WOW. I'm speechless
Now, to start off, I've owned a lot of different subwoofers. I usually stick to two tens and that's what I did with the W260D4s. This is the first pair of 10s I've bought from a name brand (i.e. pioneer, kicker, Kenwood, blah blah blah) This product... simply blows all the others I've had away, maybe it's the air pressure inside my car that blows them away (ha.) Dang though these are loud. I put these two subs in a 1.6 cubic foot sealed box (Recommended enclosure volume and type from pioneer) and put these in the back of my 2000 Toyota Avalon.... HA talk about "premium audio system" Who needs one when you get aftermarket bass like this for this price. All my other setups I've used ported boxes because they are usually louder by about 3 db. These subs are actually a good bit louder in a sealed box than my older ones were in a ported box. These go LOW for 10's. You can actually hear 20 hz, and in this large car, that's an accomplishment. Here's the downside, you don't get too much high bass but it's acceptable. I tried the Pioneer TS W3002D2. Just the one 12" at one point and It didn't play ANYTHING above 60 hz. Now these are better than that monster sub as in you can still hear like 80 hz but don't expect much above that. All in all, it's really an awesome product and I don't know how a 10" could put out bass like these little things.
Pros: Small Enclosure Size Nice Low Bass for a 10" REALLY LOUD Looks kinda cool. Affordable
Cons: Lacking a tad in high bass.
