ProLinear 720 DSP - State of the Art Sound at an Affordable Price
The Alesis ProLinear 720 DSP sets a new standard in near-field monitors. With Alesis’ custom DSP technology, we were able to design a speaker with sound quality and accuracy that was not available at anywhere near it price. Clarity, imaging and transient response are truly outstanding. Bass is tight and visceral. We have compared the ProLinear 720 DSP to some of the most popular monitors costing many times more and its performance was considered superior by all listeners. In addition to outstanding sound, the ProLinear DSP’s 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. ProLinear 720 Features It Begins with the Drivers Any great speaker design starts with the best drivers and the Alesis’ custom drivers are exceptional. The woofer has a cast frame with a 7” Kevlar cone and oversized magnet assembly. The Kevlar cone has outstanding stiffness to weight ratio to minimize distortion, extend bass response and provide excellent transient response. The magnet assembly provides high linearity and good efficiency. In the 720 cabinet, the woofer is flat down to 43hz (-3db, anechoically) with harmonic distortion typically below .4% above 50hz. The tweeter is a 28mm silk dome that has a very flat frequency response with a low resonance to reduce harshness. The tweeter is ferro-fluid cooled to provide good power handling and well-behaved response. Distortion is typically below .3% over its operating range. The tweeters computer designed waveguide was optimized for near-field placement but provides excellent imaging in most other placements. Both drivers are shielded and allow the user to place the speakers within a few inches of a CRT. Specifications Input: Nominal input level: +4dBu (-15dBFS).
