Synthesis LM260 Speakers?

At the time (early 90's) the large model was selling around $4000.
Today, in good condition, I'd be happy with $1000.

According to the last dealer price list I have, new retail
prices were:

LM210 $1195.00/pair

LM260 $1995.00/pair

LM310 $2895.00/pair

A used pair of LM260s would be worth around $400-$600
depending on condition. They might be a little hard to sell
because they weren't very well known, but are EXCELLENT
speakers.

I'm convinced the speaker in the provided link is the LM310.
There is a "statement" version but it has separate woofer towers.
The LM260 is about the same width as my former LM210s only taller and had the sloped baffle.
I remember hearing the LM260s at a shop on Ventura Blvd in the S.F. Valley (i.e. L.A.). They were so sparkling clean and clear, compared to my Magnapan SMGs that I was shocked.
This was in the near field in a small room.
It was the LM310s that were "laid back" (brief audition in a large room).

Thanks for all the info - I was completely clueless, and that's definitely more than I would've thought to price them at. After giving it some thought, we're deciding to keep them - they still work great. If I remember correctly, this set of speakers we had may have come with a pair of smaller speakers? I might just be making it up, but I'm pretty sure that's how they were. My dad says he probably bought the speakers in the '80s, for "at least a thousand". I think our family's completely clueless when it comes to speakers.

Meilinnn..excellent choice on keeping them! They are still a great sounding speaker. I'd keep them too.
