I've been using an Eden 410 XLT for the last few years, and have been happy with it. However, I've come across a used Eden 410 XST, and wondered if anyone has any thoughts on the latter. According to the Eden web site, the XST is a bit shorter (25" vs. 27.5"), goes lower and deeper (36 Hz) than the XLT (50 Hz), and is a bit lighter (95 lbs.) than the older XLT (98 lbs.). I'd really appreciate any "feedback" from anyone who's had a chance to compare the two side by side. Thanks.
