| i have a mos-valve amp that says 4 ohm min. can i use a JBL 16 ohm speaker. what will or won't i get using that set-up. If it won't work, is there anything i can use to lower the ohms other than using 2 16 ohms to bring it down to 8 ohms. thank you BOB |

Bob,
You will not hurt anything using the 16 ohm speaker, but the power out will be reduced considerably. Depending on when and where you use it, it might not matter. (Bedroom-not a problem, stage-big problem)
Using a 4 ohm speaker will basically quadruple the power output, although that doesn't mean it will be 4 times louder, but there will be a big difference.
I notice a big difference in my MosValve when I changed from 8 ohms to 4 ohms.
Good luck!

It's probably best to combine the 16 ohm
speaker with another (preferrably 8 ohm).
That will get you closer to the 4 ohm load.

| Seems combining speakers of different impedances would result in unequal dissipation of power? That is, one would be louder than the other? |

It would be, but only slightly. Probably not really noticeable. The closer you can get
to the 4 ohm, the more efficient the power amp
will be with slightly more volume (but not
dramatically more). Ideally two 8 ohm speakers
would be best of course. |
