Assembly

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.

Inner damping

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.

Extract from STEREO 11/2004

The new VOX 253 development made it necessary to move further up the test scale because it was easily able to overtake the very good VOX 252, which is in normal working use in the editor's office, in a direct comparison, it is clearer, more voluminous and while achieving better separation and, in the bass department, even slightly more efficiently controlled. It is even possible to up the maximum volume level a little. What comes out in the end is an enhanced but equally sophisticated, high-quality audiophile column speaker which is just as applicable to everyday use and is guaranteed to raise the fun stakes. In short, the Vox 253 is now a whole class better, still costs only € 4000 a pair and, as a result, achieves 80 points on the scale. That, in turn, means it gets a fourth star for being excellent value-for-money.
