(Open Box) Power for the sub, power for satellites and a thumping low end speaker. Smart design. Order today.

The 1,000-Watt INSPIRE iP12B powered subwoofer produces high levels of low-end punch with definition and clarity typical of larger systems. Equipped with a dedicated 600-Watt Class-D amplifier for the 12" long-excursion Low-Frequency (LF) driver and 2 x 200 Watt amps for your passive satellite speakers, the iP12B is ideally suited for small to medium-sized performance venues, houses of worship, boardroom presentations, nightclubs and much more. Lightweight (only 22.3 kg / 49.2 lbs) and easy to transport, the iP12B also features a 3-channel digital mixer with industry-leading KLARK TEKNIK Digital Sound Processing (DSP), Class-D amplifier and Spatial Sound technologies, plus convenient Bluetooth stereo audio streaming and iPhone/iPad remote control. This cool-running system delivers amazingly-deep, chest-pounding bass that will keep the party going all night long.

Tiny Subwoofer – Tremendous Sound
Designed for maximum portability and low-end support, the iP12B can be used as a standalone subwoofer with your powered full range speakers, or the backbone of a great-sounding speaker system. Setup is fast and easy; just connect your mic or mixer feed, your passive loudspeakers, and power. The iP12B instantly fills the room with the world-famous TURBOSOUND “sound” that has won the coveted Queen’s Award an unprecedented three times.

KLARK TEKNIK – Inspired Technology
KLARK TEKNIK is recognized worldwide as one of the most prestigious British audio companies, with a 40-year pedigree and even a TEC Lifetime Achievement Award to back it up. The Company has designed and manufactured products for world-class artists, and their legendary DN780 reverb processor is considered by leading audio engineers around the world as the industry standard. Check out their website to learn more about KLARK TEKNIK’s legendary heritage. TURBOSOUND is proud to incorporate custom-engineered KLARK TEKNIK Class-D amplifier and DSP technologies into their products.

DSP – the Secret to Superb Sound
From the instant your signal enters the iP12B, the built-in DSP takes over ensuring the highest possible signal integrity. Much more than just selective EQ enhancement, the 24-bit processor analyses the incoming signal and intelligently applies specific filters to actually improve the sound quality. It’s like having an audio engineer monitoring the input and output signals, dialing in the perfect EQ and constantly making subtle adjustments to the crossover, compressor/limiter, three discrete amplifier channels and more, all of which adds up to significantly better sound.

Custom-Engineered Drivers
Our speakers are designed specifically for each application – it’s what sets us apart from the competition. When you buy a TURBOSOUND speaker system, you can rest assured that the speakers inside have been engineered to perform flawlessly in conjunction with every other element for truly professional results.

Built-in Digital Mixer – Comprehensive Remote Control
The iP12B features a fully addressable onboard digital mixer with two combo jack/XLR connectors that accept balanced and unbalanced connections for dynamic mics and line-level instruments. The simple and intuitive user interface consists of a single rotary push-encoder with Process, Setup, Exit and Enter function buttons. A beautifully-backlit LCD display controls DSP functions including mixer parameters, 3 band EQ and presets. All settings can be controlled locally, or via free downloadable iPhone/iPad apps – and locked down to prevent unauthorised access.

You get total control of the iP12B directly from your iPhone or iPad. This amazing feature lets you adjust all settings from either the listening area or the stage, for the perfect sound every time. The dedicated apps are available free of charge at, or from the Apple App Store.

Bluetooth Ready
The days of tape decks, CD and even mp3 players are long gone. Now your music lives on your smartphone or computer tablet, so you can stop searching for those outdated cables and fancy adapters. An industry first, the iP12B puts all your music at your fingertips via stereo Bluetooth. Now with a simple wave of your hand, you can stream music from any Bluetooth-equipped iOS device, such as your iPad, iPod touch, iPhone or even your laptop computer.

Stunning Performance – Superb Value
The INSPIRE iP12B powered subwoofer stands head and shoulders above the rest of the pack and delivers exceptional performance, even when pushed to the limit. Ultra-lightweight and powerful with a custom-designed 12" long-excursion LF driver, an integrated mixer, stereo Bluetooth streaming, iPhone/iPad remote control, 1,000 Watts of KLARK TEKNIK’s Class-D output power and Digital Sound Processing, the iP12B is ideal for both portable and installed applications.

Well built compact subwoofer!

Comments about Turbosound iNSPIRE iP12B 12" Powered Subwoofer:

The Turbosound IP12B is a great option when you need a compact set up and prefer the true full range sound you cannot get without a dedicated subwoofer. The price point cannot be touched, and this sub performs well above that. The fact that it has a built in amplifier for satellite speakers takes it over the top! The Bluetooth input works perfectly and the Turbosound iOS control app is amazing. Overall, the sub packs a very clean punch and can go lower than you might think.

Comments about Turbosound iNSPIRE iP12B 12" Powered Subwoofer:

I use it both when setting up a small PA for music playback, and for a small acoustic rock band, to provide some additional thump for our drummer's kick drum (who plays surprisingly quiet for a drummer). I also have used it to spread the bass guitar's lower frequencies around. Sounds very good. Most of the settings are pretty easy to understand. The GREAT thing about this unit and that makes it so unusual is that it has two additional built-in amps for running PASSIVE top FOH speakers. You can send your pre-amp level signal to it from the board, it does its thing splitting the highs and lows based on the crossover frequency you choose, and then the standard Speakon outs on the sub's rear panel can power your passive PA speakers sending the highpass signal to them powered by two 200W amps. Great design, simple setup. Tiny package.
The only trouble I've had is pairing it to my iphone for music playback. I haven't figured out the magic sequence of events yet, but if you download the TurboSound App for your iPhone (which controls the parameters of the subwoofer), you then have to make a second BT connection to it for playback from the same phone. It's been hit/miss getting that to happen.
It's easier to just route the phone for music playback into the PA via a cable. Then there's only one pairing to manage, which is easy using the TurboSound App.


works for me !
