Yup, those older electronics (hold onto your hats, folks) do have a different sound. Personally, I like the more precise sound these days, but I have noticed the thing you speak of. To be fair, it was many years ago with substandard speakers, but... A sub should solve all of your problems. From what I've personally heard, an SVS PB1 matches the 22s quite nicely.
