memphis VS kicker

im throwing around ideas for subs and wondering how these 15" kickers would match up against these 15" memphis.

memphis: http://www.sonicelectronix.com/item_9570_Memphis+15-PR154D.html

i noticed the magnet size on the memphis is like half the size of the kicker....

Ya, the magnet is much, and if you notice, the memphis only take 1/2 the RMS power. And personally, as a rule of thumb, I woudlnt get any speakers with designs in the surround. Its just a "me" thing (lol). However, I woudlnt get the mephis either. But, if your on a budget and thats all you can get, much better than nothing.

you can go on ebay and get 2 kicker L5 12'' subs for like 260 plush shipping like 300, they r insane subs, 1200 watts each sub..

I would look into the following if I were you:
RE, FI, ID
They all have REALLY good subs, and decently priced.
Of course, it depends on what kind of sound you are looking for.
SPL (loud) or SQ (sound Quality)
The above brands have both in one at an unbeatable price.
