Not to sway this thread off-topic, but I've been a follower of the X-LS from years back. Bought a few pair from AV123 until they went under. The "Encore" version used a better tweeter than the original as it is more of wave-guide tweeter. Also, if you buy the "kit" from GR Resarch, you can choose to upgrade to Sonicaps, Mills resistors, etc., but that adds a little to the cost.
After selling off my Magnepan LRS and MG .7 speakers last weekend and realizing it would be a week of waiting until the MG 1.7i pair arrived, I scoured my local Facebook Marketplace. I found a pair of AV123 X-SLS (37" tower version of the LS) for $100. The cabinets were satin black and had some scrapes on them. But wait... there's more. It wasn't just that the speakers were available for $100, but that they included the Skiing Ninja crossover upgrades. I have to take out the woofer so I can see what level of the Ninjas crossover components were applied and if they did the full modification with No-Rez. Again, when I have a bit more time, I will confirm. However, the sound? Oh my! Yes, a $299 speaker from 2008 and $300 in crossover updates made for a fine sounding pair of speakers. When I got these hooked up late on Monday evening, I was taken aback. Granted, these are just my impressions in how they sounded to my ears, but call me impressed. I almost felt like getting out of the Magnepan 1.7i deal because these modified X-SLS speakers really made me smile. Much more so than the $200 I've paid in the past on used Elac B6.2 speakers and other speakers that I've owned.
Also, I upgraded my MiniDSP this week from the 2x4 HD to the DDRC-24 via a firmware purchase. Now, just waiting on the microphone to arrive this afternoon so I can proceed with running the DIRAC room correction software. Since the cabinets had some scrapes, I decided to work on refinishing them with a teak-colored finish that I'm rolling on for a bit of orange-peel surface. In the end, they should be just like new - or a little better than new.
The poor guy that was selling them for $100 indicated he just wanted to get rid of them as they didn't use them anymore. Needless to say, he wasn't aware of the Skiing Ninja crossover upgrades, etc. Also, when you go to GR Research, purchase the X-SLS components, upgraded capacitors, Mills resistors, etc. in the kit, the cost is about $475 and you then have to build the cabinets.
