Tweekerman: The REL Storm III is not a good match for the N802. The N802 is in another (higher) class than the Storm. Won't make much of a difference. I am not surprised he did not like it. But instead of giving up he needs to think higher.
Your friend needs to consider at the very least the REL Stadium III or even better the REL Stentor III. The Storm III is fine for the B&W N804, N805, CDM Series, or the Matrix 804 and 805.
I love my REL Sub. Would never go without one again.
