hey guys i just got a pyramid tw47 from a friend for free, and i am wondering if anyone can help me get this thing working.

i have an amp pushing about 200 watts to it but its hpf sucks with the freq set to a whopping 180 hz..............lol
...well the amp in general sucks, but i am wondering what i need to get it sounding good.

im new to the (powering a tweeter with an amp)
and crossover deal.

so should i buy an amp that works with 2khz -250khz?

or a crossover?

i honestly have no damn clue. please help
