TECH TALK

Our three-way systems are designed around the concept to distribute the frequencies properly between all individual components and raise the efficiency of your speakers effectively.

In our three-way systems, each driver (woofers or tweeter) gets its own amplifier. One of the woofers serves frequencies up to 300 Hz as a kind of "bass" whilst the other woofer gives you a fuller range as a bass-midrange driver, up to the 3000 Hz crossover frequency. From that frequency on, our AMT tweeter takes over. This minimizes interference between the drivers and also allows the SC307 to deliver a very efficient and dynamic sound reproduction.

What this design philosophy means is that less effective physical work is being made by each individual woofer, as the band of frequencies to be reproduced are divided between both woofers. This in turn will result in less mechanical inertia and a more efficient sound transmission.

Both woofers consist of our proprietary 6.5" SilverCone, the same that is used in our two-way system, the SC207, and features our sophisticated low distortion copper cap magnet system. However, due to the fact that two of these woofers are being used simultaneously, you get a bigger frequency response down to 40 Hz.

The SC307 also makes use of the proprietary AMT RS2 tweeter, which uses a bigger front plate, and a bigger internal magnet to drive the AMT tweeter with greater efficiency.

The three 100 W PWM power amplifiers won't leave you lacking any power either, as the maximum sound pressure level of 114 dB (SPL @ 1m) will attest.

And no worries determining how to place the SC307 in your room or studio properly. Our DSP section will assist you in choosing the speaker for left and right hand side. So you will always get proper symmetry between your speakers, instead of having to move them around as usually. With a DIP switch located, on the rear of speakers these settings for room adaption can be temporarly locked.

As with every other EVE Audio speaker, you get both balanced XLR inputs and unbalanced RCA inputs for greater convenience. 

DSP / SMART-KNOB

All EVE Audio monitors feature a high-resolution DSP electronics. A high-quality analog/digital converter from BurrBrown (24bit/192kHz) converts the analog input signal supplied via RCA or XLR. The DSP provides latency-free filtering while protecting tweeter and woofers against overload across the entire frequency range. When switched on, the volume of the monitor increases slowly to leave enough time to reduce the source volume if the input signal is too loud.

Adjustments to the acoustic environment can be made via the front rotary/pressure encoder, the SMART-knob with rotating LED ring. This knob allows the levelling of system volume as well as the adjustment of filters for room variables (low shelf, mid eq and high shelf filters). All settings are displayed on the LED ring, providing instant information about the selected values. The brightness of the LED ring can be adjusted for dark studios or video applications.

High-quality Class D amplifiers complete the system and deliver enough power to the demands of modern music production. Selected volume and/or filter settings can be independently fixed with DIP-switches that are positioned on the rear of the amplifier to prevent unauthorised or unintentional adjustments. 

BASS PORT DESIGN

The rear-facing bass reflex channel is, as usual with EVE Audio, designed for low airflow noise and enhances the powerful and precise bass reproduction.
