Conclusion: I put these into an old set of home stereo tower speakers to replace some blown woofers. I have another pair of the exact same speakers with MTX Thunder woofers in them. The JBL's hit harder and clearer. The money I spent on these was well worth it to revive these old speakers for my shop!
Conclusion: I have installed these in 4425 studio speaker cabinets, they of course are not meant for that environment tons of low end , at an awesome price. They look awesome, Pushing them with a Kenwood home stereo from the early 90's running 100 w RMS and they could easily take double that.
Conclusion: Running two of these in a sealed box and they really surprised my how good they sound. I wasn't expecting much but they do get pretty loud and low. I'm giving them 500 watts rms to share so the power is perfect for their capability. For a budget sub they're perfect.

Conclusion: These JBL subs are just AWSOME! I'm using them in a vintage pair of JBL L100T's. The original woofers deteriorated over time which I purchased over 30 years ago. I had them reconed once and they deteriorated again.
Conclusion: These speakers are just simply amazing I was ultra surprised at how loud they are compared to other speakers and I would recommend these to anyone really just an amazing product they are worth way more than they are selling for.
