collapse expand iconDescription

From the respected pro audio brand Turbosound comes the iQ18B, an extraordinarily powerful 18" powered subwoofer built to deliver earth-shaking low end for live sound reinforcement. Equipped with a brute-force 3,000W Class-D amplifier, the Turbosound iQ18B adds thunderous impact to your PA, perfect for rocking crowds at festivals, concerts and other large events.

Punishing Lows Courtesy of a 3,000W Klark Teknik Amp

At the heart of the Turbosound iQ18B is a 3,000W Klark Teknik Class-D amplifier that pumps out high-current power with efficiency. Feel your basslines pound with authority and your kick drums crack with intensity. Even at extreme volumes, the amplifier stays clean and distortion-free. You get the headroom to push the sub to its limits without compromise.

High-Excursion 18" Driver Delivers Tight, Accurate Bass

The iQ18B is equipped with a heavy-duty 18" woofer sporting a large 4" voice coil and double-roll surround for extreme excursion capabilities. Experience incredibly deep, tight bass response down to 36Hz. The oversized driver produces fast-transient response and impressive sound pressure levels up to 133dB peak. Your low end comes across crystal clear, with none of the sluggishness that can plague other subs.

Onboard DSP for System Control and Protection

Turbosound includes their proprietary Klark Teknik DSP onboard the iQ18B for total system control. Get pristine EQ optimization and limiting that keeps the sub sounding tight and defined at extreme volumes. The DSP protects your components from damage. Network the sub via ULTRANET over CAT5 for easy digital audio distribution and remote control. Take your low-end presence to the next level with the Turbosound iQ18B 18" powered sub.

    I own 4 of these for over a year and they have been used in several events and in different live deployments. First as a FOH sub, it's fantastic. Cuts through the room/venue with ease and the processing options are great. The sub really comes to life in frequencies between 48-75 especially for a kick drum and bass guitar. The casters are of good quality and so far have lasted many shows and events both on smooth and rough gravel surfaces. As a drum wedge/sub it's also amazing and performs well beyond the drummers I've used it with. They are always happy to see it when placed on stage. My only gripe with this sub configuration is when transporting of the these subs, you are not able to stack anything on top of the sub as it would severely dent and damage the grill (yes even with good quality Turbosound transport covers) Ideally you would want a flat surface with a 1/4" board installed inside the transport covers grill location (such as the QSC KW181) so you could add items on top. Aside from that, you will not be disappointed with this purchase. A+ in my book.

    This subwoofer is the perfect compliment to my system! I run 2x IQ15's; and the sound is unbelievable! My only regret is that I didn't do this sooner.

    This sub out performs any of the competition it has a built in eq so you can set it for 20 to 50 hertz were the good deep bass is. I have had a ton of other brands. Jbl, Carvin, Yamaha but none even come close to this sub. Buy it you will love it !
