I just had some fun with a friend.
He's demo'ing some used Spendor S9 speakers. These are pretty much full range three way speakers that may have pioneered the look of Spendor towers now. They are about ten years old, but in very good shape. They're a bit wider than my A9s because they have a single 8" driver for the LF and the rear firing port is wood where later refining made that port a composite with spikes on it.\
The S9 speakers have pretty good photos in this expired ad I stumbled across:

They're the descendant of the FL9, but may have created the form-factor that Spendor is now using for towers.
Being a former soundman for bands, I do tech because I can but my first love is optimizing systems in rooms. My friend's room is probably about 14' x 25' if you consider the partially partitioned front entryway part of the room.
Well, over three quick listening and repositioning sessions, I got the system to go from performing fairly well to properly scaled and fabulous, with a true stereo image hanging well above the speakers, as well as forward and behind the speakers. The spikes aren't on yet, we've tipped the speakers back with some marble stone samples in the house as examples for a kitchen renovation.
Also, I brought over one of my tube integrated amps, the HK hot rod as shown in this thread:

Internet rumor mongering says these speakers like big power SS amps, but that's not my experience in this environment. We took out the big power SS amp and put this tube amp in and it really lit up the speakers. Then there was a little bit of pushing them closer to the back wall for proper bass loading.
The final piece that really dialed them in was introducing a powered subwoofer for that bottom bottom only. Even though this was a cheap one and I couldn't dial it in exactly the way I like it because the lowest crossover frequency was too high, it really gave the big instruments their proper weight in the mix while still providing the best of the full range speaker experience. Within those parameters and with that subwoofer, I still think it's a touch too low in amplitude, but non-directionality in the subwoofer is preserved. At a higher amplitude, you might be able to localize it.
These speakers are not new, but the are the proper scale for the room and work well in that environment. Plus, I had a blast being given permission to play and getting good results.
