If so do you have the proper Hpass in place? Is this your second pair of woofers or who are these from?
I know DSL uses custom drivers in their cabinet so regular ones wont work. LMSR 12's do work in the DTS 10 though if you need replacements.

Have EQ filters in place? what are they? Danley recommended ones to start with?
Which year cabinet do you own? Some earlier ones barely had enough clearance for the excursion of the surround. This can be remedied by just doubling the gasket to the face of the driver that's mounted facing inward.
It's always hard to tell by photos but many things can be at play together. If there's an air leak or one driver causes one the other will follow. The horn relies on a sealed system to work efficiently and apply full power. If not drivers will fail and yes the surround is the weakest part being foam.
Actually the LMSR isn't the only thing after sliced bread. The lab12C works as a replacement but can't handle as much wattage. DSL have replacements available that are OE; yes slightly different parameters and larger vented 3" coils. The Alpine Type R; SWR-12D4/2 also works and has more robust parts.
Interesting how much smaller the Voice Coil is 2.5" versus 4"
Only 35 days and then what...
Voice coil difference matters little depending on engineering. The Danley DTS10 driver has a 3". The alpine SWR 12 has a 2.5" but it's flat wound aluminum and forced venting handles as much as most copper wound 3" coils.
After 35 days or so I tried the alpines(borrowed), then after a couple days I put back the Danley OEM drivers. I wanted to measure but honestly lots of other projects got in the way. Sorry no data for you guys. If the alpine drivers last for reliability I'd say they are the best bang for the buck. Reason I question reliability is some mixed reviews on them. My guess is they are priced to sell and get abused so hard in car audio things happen. Some I'd chalk up to improper setups of cabinet and power expectations. Very well engineered motor venting.
