Well, I have to say this. Its all going to be personal preference.
You drive a Ford, get stuck and the guy w/ a dodge pulls you out. You get your dodge stuck, the chevy pulls you out. Your chevy is stuck, the ford pulls you out...(mean while the guy w/ the toyota is sitting by the mudhole drinkin beer, rims and paint clean).
Hell, I have ran the old Adire Brahma MKII subs...back then 'people' were *****ing about how XBL^2 didn't have nice high-bass output, WTF??? really??? My Brahma sounded great. Then less than year later they all spammed the web about how great the Mag was for SQ and highend bass. Then WTF do you know...a year of 2 later...the Mag is using XBL^2. WOW....LOL at all the internet bandwagon cawk suckers.
To each their own. If you like the tight punchy sound of a DD2500...have fun. Play the hell out of it.
If you like your muddy, sloppy Kicker L7...blow it and buy another one...lol
But hey, get in my Avalanche w/ DD3515's and tell me they sound 'hollow'...lol
