ProLinear 820 DSP - State of the Art Sound at an Affordable Price

The Alesis ProLinear 820 DSP continues the new standard in near-field monitors that was set by the ProLinear 720 DSP. With the same Alesis' custom DSP technology, we have designed a speaker with same sound quality and accuracy but with extended bass and greater output. This allows the speaker to be used as a mid-field monitor as well as near-field. As with the 720 DSP, the internal processing allows user flexibility to configure the speaker for almost any application via the front panel control or the included graphical PC application software.
