What about the other way around?

Hey everyone,

I understand that an SS amp in general will double (or some percentage of doubling) in output when going from 8 to 4 ohms.
What about the other way around?

Assuming the reverse is true that wattage output will be halved as resistance doubles, would a pair of 15 ohm Rogers LS3/5As (82.5dB/W/M) be too much of a load for a 50 wpc Forte 1A?
With ~25 wpc, should I be concerned about clipping?

This is for a possible bedroom (12' x 16') setup.  Semi near field (about 6' or 7' away) classical, jazz and some light rock listening at low to moderate volumes.
 
Thanks!

Thanks for the responses!

Think I will go ahead with the bedroom system.

I also have a 60 wpc Jolida SJ502A tube integrated.  
Doesn't look like impedance affects output for tube amps like with SS.
But it also doesn't hurt to ask.

There are 4 and 8 ohm posts on the back.  Would the higher impedance speakers be more ''efficient'' on the 4 ohm posts?

How would the different impedance whether using different posts or different speaker loads affect the output for tube amps?
