Hey guys, long time lurker first time poster. Looking at doing a dual DIY setup of 2 ultimate 15s. Did some research. Looking at getting 2 xls 1000 to power each sub. How are these amps?

Thanks

That's the exact setup that I'm looking at. I have not used the amps so I can't comment on how they perform.

Ok cool. You mentioned you have 2 of these amps already? You haven't tried them yet? Essentially I want to know if they are reliable and out put all the power properly and if they have any limitations or anything. I was reading about some amps and after a certain frequency they lose power or something like that.

I don't have them in my possession yet. Hopefully they'll come in soon.

I have an XLS1000 and used it for a year. It is a fantastic amp with bags of clean power. HPF is a lil higher @ 50Hz, which practically renders it useless unless it is powering sealed subs or assisted by outboard dsp if used for a ported sub.

FWIW, it offers stronger chest slam than iNuke at equal output. I used it in bridged mono.

I use a XLS1000 with a 15" DIY Ultimax and it is awesome. Not quite as refined as my SVS SB13-Ultra, but it really rocks the house.

I set the peak limiter at 1100 watts on iNuke 6000 dsp and also set crown xls1000 in bridged mono which is 1100 watts. So with equal output, crown had stronger 25-35hz impact than iNuke.

Crown xls1000 has been tested by somebody to over achieve the stated specs. I read a review on amazon probably a year or so ago.

Is that 50hz high pass filter on the XLS-1000 able to be defeated? If not, then I would guess this to be a very poor sub amp.

Yes, its defeated very easily using a menu on the front panel (no dip switches). I have one and I'm a big fan: mine runs a 2 ohm load for hours without the fans running hard.

That seems quite odd.


Oh, and BTW, the 50Hz HPF is for the tops, not the bins.

Two would seem to be two too many to me too.

IMO I would suggest looking to spend just shade more and going for the xls1500 or higher. The xls1000 has a weaker power supply and components. Bumping up to the 1500 gives you a little more power, and better build quality. Not to say the xls1000 is bad, just moving up to the xls1500 or more is well worth the extra coin. I have experience with both the 1500 and 2000 and They are awesome little amps. The blue LED display can be a bit bright, but just go get some 3m window tint from Lowes or HD and the problem is fixed smile.gif

FWIW the 50hz HPF is something that neither you nor the second poster would be concerned about with using them for sub duty. This statement:

"HPF is a lil higher @ 50Hz, which practically renders it useless unless it is powering sealed subs or assisted by outboard dsp if used for a ported sub."

is not accurate. The XLS series is perfectly capable of running any type of sub, or mains speaker for that matter. The 50hz being a "lil" higher at 50hz is meaningless, since it is entirely selectable and defeatable.

Scll, where are you in NC? If you want to hear an xls1500 we can arrange a meet-up. I am in Asheville.

I'm near Boone. Do you think that the 1500 will be too much for the 15" Ultimax?

Sorry if I my statement conveyed opposite meaning when I said 50Hz HPF is a lil higher. What I actually meant was that the lowest HPF that can be set on XLS 1000 is 50Hz. I have this amp and I was using it on a DIY mid bass module setting the HPF at 50Hz. Of course one can defeat the HPF. It is just that if somebody has a ported sub tuned to anything lower than 50Hz, he will have to use an external DSP to keep the driver from bottoming out if you use this amp all barriers open.

Here is the link to the review I was talking about, though this guy tested it at 8 ohms but still one can deduce the performance at 4 ohms bridged mono;

Good amp, power is true to advertised specs
