Beskrivelse

NB! CRMS-systemet ble nylig installert i screening-salen hos Norsk Filminstitutt i Oslo (NFI), les gjerne hvilken respons som ble gitt på denne installasjonen i denne artikkelen: http://www.alconsaudio.com/site/news_item.php?news=77.

Kraftig 18" subwoofer fra Alcons Audio som er spesielt tilpasset plassering bak lydtransparente lerretsduker. Dette er en passiv subwoofer, og selges kun sammen med Alcons egne forsterkere.

CB181sl ultra-slim deep-tuned 1x 18" bass system. 4" voice- coil high-power 18" driver. NL-4 connection on cabinet side for placement against walls. Flown or stacked with 10.8"/27.5cm depth.

  • single 18” long-excursion woofer with vented-spider
  • space-economic design: cabinet depth only 11”/27.5cm
  • lowest usable frequency 25Hz.
  • power handling 1.000W RMS, 6.000W peak
  • SIS pre-wired for very high damping and speaker cable compensation (with ALC)
  • large, side-placed vents for improved flow capacity without moving the screen
  • dedicated (excursion) protection in combination with SDP modules (with ALC)

The CB181sl is a direct-radiating, ultra-slim subwoofer system for cinema applications. Featuring a single 18” long excursion woofer with 4” voicecoil, together with the large bass-reflex vents, the CB181 delivers sustained, fundamental sub-bass output.

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the CB181sl and ALC controller-amplifier. Especially with the typical long speaker cables and the subwoofer system’s possible low impedance, the effect of Signal Integrity Sensing is remarkable;
Really tight and accurate reproduction for even the lowest octaves.
The enclosure design provides for stacking, flying or wall-mounting. The side-oriented reflex vent enables the cabinet to be closely mounted behind the screen without chance of screen resonance. Typical applications for the CB181sl include cinema subwoofer or sub-bass extension of general sound systems, used in multiples depending of low frequency requirements.

For full system performance, we recommend using the CB181sl in combination with an ALC amplifier/ controller. Driven by the ALC, the CB181sl not only delivers maximum sound quality and output power, but is also inaudibly protected against over- excursion (SDP circuit), which is a typical challenge for cinema subwoofer systems.
