LFE vs. Y input??

I'm just curious as to whether there is a difference between hooking up your sub via the LFE input or using a Y adapter and hooking up to the "normal" input.

I'm using a Klipsch KSW-15. It does seem to sound deeper when I go into the "regular" input than the LFE. When I get the Avia test disc in, I'll test further.

Thanks.

I dont think there is a difference. Klipsch said there is, but I dont think I agree. I own a KSW12 and got this advice on this forum.

1. Set all your speakers to small

2. Go into the LFE input only

3. Get a calibration disk

4. Calibrate all speakers to reference level

5. Set the sub +/-4dB higher

The LFE input most likely bypasses the subwoofers internal lowpass filter. Connect to this input, play a subwoofer test tone and move the lowpass control knob/switch. If the tone is not affected the input has bypassed the filter.

According to the owner's manual of the KSW-15, the LFE input bypasses the sub's internal crossover. This is exactly what you want to do in a 5.1 system using the receiver's digital crossover.

Connect the KSW-15 to the LFE input ONLY. No Y-cord.
