Sound Quality

The Eris Sub8 and the Temblor T10 are designed to deliver accurate and powerful low-frequency reproduction. 

The PreSonus Temblor T10 features a bass-reflex enclosure and a 254mm 10 inches composite woofer protected with a metallic perforated grill. The total harmonic distortion (THD) of this subwoofer is 0.019%.

With a top leading sound pressure level (SPL) of 113 dB and frequency response of 20-200 Hz, PreSonus Temblor T10 has an out-class sound profile. Even at maximum sound levels, the distortion is minimal.

On the other hand, we have the PreSonus Eris Sub8. This active front-firing subwoofer has a 20.3cm 8 inches composite woofer with a total harmonic distortion (THD) of 0.05%.

The small differences in numbers might not surprise you, but these make the most of the differences. Especially Presonus Temblor T10 can deliver slightly lower bass frequencies, which may result in a more extended and immersive bass experience, especially for movies or music genres that require deep bass performance.

Amplifier Output

Since the PreSonus Temblor T10 and PreSonus Eris Sub8 are active subwoofers, they feature a built-in amplifier. The PreSonus Temblor T10 features a Class-AB-rated amplifier having 250W peak power and 170W RMS power rating.

In Direct Current (DC), the amplifier’s power consumption is 100-120 volts with a frequency response of 50/60 Hz. In contrast, the power consumption in Alternating Current (AC) is 220-240 volts with a frequency response of 50/60 Hz.

On the other hand, the PreSonus Eris Sub8 also features a Class-AB-rated amplifier. This built-in amplifier has a peak power of 50W 100W RMS power rating. This amplifier gives minimal distortion even after hours of continuous use.

The output is almost identical since both front-firing subwoofers have the same built-in amplifier.
