4 verified differences, led by Manufacturer speaker channel layout, manufacturer audio-interface declarations and manufacturer total audio output and rating basis. Compared in full below. Not a rating.
The HS8 is a single powered two-way studio monitor with a 8-inch cone woofer and 1-inch dome tweeter, bi-amplified at 120 W (dynamic power). It takes balanced XLR or 6.35 mm phone-jack inputs and is sold as one cabinet, so a stereo pair means buying two.

How to read this comparison
Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.
