KSW-12 optimal settings and Home Theater questions from an HT-Newb

[-Justin-]

System:

Onkyo DD 5.1/DTS 595 (Reciever)

Sony DVP-S560D (DVD)

Klipsch SB-3 Bookshelf Spkrs (Fronts)

Klipsch SS-5 Surround Spkrs (Surrounds)

Klipsch SC-5 (Center)

Klipsch KSW-12 (Subwoofer)

Sony Wega 36XBR (TV)

Room size is fairly small (I'd say 15 feet wide, 25 feet long)

I'm not very audio-savvy and this is my first home theater, so bear with me. Put this setup together rather cheaply and seeking advice from your audiophiles out there. Have it set up right now with the fronts, surrounds, and center with standard speaker wire directly to the reciever, and the subwooder through the LFE inputs with MonsterCable. Sounds pretty good right now but I know its capable of more =).

What is the purpose of the "Phase" dipswitch, and what is its optimal setting?

What is the optimal crossover setting?

I've read that using the "Speaker level inputs" yields vastly superior sound compared to LFE input. Is this just plugging my speakers into the subwoofer directly, instead of jacking them into my reciever? And if this is true, is it really THAT much of a difference? (The Monster LFE Sub cable did cost me 50 bucks ater all =))

Any info/suggestions would be greatly appreciated.

Thanx in advance!

i am not veteran, just try my best to be helpful.

"phase" option make you can reduce the noise result from the overlap between main and sub. usually, it should be set in 0, if in your case 180 is better, you can change it. this option particular useful to that use satellite speakers.

the crossover setting is depends on your main and setting of receiver.if your main setting in receiver is large , remember set it 10Hz over your main. if your main can play 50Hz, your sub should set at least 60, that will make your system cover all band of sound.

you should set the small, that you should set it in line with your receiver's crossover, my denon is 80Hz, it means all sound under 80Hz will be send only to the sub other than the main. so you should set it around 80, and adjust it by your own ear.

the setting of sub is not a easy thing, you should make your ear make the final decision.
