I have the Revel Subwoofer/AMP at home.(LE-1 - SUB-15)
My question is this;
Should I use the LE-1 AMP's crossover, or my pre amplifier (Proceed PAV/PDSD) ?
I have always thought this was "the right" sollution;
All speakers set to cuyt off (80hz or less) and everything below to the sub.
I haven't tested anything else - but...
5.1. If I use the crossover in the LE-1 AMP the 5.1 will be mixed to 5.0.
Then the crossover shall take bass out of the front speakers. What happens to the bass in the other speakers then ?
Normally I would have configured the bass using the cross over in the pre amp, but - the user guide of the Revel
sub says the best way is to use the Revel amps cross over...
I've always used by AVP as the crossover with good results. The LE-1 sounds good, and has tremendous stability and power, but I would personally just use it as an amp. I like the AVP since it gives you variablity in the crossover range. If you use 80hz only, then I would guess the answer of being personal preference as to which you think sounds better. Both are very good!
You might look at www.revelspeakers.com and see stereophile reviews. I believe there are a couple of reviews relating to the Sub woofer. I would use the crossover from the AVP which I think will be cleaner and involves less cables.
The connection b/t the LE-1 and AVP doesn't require a Y-connection, and for best results, get a balanced cable.[/b][/quote]
In the users manual of the Revel SUB side 19 there is explained the connection when using the pre AMPs crossover.
(Not preferred - according to the manual...)
It states that the connection should be from the sub output into 2 inputs of the LE-1 amp... ???
I have a balanced cable bythe way. The Proceed PDSD have a balanced out for the sub...

Both the AVP and the PAV will support a split of the sub out. Get a good quality split, I do not use a wire split I use Puresonic gold plated hard split and works great.
Since i also have 2 SUBS, I have recently played with my cross overs and found a real clean setting. Obviously different gear may resul in different results but set all speakers crossed at 50hz or 60hz and set them to small. I found a cleaner mid and a faster, more balanced (tone wise) lows.
...It simply amazes me how much time I can spend on my setup...now I have a free Saturday morning...hummm what to do ??..oh yeah, SPL measuments...yeah !

Thanx for the tip.....
The best thing would the be this; put a split on the mono out on the pre-amp, and 2 cables to the LE-1 amp. Right ?
Should be fun testing this. I have had the SUB-15 for some time now, but I have never tested it together with the LE-1.
Hi-Fi is fun!
Another strange (?) thing in the manual; they (Revel) says that the best is to place the sub in the corner. From a lot of others there are different oppinions (more to the middle - out from the wall).
Have you or any other tested this ?
There are some room correction stuff on the LE-1 - maybe they can be of help....
I have yet to see an XLR split, it may exist but i have never seen one..
I know for a fact that the PAV/AVP outs (RCA) for subs are of excellent quality and that the only difference that you would see using blaanced XLR cable is that your AMP is 10meters or more away. this is when XLR cables accelerate compared to RCA interconnects.
I would use a good quality RCA interconnect if possible.. if distance is an issue..continue your search for a balanced XLR (and let us know !!)
As for position.. play around, if you have 2 subs, the "prefered" way is both in the same corner. Corner positioning will provide you better /stronger lows. move them out if too much.
I have my dual subs (SVS 20-16c) in a left right configuration. The AVP supports Stereo subs where cross over lows are split by left and right. not noticable in music but in movies. I hear the difference !!
