I have XSP-1 with two subs ( left and right ) connected to to it. And I also have denon AVR set as 2.1 channel just for a change. It seems that the low frequency coming from the AVR is much powerful than that of the XSP-1. It has a lot of push and I can feel its strong low frequency rather than that of the XSP-1 even though I play the same song from the same source, the same DAC and the same AMPs. What do you think about it?

I had the same problem, I had to turn the subs volume up all the way and it works fine now

That's what is happening now in my system... Is there any way to turn up the low frequency volume level of XSP-1 like the volume level of the AVR?

how powerful a sub can sound also depends on the point and the slope of the crossover. the same sub can sound differently if you adjust the settings on the back panel or using bass management. if you reduce the point of crossover and use steep crossover settings, the amplifier inside your sub will work less hard because the bandwith it has to work on is more narrow, thus sounds more powerful. the xsp-1 uses 12 db/octave which is shallow slope. with more shallow slope usually (but not always) can integrate better with speakers. my guess is that your avr uses steep crossover 18 or 24 db/octave and lower crossover point.

What should I do then if I want to use the internal amps of my sub so that I can feel its low frequency?

Does it mean that I should turn the low frequency setting on my XPS-1 to 120 so that I can feel its base or use full frequency then adjust the setting on my sub?

yes, if you want your sub sounds more powerful reduce the crossover point in xsp-1 as low as possible but you have to maintain the integration with the speakers. if you cross it too low you will lose some midbass energy. if it's not powerful enough, run the sub full-range and let the crossover setting handled by the sub. although i'm not sure how different crossover slope will blend, eventually you have to setting it by ears in your own room.

I just finished turning the low frequency knab on XSP-1 to 10 o'clock and then putting the sub setting to the max while sub's volume is set to 10 o'clock and it sounds good so far unless you have something else to add or recommend.

Also that it's "bass."

My system sounds great now. I just followed the XSP-1 manual regarding base management and your suggestion too . As the result, it sounds fantastic now.

Rod, you can try these things. You can set the crossover for the bass at 12 o'clock and then increase the bass volume using your subwoofer, this might give you a bit more punch. As for avr. Usually with an AVR, the signal goes through some sort of digital processing first. But the XSP-1 the signal is split via analog means.

You always come to the rescue. Anyway, when you say 'set the crossover at 12 o'clock', does it refer to the crossover of XSP-1? If it does, I think that's what I did and then I also set the low pass frequency on my sub to the max then adjust the volume of my sub to 2 o'clock and the result is really astonishing....

Yeah that's what I mean. Sounds like you did the right thing At my friend's place we had trouble getting a satisfying punch out of the XSP-1 and he turned up the XSP-1 crossover notch to 12 o clock and it fixed it.

What are you guys referring to as far as setting the crossover to 12 o'clock, I am lost evidently

What are you guys referring to as far as setting the crossover to 12 o'clock, I am lost evidently On the rear of the XSP-1 are 2 x potentiometers, one for low pass and one for high pass. Setting them at 12 o'clock means with the slots vertical (the ones in the picture are set at 7 o'clock) I run my L&R speakers full range so the high pass filter isn't used. I run the low pass filter at around 10 o'clock which gives cross over around 70 hz. Cheers Gary

This is a very.... interesting discussion.....
A lot of the suggestions I'm seeing may WORK in certain situations.... but I'm coming to suspect that you guys don't really understand what the knobs do....
First, though, to answer the original question.... The Bass Management on the XSP-1 is better suited to listening to stereo music... the Bass Management on a surround sound pre/pro or AVR is intended for multi-channel. The requirements and capabilities are very different. The Bass Management on the XSP-1 is a simple two-way analog active crossover.... all you can adjust is the cutoff points of the high-pass and low-pass filters. This works well when configuring a "2.1" system.... where the content you're playing is always Stereo (and so never has an LFE channel of its own). The Bass Management on a pre/pro is geared towards surround sound.... - it lets you pick different crossover points for the high-pass filters on each set of channels (fronts, surrounds, etc) - the low pass filters for content from each channel then "track" that channel's high pass filter (you can't set those separately) - the outputs of the low-pass filters from each channel are combined with the signal from the LFE channel and sent to the sub
Now, back to this discussion.......
If you have both filters enabled on the XSP-1, one control adjusts the low-pass frequency, and the other the high-pass frequency. In most situations, if you have filters enabled, BOTH KNOBS SHOULD BE SET TO THE SAME POSITION. Also, in most situations, any crossover frequency setting on the sub should be set to the highest frequency it allows you to set. If there's a switch it should be set to FLAT; if there's a separate FLAT input, you should use it (you want the XSP-1 to be controlling the bass management). The wrong combination of settings will most likely result in a major dip or lump in the frequency response. (The idea is for the crossovers to blend the main speakers and the sub together smoothly.... there should NOT be a lump or dip where them meet.)
Basically, even if it results in a "punchy sound", you really don't want to deliberately pick settings that make a bump because of an overlap. You want to set things correctly.... with the sub merging smoothly with your main speakers.... The LEVEL control on your sub should be set so that you can't hear where the sub blends into the mains... they should belnd smoothly together. THEN, once the frequencies and relative levels are set correctly, go back and boost the level of the sub itself if you want more bass.
If you do it this way, you'll get a "shelving response" where all the bass produced by the sub is boosted by the same amount. (If you do it the other way, you'll probably end up with a "punchy sounding bump", but it will lack the "solidness" you're hoping for. Or you might end up with a dip in the midrange.... which may sound "punchy" but also somewhat odd.... or something else strange. )

been awhile since i looked at this problem.. but i recall i needed to add a y rca jack onto the sub outputs.. or is it the inputs on the sub.. cant remember .. but it really boosted up the power to the sub from xsp-1
the guy at psa subs knows how to boost it up with the y..
