#23 O.S. Acoustics DBS8: $5,600/pair O.S. Acoustics Dealers eBay
Pros: The sealed MTM monitor reaches an estimated 48.5Hz at -3dB and has smooth directivity (2.80 SPDI standard deviation). It provides 650W of amplification per speaker, eight DSP presets, balanced XLR input, phase-corrected modes, and closely matched production tolerances.
Cons: The available Spinorama measurement is low quality and not from ASR or Erin. It is expensive, large, limited to analog XLR input, and its 105dB maximum SPL is modest relative to its size and amplifier rating.
How it compares: Just above it: JBL 708P - $1600 cheaper. Just below it: PSI Audio A21-M - $1880 cheaper.
