Alright, i got a OLD 1x15 peavey cab, no numbers that i can find, and it's got a weird 15' in it, like, it's got a somethin in the speaker where the,, what is it,, dust thingy? the thing the cone is wraped around (Sorry, brain not working tonight.) Is like, a thing of metal, i havent taken the screen off yet, so i'm not sure. i asked the guy what it would tak as far as power. he said "150 rms"... ok, thats what i would be feeding it, and i have nothing else to go on but his word, because i have no info on the cab. but ok. I play thry it,, sounds alright. I get it home, plug it up, and it's FARTY! not, HONK, just purttttt.. I mean, it's not growling, it's doing something else. but it doesnt sound like I'm overpowering it. It's tall, has a front port, and just a hole in the back , a 1/4 speaker output. and nothing else. oh, it has a handle on top, if thats worth anything. but could it be the 15' itself? could i replace it? It is NOT a "tight" 15. AT ALL, so, what can i do to make it tighter?
