BasX: The Foundation of a Superb Audio System

A great audio system starts with quality components that deliver excellent technical performance with superb sound quality. When you break it down, audio components don’t need to have a lot of fancy features, complicated controls, or unnecessary bells and whistles to perform exceptionally. If sound quality, flexibility, and performance are your goal, the new Emotiva BasX is for you.

BasX is value, simplicity, and sound quality – streamlined. Every product in the BasX line combines excellent performance, exceptional sound quality, and true value. It may not have crazy bells and whistles, or be made of rare materials, or have jewelry-like finishes, but it’s clean and rock solid. And in our opinion, it’s beautiful too.

Every BasX component is designed from the bottom up to sound and perform flawlessly. You don’t need to be an engineer to set it up, or a fortune to own it. BasX brings the “high end” to everyone.

You can build music system out of our BasX components that will give you years of enjoyment, along with every bit of the sound quality you expect from a true audiophile component. Try adding one or two BasX components to round out your existing audio system. You’ll be pleasantly surprised.

BasX Features

The BasX offers all the essential features that make a great audio component. The circuitry in the BasX A-300 features a heavy duty linear power supply, great sounding high-current short signal path Class A/B amplifier modules, a trigger input and output, and industry standard unbalanced audio inputs. It also includes audiophile-quality fault protection that’s completely transparent in normal operation, yet protects the A-300 and your other equipment from common fault conditions.

BasX Performance

The BasX A-300 delivers real audiophile sound quality – and we’ve got the specs to back that up: 150 watts RMS per channel at less than 0.1% THD into 8 ohms; THD+N of less than 0.02%; and a signal to noise ratio of 120 dB referenced to full power.

BasX Simplicity

While the BasX A-300 offers lots of performance, you won’t need a Ph.D. to install and use it. Just plug the BasX A-300 into any standard 115 VAC or 230 VAC line; it will figure out the correct voltage to use. A removable heavy-duty power cable is included, and, if you want to experiment with power cords, the BasX A-300 also accepts any industry standard IEC power cable. The speaker outputs are heavy duty five-way insulated binding posts that work equally well with bare wire, banana plugs, or spade lugs.

BasX Quality

The BasX A-300 is built to last, with a heavy duty steel chassis, solid milled aluminum faceplate, and high-quality parts and construction… We expect you to enjoy your BasX A-300 for a long time – and we back that up with a full three-year warranty.

The BasX A-300

The BasX A-300 is a two channel power amplifier. You can use the BasX A-300 for an excellent stereo sound system, or to run two channels in a home theater system or anywhere a great sounding two channel power amp is needed.

Exceptional sound quality. Excellent value.
