He said extreme bass. The Wharfdale SW150 is 10", 250W amplifier. That'll only do so much. When someone asks for extreme bass, then typically looking at larger subs, 15" or so

"Extreme Bass" is still definitely subjective.
For me, 500w is nowhere near extreme bass.
Try listening to car setups pushing 150db+ with 10,000w+. You can't see straight and breathing is a struggle. You really have to concentrate.
Same way if you're used to apple earbuds, the "bassy" iems will seem like extreme bass to some.
Not trying to sound salty, just saying you can get some decent bass within his budget.
