And with Dirac, the overall performance is way smoother and far more linear. Nice to see they work with a large range of speakers, as assumed- 'without the thumbprint of room acoustics'. (Those 'room' features also look intriguing for apartment owners...)
I need to hear a pair with the R-11 Metas!
… Unlike their other active speakers, their subwoofers are not what I would call a value proposition. They are too expensive for what they’re offering.
Also, without running these through JA test bench, I’m dubious of several things stated in their specifications:
• 500W into a 9 inch woofer? I’d need to see some hard specifications on that because there’s not a 9 inch woofer on the planet that can take 500 W of continuous power.
• Also, those little woofers are flat to 11 Hz? Really? I sincerely doubt that unless of course you’re talking at 80 dB.
• Also, I’d love to see what the distortion is that’s being produced by this sub one is being put under some real stress.
• There are a good number of subwoofers that are half the price that will surpass what this subwoofer can do in the real world. $2000 is way too much to pay for what this subwoofer can give you.
just lol. Btw, one KC92 has the same pistonic radiating area as one JL Audio Fathom f112V2. Won't play as loud but it will actually go a touch lower with *less* distortion. Those JL's have like 2 kW of output power. I have a pair of KC92's (and 62's, which work better with small monitors), Kal is accurate in his evaluation.
The more you know!
The effective radiating area of the KC92 is about 10" pistonic, same as the JL Audio Fathom f112V2 (and the Blade 2 Meta's 4 woofers, which are acutally 5" cones). I have a pair of KC92's (accurate review, btw) and did the measurements and the math.
As far as I know, DL-ART is still in beta for PC.
