The AC-One Controller is a combination of newly-patented PowerMax crossover filter an unusually flexible, three-band EQ a continuously variable infrasonic filter EV's LPN bass/dynamics processing. The AC-One is designed for use with sound systems that use two-way speakers, plus subwoofers. Its excellent audio performance, dynamic range of 117 dB, extremely low noise level, and outstanding price-performance ratio make the AC-One Controller an great alternative to conventional crossover and controller solutions.

The BBE® Max-X3™ is a highly sophisticated 2-way stereo/3-way mono crossover. Housed in a compact and easy-to-use package, it provides a variety of options for virtually all live sound reinforcement amplifier configurations. Max-X3's logical design makes it simple to understand and easy to use, and its sonic integrity promises clean, distortion freeaudio with a predictable, repeatable range of control.

Let’s take a look at the construction features of the dbx® 234XL. At first glance you’ll notice the units are great looking, and as you turn the controls something else becomes apparent; these units are extremely well built. The controls exude great precision, and the feel is a solid “click”. Also, when you open the box, you won’t find the external power supply that accompanies most processors in this price range. That’s because we know how difficult external power supplies can be to work with and even though it costs a little more we put the high quality power supply right in the unit. All the inputs and outputs are balanced XLR connectors that are screwed directly to the chassis. This connecting of the jacks insures that even if someone steps on a cable plugged into the unit, it’s not going to tear up the circuit board inside. All dbx crossovers feature Linkwitz-Riley 24dB per octave filters, the professional standard, but then again, what did you expect?

Let's take a look at the construction features of the dbx® 223. At first glance, you'll notice the units are great looking. As you turn the controls something else becomes apparent; these units are extremely well built. The controls exude great precision, and the feel is a solid "click". Also, when you open the box, you won't find the external power supply that accompanies most processors in this price range. That's because we know how difficult external power supplies can be to work with and even though it costs a little more we put the high quality power supply right in the unit. All the inputs and outputs are TRS differentially balanced 1/4" jacks that are bolted down to the chassis. This "nutting down" of the jacks insures that even if someone stomps on a cable plugged into the unit, it's not going to tear up the circuit board inside. All dbx crossovers all feature Linkwitz-Riley 24dB per octave filters, the professional standard. But then again, what did you expect?

The S 3-way is a versatile 2-way, 3-way and 4-way crossover with a difference. First, it's a perfect 2-way or 3-way stereo crossover. But its mode is also switchable for use as a 4-way mono crossover.
