Quadraspire Q4L is an extended depth version of the Q4 Evo. It does have thicker shelves, and has depth and strength suitable for full sized McIntosh Amplifiers.
original Q4 style shelf (no underside milling)
same column variety as Q4 Evo
23.24” x 18.5” outside dimensions
19mm columns per shelf
configures identically to Q4 Evo
This is a terrific solution for those with larger stereo equipment. They also make nice large amplifier stands if you get a single shelf with foot/top. If you find you move your amplifiers/equipment often, getting single shelves of these with optional casters is, uh, convenient.
