I was given a Yorkville Bassmaster 100 when I bought my MIK Squier P bass because the amp's speaker farts pretty bad at higher volumes when the bass setting is at about 4 or higher. Anyway, anyone have any advice on a cheap replacement speaker? A local Kijiji ad has a "used, excellent condition" Peavy Scorpion for $64. I always thought Scorpions were guitar speakers (enter fond memories of Peavy Bandit amp here), but I've read ONE review that said this one makes a good bass speaker; it's a Scorpion SP-15825. Will it fit (the original "farting" speaker and Scorpion are both 15" in diameter)? Is it overkill for a 100W amp? I must admit I get confused about ohms, the different types of wattage references, etc. TIA!
