Is Presonus still making and shipping out the Temblor T8 subwoofer?

After purchasing my Presonus ERIS E5's, I have since been getting no where in trying to purchase a new Temblor T8. It seems that all the suppliers here in Canada have no stock! So my conce is...does anyone know if Presonus is still making and shipping out the Temblor T8? I really would like to have the matching sub for my ERIS E5's, and do not want to have to retu them and go with another brand. The Presonus speakers have a great sound!

Thanks
