612s cab questions

[Colossus76]

six 16 ohm speakers wired in series-parallel is 10.66 ohms (i believe). my questions are, I have a '74 Model T and I want to run my 16 ohm Matamp 4x12 and a Sunn 612s that is 10.66 ohm. Is the 10.66 ohm load considered 16 ohms and is it safe to set my Model T on 8 ohms to run both cabs? thanks.

Combined load works out to a little over 6 ohms. You'd probably be okay at the 8 ohm setting, but I'd use 4, myself.

[Colossus76]

So setting my Model T to 4 ohms will be safer than 8?

[Colossus76]

I am just making sure before i hurt anything. Will the mismatch be safe pushing the amp at loud volumes (like on ?

In my opinion, yes. Probably not by a large margin, though.

I think i am just gonna wire up four of the speakers in the 612s. that way i will feel better.

That will create other problems. The remaining drivers will act as passive radiators, in effect making your sealed cabinet into a ported one. The frequency response will be changed, probably a lot. Still you might like it.

(ditto to what Issac said)

My bass player home-made his own 6x10 cab...we called it "the fridge" because it resembled one highly in its big, ugly, boxy looks.

Anyways, he only had money for 4 speakers, so he slapped in 2 extra 10" car subs to fill the 2 empty holes...and it sounded like dirt.  He ended up patching over the other 2 holes and dealing with the sound of an extra-large cab, then bought the other 2 drivers about a week later (somehow he came up with the money).

So yeah...his sounded like junk (we play melodic/death metal, tuned down to C), but you might like it. Give it a shot, it might sound good - I've never heard a bass played through a model T anyways except for Sunn the band...and they're not bass, they're subsonic :-p

I play bass through a T. It's a second generation unit with a few mods to make it more like the first gen. I play it through a Fender-era Sunn 215S. Sounds pretty good.
