VOX 253 MHT

Characteristics and sound properties

Due to the deep starting frequency of the MHT 12 - 8 Ohm it is possible to make use of this magnetostat in the VOX 253. Of course, the crossoverhas to be changed from that used in the original version with its KE 25 SC - 8 Ohm. Fortunately, the AL 130 - 8 Ohm 's only have to be separated slightly higher which means we are still a long way from the baffleresonance levels. Here, too, the transfer frequency is 3000 Hz. As can be seen from the dotted frequency curves for the individual drivers, the AL 130 - 8 Ohm drop off at 2000 Hz and the MHT 12 - 8 Ohm at 4500 Hz and meet again at 3000 Hz and -6 dB. The magnetostat need not by any means produce its full output at 3000 Hz, as some people often believe. This would not make sense in terms of achieving the lowest possible distortion factor.

Since the front panel of the MHT 12 - 8 Ohm is slightly larger, the AL 130 - 8 Ohm 's have to be spaced a little further apart (10 mm).

As regards their sound quality, both versions (original VOX 253 with KE 25 SC - 8 Ohm and VOX 253 MHT) are at the same high level. The version preferred by each particular customer will depend on personal taste, the type of music you listen to and how you listen.
