Budget wise, the MTX would be the way to go. Good quality subs (when I was using them in the '80s anyway -- not sure of their rep now) for not a lot of cash.
Sound quality wise, I would take the Diamonds, if you can afford them.

I guarantee your 10 sounds no where remotely close to my 2 12s

As far as the speaker, I'd pick Diamond over MTX any day. But opening the field up to other options, there are a few others I'd pick first.

Plus for the money I spent and the weight and usage of the trunk I saved, ill take my lonely 10 and continue to get compliments. 
What kind of subs do you have btw? I wouldnt doubt they are better than my sub, but he is asking for one to fit in a stealthbox, putting a 12 in their is almost pointless. Getting the T-top box is a better since you can put two and get around 1cf each I believe, but the downside is the weight and cost.

Diamond Audio has a good rep of almost high end audio...
Infinity has really good specs. That's why I bought my Kappa Perfect 12's.
aluminum cone
high-roll butyl-rubber surround
massive cast-aluminum basket
dual 4-ohm voice coils
suitable for free-air use (handles up to 175 watts in free-air applications)
recommended power range 75-350 watts RMS (175 watts per coil)
peak power handling 1,400 watts
frequency response 18-200 Hz
sensitivity 96 dB
And I'd call it basically impossible to get down to 18Hz in a small sealed box.

I have 2 TC Sounds db-500s in a 3.4 cF box ported to 32 hz. I'm pretty close to doing a hair trick
By the way... my car is already slow, so I don't care about adding weight
And my box costed me about $28, so cost was not a downside for me LOL. Obviously you know a speaker low a low Fs, high Xmax, high sensitivity, and high power handling will sound better than a speaker that is exactly the opposite, the T/S parameters will tell you all you need to know there. But sometimes there are just subtle differences that can create huge improvements in your system that you wouldn't have known unless you bought the speakers and installed them
