I have the HK AVR 630. There is no crossover setting for the sub. There are four independent crossover groups just as you would expect: fronts, center, surrounds and surround back.
In response to this thread, as well as stated numerous times, just crank the crossover knob directly on your sub all the way up. Then let your receiver control the crossover settings and what sounds are sent to your sub.

Agreed (I also have a 630), but there are some settings which a reasonable person might *think* adjust the "crossover for the sub".
M60ti, VP180, QS8, M2ti, EP500, PC-Plus 20-39
M5HP, M40ti, Sierra-1
LFR1100 active, ADA1500-4 and -8

Randy, this might not be what Josh is referring to, but what's come up in some previous threads is what John B. described: the HKs have a separate provision for rolling off only the LFE channel to the sub(this doesn't affect the regular crossover setting or settings that establish crossovers between the speakers and sub). The LFE channel which occasionally has special low frequency effects during movies theoretically extends to 120Hz, but in practice there's almost no content above about 80Hz. It's been said that allowing the sub to receive the full 120Hz LFE range might let in some noise above 80Hz where there's no useful content. So HK(instead of simply setting a 80Hz LFE lowpass)gives the user an option as to where the LFE channel to the sub will be filtered.

Here's something else to try out. On your HK receiver, set the sub output to +12db and the sub volume at the 9 o'clock setting. See if that takes care of the rattle. You might get too much bass, but since you like low frequency sounds, that shouldn't be a problem!
Hm... worth a shot. What is your theory here? 
Josh
Well...the theory (ahem!) is that the sub gets a stronger input signal and does not have to work as hard to amplify the low frequency sounds...

Richie, your suggestion(raising the voltage output to the sub amp from the receiver and lowering the level control on the sub itself to compensate)is a good one to put more voltage into the sub amp to keep it "awake". So far as the actual driver in the sub rattling, etc. on very high levels, that wouldn't appear to be affected since it's a mechanical, rather than electronic, problem.

I recieved this in my post about two better than one sub
John (not sure of his last name) on this board has done numerous experiments with Axiom subs.
2 EP500s are better than 1 EP600 for better distribution of LFE in the room.
EDIT:
Found the post from Jakeman:
1. 4 ep600s
2. 3 ep600s and 1 ep500
3. 2 ep600s and 2 ep500s
4. 1 ep600 and 3 ep500s
5. 4 ep500s
6. 3 ep 600s
7. 2 ep 600s and 1 ep 500
8. 1 ep600 and 2 ep500s
9. 3 ep500s
10. 2 ep600s
11. 1 ep600 and 1 ep500
12. 2 ep500s
13. 1 ep600
14. 1 ep 500

I've decided to take the advice, stop tweaking the 350 and order a 500. Now i'm waiting, :-)!
On a side note. All this staring at the Axiomaudio.com site has sparked my interest in ordering a set of M80's as well. I'm crazy. I looked at the connection photo on the details page. There seems to be 2 sets of input? How come this is so? And how would you take advantage of them?

2 sets up plugs are for bi-wiring and bi-amping as illustrated below:

Josh, don't rule out the m50 or m60's either. I have the m60's and your aware they are in a huge room, and they have no problems, the bass is killer. They also have the extra terminal, but just leave the gold clip in place which keeps them as one and just use 12 or 14 gauge wire. In my opinion, bi wiring is over rated. Bi amping is a different animal, and has it uses. I don't think you listen to music at insane volumes anyway.

The only reason I'm ruling them out is because of the future upgraditis I may encounter. If I can convince the wife this weekend during a candlelit dinner I think I will be placing an order Monday to compliment my new EP500,
