Short answer: the RCF ART 708-A MK5. It ranks #26 of 44 8-inch pa speakers by sound quality (rated 3.4/5); the Bose AMM108 ranks #33 (rated 3.2/5).
The RCF ART 708-A MK5 is the deeper-bass choice. A compact, affordable RCF with a 1.4-inch compression driver, 128dB claimed output and FiRPHASE processing, well suited to buyers who plan to cross to a subwoofer and do not need app control. Its bass reaches about 75Hz before falling 3dB, against 87.5Hz for the Bose AMM108. Watch for: The local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain.
The case for the Bose AMM108: High-quality manufacturer measurements show a smooth on-axis response (0.76dB average deviation), and the compact wedge cabinet doubles as a fill or floor monitor with 110° x 60° coverage and a 128dB peak. Watch for: Preference scores of 1.09 standalone and 4.34 with an ideal subwoofer are low because the listening window spreads across 4.4dB.
Buy the RCF ART 708-A MK5. It is rated higher for sound quality than the Bose AMM108.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.

Bose AMM108 Passive B&H eBay
Same family: the Bose AMM112 (larger model, rated 3.3/5).
Pros: High-quality manufacturer measurements show a smooth on-axis response (0.76dB average deviation), and the compact wedge cabinet doubles as a fill or floor monitor with 110° x 60° coverage and a 128dB peak. Measured bass extension of 87.5Hz (-3dB).
Cons: Preference scores of 1.09 standalone and 4.34 with an ideal subwoofer are low because the listening window spreads across 4.4dB. Bass reaches only 88Hz at -3dB, so it needs a subwoofer for music. It is passive.
