SUB T-25.50

For the high-end TIW 250 XS - 8 Ohm woofer we recommend one of two cabinet sizes: either a small, space saving version with a net volume of 30 litres (SUB T-25.30) or a somewhat larger version with 50 litres net volume and a lower tuning (SUB T-25.50).

As one would expect, the SUB T-25.50 provides warmer, deeper bass, and the lower limiting frequency is 25 Hz, considerably lower than for the SUB T-25.30. But it is particularly in smaller rooms that the 30 litre version comes into its own. The missing low-bass (approx. 3 dB at 35 Hz) can easily be compensated for by applying a little electronic bass boost. Of course, the maximum volume level will be slightly lower as a result.
