Introducing ShotPuck Two. (SP2) A 3-D printed, lead-shot-loaded record weight. The ShotPuck Two (SP2) is a record weight that features 5 chambers loaded with #9 lead shot. In fact 85% of ShotPuck Two's total mass is #9 lead shot. Each chamber contains precisely 65.2 grams of the shot. Total weight of the assembled record weight is 382.7grams (.84 lbs).
When it comes to ShotPucks, it really is all about the shot, because it is this mass of shot within each chamber that works to dampen the vibes running through the record as it is being played. It also helps that the puck material, ABS, has an acoustic impedance slightly lesser than that of vinyl which allows easy penetration of the vibes coming from the Lp into the puck.
It may not be pretty, but the sound quality improvement it can make is.
