What customers say about "Key Specs"
PreSonus Eris E8 8-inch, 2-way, High-Definition Active Studio Monitor
  • The speakers sound is strong, well balanced and puchy.
  • Great speakers... really compact, yet with a beautiful, balanced sound.
  • My first monitor speakers, and very, very pleased. Hooked up to my PC, and I can no listen to all my tunes without any distortion.
  • I dont have to move the main volume dial anymore then 30-40% they are very loud and clear with a good amount of bass Even with the room layout dial set to -4
  • After using the Eris 8s for a couple of months now, I have no regrets. Great sound, great frequency response, lots of volume to spare.
KRK RP8 G3 Studio Monitors - Pair
  • Great pair of speakers. Should have bought these years ago instead going through a few pairs of sub-standard monitors!
  • What? Whaaat? WHAA-? I can't hear what you're saying, my skull is friggin' caved in after turning this up to 50%.
  • They sound wonderful and achieve very loud volume levels when using a standard line level source.
  • The 8" version digs deep enough into the lower frequency range to provide adequate bass extension
  • As far as volume goes, because of the built in amps, you won't need any more volume.

KRK RP8 G3 Studio Monitors - Pair
  • These things are HUGE and very heavy. I'm a big fan of giant speakers
  • The 8's are very large for reference monitors! They fit snugly on either side of my computer monitor on a 48" wide desk.
  • I have a bigger size studio and the 5's were getting overwhelmed. Not these - they fill the entire studio beautifully without having to crank it all the way up.
  • These are much larger than one might expect if the specifications are not observed.
  • Overall body construction is also very solid and attractive looking

What customers say about "Audio"
PreSonus Eris E8 8-inch, 2-way, High-Definition Active Studio Monitor
  • Tonal balance is *really* nice for the size and price point; they're nearly as sweet as my much more expensive hifi speakers and amp downstairs.
  • Bass is pretty well controlled and tight, treble sparkly and detailed, and the mids clear and defined.
  • These speakers are amazing, how rich sound they have!
  • Can't believe the quality for the price. I wanted to have clarity and a flat, truthful sound. These give exactly that.
  • The sounds good in any frequency and the price is sensational.
KRK RP8 G3 Studio Monitors - Pair
  • Makes music a whole lot more enjoyable to listen to.
  • Cracking speakers they put orgasmic vibes into my ears with bass
  • I highly recommend these for people who enjoy all types of music and want a proper listen experience.
  • The bass will keep the squirrels off your roof and cause your uncle to have flashbacks of the war.
  • I bought 2. They don't sound good, they sound perfect. Outstanding imaging, like wearing really good headphones.

What customers say about "Features"
PreSonus Eris E8 8-inch, 2-way, High-Definition Active Studio Monitor
  • The adjustments on the back make it easy to tweak for your particular circumstances
  • Most impressed is the bass hole on the front side instead of back, so that means no early reflections if you set them close to the wall.
  • Adjustments for sound delivery; to tune to your taste.
  • I like the various adjustability features, a lot. They are very clear, and reasonably transparent.
  • Very impressed with this speakers sound and diversity in settings and inputs for various needs.
KRK RP8 G3 Studio Monitors - Pair
  • Absolutely stunning full sound. Turn off intelligently when not in use.
  • They aren't warm and fuzzy speakers. They reproduce sound the way it was originally mixed and allow you to make great mix downs.
  • They are really nice speakers. The bass sounds tight and accurate, with the dial set at 0 the low frequencies are quieter than my audio technica m50x headphones.
  • I keep the knobs at zero, to try to get as close to flat sounding as I can and adjust the eq in my computer.
  • These speakers offer a decent amount of tweaking (Lows and highs sensitivity) on the speaker itself
