Comments about American Audio PXW18P 18" Powered Subwoofer:

We bought this subwoofer as an upgrade to our backline. Normally Pro-Audio backline support is provided by the venue and/or promoter; but from time to time we are booked and part of the deal is BYOSS (bring your own sound system). So we needed a quality sub - something that could fill a room of 100 to 800 - and this sub does just that!

We were hitting the road for a 3 day - 3 concert weekend and needed this sub on the trailer before we left. It arrived (ABF Freight) exactly 15 mins before we pulled out with the trailer. So we took it off the freight truck and tossed it in our trailer - box, packaging, everything. We arrived at the first venue several hours later, unpacked it from the box, carried it inside (on a flat-bed tow dollie) and put it on stage. No time to read a manual... we looked at the back panel - it made sense - so we connected to the primary backline - into the snake - and once everything else was setup we turned on all the power and BOOM! that thing roars! Normally we spend 10 mins (depending on the room) trying to dial in the kick-drum... but with this sub, we had it Eq'd and leveled in about 2 mins. It more than filled the room (500 seat) and we barely pushed the volume (about 40% output). Although 2 subs provide a balanced 'look' on stage, you do not need 2 subs with this thing. One sub is more than enough for indoor rooms under 850 occupancy.

One thing - has nothing to do with the sub; but if you buy one, you'll need to know this. If you buy the 3-5 day shipping... it's more like 7 day shipping. Due to it's weight (180 lbs) they use a freight company, not UPS or FedEx. So that causes delays in movement. Luckily, I called the freight company and they worked with our schedule to make sure it arrive just in time. That said, it's a great sub and if we need another... we'll get one of these.

Comments about American Audio PXW18P 18" Powered Subwoofer:

Have owned one for 18 months. We work atleast 3 dates per week, in and out of churches and auditoriums.. Having 5 string bass, heavy kick drum, and a super-low bass singer in a southern gospel quartet, I never thought i'd be happy with this sub.. but, with the 45 day return policy, I thought I would give it a try before spending alot more on Mackie. This sub is exellent. It provides warm, punchy bottom end in auditoriums filled with 1,000+ with only one cabinet.. Week after week, load in..load out, its built like a tank, and has never given one minutes trouble. Great sub, at any price..

Crazy Bass for such low price

By El Quinto Efecto

from Fabens, TX

Comments about American Audio PXW18P 18" Powered Subwoofer:

I bought a pair of these for our band and these look pretty big and compact. Believe me I'm big, and I couldnt take it out of the box by myself, 170 something pounds of pure power, I still think it's heavier. The sound quality is off the hook, really deep bass and there is no way these babies can get warm, not even a bit, after a couple of hours playing with them full blast. Used them for the first time at a party outside and we covered the entire block with bass. Im surprised with these subs. Don't be fooled by the price they are awesome!
