HK Audio Linear 5 MK2 308 LTA vs Bose AMM108

The case for the HK Audio Linear 5 MK2 308 LTA: Part of HK Audio’s LINEAR 5 MK II series alongside the HK Audio Linear 5 MK2 112 FA: a long-throw top with three 8” woofers whose asymmetric vertical pattern reaches about 40 meters. The catch: No independent measurements yet, so it can’t be compared with ranked PA speakers.

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. The catch: 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 HK Audio Linear 5 MK2 308 LTA. It is rated higher for sound quality than the Bose AMM108.

Same family: the HK Audio Linear 5 MK2 110 XA (smaller model, estimated 3.6/5), the HK Audio Linear 5 MK2 112 FA (smaller model, estimated 3.7/5), the HK Audio Linear 5 MK2 112 XA (smaller model, estimated 3.7/5), the HK Audio Linear 5 MK2 115 FA (smaller model, estimated 3.6/5) and the HK Audio Linear 5 MK2 115 XA (smaller model, estimated 3.5/5). See every HK Audio Linear 5 generation.

Pros: Part of HK Audio’s LINEAR 5 MK II series alongside the HK Audio Linear 5 MK2 112 FA: a long-throw top with three 8” woofers whose asymmetric vertical pattern reaches about 40 meters. A 1,200W peak (600W RMS) bi-amplified Class D module with DSP drives it, and HK rates it at 138dB peak with 60° horizontal, asymmetric vertical long throw coverage.

Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. Bass stops around 105Hz, so it must be paired with subwoofers.

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.
