Do I need a sub?

We've beaten this subject to death.  Short answer: You can have one, but you don't absolutely have to have one. Take a look at this thread:

If you feel you are missing slam, maybe look into improving the speaker placement or adding room acoustics. They may give you more for your dollar without adding a new speaker which may be hard to fit acoustically.

Large room, 16-17” vaulted ceilings.

 Left speaker (from couch) faves open hallway, staircase 
right speaker in corner,

does it matter where a small small sub goes?

I have Lansche 4.1 with two 10 inch active woofers which is supposed to go to 20hz.

But after augmenting it with two Scaena 18 inch subwoofers, it go more dynamic with stable bass foundation, wider and deeper soundstage.

The answer to “Do I need a sub?” is always yes. Even if you already have one, or two, or three, or more 😀 Multiple subwoofers is the path to high end bass and high end audio in general. Yes, if you high pass your mains they will play louder and clearer because it limits cone excursion on the lowest notes and hands that duty to the subwoofer which is designed specifically for that task. That’s what I do in my system and it sounds great. I’ve got two subs and my end goal is at least four. Not for loudness (although that’s fun sometimes) but for bass even-ness, extension and clarity. When you get a sub, invest in a MiniDSP module or something with DSP capabilities. It lets you precisely control the crossover and crossover slope, apply notch filters to help minimize room resonances, and do other things like apply Linkwitz transforms which can extend the bass lower as long as you have the amplifier watts and available cone excursion (for sealed subwoofers anyway, not sure if that works with ported). DSP and subwoofers should be married to each other in high end audio. Best of luck to you.

In my listening time (30+ years), I've always used a single sub. The important thing is finding where in your room it sounds best. In my current home, I tried moving the sub two feet and it sounded horrible! Moved back to original location and it purred like a kitten! Just got to find the right place.
