No, low level outputs are simply not amplified to listening levels; they are full range in frequency. The "low" does not refer to the freqency range of the outputs in any way. Svoboda already stated that he does not have a sub woofer output; this IS a low level output that is filtered to only send low frequency output to an external amp. I think you are confusing the term low level with low frequency.
Yes, Svoboda should worry about filtering high frequencies from the subs. No, he does not necessarily need to do so if he 1) Does not care about the added distortion and 2) The subs are not run near their rated power limit. Sub woofers have very large coils. Because of this is takes a combination of high power to damage them. Tweeters on the otherhand are very susceptible by damage from distortion due to their very small voice coils.

If the low level outs are not sub outs and are not lower than the other output lines then they are not true low level outputs. That was thee whole reason for low level out in the first place.

Another thing, subs can be damaged by frequencies that are too high or too low, even if there isn't high power present. You make it sound like it isn't possible to damage them otherwise.

The main point I was trying to make was that you need to make sure that the signal that ends up at the speaker(s) needs to be within the tolerence of the speaker(s). Passing higher or lower frequencies will eventually damage the speaker.

Storm, his reciever shows it has two pairs of preamp outs. Thes ARE low level outputs meant to go to a power amp. They are full range. A sub output, which he does not have, would also be a low level output, but, would be a low pass signal at maybe 120HZ or adjustalble.

Also, I don't think the high freqencies going to the sub would damage it, but like Elcarion says might cause distortion. I would certainly use a filter of some kind. If you send bass signals to the tweeter, it will burn up in a heartbeat.
