Alto Professional's Black Series is a full line of elite speaker systems, each designed to exacting standards with premium, purpose-matched components and immense built-in power. Black Series speakers have been designed with one goal in mind: satisfying the ears of your audience with the most gratifying and immersive sound experience they've ever had. Both Black Series subwoofers-the Black18S and Black15S-has been crafted to thunder with finely tuned sound in a virtually limitless variety of applications: from touring rigs to permanent installations and everything in between. And with 2400 watts of peak power each one comes equipped to thrill.

Beyond their differences in transducer size, each Black Series sub contains the same 2400 watts of earth-shaking, low-end power and specifically crafted, purpose-matched components for maximum efficiency. Designed and tuned in the USA, the Black18S and Black15S both come with stereo inputs and outputs, adjustable level and polarity controls and precision-engineered cabinets, which have been designed to deliver maximum sonic impact.

Black Series subwoofers are precise and fine-tuned. And they're not fragile. Each one comes ready for pretty much anything you can throw at it-even their rubber feet are reinforced with steel. Perfect for touring rigs, mobile DJs and other on-the-road applications, each Black Series sub has a heavy-duty 18 mm hardwood plywood cabinet, which is covered in a rugged, extremely durable scratch-resistant finish. They're also surprisingly easy to carry with comfortable, custom-molded handles.

Your audience is waiting to be amazed, and that's what Black Series subwoofers offer. They're ideal for installation in amphitheaters, clubs and more. With a Black Series sub, your audience will hear-and feel-high-powered, thunderous bass that delivers a breathtaking sonic experience.

Great Sub

By Kerry West

from FLowery Branch Ga

Comments about Alto Black 18" Active Subwoofer 2400W:

Started out getting the ev sub for the price. Learned fast it was very weak. Choose to bite the bullet and step up to the QSC KW118 and although it is a very good sub and was very punchy it just didnt have the BOOM for hip hop and dubstep. Thought I would try this sub after hearing it in the store and boy glad I did. After playing one song through it when I got it home I knew the sound was there I was looking for. The ev I would limit even trying to make it hit, the qsc I couldnt get to limit no matter what I tried but just not the right kind of bass. The alto black I can not get to limit either but the bass is there....New sub that just came out so time will tell but the sound is better than all the subs I tried.

Amazing Powered Subwoofer

By Dj

from Ft. Lauderdale & Miami Fl

Comments about Alto Black 18" Active Subwoofer 2400W:

The Alto Black Series 18" subwoofer is the Best powered sub that I've heard in a long time. After hearing it in Guitar Center, I finally took one home to try it out. At first, I was disappointed but I shortly discovered that "YOU MUST DOWNLOAD THE APP ON YOUR IPHONE OR APPLE DEVICE BEFORE YOU START PLAYING". This will allow you to maximize the true potential of the subwoofer. I've used the Mackie SRM 18, JBL 18, EV 18 & QSC KW18 and so for the ATLO BLACK 18 is the FREAKING BEST BY FAR. I've used the Alto Black 18 Sub for the first time last Saturday in a clubhouse at a B-day party and TRUST ME the recessed lights literally came out of the ceiling after playing. This was some of the deepest bass that if heard in a powered subwoofer for a long time and if I may, the best sound ever. I'm very happy with the Alto Black Series 18" Subwoofer so far and for that I've rate it a 5 STAR because of the price, sound quality, Best powered low end sub and quality engineering. Only thing I wish, it would be nice if it has wheels for easy moving.
