the acoustics, which is already in the wall of the room, this room is much more difficult to crank.
To LSi-RTS105 I had the only one claim. How it is essential - to judge you. In soundstage sources localized shallow and slightly pulled to the emitters. This effect can also try to minimize. First, install acoustic beeper not out as the instructions, and inside - in this mode the center of the panorama focus better. Secondly, if it is possible at the design stage to install speakers in the wall with a slope so that the tweeters were aimed at the listening position, you can not only get rid of the effect of "binding" sources, but also get a more realistic sound transmission atmosphere.
