I have 2 Ascendant Audio Arsenal Subs that are brand new. These have been out of the box to inspect and take pictures only. Comparison wise theese would fall between a JL Audio W6 and a Image Dynamics IDQMAX.
The Arsenal Series of subwoofers starts with a monster triple stack motor supported by a lightweight and durable cast aluminum frame. The 2.5" diameter voice coil using aluminum round wire for a durable, yet light assembly, handles 500W RMS. Utilizing dual linear spiders, a fiber reinforced kraft pulp linear profile cone, and a durafoam surround, the sub is tough as nails. Sitting at our mid level, the Arsenal Series has the durability, sound quality, and output equivalent to many companies high line drivers.
