Ok thanks N8.. Im really not to crazy with the volume. So I guess I should be fine.

Correct, at-least for the XLS series. I never hears the fan on my 1500s.

Rhed, found this is on Crown's XLS page: Power/Current Draw & Thermal Dissipation

For the 1500's on a 120VAC/60Hz supply (yes?) and condition: "1/8 Power Pink Noise Typical of program material just at clip", 3 x 1500's @ 2Ω/ch load* and 2 x 1500's @ 4Ω/ch load gives a total current draw of 21.6 amps.

If you're simultaneously "just at clip" on the LCR channels with these amps hooked up to the 215RT's, theoretically you're just North of 130dBSPL. eek.gif So, yes I think you will be right at anything less than extreme volumes.

Or... I could have this completely FUBAR as I've never given this much thought; being in a 240VAC country. cool.gif

[* In bridged mode each channel "sees" half the load, correct?]

I've been building best of the best gaming rigs for 10 years now for my friends PC shop in my spare time for display in his store. If you can plug in a TV, you can build a PC, it really is super simple.

N8 thanks. I didn't know you are such a genius computer nerd... haha... I am going to check out the sony 500es and if I don't hear much news about 4k blurays in a few months time I might just buy the 55es instead and wait a couple years. Unless of course if the 500es blows me away with 2k content

Thanks GIEGAR.. I feel more at ease now that I know my one 20amp outlet will be enough.

Give the single 20 a try. I have run multiple subs and sub amps off of single 15 and 20 amp circuits in the past and never tripped a breaker. Of course, you are trending needing even more power (another S2 eek.gif ) so adding a circuit or two wouldn't hurt. wink.gif

Thanks for the link GIEGAR, very strange to see any review (albeit brief) about a JTR product. The irony of this is that if Jeff tricked up the cabinet by adding some bevels, angles, tapers, inlay metal (unobtanium) or ??? he could charge $10K each and still be the best bang for the buck speaker at the show.

But please, nobody tell him ... OK? tongue.gifwink.gif

Fortunately, I gather Jeff would much prefer to spend money/effort on components that would actually improve the SOUND of the loudspeaker (if that's even possible). wink.gif


I'd like to see Jeff in a bigger room next year where he can really "RELEASE THE HOUNDS!".

Nice little and very simple review of the 215's. Yet, very true! I can't wait till next years Axpona. We'll never know what Jeff has up he's sleeve again. smile.gif

I'd be more interested in Class D if they had a 7-channel offering.

I had the SDS-470 for a few months after I got my D-sonic for my upstairs theater. I've since when to only 3 channels upstairs and my denon 4311 is more than enough and I ended up selling it. It was a great amp, I actually wish I still had it.

It worked great but I was thinking that I would need a fan for air flow. So I ran music really loud for about half an hour and the Sunfire was barely warm. Actually my UMC-1 was a little warmer than the Sunfire and it is only a pre-amp, no amp section!

Great amp. I have seen reports on the TGA-5401 (same amp design except with 5 channels) that when driving two channels it can hit 600watts for each @ 4 ohms. I doubt it will hit 800X7 but still very powerful and cool running. I bet it will do pretty well on the 215RT and RM's.


Actually, the 7401 is only 800 watts for front stage channels, the other 4 channels are just 400 watts per 2 channels. It is a little deceptive how the ratings are worded, but that is in fact accurate/.

Not sure where you got your info but if you look at the 7401 specifications on the Sunfire Website, it unambiguously shows all 7 amp channels outputting the same WPC. confused.gif

Would probably sell...I should buy some iNuke and put in big black boxes with 3/4" aluminum face and sell for $20,000 to power the fancied up JTRs. :-D

That's bad Coach. Just cause you still have your 212s for sale doesn't mean you should come on here depressed. You could lose your man card for comments like that.
