High-performance - infrasonic subwoofer re-defined

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 pressurise 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 ASC-24SPAS 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 ASC-24SPAS to any existing setup by adjusting crossover, phase and amplitude response.

The ASC-24SPAS 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 environment in a great audiophile recording is contained in the sub 30Hz audio band. You will hear more details in mid and high frequencies.


ASC-24SPAS - more bass pressure, depth, structure, attack, imaging equals more enjoyment.

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.
