I can't comment on the wall version, but I had the Micro Walsh Shorts (which are 22" tall) and have also heard the Micro Walsh Talls at my friend's house. The shorts do loose a bit of low end to the talls, but not much. I believe the wall mounts loose even more in the low end as they are shorter still. Both those I've heard have similar characters and are fun and engaging. I used the shorts as desktop speakers for my computer and they were great for that purpose. They disappeared like Caspar, even in nearfield. WAF? I guess it depends on the wife and on the decor you are trying to blend them with. They looked fine to me and I'm pretty picky. They are nicely finished (mine were black and my friends are cherry. They do require some power to sound their best. In my case the shorts sounded better with 100 watts than they did with 50 so the extra 3db of headroom helped (different amps to be fair though). Most folks who are using them as dedicated speakers choose the talls for the fuller range. In researching them I could find very little input on the short versions.
Hope that helps.
