Infinity Beta speakers worth selling?

Try to sell them locally. Maybe craigslist.

put a post for them on the "infinity beta owner's thread" here on AVS. Some people are looking for these speakers.

The Betas are pretty well regarded... are you planning on replacing them? Just keep in mind, you may not get enough out of them to justify an upgrade.

You don't happen to live in the DFW area do you?

When they go new Beta 50s go for around 400, Used 200-300. So for both I would say you could expect about 500 dollars.

I love my Beta 20s, but an upgrade could never hurt. lol.

Are you just looking for smaller form factors? Both speakers you mention are going to be a step down in some ways b/c small form factor speakers are nearly always sonically compromised.

If you like the Beta 50s sonically speaking and need the space. I suggest you consider the Beta 10s or Beta 20s. I currently own a pair of Beta 20s with Sanus stands if you wanted to do a trade with some profit. We could try to work something out.:-)
Of course the shipping part will be a bit of a pain, but it's something you can explore.

I am satisfied with the 20s, but if I could get a pair of 50s. It might be good for my old testosterone

I did a time and cost of shipping estimate for two packages similar in size and weight to a beta 50. It looks like it would cost around 200 dollars to ship them both UPS ground to where I live including insurance of up to 300 for each speaker. FYI

PM if you want to try to work something out.
You can actually take the speakers to the UPS store and they will pack it for you and ship it.

You could also list them on individually on ebay. Beta's are very popular and you would have good exposure. A beta 40 sold for 190 this weekend. I'm sure a 50 would probably get closer to 300.
