These sit in different size classes, so this is not a straight ranking comparison. The Novacoustic KIRA 5 ranks #31 of 32 compact 5 to 6.5-inch pa speakers by sound quality; the Novacoustic KIRA 8 ranks #33 of 35 8-inch pa speakers by sound quality. Both are rated below 3.0/5 for their class (32 compact 5 to 6.5-inch pa speakers and 35 8-inch pa speakers), so if sound quality matters, look higher up the rankings.
Why pick the Novacoustic KIRA 5: A 6.6 lbs (3 kg) coaxial speaker with wide 90° conical coverage and a 16 ohm load that lets several share an amplifier channel. The tradeoff: Bass stops near 145Hz (-3dB) and the on-axis response is uneven (1.36dB average deviation), so vendor measurements give preference scores of -1.81 standalone and 2.17 with an ideal subwoofer.
The Novacoustic KIRA 8 is the more accurate, deeper-bass option. A compact coaxial cabinet with 96dB sensitivity, a 123dB peak and 90° conical coverage, with bass to about 78Hz at -10dB. Its measured preference score, a predictor of how neutral it sounds, is -1.23 against -1.81 for the Novacoustic KIRA 5. Its bass reaches about 118Hz before falling 3dB, against 145Hz for the Novacoustic KIRA 5. The catch: Preference scores of -1.23 standalone and 2.13 with an ideal subwoofer are low, because the listening window spreads across 7.7dB and bass rolls off at 118Hz (-3dB).
Buy the Novacoustic KIRA 5 for a compact 5 to 6.5-inch pa speaker, or the Novacoustic KIRA 8 for a 8-inch pa speaker instead.
