Connecting speaker switch to sub?

I have a vintage amp (Nikko TRM 750) currently connected via the A speaker outputs to a Polk PSW10 subwoofer, and the sub is connected to a pair of Dayton Audio B652 Air speakers suspended from the wall. It is a great everyday set-up that does not take up a lot of space in our living room and is pleasing for low-mid level volumes. But it does not have the presence I am looking for when we are entertaining.

So I also am considering getting some larger speakers, a pair of DCM TimeFrame TF250s, running off the same subwoofer so I have plenty of base. (I would run this setup separately from the B652 Airs and sub.)

It seems to me I could attach an A/B speaker switch to the sub outputs, then the run the A switch outputs to my B652 Airs and the B outputs to the TF250s. The B652 Airs are 6 ohm and the TF250s are 8 ohm, so I am looking at speaker switches that have volume control for the A and B outputs, to get the best balance.

The only flaw in this scheme that I can think of is that I the crossover point I currently am using for the subwoofer may not be the best setting when powering the TF250s. But I don't mind making the manual adjustment since it is not something I would be doing every day.

Does this sound logical? Am I missing something important that I have not considered? Thanks

That sounds like it would work fine. I think the volume control on the sub is all you need, not the separate volume controls on the speakers. Keep it simple. Manually dial the sub to the speakers, not the other way around.

Great point, that makes sense now that I noodle it, thanks
