#48 Miller & Kreisel S-150 THX: $750 each Discontinued eBay
Newer model: the Miller & Kreisel S150, ranked higher, rated 4/5, released 2018. See every Miller & Kreisel S generation.
Pros: The mid-1990s original of M&K’s studio and home theater LCR, with the same three-tweeter vertical array and twin woofers as the current Miller & Kreisel S150. Audio Science Review measured a flat on-axis response, low distortion and good power handling, and a score of 7.19 with an ideal subwoofer, almost identical to its successor. Measured bass extension of 112.8Hz (-3dB).
Cons: Discontinued and found only used, often with deteriorated tweeter foam. Off-axis output drops above about 800Hz and vertical directivity is uneven, so its standalone score is 3.94, and bass falls to -3dB at 112.8Hz, so it is meant to be used with a subwoofer. Audio Science Review also found a resonance near 5kHz.

Frequency Response
How the Miller & Kreisel S-150 THX measures across the audible range. A flatter listening window (the sound arriving straight at you) is more neutral: peaks sound forward or harsh, dips sound recessed. The estimated in-room response adds what a typical room does, and there a gentle, even tilt down toward the treble is ideal. Both curves are shifted so their 300 Hz to 3 kHz average sits at 0 dB.

EQ for a Neutral Response
No EQ preset: the best simple EQ we can fit to these measurements improves the predicted preference score by less than 0.2. The listening window is already close to flat, and what holds the score back, such as narrow ripple in the response or uneven output off-axis, is not something EQ can fix without making it worse elsewhere.
