Hi all, I'm wanting to replace the speakers in my old Harley Benton bass cabs. Used these for home use but wanting to improve them and take them to gigs. I have a 2x10 and 1x15 cab. Looking to replace them with Eminence speakers but there's that many on the market,I'm unsure which ones. Any recommendations and do i need to replace the tweeters too or will they be ok. Need to be 8ohms each and in using a Line6 HD750 amp. Can anyone help?
