Characteristics and sound properties
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 reflex tube 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.
The only difference between VOX 253 and VOX 252 is the new woofer TIW 250 XS 8 Ohm. A change of the crossover was not necessary.
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.
In the lower part of the cabinet, you can see the tunnel, made up of the base and an upper board. In the middle, there are three cross-reinforcements. At the top of the cabinet, behind the cut-out in the baffle for the mid- to high-range unit, is the enclosure required for the mid-range cone, made up of two wooden boards. Three 8 mm holes has to be drilled into the rear board of the mid-range enclosure for the connection leads. These holes have to be sealed well. Fitting the TIW 250 XS into the side is a special feature. The mounting board for the TIW 250 XS (346 x 297 with a 235 mm cut-out) itself is glued in place from inside behind the round cut-outs in the corresponding side panel. This means that the bass driver can be sunken by 19 mm (19 mm = thickness of the boards). For optical reasons the side panel cut-out must be made extremely accurately. The crossover unit is mounted on the side panel behind the bass port.
The damping uses one mat placed in the medium range cabinet. The remainder is evenly distributed throughout the cabinet. The area above the tunnel opening (at the rear of the front panel) up to the lower edge of the reinforcement remains free. If, as a result of the acoustics in the room, the low-range bass is too powerful, damping this area will have a corresponding effect on the overall bass output level.
