List of upgrades compared to the v1 SA series (Rev.1,2,3):
- Magnet outer diameter increased from 180mm to 190mm
- Magnet slugs increased from 25mm to 27mm in height (total 4mm more height)
- Motor structure fully bolted together with 3x M6 bolts (eliminates the possibility of motor shifting)
- Top-Plate “Slits” implemented as with the X and Z series. Increased cooling & reduced distortion.
- Improved gap venting — more / flared gap vents.
- Improve pole-vent design — smoothly flared on both sides.
- Coil increased from 63.5mm (2.5″) to 70mm (2.75″) in diameter. Higher thermal capacity.
- New “U series” style cast-aluminum frame for taller cones (more x-mech both top-side from cone to spider and bottom from spider to top plate)
- Aluminum cast gasket to bolt-on surround.
- Aluminum cast vent ring to enhance thermal transfer from motor to the frame.
- Standard with double “XL” leads and “bolted-on” spider
- Larger and thicker surround (same tooling as U series).
- Strongest paper cones we have ever produced… new two-piece mold technique.
- “Large Flange” dust cap just like our larger woofers. Essentially eliminates dust-cap glue failure.
- Larger spider diameter on the 12/15″ models (the 10″ retains the same 188mm spider)… 12″ up to ~200mm and 15″ up to ~210mm
- Improved spider material for longer life.
