Curious on peoples opinions on the above. I heard two of these subs at my work place playing some recorded music and they absolutely blast bass, more than what my SVS PB-13 ultra is capable of. How would they sound in a home audio set up? I understand the lowest note they play is about 35 Hz or so but that's fine for most music? How would one of the proper PA subs sound in conjunction with my SVS taking over the lower bass?

With two 18" PA subs I'd be afraid I would damage my house. I used to have a 15" bass-guitar amplifier, and when I cranked it up the whole house buzzed. Not just a rattle here and there, but every surface was making noise. I could hear the air ducts buzzing.

First of all, please note the "Sticky" at the top of the page requesting that subwoofer qustions be asked in the "Subwoofer Forum".



To answer your question, most PA subs are optimized for high SPL from ~35 Hz and up. This is fine for most music, but for HT applications, they leave a lot on the table. For example, here is a JBL 18" PA sub:
http://www.sweetwater.com/store/detail/PRX518S/

The spec's say:

# Frequency Range: 37 Hz - 140 Hz

# Frequency Response: 52 Hz - 110 Hz

(The difference between "Range" and Response" is that the speaker will have some output to the quoted "range", but it's *usable* output will be limited to the "response".)

Within the Frequency Response of 52 -110 Hz, these "subwoofers" will output 129 dB.
However, for HT applications, you want usable extension down to 20 Hz or below, and most people don't need 129 dB of output.

dont be affraid to use them they should rock just watch playing a movie to loud unless you have a high pass filter on them you will blow them apart . if you put a 25 30 HZ high pass they will be fine but you will be loosing some out put down low . thats what seperates a good home theater sub from a pro audio sub . if you are powering them with a pro amp it should have a seletable high pass filter on it you could use that to protect them from some of the 5 HZ movies out there . dont ask me how i know about blowing subwoofers to kingdome come
