#8 PreSonus Eris Sub 8BT: $209.99 Amazon eBay
Pros: Independent CEA-2010 testing records 77.7 dB at 20 Hz and 111.3 dB through 40-80 Hz. The ported enclosure with an 8” driver suits a small room or desktop-adjacent setup.
Cons: Warranty is a below-average 1 year. The 297.9H x 249.9W x 323.1D mm cabinet and 7.4 kg mass still need deliberate placement.
How it compares: Just above it: Sony SA-CS9 - $10 cheaper, 1.4dB more max output. Just below it: Velodyne Acoustics SPL-1200 Series II - $289 more.
