OK so I'm building my "Frankenrig" for practice and fun. I'm trying to keep it cheap by using stuff I already have. I have two combos I'm going to run together. A Peavy TNT 115 which I discovered has the cruddy Blue Marvel speaker and a Peavy Basic 112 which sounds real good but it was stored improperly and a dog pissed all over the paper of the speaker...
So I want to replace them both. I would like to just order some online and put them in myself. I need a 12" and a 15".
Question 1: My Basic 112 has an 8 ohm speaker originally and is rated 50W at 8 ohms. Can I replace it with a 4 ohm speaker? The basic 112 is rated 75W at 4 ohms.
I was thinking of getting the Eminence Pro Audio Lab12C which is a 4 ohm 12" speaker but it is rated a 500W so will it be too much for that little amp to properly drive?
Another option for it would be the Eminence Delta Pro 12A which is 8 ohms and rated at 400W.
Am I even in the ballpark with these choices or am I in over my head?
Question 2: My TNT 115 has the cruddy Blue Marvel speaker. I have heard bad stuff about them and if I could still get one I would go get a Black Widow and put in it but I heard they are not what they were so instead I am looking at Eminence Delta Pro-15A which is 8 ohms and rated at 400W.
Good choices? Got better ones?
