I'm still working on it..But yes this thing just pounds. Its very impressive. I have it behind my couch and you can feel everything and it gets so low,most definitely worth the money. It really fills my room now..

Glad to hear i'm not the only one enjoy this sub!!

My initial run of audessey set the sub at +11.... Re-ran audessey this afternoon, and it set the sub to 0 this time.... I went ahead and manually bump it up to +3....

I'm guessing it need to warm-up/break-in for a bit....

Here's a link of an outstanding soundboard recording!! If your a deadhead or a bluegrass fan you'll enjoy!! The stand-up bass sounds awesome!!

I re ran audyssey and it put the sub at. 05. I bump it up more for music. Sounds nice and tight.

What crossover do you guys run your sub at? I go back and forth between 80 and 120 hz.. I'm still in awe how good this thing sounds for music and movies..

I run mine at 100Hz. Yes it's amazing... Usually a ported is good with movies and so so w music. NOT THIS BABY!

I run mine at 80 hz. Any higher and you start to run the risk of making your sub locatable. You don't want to be able to close your eyes and pinpoint where the sub is in a perfect world. Of course however you like it is the best way to run it!

I've tried both 80 and 100, but I'm more partial to the former then the latter. Personal preference more then anything - the XS15 sounded fine either way.

I tried 80,100,120.. Is it me or does 80 sound punchier?

I agree. It also seems more controlled if you ask me.

I just found that I liked the way it sounds and this is with testing it on different kinds of subs

Everyone tells me to put it at 120 or you will lose some bass. To me it sounds like it gets boomier if its as high as 120..

Most expert audiophiles I've talked to recommend 80. I'm sure it's all subjective but I agree with you. 80 just seemed to sound cleaner to my ears.

I have to agree with you 120 seems boomy, but it also depends on your speaker. Set the 15's at 80 and enjoy.

That's what I did.. Reilly is gonna give me a rash.. He is insistent on 120..

I also believe they were insistent that if you used a Y adapter and ran the signal into the left and right input on the sub you would be bypassing the sub's amp and powering the sub with the receivers amp. Stick with 80

Hi all,


There may be two different issues being "cross-talked"..

1)the crossover frequency for any speaker set to small in a receiver's setup menu. This is the frequency at which the receiver will "divide" the bass and send the lower portion to the subwoofer and the upper portion to the speaker. I think there are a couple good block diagrams on this in the FAQ section of this fourm.

Also---remember. This crossover point is not a 'brickwall". That is, it GRADUALLY attenuates the signal. A common slope is 12dB/octave. This means if you set the subwoofer to 80hz (with a 12dB octave filter)....at 160hz(one octave higher) the signal going to the subwoofer will be attenuated 12dB. So at 100hz it won't be attenuated much...3-4dB.

2)The LFE channel itself. I've seen some receiver's that allow the user to select a crossover point for this channel. (they usually offer 80/100/120hz). Since the LFE channel itself is specced 3-120hz I don't see any viable reason to "filter" it so I would set this option to OFF/120hz if you have it available.

That would have been nice if I said that. I said you would be using both the subs driver & the amp with the y connector. Taking away from the amps performance to drive mids & lows.

This is one of the reports that states what I said.

And this was from the above report maybe Tom V can explain what they are taliking about wrong or right

As a side benefit, all a powered subwoofer needs is a single cable connection from a home theater receiver or surround sound preamp/processor line output (also referred to as a subwoofer preamp output). This arrangement takes a lot of the power load away from a receiver and allows the receiver's own amplifiers to power the mid-range and tweeter speakers more easily.

Now if you are running bass management and put your sides, rears, wides or front highs above 80hz where does the bass go if your crossover is set to 80hz on sub? So if you set sides to 100hz and Sub to 80hz any signal between 80hz to 100hz being sent to your sides are lost. I am not twisting your arm to put your sub on 120hz but just stating what happens in bass management.
