B&W ASW CDM 1000 watt klasse D,32,5kg.UK Made,izgst,serviced

The ASW CDM combines a sophisticated 300mm (12 in) driver and 1kW ampilfier.
With styling to match the CDM NT range and available in the same finishes it
complements any CDM installation.
This versatile subwoofer is compact enough not to physically dominate the smaller
room, but powerful enough to fill the larger room with powerful, deep bass from
either music or movie based sources.
The rugged 300mm (12 in) driver, with its composite paper-Kevlar® cone, large
magnet and high-power voice coil, can move large volumes of air with exquisite
control for accurate low-frequency output.
To ensure the driver can perform in the relatively compact cabinet, the subwoofer
features a powerful 1kW amplifier to apply the necessary equalisation. Equipped
with audiophile full-range Class-D circuitry and a switch mode power supply, the
amplifier is extremely efficient and operates reliably cool

Binnenin de nieuwe B&W subwoofer, de ASW-CDM, zit onder andere een 1000 Watt versterker ontworpen door Philips. Daarnaast produceert de subwoofer een bass geluid vanaf 15 Hz mede door een diagram dat is gemaakt van het door B&W zelf ontwikkelde geweven Kevlar materiaal. Het kabinet is verkrijgbaar in een selectie van met de hand afgewerkte houten afwerkingen.
De nieuwe B&W is gemaakt voor toepassingen in diverse opstellingen. De gebruikte filters kunnen bijvoorbeeld direct werken voor gebruik met een AV versterker/processor of op een speciale manier voor gebruik in een twee kanaals systeem waar de crossover van de subwoofer van belang is. Ook is er een Link Out uitgang die het signaal door kan geven aan een tweede (of nog meer) subwoofer, wat handig is in zeer grote ruimtes.
The B&W ASW CDM is a very sturdy (72 pounds/32 kg) sealed subwoofer with a 1,000 watt amplifier. It doesn't mess around; it has enormous output and decent response right down to subsonics. This is not some lightweight offshored vented-box imitation; this is the real thing.
It sounds great, pumping out loads of deep clean bass where few subwoofers can.
It has same performance as the ASW800 subwoofer, but in a simpler and therefore less expensive conventional cubical cabinet. It actually has about the same response as the awesome 15" ASW850 and ASW855, but with less maximum output.
The ASW CDM goes an octave below what most other common "subwoofers" can reproduce.
The bass is half the music, so especially if you've only got wimpy speakers like the B&W 805, you need a pair of woofers like this.
The B&W ASW CDM is styled to match the CDM1 speakers.
The ASW CDM has no resonances and just thuds where it needs to, never adding its own coloration or changing the pitch.
I prefer crossing this woofer in below 40 Hz to reproduce only the lowest bass when used with with decent full-range speakers like the B&W 802. For the ASW CDM, bass guitars are trivial; standard 4-string bass guitars and stand-up basses don't even play as deeply as 40 Hz; the ASW CDM kicks in and gets busy below where the basses usually stop!
The ASW CDM is built like a tank. Its solid sides don't vibrate at all to the touch when the woofer cone is moving a half-inch or more in and out.
The woofer cone looks like paper, but it's actually paper and Kevlar. It feels more like thick cardboard or a thin sheet of wood veneer than just paper.
The 1,000 watt amplifier is silent; there's no buzz or hiss even if you stick your head to the woofer cone.
