I just bought 2 HX2 RFD2112 for $129 each at sounddomain.com. They have those 10s for $109.95 so that is a good price.

Thats a good price. If they were 15s i would try to get them. DO you know of any good deals on any 15s with the same quality as that series?

It'* a Kove Armageddon Z series without the Kove nameplate. I've got the 12".
It'* very angry with lotsa power.
RF'* are a food group to these beasties.

Depends on your box. Do you already have one or are you looking to buy or make one?
As far as the 15, I honestly don't know. I do know the laws of physics tend to cause overhang on the bigger subs. Hence I got the 12". I've got a sealed ~1cu.ft. box. It'* very articulate and can dig deeper than I will allow it electronically. Can't hurt to try one. That'* a wicked price for that kind of performance. I think they have a 30 day no questions policy as well. Don't quote me on that. Check their site. I do remember seeing it though.

I will be making a custom box. I havent heard about overhang up until now, but wouldnt a good suspension greatly reduce this effect if not eliminate it if it were in the right sized box? In your opinion would it sound better to go with 2 12s with a low Fs? What about resonant engineering'* HC series they are the subs that i was originally considering. Have you heard anything good about them

I would go with the 2 - 12'* in individual sealed boxes. You will get tighter & better sounding bass than you would with the 15.

Never heard of Resonant Engineering. Took a quick peek online, they look decent.
I'm just wondering if your looking for SPL, SQ, or a blend. Probably a blend.
15'* aren't going to have that "tight" sound. Physics don't allow it. The mass of the cone alone is enough, yet folks are looking for stupid power handling. That USUALLY means a big coil with lotsa copper, aluminum, whatever they're using for the conductor on the coil (I would not want a speaker designers job these days). Gotta dissipate that heat.
The suspension compliance can help alot at the loss of efficiency. Enter the motor.
I haven't seen the Dumax on these subs , so I dunno about the BL thru the gap.
I do know that listening to this ONE 12" is very gratifying. I personally wouldn't go with anything other than sealed if you are looking for SQ. That 15" in a ported or bandpass could probably do structural damage to your car with enough power
I'd recommend one 12" for SQ. Two if you're looking for stupid output with a bit of SQ.
Obviously these are my opinions.
Whatever you decide, let me know, maybe I could give you a bit of help designing the box.
I've got some decent software for modeling such things.

Me again.
Lower Fs in a car is redundant. I've measured the bass lift (or whatever you wanna call it) in my 2000 SSEI. It'* ~10db/octave starting at ~90hz.
Check out this link to learn a bit more.
