The VOX 253 is an upright speaker with its subwoofer TIW 250 XS - 8 Ohm let into the side-wall. This design enables the front panel to be kept very narrow making it that much easier to position. One of the most outstanding features of the TIW 250 XS - 8 Ohm is its unbelievable ability to reproduce the lowest range bass in surprisingly small cabinets. In the listening area, the bass pressure becomes tangible rather than audible, the sort of effect you would normally only expect from much larger speakers. As a result of the side-opening position of the TIW 250 XS - 8 Ohm, the separating frequency between the subwoofer and the mid-range drivers has to be very low. This has been achieved by means of an especially intelligent frequency cross-over design.
In order not to restrict the dynamics at higher bass levels, a bass reflextube with an exceptionally large cross-section and corresponding length has been designed. In this way, flow-related losses are kept to a minimum. The vent is at the bottom in the rear wall so as not to interfere with the attractive appearance of the front face.
This version of the VOX contains the high-end ceramic dome tweeter KE 25 SC - 8 Ohm. An 18 dB high-pass filter produces an optimum phase relationship between tweeter an midrange. This creates an improvement of the clear location of each individual voice or instrument.
