I think the biggest reason is that the price point is quite close to the Alesis Strike. With the Alesis Strike being the superior kit, more drummers gravitate toward buying that instead of the DM10. The other reason is that all of the Alesis kits that cost under $1000 are incredibly popular. The Alesis Nitro Mesh is a top-seller around the world as it’s one of the most affordable beginner's electronic drum sets. These cheaper kits are simply more popular than the DM10 as there’s a larger pool of buyers for them.
