It takes just a fraction of a second to appreciate the clarity of Alto Professional’s premier Black 18S Subwoofer.

Designed in the USA, the 18S Sub features an 18” ultra-high excursion cone transducer and 4" voice coil with 2400 wattsof drool-inducing, Class D   power. And with the free Line Drive app, you can wirelessly adjust them with your iPad or iPhone to level-match, EQ, time-align, and more. Weighing in at 105 lbs, these babies are NOT for the faint of heart. But that's ok,  neither are you ...or your music.

With the Alto Black 18S Subwoofer you'll hear bass instruments are full open. Percussion is punchy and authentic. Guitars and keybaords come alive and are rich and energetic. Even today’s complex, multi-layer music is reproduced with grace & nuance at any volume from cocktail hours to the full-throttle marquee act.

2400 Watts of Crazy Power
Designed from a clean sheet of paper to exacting standards with purpose-matched components, Black loudspeakers provide jaw-dropping sound without even breaking a sweat. Each loudspeaker is optimized with a 90° x 60° coverage field, an extensively tested high-frequency waveguide, a DSP-controlled custom crossover, and active thermal protection. When you need that extra oomph, Black delivers.

Fine Tuned Power
The Black 18 Sub features a powerful 18” low-frequency, long-excursion driver and 2400 watts of peak Class D power. Designed and tuned in the USA with carefully selected, complementary components, the Black 18 Sub comes stereo XLR outputs, and stereo inputs, with a Mic/Line input on the left channel, XLR on the right channel.

Mobile Control
Even if you can’t reach the speakers, you can still adjust them on-the-fly with your iPad or iPhone. The entire Black series comes equipped with wireless technology so you can tweak parameters remotely via the free Live Drive app. Level-match, adjust EQ, time-align and more—from anywhere in the room. It’s streamlined, sound-shaping control at your fingertips, so you can easily adapt the speakers to new venues or performances away from the mix position.

Able to adapt to any situation, each Black loudspeaker features a built-in mixer with a variety of inputs and outputs. The cabinets are scratch-resistant, fronted with a powder-coated grille, and ready for anything from high-end club installations and gigging bands to corporate AV and mobile DJs—even their rubber feet are reinforced with steel. Hang them via the integrated M10 rigging points. Use them as floor wedge monitors. Or simply mount them via the built-in pole sockets. Use the free Live Drive app to obtain even greater capability when its showtime and the pressure is on.

Comments about Alto Black 18S (2400 Watt, 18" Active Subwoofer With Wireless Connectivity):

Earlier this year 2014.... I decided to buy a new powered subwoofer. The common notion was I wouldn't be "HEARD" If I did not go with the norm (kw181 elx118,prx618,etc) I asked Mike G. to hear the alto because It was similarly priced and seemed like a nice design. He went back and forth with the Alto BLACK sub vs the other subs and I was blown away. Obviously every sub will sound different with gain structures and input gains dependent on brand and manufacturer but for some reason there was a low 29-40 hz(my guess) bass coming out the alto sub that was missing from the other subs. We played a few songs with some serious low end and I said (whoa ) is that coming from that ALTO BLACK.... he said YES..... After That I was SOLD..... After that initial Purchase I ended up getting 3 more units and now have 4 units total. These subs have an unbelievable sound and outperform MOST subs in the price range. Mike Let me sit in that room for an hour and a half and play with that sub. Im sure he missed out on some sales but thats the best customer service you can possibly give. Im sure he was happy after I decided to purchase the subs. Im a very very very happy customer.
