The Malibu Boats Wakesetter 21 LX-R 2023 vs Malibu Response LXi 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Malibu Boats Wakesetter 21 LX-R 2023 at 21,0 ft versus Malibu Response LXi 2011 at 20,5 ft. Weight tells a clearer story for trailering families: the Malibu Boats Wakesetter 21 LX-R 2023 tips the scales at 4 580 lbs — 4 554 lbs more than the Malibu Response LXi 2011 at 26 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 410 hp, the Malibu Response LXi 2011 has a 50-hp advantage over the Malibu Boats Wakesetter 21 LX-R 2023's 360-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
