As kcarlile has pointed out, you might be better off using a pair of the on-wall W22s, which are essentially identical sounding to the M22s.
Whichever you choose, you'll find the Axioms are a huge upgrade in sound quality to the B&W LM1s. When I was editor at Audio magazine in New York, I had an opportunity to evaluate the LM1s. While in terms of industrial design, they are very attractive, the sound quality of the LM1 was quite colored and non-linear.
Any of the Axiom M2, M3, M22 (or their W wall-mount equivalents) you'll find are very neutral, detailed and transparent compared to the LM1.
