This is great. I have been trying to buy a sundown ns1 v2 and cant seem to find one from an authorized dealer.they stopped production for a couple i aas told by wooferect.com the. My other choice was a dc 7500.1 but have not heard barely anything about fustomer service. As this will be the 3rd most expensive thing i have ever bought and i make $8.00 an hour that is pretty important. Seeing the owners on here makes me feel good.
