K231 3-Way Active Crossover

 Stereo 3-way active crossover for Bi-Amping or Tri-Amping your sound system

 Active crossovers are used to significantly improve the audio quality of your sound system by separating the high, mid and low frequency sounds and using a separate power amplifier for each speaker driver. This is called Bi-Amping or Tri-Amping.

 Virtually all professional grade audio gear built in the last 30+ years have used ‘Electronic Active Crossovers’ in place of passive crossovers. There are many reasons for this, but the biggest reason is the quality of the sound they produce.

 Passive crossovers destroy the quality of your sound and steal half of power from your amplifier. And that’s just the beginning of a long list of evils perpetrated by these antiquated devices.

 Though Bi-Amping has long been ubiquitous in the high end pro-audio market, the consumer audio market has largely avoided any moves it that direction.  Bi-amping has historically been considered too expensive for the consumer audio market due to the high cost of electronic active crossovers and the need for extra amplifier channels.

 But that’s rapidly changing due to the availability multi-channel amplifiers at reasonable prices and the introduction of lower cost, high quality Electronic Active Crossovers, such as the Sublime Acoustic K231.

 Comparing the current cost of Bi-Amping to the cost of today’s high end passive crossovers, where capacitors alone can run into the hundreds of dollars, Bi-amping is actually now the lower cost and higher quality option today.

 Anyone who’s heard a good Bi-Amp or Tri-Amp system understands the level of sound quality that can be achieved.

 Several people have commented that to us that after converting to Bi-Amping, their systems sound as good as $25K+ systems, and at a small fraction of that cost.

 The first thing you’ll notice is a quite dramatic improvement in sound stage clarity and definition. You’ll begin to hear detail in your music that was previously sub-audible. You’ll notice a widening, deepening, and increased definition of the audio image. Becoming so detailed you can pick out and locate every instrument on the stage.
