If you want the amazing flexibility and precise sound of a Turbosound Flashline stage monitor that you can integrate with the amp system you already have, then you're looking at the right tool for the job. This TFM152M includes Turbosound's amazing coaxial speaker system, which focuses highs and lows so that they come from the same point, dramatically improving sound consistency across the stage while decreasing the size of the cabinet. And with two power-handling modes, this TFM152M is ready to integrate easily into your monitoring system.

Pro-quality coaxial speakers deliver consistent sound

Unlike typical monitor wedges, which use either a single driver or a traditional low- and high-frequency driver layout, the TFM152M includes a custom Turbosound coaxial driver. This speaker includes a 15" main driver with a carbon fiber cone and neodymium magnet, at the center of which is a 1.4" titanium dome compression driver. Sweetwater sound-reinforcement techs and performers love this kind of speaker, since all the audio comes from a single point. This ensures that you'll hear the same thing, no matter where you are onstage.

  • Coaxial speakers deliver centralized sound for consistent monitoring
  • 15" neodymium-coil driver with carbon fiber cone delivers powerful lows
  • Titanium-dome 1.4" compression driver reproduces smooth highs

Two power modes provide maximum setup flexibility

Every live sound monitoring system is a little bit different, and to ensure total setup flexibility, Turbosound outfitted their TFM152M with a 2-mode input. A simple switch lets you select from Passive mode and Bi-Amp mode. Passive mode is a more traditional full-range setup, which runs the entire input through the TFM152M's internal crossover for automatic frequency distribution. Alternatively, you can set the TFM152M to Bi-Amp mode, which divides the speakON input into two channels, allowing you to send separate feeds to the high- and low-frequency drivers, controlling the balance from your mixer instead.

  • 2 power-handling modes offer extreme monitoring setup flexibility
  • Passive mode runs full-range audio through the onboard crossover
  • Bi-Amp mode accepts separate high- and low-frequency signals

Turbosound TFM152M Passive Stage Monitor Features:

  • Touring-ready 2-way/2-mode passive stage wedge
  • Dual modes include Passive (full range) and Bi-Amp (split LF/HP)
  • 350W RMS/1400W peak (8 ohms) power handling in Passive mode
  • 310W RMS/1240W peak (8 ohms) power handling LF driver in Bi-Amp mode
  • 40W RMS/400W peak (8 ohms) power handling HF driver in Bi-Amp mode
  • Coaxial 15" LF/1.4" HF drivers provide centralized sound for consistent projection
  • Low-profile design looks good and provides 60-degree/40-degree dispersion
  • Fiberglass-reinforced 5/8" plywood provides added protection and stability
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
