Thanks for reaching out.
You are able to connect either the 251 or the 151 speakers to the SA-5 Amplifier, yes.
Let me know if you have any other questions.

I have the same situation. How can we connect them together with SA5 amplifier ? I mean same time. Could we do as below:
_ 1 pairs of 251 connect to L and R channel on output A
_ 1 pairs of 151 connect to L and R channel on output B
Is there any harmful with my SA5 or these speakers ?
Thanks for posting and welcome to the community.
This isn't something that you will be able to do as the 151 SE speakers are not compatible in parallel in a 2 pair set up. If you have two sets of 251's this would be fine!
I hope this helps and if you have any further questions please don't hesitate to ask.
Thanks for your reply. However, as I know the power of 251 is 100w/channel ( 6ohm) , 151 is just 50w/channel (6ohm) . So why cannot connect parallel with 151 pairs ? I need the very detail answer from your team.
And BTW, how about FS51 with the parallel connection to SA5 ?
Thanks for reaching back out to us today.
This is because there are Variations in resistance due to certain frequencies and each speaker pair connected to the amplifier requires power handling of 100 W and a minimum nominal impedance of 8 ohms. If using two pairs of speakers, each speaker must be 8-ohm minimum.
Yes you can use FS51 with the SA-5 and the 251's!
I hope this helps!
Thanks for getting back to us, you are correct that the 151 cannot connect with another set of speakers using the SA-5 Amplifier. Also, the following speakers cannot be connected in parallel with another set of speakers using the SA-5 Amp.
I hope this helps.
