How to Add a Subwoofer to Your Setup (LFE, Crossovers, Bass Management, Oh My!) 

Three subwoofer setups: 1. Three-way (the most common) means the output is fed into a crossover and split. Most subwoofers have a crossover built in with an ability to adjust the crossover frequency. 2. LFE (Low Frequency Effects) a dedicated channel specifically for theatre release and needs a dedicated output. Most often the LFE can't contain information above 125 Hz. 3. Bass management system is a blend between LFE and three-way setups. You still need a dedicated output.

@tallguyfilms can u show how u hooked your yamaha sub i have the same one

Couple ??? What should the sub crossover be set to for 5.1? I want to livestream motorsports races through OBS. What do I do about the lfe channel? Do I just leave it blank or should I use a plugin like Waves DTS Neural™ Surround UpMix. I'll be bringing the mics, pa, cams in through Focusrite Scarlet

Thank you so much. It was so useful.

liked very much

For music, do I want the sub to be at the same level as both nearfield monitors combined, or match levels to one nearfield?

For the 3-way system, does adding the extra 10dBs to the sub (12:04s) affect the signal level going into the stereo monitors?

Krk 12 inch sub and 8 inch studio monitors. What crossover should the know on the sub be?

Maybe this is a silly question, but if I output a LFE signal from the Scarlett 18i20 to my KRK sub with a single jack, I'll have two inputs to choose from on the sub, L and R. Where do I insert the jack? Does it matter? Thanks

I have a Scarlett 18!20 and Jbl lsr6312sp for a 5.1 setup do I go into the input of sub im getting sound from other 5 monitors just not the sub.

Why do you need the subwoofer to be 10DB louder for film content?
