Price and rating as shown on Amazon when we collected them. Both change.
The PreSonus Eris 3.5 Gen 2 is at number four in this guide. It is a powered desktop pair — two cabinets, sold together — with a 3.5-inch woven-composite woofer and a 1-inch silk-dome tweeter in each one, a class AB amplifier rated at 25 W per side, and balanced 1/4-inch TRS, RCA and front-panel aux inputs. The listing price is £79.00 for the pair, and the rating sits at 4.6 out of 5 from 425 ratings.
The spec table is where this listing trips over itself. It files an 8-inch subwoofer diameter against a speaker whose woofer is 3.5 inches, gives the frequency response as 80 Hz in the table while the bullet directly above it says 80 Hz–20 kHz, records the control method as "Touch" when the same page describes a front-panel volume control with high- and low-frequency tuning on the back, and lists the water resistance level as "Waterproof" one field after stating the product is not waterproof. The one figure that does close is the power: 25 W per side across two cabinets is 50 W, which is exactly what the headline claims. Everything on this page comes from the Amazon listing, not from testing we carried out.
How those 425 ratings break down

Questions people ask
Does the PreSonus Eris 3.5 Gen 2 come as a pair?
Yes. The listing says it is sold as a complete stereo pair, so the £79.00 price covers both speakers rather than one.
What size are the drivers?
Each cabinet has a 3.5-inch woven-composite woofer and a 1-inch silk-dome tweeter, according to the PreSonus listing.
Is there an 8-inch subwoofer?
No. The spec table has a subwoofer speaker diameter field reading 8 inches, but the same listing describes a 3.5-inch woofer and 2.0 audio channels, and no subwoofer is mentioned in the box contents.
What is the frequency response?
The bullet says 80 Hz–20 kHz. The spec table's frequency response field reads only 80 Hz.
What can I plug into them?
Balanced 1/4-inch TRS, RCA and a front-panel 1/8-inch stereo aux input, plus a front headphone jack. The listing records no wireless connectivity.
How are they powered and controlled?
A class AB amplifier at 25 W per side. Volume is on the front panel and the high- and low-frequency tuning controls are on the back — the spec table's control method field instead says "Touch", which does not match the copy.
