OB Update ...

Swapped out my Audio Mirror 45-Watt SETs for a 2A3-based Whammerdyne DGA-1 Stereo Amp.

... I've stopped looking for gear. I'm confident this is my end game system. Superb.

Impressive set, how it sounds ?

Based on my experience so far the F-15 hype is true. These are incredible wide band speakers with excellent bass even without LF assist. They play high enough that you don't feel like you're missing anything on the top end. Just the ticket for anyone wanting crossover-less HE single drivers on an easy to build flat baffle.

OK; an ESL isn't what everyone had in mind but... does my speaker count as an OB?

Maybe my best open baffles so far: Lowther, F-15, and Eminence Alpha

I noticed many of the youtube videos are featuring the Lii Audio Fast 8 wired in parallel with the F-15. I didn't think too much of the idea until I tried it with the Lowther DX3 and F-15. Now I'm a believer. No crossovers or filters other than the frequency control on the plate amp which powers the Alpha bass woofers. The DA-9 amp I'm now using to drive the Lowthers and F-15s does have some useful EQ settings. I'm lost for words to explain how good this set up sounds.

As nice as the SMSL DA-9 amp sounded driving the DX3's and F-15's things improved when I subbed in the 2a3 Bottlehead mono blocks. Had to rewire the OB's from 4 ohm to 16 ohm as I was afraid I might stress the Bottleheads which are wired for 8 ohm speakers.

I started out by building solid mahogany baffle boards (28" x 28" x 1.8") for the Lii-Song F15, with flush grill rings. Also, floor mahogany stands with adjustable tilt.

The imaging was suboptimal with the floor stands, so I tried raising the speakers to built-in cabinet height - imaging greatly improved, but now too high for my taste.

After several more experiments, I built a set of ironwood (ipe') rolling stands to raise the floor stands to my ideal height and make trying different speaker positions easy. Now it all sounds great IMO. I do use a subwoofer occasionally to augment the bottom octave, but it's rarely needed I've found.
