The Ascendo 24″ sub is a monster in size, there is no doubt about that but sound is game changing. Used in conjunction with a a pair of 15″ subs as a minimum the Ascendo bass system re-writes bass performance in our view. We have a good selection of cinema systems running this sub but each one has taken a massive leap forward from an already superb position. Excellent, 10/10 , five stars – just simply amazing. We even have one in store if you want to see the real world size.

The SMSG24 infrasub is a statement.

Its huge cone surface area and huge 90 mm of linear stroke – represents a world record for cinema subwoofers – allow it to move a gigantic volume of 10 litres of air per stroke to pressurize the room. Due to its ultra-low resonance frequency and its sealed enclosure design the group delay is several times faster than the smaller 18″, 15″ or 12″ subwoofers at the same frequency. Also the acoustic power output per cubic inch is by far in favour of this unique design compared to stacked multiple smaller subwoofers.

Its ingenious design allows the SMSG24 to produce frequencies in the infrasonic frequency range with authority, reaching down lower than subwoofers with a smaller diaphragm surface ever will. At the same time this infrasub renders those notes with much more power, structure and resolution. This AIA-developed 62 cm / 24″ super woofer is powered by one of the best high current amplifier designs delivering 6000 watts of power for multiple seconds. Its state-of-the-art DSP control allows to perfectly align the SMSG24 to any existing setup by adjusting crossover, phase and ampliture pesponse.

The SMSG24 ideally suits not only all types and sizes of cinemas, but also high-end stereo systems. Much of the spacial room information of the recording envirnment in a great audiophile recording is contained in the sub 30Hz audio band. You will hear more details in mid and high frequencies.
