Very reasonable price, but sounds like some new-fangled power supply, super light weight - wondering if this means performance would be lacking for our purposes and if it really can make it's rated power. Looking at the XLS 1000 or XLS 1500 for a pair of Fi 18's.
Typically class D amps are extremely efficient, with little or no heat, little size and weight due to reduction in heat sinking etc. They've been around a while, but now they're showing up in more and more offerings..., both high end full range apps, sub apps, and pro amps ie Crest, Crown etc..
I think it's a great idea, however I'd like to see them third party verified for LF roll-off characteristics. I'm also curious about the normal class AB/H XLS line (402, 602, 802, 5000), and their LF characteristics as well. The performance is likely fine, but it'd be nice to see third party verification due to product spec embellishment in some of these value priced pieces.
Yes, my thoughts exactly. Well, the guy I'm putting the system in for has decided to go with the XLS 1000, so in a few weeks I'll be able to provide at least initial impressions of it's ability to drive two 15's bridged at 4 ohm, fan noise, thermal performance, etc. Really wanted him to go with the XLS 1500 and run the subs 4 ohm stereo or 8 ohm bridged, but budget was an issue. Therefore, ordering the FI's in 2 ohm and we'll see how it does!
So has anyone used the Crown Class D amps for IBs?
When I built mine, back in '11, went for the Yamaha P3500S amps, as they had a rep for being quiet. They are mounted in a closet, so I don't hear them, no matter what.
Recently I replaced my main L/R speaker's amps for a couple of Crown XLS1500s, set up in mono bridged. No only is the sound quality impressive for a pro amp, the fan in each unit runs VERY quiet. One has to put their ear up to the opening in the rear to hear it. If one could not hide their amp in a closet, I would think this would be the way to go.
The amps are so power efficient that one could just leave it on 24/7, and now worry about any 12v trigger setup.
My daughter and son-in-law just moved into a new house (from a condo), so of course I'm trying to talk him into an IB for the HT system. . Just wonder if the Crown is worthy for IB subwoofers.
