Finally, a soundbar designed for the classroom... not the living room.
Audio is 40% of the learning experience.
The speaker selection is the heart of any sound system design, be it a concert hall, a church, or a classroom. Soundbars can be a wonderful solution to installation and space issues, but that typical soundbar from your local audio or discount store was designed for a living room or residential entertainment system. With maybe 6 kids on a busy Saturday, you’re probably OK with that in your 200 sq. ft. home TV room, but a US classroom is typically 5 times larger than the average residential living room.
"GOOD ENOUGH" IS NOT PART OF OUR MANTRA
Leading Edge is the first company to address this problem, and our soundbar eliminates the need for complicated and costly installation. Simple one-cable connection.
If you are dedicated to a student's successful education, just "good enough" is NOT good enough. Our signature sound is simply amazing. It carries through every one of our products. Vocals are stunningly crisp with just the right amount of bass that makes voices sound comfortable all day and doesn’t require a subwoofer that would rattle the classroom next door. We don’t build our speaker systems to favor car chases or booms and bangs. And this is the first soundbar to be specially designed for maximum loudness before feedback with wireless teacher-worn microphones.
KARTBar™
Mobile sound should be noble sound
Your beautiful new interactive display panel possibly has little 1” x 2” speakers ( usually at the bottom of the board) which are just not going to project into a 1000 sq ft. classroom. Even 40 watts into tiny speakers don’t make them produce room-filling audio. It's not just a question of loudness, but clarity with minimal distortion.
The sound source, in this case the soundbar, needs to be above the video display but angled down to the students throughout the classroom. The KARTBar is perfect for mobile carts, which all need quality sound. Just add a compact power amp and you have an extraordinary sound that goes anywhere.
High Definition Audio is on a roll
Interactive display panels have revolutionized the classroom, but they often have not kept pace with the audio potential. Mobile carts present a whole new challenge to audio, but the KARTBar was designed especially for this task with tilted mounting bars and a lightweight package that will interface so easily with virtually every display panel's back panel VESA mounts.
Real birch ply cabinetry results in a lightweight, 11 lb enclosed complex speaker system
The angled front panel spreads the sound 120 degrees horizontally
Our MB-37 mounting bracket utilizes standard VESA mount points, is extremely rigid, easy to install and offers a 10 degree downward tilt for the soundbar to reach the proper listening area of the classroom.
Our exclusive angled edge steel mounting bars have tremendous vertical rigidity and easily attach to the VESA mounting holes on the rear of the TV/interactive display panel to give the soundbar 10 degrees of downward tilt.

Stereo WUNDERBar™
We’ve looked at this from all angles
Our Stereo WUNDERBar has an angled front panel that spreads the sound across the entire width of a classroom. The Stereo WUNDERBar is the perfect answer for an easy to mount, amazing-sounding true stereo speaker system.
Its trim 5” height fits nicely above interactive Display Panels or video projector installations.
The Stereo WUNDERBar offers the ultimate in full range voice performance, yet remains excellent for reproducing musical content. Subwoofers should not be a requirement for great soundbars.
No molded thin wall plastic boxes here. Real high-performance transducers and precise, complex crossover networks are combined with meticulous hand-built cabinetry. We utilize professional-level components that offer the best performance for a classroom environment.
At only 19 lbs, the Stereo WUNDERBar installation is safe and easy with any dual channel power amplifier system.
Wall Mount Accessory
The Wunderbar's 6 3/4" depth and downward tilt bracket is ideal for mounting above wall mounted Interactive display panels. All of our Leading Edge Sound Arrays come with #10-24 T-nuts inserted into VESA compatible 75mm x75mm mounting holes on the rear panel for easy wall mounting.
Our optional wall mounting system allows for a downward tilt of up to 14 degrees of the soundbar in order to direct sound just where the students are seated.
6 screws and your soundbar is installed.
MINIBar™
Give all your students a Leading Edge in listening and learning
Our MINIBar is perfect for slightly smaller rooms where stereo is not required but clarity and full sound is certainly desired. The MINIBar continues our signature sound but is designed and manufactured in a compact, very affordable package weighing only 11 lbs.
The MINIBar features VESA compliant attachment points for wall mounting and with our optional interactive panel mounting bars, it also can be mounted on a large TV/ display panel with 600 mm x 400mm VESA fly points.
Everyone and every Classroom deserves better sound
