A Mighty Sub That's Mighty Portable!

If you're looking for an easy way to add thumpin' bass to your portable PA rig, then Turbosound's iQ18B powered subwoofer is right up your alley. This 3,000-watt, 18" subwoofer is a lot more then a bass-blasting machine. Loaded with cool features such as Klark Teknik digital signal processing and Ultranet digital audio connectivity, the iQ18B is high tech, but only in ways that actually make your job easier. What's more, lightweight Class D amplifier technology combined with conveniently back-mounted castors also serve to make the iQ18B one of the most portable subwoofers in its class.

Turbosound iQ18B Powered Subwoofer at a Glance:

  • Ultranet technology makes advanced integration with the rest of your gear easy
  • Flexible enough for live sound professionals, Durable enough for life on the road
Class D Klark Teknik power amplifier provides high output and low weight

A decade ago, if you've have told anyone here at Sweetwater that we'd someday carry a 3,000-watt, 18" powered subwoofer weighing only about 100 lbs., we probably would have laughed out loud. But here it is, the Turbosound iQ18B, and it's an amazing way to beef up your live sound rig. Add to that the fact that the iQ18B is about 2' in any dimension and that it's got integrated castors on back (so it still sits flat) and you've got yourself one truly portable workhorse sub.

Ultranet technology makes advanced integration with the rest of your gear easy

Now let's focus on the technological side of the Turbosound iQ18B. The iQ18B 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 iQ18B includes Klark Teknik digital signal processing, which provides total control over your sound, including extremely cool speaker emulation.

Flexible enough for live sound professionals, Durable enough for life on the road

Urtranet connectivity isn't the only thing that makes the Turbosound iQ18B an extremely flexible live sound tool. A full-featured LCD interface and USB connectivity for software-based configuration make that aspect of the iQ18B totally easy to use. On an even more practical side, you get things like an integrated 36mm (1.417") pole mount and Neutrik powerCON connectors to make configuring your iQ18B powered subwoofer with other gear a breeze. Top it off with a rugged powder coated grille and sealed birch plywood enclosure, and you can take your iQ18B on the road, worry free.

Turbosound iQ18B Powered Subwoofer Features:
  • A front-loaded powered subwoofer that's perfect for portable PA and installation applications
  • 3,000 watts (peak) of power features Klark Teknik Class D technology for maximum output with minimum weight
  • 18" low-frequency driver with 4" voice coil and double suspension delivers a ton of output
  • Birch plywood enclosure provides incredibly punchy and focused bass
  • Klark Teknik digital signal processing provides total system control
  • Speaker modeling includes accurate models of industry standard speakers
  • Ultranet digital audio networking connects to mixers and other sources
  • Program settings via USB or with the onboard LCD
  • Semi-matt black paint finish and rugged powder-coated steel grille easily withstand life on the road
  • 1.417" (36mm) pole mount supports satellite speakers and top boxes
  • Back-mounted castors make transportation easy but still provide you with a stable base
  • Two channel XLR combo inputs with XLR link outputs make audio connections easy
  • Chainable Neutrik powerCON connectors add security to your power
Get the thumpin' bass where you need it with the Turbosound iQ18B powered subwoofer!

For your info iQ18B
Don't let the 4 stars I posted fool you. These pound! I'm running them under a set of JBL SRX835P and they are pretty impressive. The on board DSP is a benefit to the overall performance. Bought them used but brand new condition. Would love to have another set. Originally wanted to purchase the matching SRX subs.
Sub woofer
Great kick to a sub power punch light weight i recimend 100%
Great subs!
I have a pair of Turbosound IQ12 tops, and these pair with them nicely. A great upgrade from my previous subs.
Awesome subs
I purchased a pair of these and was blown away by them! really good subwoofers for its price , one tip I would give is to change the eq settings. I changed mine to user eq and set the low shelf in the 60-70 range, and heard and felt a way bigger difference, really good subs.
Very happy with my purchase
The purchase of the turbosound IQ18B was a great buy. I'm very pleased that I purchased this item from sweetwater. The service was excellent and so was the communication. Zac was very Knowledgeable and easy to talk to. I'm pleased with the product I purchased as well.
