"Is this subwoofer enough to...?"
Yes.
"Will my neighbors?..."
Yes.

Let me sum up everything:
"Can I accidentally displace my house from its current foundation with this piece of audio equipment?"
....probably, yes.

A good friend has one. I desperately wanted one. I ended up getting an M-15 V2 (which I still absolutely love). This thing is a ****ing monster. There are very few subwoofers that can move the kind of air that this can, and all the rest of them are going to be a lot more expensive than this is.

This does not go on sale for a price like this very often.

Oh... and make sure that you have help to move it and unbox it. This sub is 171.6 lbs. I bet it's over 200 lbs boxed.
It will also come shipped to you FREIGHT, strapped to a wooden pallet.

I just point that out because a lot of people don't realize just how monstrous these things are. Be prepared.

Get some furniture dollys and a moving blanket or two so that you can (carefully) tip it onto its side on a dolly and move it around on wheels (after getting it unboxed). If you have to get it up/down stairs... I recommend furniture moving straps and a strong friend or two. Bribe them with pizza/steak and beer if you must.
One day I'm going to get one of these. Today is not that day, but one day.
It's perfectly fine, I have them on 20 amp circuits. They draw peak power for a fraction of a second, not like a space heater pulling constant current.

Code possibly a glitch as it doesn't work on other Monolith products, so don't wait.

This thing is a monster both in performance and size/weight. I'd be temped if it weren't for those factors.

I have two 15s and a 16. The 16 is significantly heavier, around 175 pounds.

This can be ~32-35 amps peak according to the specs... How does one run this in a normal house?

How does the 15s sound compared to the 16?

I bought this when it first came out and it's awesome. I paid 1750 and was happy with that deal. This one is great.
It does weigh a ton and you aren't moving it safely on your own.

Because those are peak burst numbers and unless you want to fry the voice coil you don't run square waves for fun at maxed gain.

16 has more output, really not a huge difference.

Thanks for the reply, I assume this also means that the peaks over ~20 amps are short enough to not trip a breaker under normal operation? That's the real question, can I run it on a normal house circuit?

Great points, also make sure you are okay having a huge black box out in the open, it can be an eyesore. Mine are all hidden behind fabric walls.
