How to evaluate the POLK AUDIO Custom Series
Before receiving the POLK AUDIO 5.1.2 of Ni, we have been evaluated for the Signature series, LSIM series, or even the flagship Legend series, etc., not only evaluate the front, but also evaluate the front, but also "The American style of the style" is impressed. As an internationally renowned American audio brand, POLK AUDIO has a full set of technical processes in speaker box, unit design and production, and has a number of patented technologies, but the price is relatively close, so there is a high sales in many regions. The custom installation series of this item is included in three 265-RT into the wall speaker, two 65-RT into the wall speaker and two 80F / X-RT Tianhua speakers, plus a 12-inch subwoofer HTS12, just Make up a set of 5.1.2 custom installation systems.
Diverse style, flexible installation
Adapted to various decoration style
First, introduce the basic cases of the three walls of the wall speakers from 265-RT, 65-RT, and 80 F / X-RT. Among them, the highest-specific 265-RT is a three-degree structure, configured 1 1 inch annulus trowndo unit and two 5.25 inches in bass units, and the panel is at least inverted by Power Port. There are also two buttons, one of which is the distance switching switch and the other is the room reflection attenuation switch. According to the official statement, if the space size is limited, the position of the speaker mounted and the distance between the side walls is less than 60 cm, then the lateral reflection sound of the 50-200 Hz frequency response may cause the bass to cloudy. At this time, press "Distance Switch", which can make the frequency response by adjusting the frequency response to gently, eliminate the buzz, while retaining the frequency response of the ultra-low frequency band. In this way, the installation of the speaker can be more free and flexible. Another "room reflective attenuation switch" is to reduce the volume of 4-5 kHz high frequency to reduce the influence of reflection, and the high-frequency response of the 1kHz band is retained to show the details of the treble.
Two 65-RTs are two-degree frequency structure, configured 1 1 inch trowndo unit and 1 6.5 inches in bass units. In addition, there are two 80 f / x-RTs used by the sky spendling, each of which is equipped with an 8-inch bass unit and two 0.75-inch treble units, and designed special structures, so that two treble cells can Voice towards different directions and enhance high frequency extension.
In addition to these three models, it can be seen from the official website that there is a variety of wall-type speakers with different unit configurations and specifications, which are equipped with a large SHEER-GRILLE adsorption mesh cover. After installation, only 7mm higher than the wall, which can be painted with the mesh to match the decorative style, so that users "hide" to create a completely invisible home audio system, or do not occupy more space Premise the existing sound system to meet the diversified needs. There is no doubt that the custom installation series is already a very perfect product line of POLKAUDIO, which is the main reason for this product line.
80 F / X-RT is designed with a special structure, allowing two treble units to vocal in different directions and enhance high frequency extension
If you are installed according to standard
Can present a very fine sound style
In the introduction of the official website, 265-RT is generally used as a medium speaker, but considers three 265-RT and two 65-RT this time, let 265-RT act as the front left right speaker, 65- RT acts as a surround speaker is relatively appropriate. Although the magazine does not install the condition of the wall speaker, in order to actually experience the sound performance of this set of speakers, we still want to let them stand on the desktop and audio racks like ordinary speakers. Maybe you see this kind of action will have a curious, this sound will sound? Objective, there is a good or bad. No wall means that there is no limit, do not consider the problem of tract or box resonance, but the medium and low frequency part may be so thick.
Before actually listening, I also worried that the angle between the front left and right speakers and listening positions is relatively small because of the restriction of the placement position, which may cause the problem of narrow sound field. As a result, there is no wall to some extent, and then Plus the booster HTS 12 booster, eventually creating a fairly wide sound field, the details of the medium and high-tone and penetration are also possible. Although in the 60 square meters of audio-visual rooms, the 265-RT of the wall is not slightly short-lived, but the wall speaker is definitely to enter the wall installation to show the real level. Take 265-RT as an example, the officially recommended opening size is probably 49 × 19cm (high × width), and the installation depth is 7.8cm. If the standard is installed in accordance with the specifications given, then the frequency of the 265-RT ranges can override 30Hz-27kHz. Similarly, the frequency of 65-RT can also reach 32 Hz-27kHz.
65-RT configured 1 inch anniode graphic trowndon and 6.5 inches in subwoofer
Patent Power Port Bass Diversion Technology
Implement better bass effect
It is said that the HTS 12 subwoofer is no longer the first time to come to our magazine, and the speakers have been used in the other series of speakers before POLKAUDIO. It has a built-in 12-inch long stroke unit, although the power amplifier power is not large, but benefited from POLK Audio patented PowerPort bass passage, can extend the entire low frequency inverted phase hole, increase the surface area, minimize turbulence, distortion and Inverting the hole noise, smoothly introducing the air air of the speaker into the listening area to achieve better bass effect. Therefore, HTS 12 has a good performance in two aspects of low frequency and strength. For example, when playing "Silver Wings Killer 2049", you will feel that it makes the sound of the sound and the immersion feeling of the sound, play When the gun battle of "Speed Special Attack 3", the slammed guns appeared to be more powerful, and the stimulus of the scene was now coming. When the songs such as the "King of Circus", it allows drums to bounce out from a musical instrument sound, enhance the rhythm and atmosphere. In general, personal feelings HTS 12 is a high price / high premium.
