used one in my friends HT setup, very nice for the price. Much like the ED subs. Somewhere in between the Kv.2 and Ov.2. I am assuming you're shane m from ICIX so you know how the ED subs are. A few of my customers have bought some and never heard any complaints from them.
RL-p is a better version of the Ov.2. Ov.2 lacks a good solid bottom end. It(16Ov.2) was most peaky in a 2.2cu ft tuned to 28hz was most peaky at 55-67hz, i thought that was strange. It didn't do well in the 32hz and below, well not as well as the Rl-p or my Mag does. I would go with the RL-p. And as for the Arsenal, from talking with a AA user of the Ava's, the Arsenal aren't that good compared to the older one and I thought so too. The new Havoc's may be quite good but haven't heard one yet. I'm not even sure where the Arsenal lies in the AA series cause they only have the atlas and ava before and now they have 3( assasin, arsenal, havoc). But with Dayton as long as you get the HO or the NKIII and use in car setups they'll be very nice for the price.
