Subwoofer M&K Sound MX 250
In more detail acquaintance found that internal space subwoofer actually divided into two parts - the lower recess is one of a 12-inch dynamic heads whose radiation is directed into the upper chamber, which, in turn, is mounted to the second speaker similarly sized radiating outwardly. Thus both the driver operates on the total volume of phase. Hence the name of this scheme - push-pull. This specific speaker placement explains the considerable height of the housing MK Sound MX250.
Black finish cabinet is very ascetic and the entire facade pulled into the grill cloth on a rigid base of MDF. Of course, the piano lacquer would look much more impressive - and at the same time would affect the value of the unit; moreover, in the dark cinema evaluate the cabinet finish is very difficult acoustics. So in this case should reassure that every ruble spent here on the sound. Complete with a subwoofer are rubber feet, instead of which you can optionally choose the threaded studs of the necessary size. Such a measure will improve the isolation unit to the floor, which has a beneficial effect on the sound. On the back of the stand, a large finned heat sink output stages of amplification and switching panel, offering a variety of options for the integration of the bass module to the system. Four pairs of luxury acoustic terminals allow the use of the subwoofer crossover to separate areas of responsibility c pair of main speakers connected directly to the output of the power amplifiers. Two pairs of RCA connectors help to implement a similar approach, but in terms of outputs signals with preamplification. Smoothly regulated not only the volume and crossover frequency, but also the phase. For realization of the LFE, when control low-frequency signal is transmitted fully AV-receiver, no special measures not provided - you just need to bring control of the cutoff frequency of the filter to the end position and use a low-level input. Amplification path, equipped with a proprietary system Headroom Maximizer IV, develops 250 watts and loaded into two 12-inch head.
When initially setting up the surround sound algorithm for the automatic calibration of our receiver set for MK Sound MX250 level of -6 dB. During testing, we decided to pick it up to -3 dB for greater impact in the low register subwoofer.
The device gives a very thorough and fast bass. Push-pull scheme allows you to connect the advantages and disadvantages of reverse the acoustic design with bass reflex port and enclosure. Instant return, firmness and composure response are combined in this subwoofer with a coherent study of sufficiently low frequencies. The machine will adequately assess their capabilities and not trying to dive deeper, resulting in a complete lack of distortion, porridge and buzz at the bottom of the operating range. Performed well and subwoofer as part 2.1 system.
