This subwoofer cabinet was equipped with two bass drivers, placed symmetrically opposite one another, practically an impulse compensated system (see also Hexagon by Bernd Timmermanns).
The titanium midrange / bass driver and the MHT magnetostat are located - as in the original VOX 253 MIT - in the upper part of the much slimmer cabinet.
The VOX 253 MTI Ladylike shows the following characteristics:
Technical data:
The kit Order No. V-5987, Price per pair (without cabinet) EUR 2602,90 excl. VAT: € 2187.31 / $ 2384.17
For a separate Subwoofer the crossover has to be changed: the two bass coils have to be exchanged for two 4.7 coils. We recommend the Mundorf i-core BS-core coil with 6.8 mH, of which 2 are needed: EUR 58,70 excl. VAT: € 49.33 / $ 53.77
Additionally you need loudspeaker cable (to connect the subwoofer) and bi-wiring terminals (e.g.: T122/96 MS Au), of which you need 3: EUR 10,00 excl. VAT: € 8.40 / $ 9.16
- the 8 drivers (2x MHT 12, 4x TI 100, 2x TIW 250 XS), - 5 bi-wiring terminals (one for each satellite, 3 for the subwoofer for connecting the satellites and the amplifier) - 15 metre cable Inakustik Premium LS Silver (silver plated) - PAN and Allen screws 5x30 - 8 Pack / 16 mats damping material - sealing tape - the crossover components described below - the building instruction
Kit price for 2 satellites and subwoofer, with gold plated terminals and silver plated cable without cabinet: EUR 2914,00 excl. VAT: € 2448.74 / $ 2669.13
The crossovers components that need to be mounted on 2 universal PCB (one for left, one for right) are as follows (per stereo channel): - 2 x universal PCB's 205x140 mm for wiring up components
for MHT 12 magnetostat: - Mundorf MKP Supreme 3.3 μF / 800 V - baked varnish air core coil 0.47 mH / 0.41 Ohm - Mundorf MKP capacitor 6.8 μF / 400 V - MOX10 1.5 Ohm/10Watt (brown-green-gold) - MOX10 8.2 Ohm/10Watt (grey-red-gold)
for TI 100 midrange drivers: - MKP capacitor 100uF / 400V, improving transparency. - 2 x MOX10 4.7 Ohm (yellow-purple-gold) in parallel, instead of single 2.2 Ohm, since the 2.2 Ohm would get extremely hot already at 10 Watt per driver. - H core coil 3.3 mH (a 2 mm air core coil would be even better ) - MKP capacitor 68uF / 400V, improving transparency. - baked varnish air core coil 0.82 mH / 0.54 Ohm - Mundorf MKP capacitor 0.47 μF / 630 V instead of 2 x ELCO special, resulting in a dramatic sound improvement. - Mundorf MKP capacitor 6.8 μF / 400 V - baked varnish air core coil 0.33 mH / 0.26 Ohm - 0.5 mm ferrite core coil 10 mH / 3.48 Ohm (for resonance suppression) - Mundorf, 150 μF/63 V, ELCO etched (for resonance suppression)
for the bass driver, where quality is less critical: - Mundorf H125-core coil with 6.8 mH - ELCO, non-etched 100uF/ 35Volt - ELCO, non-etched 33uF / 50Volt - ELCO, non-etched 47uF / 50Volt - MOX10 resistor, 6.8 Ohm (blue-grey-gold) - 0.6 mm ferrite core coil 22 mH / 4.26 Ohm - Mundorf, 330 μF/63 V, ELCO etched - MOX10 4.7 Ohm (yellow-purple-gold) Please note: a 4.7 Ohm instead of 3.3 Ohm should be used, since the coil has less resistance.
