I have never seen or heard either, but a glance at both:
Both are low sensitivity, 85, 86, and those ratings are at 4 ohm, and 6 ohm. That requires more power, especially for instantaneous peaks. Not good for trying tubes which I prefer.
Don’t assume 1 larger woofer has more bass than two smaller ones, you have to hear them. Either model will want 1 or better yet 2 subs, in which case, look for a compact 3 way with ’enough’ bass. Higher efficiency (try tubes some day), higher impedance easier to drive.
both have rear ports. I'm not a fan of ports, if so, front to avoid the potential reflected sound from rear or side ports.
I would not consider either, but, if you or the wife had to have them, and I had enough power for 4 ohms, low sensitivity, I would order the 89’s, try to get return privilege’s just in case.
Visual Appearance: I’d rather have a slightly taller 3 way (tweeter at the top), positioned lower on a floor stand that tilts back so they don’t look large, but the tweeters are directed at ear height seated listening position.
KLH, others use this method, different slants, current production: 5 or 8 degrees based on what size model

this seller makes wooden ones for vintage Models, closer to the floor
