123w/150w
i don't know other than the wattage i couldn't tell u. With the information u gave i can't tell u much. If you had the type of infinity sub each one was and the model that it is we could help u more.
Are you reffering to the reference series versus the Kappa series or the Perfect series? I have had both the Kappas and the Perfects and can tell you from personal experience of myself and several others I have known that we all experienced a problem with any of those subs that they make a nasty clipping sound under heavy power loads.(Over 150watts.) I really like them all and they all sound pretty good in a small sealed enclosure with small power but they don't like the heavy juice. I don't reccomend them on that reason alone. I find that Diamond Audio makes a killer sub for less money that handles more power and sounds just as good!! Try to find some of there stuff if you can!!! They are a small company but there speakers are amazing!!! I would reccomend a D3 series woofer. If you want to spend a little more there D6 stuff is unbreakable!!! I have personnaly hit there D6's with over700 watts continuous with no problem!!!
Well I don't have any experience with those but I would assume that they sound okay. Like I said though, my personal experience with INfinity is that they sound good at lower volume levels, but can't handle much power. If you hit them with there nominal power input they should do you pretty well
