I have only heard Maggies in stores but I owned a pair of La Scalas for a couple of years. They are extremely dynamic speakers that can give a feeling of listening to live music. The bass doesn't go extremely low but it is very quick and realistic sounding. Depending on the room, you can probably get usable bass response into the mid to upper 40's. I put Bob Crites crossovers and tweeters in mine and it really opened up the sound, but the crossovers had 30 year old capacitors in them, so it was time for replacement of those parts. They really like a big room, the bigger the better, although I thought they worked well in my 21 x 12 foot room. The downside, other than the shear size of the suckers, is they are bright in the upper midrange/lower treble region. Some folks seem more sensitive to this than others. Also, they don't do detail as well as many modern designs. I never heard them with tubes, but many say they really shine with low power tube amps. Oh, and if you like to tinker, there are a million things you can do to them to tailor the sound to your liking. Kind of reminds me of the muscle cars of my youth -- no one ran them stock. Definitely a different experience than your Maggies.
