Tips on unloading heavy driver from existing cab

Going from sealed to ported and I need to remove my LMS Ultras from the sealed cabinets they are in. Wondering if there are any quick tips.

I recently had to replace my SVS driver (50 lbs I think) and they sent me a real handy tool for this. I don't know what its' called but it basically screwed into the screw holes (with the screws out) and gave me 2 handles to lift the driver out.

Just 'cause you're right doesn't mean I'm wrong

linguistically and mechanically, .01 each
the OP kinda nailed a simplistic way to "giter" done
with his first word in the title,

just prepare for a soft , controlled and strategically cushioned landing . . .

worked for my UXL, also 50#,

Must be something against heavy subs and fingers? I had one of my HST's decide to use a finger for a cushion the sub is approx 60-70lbs does not feel all that good.

Troels Gravesen recommends this :

Sometimes it can be a real pain removing a driver from its cabinet, maybe due to lacquer or tight routing and the simple solution is making treads in one the mounting holes in the basket. For 8" drivers usually 6 mm threads work. For 4-5" drivers maybe 5 mm. Measure hole diameter and use the the nearest size. Insert a screw and lift the driver with a plier resting on a piece of wood. Simple as that.

I usually use one of these pick tools in one of the screw holes.

I just put a few layers of pillows down in front of the box and SLOWLY lean the box forward. Works great for the UM18, but I'm not sure I'd try it with the 5400u.

Pillow in front of woofer works best for me. Looking at putting my 15HST in a ported cabinet also.

Lag screw works well too, the coarse threads usually fit the flange thickness pretty well. The 24 I just gave up and surface mounted

I just grab the rubber surround and lift it enough to get my fingers under it. If it is stuck, flip it driver side down on a rug and let gravity do it thing. A little WD 40 can help. On my first couple of sealed subs, I let the paint dry for 2 day. Months later, I discover the driver stuck to the paint surround. For that, I used this:
