Big Power and Built-in DSP for Incredible Sound

You get plenty of power plus easy portability with the Turbosound iQ15 powered loudspeaker. It's easy to move largely due to the efficient Klark Teknik Class D power amp, which puts out up to 2,500 watts of power while keeping the weight down. You can shape the sound with onboard DSP that gives you the best of both worlds, providing a full-range response at low volumes while giving you transparent limiting at high volumes. The result is great sound no matter what situation you find yourself in.

Turbosound iQ15 Powered Speaker at a Glance:
  • Plenty of power for any gig
  • Complete system control through DSP technology
  • Lightweight for easy transportation
Plenty of power for any gig

The Turbosound iQ15 powered speaker is a solid solution for any number of situations. It sounds great at low volumes, but with 2,500 watts of power tucked away inside, you can fill large rooms with sound. This sound is pumped through a 15" speaker with a low mass voice coil for excellent transient response and a titanium dome 1" high frequency compression driver that provides extended high-frequency reproduction.

Complete system control through DSP technology

Now let's focus on the technological side of the Turbosound iQ15. The iQ15 features Ultranet communications connectivity via standard Cat 5 ethernet cable, which allows you to send digital signal to and from your Ultranet equipped mixer for maximum sound quality. If you're already familiar with Ultranet, then you already know how powerful and easy to use it is. If not, call your Sweetwater Sales Engineer for a full explanation. On top of that, the iQ15 includes Klark Teknik digital signal processing, which provides total control over your sound, including extremely cool speaker emulation.

Lightweight for easy transportation

It would stand to reason that big power would come with serious weight. But Turbosound doesn't subscribe to that theory, and thus loaded the iQ15 with a Class D power amp. Class D means you get the power you need but you won't break your back.

Turbosound iQ15 Powered Speaker Features:
  • Lightweight and easy to move
  • Onboard DSP to shape the sound
  • Speaker emulations built in
  • Tons of power from Class D power amp
  • Multiple internal rigging points for installation applications
Engineered to sound great - Turbosound iQ15!

These are just simply WOW!!!!

Having been in the production business in varying capacities over the years, these speakers are the best I have purchased for my audio applications. I had never heard of this brand before, using all the other well-known brands out there. It came highly recommended by other sound techs, so I took a risk and bought them. So glad I did, well worth the risk, and the compliments just keep coming in on my mix and sound! Thanks Sweetwater for helping to make this purchase possible! Great customer service, and when I did call to ask an overall out of the box question day of show, I received an excellent experience from your front line techs!! THANK YOU to the guy who gave me re-assurance, that nights gig went so well with these new additions to my P.A. I also highly recommend the pull over covers. They are padded well, and protect the investment.

Wonderful sound, portability, DSP and Ultranet

Purchased a pair of these speakers along with a Turbosound iQ18B sub-woofer...all per the recommendation of Nathan at Sweetwater. This is part of a new, portabale sound system our church purchased recently via Sweetwater. We were looking for a system that had high quality sound and as simple a connectivity and setup effort as possible. The Turbosound speakers work terrific with the Behringer XR18 we also purchased and since they have power amps built in and connectivity via Ultranet...we couldn't ask for an easier setup! These Turbosound speakers also have DSP settings for each other...ie, they have matched crossover frequencies. Highly recommended !!

I was hesitant to buy from Turbosound as I had only heard of them in passing. Let me say I am not disappointed. I have owned JBL Eon speakers, as well as Mackie. IMHO, these are BETTER. When I say better, I mean the are "in your face" with the sound. Some live sound cabinets have that hollow mids thing that sound good only when pushed. These sound good any way you play them. Make sure that you are giving them adequate input. If you do, they will knock your socks off. I have 2 IQ 15 and 2 IQ 15B subs. Set them up the right way(which is very easy with the LCD display on the back) and they perform flawless. These are for live performance. If you are worried about scratches, then buy covers for them. They are made like tanks..super heavy construction. The IQ15B is also very easy to move with the casters installed. I have owned these for a couple of months and gigged with them weekly with no problems. My setup covers large rooms easily and smaller outdoor venues are no problem. Set them up right, and you will like them.

From 1000w of funk to 2500w of Krunk

I was reluctant to buy a line of powered speaker I was unfamiliar with, but a friend whom I trust recommended the Turbo Sound iQ Series for me to try. So I did. After using first, two QSC12, 1000w as mains, I was not totally happy so I switched to EV12, 1000w and still was not satisfied with what I was hearing. The very first time I setup with two iQ15, 2500w I was floored. Even at low levels during my jazz & standard set the clarity was amazing. But the real test came when got the opportunity to crank them at an outdoor High Energy Dance set in Centennial Park, in Atlanta. The sound was clean, full and more than loud enough for the crowd. So far I've been excited everytime I've used them. Keeping my fingers crossed and the volume @ 10.

Turbosound iQ15s POUND

Fantastic. Unreal. Crystal Clear. Lots of low end. Will blow the doors off any other powered speaker in its class. Do not hesitate to buy these!! One caveat, they are a little heavy. But they are built to last. I've had EV, Behringer, QSC, and JBL. NOTHING touches these bad boys. Wow. Just wow.
