Smaller models: the MartinLogan Motion F10 (ranked lower, estimated 3.8/5) and the MartinLogan Motion B10 (rated 3.6/5).
Pros: Larger 6.5-inch dual aluminum woofers provide greater bass depth down to 35Hz and increased dynamic headroom for larger rooms. Wide horizontal dispersion and crisp transient response from the Gen2 Folded Motion tweeter.
Cons: Noticeable treble energy elevation requires careful acoustic matching or gentle toe-in. Substantial physical footprint and height.
