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

With every EVE Audio speaker, you also get high resolution DSP electronics. One push knob operation and you will have access to accurate volume control and several different filter settings that will help you tailor your monitors to the way you work. And if you always avoid digital processing, we've got you covered. The DSP engine is supported with a high quality A/D converter (24bit/192kHz) from Burr-Brown, which delivers a pristine signal to the DSP section. And since the PWM amplifiers are directly connected to the DSP, no additional conversion is necessary. Please visit our DSP page to learn more about our DSP philosophy.

Bass Port Design

It's all in the geometry. One of the downside effects of port compression is bass distortion. As you turn up the volume, the efficiency of the port reduces and distortion will increase.

We opted for a large rear rectangular port with no hard edges for our bass port designs. That's one of the reasons EVE monitors have a high efficiency on the lower frequencies.

The results? High sound pressures with tight and punchy bass frequencies that don't cause port distortion. Crank up the volume, and EVE will deliver a round bass. And with no holes to look at every time you glance at your speakers.
