PreSonus - 'Eris Sub8'

The best subwoofer for Eris monitors!Introducing yet another sonic succession from PreSonus, the ‘Eris Sub8’. The first subwoofer to join the celebrated and best-selling Eris family of monitors. PreSonus chose the name ‘Eris’ as it’s been designed from the ground up to be a complimentary member of the family. Sure, they play perfectly well with other monitors, but it’s when paired with Eris monitors that the Eris ‘Sub8’ really shines. The Sub8 is the best subwoofer around to put a little ‘boom in your room’!

All Work and All Play

ideal for the serious gamer!While PreSonus did indeed design the Sub8 to complement their smaller form ‘Eris’ media reference monitors, they also understand that gamers, partiers, and movie buffs alike all enjoy some room-rattle now and again.
So you can rest easy un the knowledge that the ‘Eris Sub8’ will seriously boost the performance of any powered speaker configuration in a home theatre or gaming rig!
Maximize your Frequency Response and Accuracy

shake the room! 30Hz - 50Hz!The shockingly loud 100-Watt ‘Eris Sub8’ drops down to a room-rattling 30Hz—a full 50Hz below the Eris 3.5s. This allows you to both rock harder and produce better mixes, as you’ll be hearing the true picture of your mix.
Notably, for EDM and hip-hop producers in particular, a sub is a necessity. The ‘Eris Sub8’ enables you to organically extend the reach of your Eris E3.5 or E4.5 monitors in a manner appropriate to smaller rooms; exactly where these monitors excel!
Total Control. Total Connectivity.

¼” TRS or RCA i/oThanks to robust configuration and I/O, you’ll be able to tailor your Eris Sub8 configuration exactly to your mixing and listening needs. You can connect your existing monitors via ¼” TRS or RCA, set the input level to your liking, and even invert the polarity. Most importantly, you get a High Pass Filter and a Low Pass Crossover control that ensures your Eris Sub8 starts working at the precise low-frequency point where your main monitors stop working.
This makes sure you avoid the flubbery, smudged, low-end mess that one hears in redundant, duplicate, redundant bass reproduction that occurs without a crossover!
