K.I.S.S. Sonic Vortex Speakers Rock All Night and Every Day

Keeping It Super Simple is entering the market through a newly launched crowd funding campaign.


In many ways the electronics industry represents a confluence of many forces. Driving this is increased consumer demand for home entertainment, a new era of digital technologies and a competitive market place that thrives on manufacturer competition.

Arguably no category better represents this confluence of electronics prosperity than loudspeakers. The latest manufacturer to throw its hat into this market competition is Keeping It Super Simple (K.I.S.S.). Launched by long-time industry veteran Jim Murray, this new audio company is entering the market through a Kickstarter campaign and an attractive early-bird deal to finance its operations.    

Murray, a speaker designer who gained notoriety for his Sonic Vortex technologies, is bringing this design element to a reasonably priced product line that makes its debut with the X4 2.1 on-wall speaker system.

The company says the on-wall speaker system is designed to meet current market demands in which homeowners desire an immersive audio experience without the addition of large multichannel audio systems into their interior spaces.

Implementing his Sonic Vortex technology, Murray’s company says the speakers “can fill any room with 3D-style sound from any audio source with no special electronics or multichannel audio content required.”

K.I.S.S. states the X4 loudspeaker incorporates a ¾-inch tweeter and a 4-inch midrange driver. The X4’s companion subwoofer utilizes a 6.5-inch woofer. The X4 also incorporates a 24-bit/96kHz digital-to-analog converter (DAC), along with a 60-watt Class D amplifier. A 100-watt amplifier drives the subwoofer’s 6.5-inch woofer, and it also includes a 5.8GHz wireless connection option to mate to the X4 speakers.

The Orlando, Fla.-based startup company also points out the subwoofer is rated to deliver sound pressure levels (SPLs) as high as 104dB, and the entire system’s frequency response is rated at 26Hz to 22kHz.

In addition, system connection options include digital coax, analog line level and wireless Bluetooth 4.0 with AptX.

Early-bird participants can purchase left and right X4 speakers for $199.
