ART CX311 Stereo 2-Way Crossover with Sub Out

The ART CX311 crossover may be used as a stereo 2-way crossover network and has the addition of a subwoofer output for low-frequency reinforcement. It employs 24 dB/octave state-variable, fourth-order Linkwitz-Riley filters that guarantee properly phased outputs at all frequencies, which is optimal for the proper acoustic summing of common signals from adjacent drivers in the crossover region. Each channel features independent high and low output level controls and a crossover frequency rotary control which covers a wide range (250 Hz to 6 kHz). All three outputs have a 30 Hz low cut switch to eliminate low-end rumble. The subwoofer features an independent output level and rotary control for frequencies in the 50 Hz to 250 Hz range.

Specifications: • Frequency response: 10 Hz - 40 kHz, ±.5 dB • Max input level: +21 dBu • Max output level: +21 dBu • Signal to noise ratio: >95 dB, 20 Hz - 20 kHz, unweighted • THD: <0.01% • Dimensions: 1.75" H x 19" W x 5.5" D • Weight: 4.85 lbs.

ART CX311 Stereo 2-Way Crossover with Sub Out
ART CX311 Stereo 2-Way Crossover with Sub Out is rated 4.3333 out of 5 by 6.
Rated 4 out of 5 by from Great for driving additional SpeakersI bought this for the sole purpose of driving and additional pair of tweeters only. (Also purchased at Parts Express).For these tweets I set the crossover to 4k.I like the idea of the sub-out control also.I plan on eventually driving the sub-amp from here also.

Rated 4 out of 5 by from sounds good....frequency label is off thoughNo hum even with very high sensitivity speakers, good sound. BUT...don't trust the numbers on the dial for crossover frequency. On my unit both channels match but are way off. for example: I wanted 500hz, when measured that position was more like 200. run some tones to set your xo freq.

Rated 5 out of 5 by from Very capable toolI use the unit to bi-amp a set of Altec 605As from the early 1960s, crossing at 1600hz. The unit does the job intended with no noise or fuss and with clear, transparent sound.Very easy to use too, simple. I like simple.

Rated 4 out of 5 by from 250 hz CrossoverThis crossover works for my two channel system. I have a relatively musical sub and so I set the sub to 120 hz and below. Then I have the ART 311 crossing at 300 hz. I realize that I am loosing frequency between about 120 and 300, but my goal was for my monitors to cross at 250 or so. The ART 311 met my requirements but if you should not buy it, if you want to fine tune your frequency range below 250.

Rated 4 out of 5 by from Very clean, limited flexibilityI've seen Behringer x-overs last years, but seeing that the ART was basically same cost, why not go with a more reputable brand? Out of the box, it's solid, all knobs consistently smooth and solidly braced; well-built. Certainly heavier and more rugged construction tha Behringer.Sound is clean, very clean, and even at low signal input level, there very little noise.Gripes: 1. balanced ins, yea, unbalanced outs only, booo. 2. I should have looked more carefuly - you can't use this as to split sub freqs from those of a full range mains; It expects that your mains always require bi-amping as the x frequencies aren't quite broad enough. If you change mains depending on the gig, this unit may not give you the flexibility needed.Overall, first impressions are it's a great piece of gear with limited flexibility.

ART CX311 Stereo 2-Way Crossover with Sub Out

HF driver protection... what can I use for HF driver protection along with this ART CX311 since I no longer use a passive crossover with bulb fuses.

This active crossover is being used in a bi-amped 700 watt PA for my 3pc. band.The High Freq. amplfier is a QSC GX3 ....
Asked by: DMSLV
You can still use a lamp even in a bi-amp setup for tweeter protection. There are a few choices. I have listed one below.

Is it suitable for home audio application?

For example for a 2 way bookshelf?
Asked by: kamaruj
This product is intended for pro sound applications, but there are some that do use pro gear in a home setting. The main concern to be careful of is there is a difference in signal level between home gear and pro gear. Home runs at a much lower signal level than pro.
