Crown XLS- for the rest of us!

Change to the Audience Power Chord gave some improvements including to the treble. Things felt a bit more fleshed out, fuller with the Audience.

Then it was time to go monoblocks! And whaddya know. Improvements! In the impact of the bass in particular. As those of you who are familiar with SP Tech speakers know, they are known to benefit from gobs of power. And yep. Bass was fuller with greater detail and impact.

As for the rest of the frequency range, monos give a greater sense of ease.

So did the lights in Chicago dim when you hooked up the monos? That is 1550 wpc into a 4 ohm load.

new mandatory mood lighting for the neighbors.

Hope no one needs to use their microwave. Because all the juice is mine!

Now let's see how the monos do at low volumes.

Take pictures when the cops show up! wish I could have arranged a way to swing by hear the new speakers but this week has been rough. Looking forward to when my biggest concern involves amps and cables, magic pucks and cryo treatment.

Would ERS Cloth help a digital amp?

roscoeiii · « **Reply #547 on:** 8 Dec 2014, 04:26 am »

Oh wow. The power! At low volumes this seems to be translating into great bass impact and detail that I wouldn't expect at such volumes. May have something to do with these speakers being transmission line (from something I read somewhere) . But not sure.

Did you ever find out the impedance and sensitivity of your new speakers?

roscoeiii · « **Reply #549 on:** 8 Dec 2014, 04:37 am »

Didn't get those details. But they are likely close to that of the Continuums which are identical except for the bass not being transmission line. Here are the specs from a review of the Continuums:

Frequency Response: 25Hz - 24kHz +/- 2dB (typically +/- 1dB) -3dB @ 25Hz & 30kHz

Phase response: Less than 360° from 100Hz - 20kHz

Group Delay Response: Less than 1 mS delay shift from 100Hz - 20kHz

Directivity: 90° Horizontal x 30° Vertical from 900Hz - 10kHz.

Peak Power Handling: Greater than 1000 watts (10mS)

Short Term Power Handling: 600 watts (I.E.C. 268-5)

Long Term Handling: 250 watts (I.E.C. 268-5)

Sensitivity: 91dB SPL @ 2.83V /1-Meter, 88dB SPL @ 1-watt/1-Meter

Impedance: 4-ohms (nominal) - 3.2-ohms (minimum)

Crossover: 4th order symmetrical, in phase Linkwitz-Riley @ 750Hz.

Power Requirements: 50 watts RMS/Channel (200 - 750 WRMS/Ch. preferred)

Horizontal Dispersion: +/- 45° - 600Hz to beyond 10kHz (standard -6dB Beamwidth Limits)

Vertical Dispersion: +/- 15° - 600Hz to beyond 10kHz
(standard -6dB Beamwidth Limits)

Low Frequency Driver: (2) - 8" Aluminum Cones w/Phase Plug & Cast Magnesium Frame

High Frequency Driver: Waveguide Loaded 1" Textile Dome - Ferrofluid Cooled

Nice!

I'm glad it's not just me liking these crown xls 1500's in bridged mode anymore!

roscoeiii · « **Reply #551 on:** 8 Dec 2014, 05:16 am »

Attention XLS folks!!! Not sure for how long, but Amazon has the XLS2000 for 17% off their normal price. So you can get the 2000 for around the price of the 1500, at $356 shipped. Sadly, limit of 1 per customer, for those of you inspired by my recent monoblock comments.

Amazon changed the price. The deal is over.

a.wayne · « **Reply #553 on:** 8 Dec 2014, 02:33 pm »

Roscoe ,

It would be great to compare MONO setup to Jack 's NCores , also easy to tell the cryo amp its the one with the .5" shrinkage ....

roscoeiii · « **Reply #554 on:** 8 Dec 2014, 02:48 pm »

That'll depend on Jack's schedule and I know he has been slammed lately.

steve f · « **Reply #555 on:** 8 Dec 2014, 09:47 pm »

The Amazon deal is back up...sort of. Discount is 15% no longer 17%.

Nope it's a scam. I tried to run it but doesn't provide a good deal.

Tomy2Tone · « **Reply #556 on:** 8 Dec 2014, 09:54 pm »

Ma,Ma,Ma, My Pomona!

Just got the Pomona binding posts installed in my crown monos and I have to agree with DaveC113, an improvement indeed. Not bad for $50.

Did you have to file any of the posts tomy2? Mine will be here tomorrow.

No, it was close on the positive post for the right channel butting up next to that little black box. I thought about hacking the end off but it seemed really secure so I just went with it.

I think they definitely improve the sound, a little cleaner and smoother.

I also ran it and the final price is $373.39. That is a heck of a deal for a new 2000.
