Ascendo and Sutherland AV Marketing Join Kaleidescape as Partners in Bass Hunters

(February 9, 2023) Germany's Ascendo and North American distributor Sutherland AV Marketing are bringing serious low-end muscle to AV NIRVANA's web show, Bass Hunters. The two are joining Kaleidescape as official partners. While Kaleidescape provides access to the purest of movie content analyzed on the show, Ascendo and Sutherland AV Marketing are bringing true subterranean performance to the fold by providing an SMSG32 Infrasonic Subwoofer.

The SMSG32 is a gnarly piece of equipment. Sized at 37.4" W x 21.7" D x 48.8" T and weighing a back-breaking 352-lbs, the sub houses a massive 32" driver with 90mm of linear excursion and a 6,000 Watt amp. Performance-wise, that kind of capability allows the sub to operate at 120dB continuous (122dB peak) with playback reaching a teeth-rattling 7Hz.

According to Ascedo, the SMSG32 can displace "16.6 liters or half a cubic foot, [pushing] as much air per maximum stroke as fifteen standard 18" subwoofers." That allows the sub to reproduce ultra-low frequencies, but also allows it to carry a faster group delay at the same frequencies than the commonly used 18”, 15” and 12" subwoofers in todays home theater and commercial cinema configurations.

Lots of content is planned, including close inspection of films with infrasonic soundtracks, and subwoofer educational videos. So make sure you subscribe to our YouTube Channel!

This is an interesting company as we are still pondering 2 -4 subs to place in the front and back false walls of a room that will be built this summer. The space will be only 17.8 feet long x 11 feet wide.

That's slightly smaller than my space... that said, you won't regret a quad array. As long as you set them up correctly and have each sub individually managed by DSP, your bass experience will be off the charts.

thank you. we still have zero talent for any of that so we've left the space build/setup in the hands of the professionals, (architects, the dealer and their av engineers, and acousticians). we are really only picking the space-appropriate equipment with their help. cheers.

Ascendo is for real. I personally preferred the performance of the Storm/Ascendo room at CEDIA this year to anything else I heard at the show.

Travis, if you listen real hard, I'd bet good money you'll hear a similar performance coming from my house!

Not over the sound of my NextLevel Acoustics Reference Cinema speakers...

That is cool that you are getting one of these!

A 32" woofer has an Sd (surface area of the cone) of ~3675 cm2. The 90 mm of excursion must be both the in/out linear excursion with 45 mm being one way linear excursion. 45 mm one way excursion with an Sd of 3688 cm2 has a displacement of 16.6 liters and matches what Ascendo claims. For comparison, my six 18" subwoofers have a displacement of 26 liters.

Saying that the Ascendo 32" sub can displace "as much air per maximum stroke as fifteen standard 18" subwoofers" means that the "standard" subs must have only 9 mm of linear excursion. This means they are comparing it to a pro audio subwoofer like the B&C 18TBX100 with its 9mm of excursion. Most (all?) of the 18" home theater subwoofers will have a linear excursion that is 2x-4x greater than 9 mm. Many in the systems I calibrate are 34+ mm.

Great math and analysis, Michael! I’m sure there’s some marketing speaking woven in there… what kind of subs do you run?

 

[Michael Boeker]

I have six RTJ Audio 18Subs with three of the 2 x 2400 watt amps.

Individually managed by DSP
I thought the recommendation is to treat them as one virtual subwoofer?

anyway is this now the official Ascendo owners thread?

 

[Todd Anderson]

If you have them spread around a room, then need individual EQ. But, yes, they'll all be fed by the .1 LFE channel.

How do like your Arendal subs, btw? They're GORGEOUS speakers... and the "Avalanche" plate amps carry such an appropriately ferocious name!

 

[Lesmor]

Wow
I will have to update my details that is years out of date, things have changed multipe times
I have had numerous subs but at the moment I have 3 x Arendal 1723 2S subs all EQd as one virtual sub which is why I asked my original question

I just bought a pair of Ascendo CCRM6-P this week but my room is having a revamp so they are still boxed
