I'm late to the party, but there are some interesting ideas in this thread. Some remind me of a couple ideas that I recently had.
One idea was an NX-Static. The X-Static speaker with a Neo tweeter. Get that Neo goodness into a less expensive speaker that has decent enough bottom end to not _require_ a sub.
The other involves my favorite GR speaker that I have ever heard - the LGK Wedgie. Of course, I have only heard a few GR speakers - the Wedgie, NX-MTM (or MTM-Otica or whatever you want to call it) and NX-treme. All systems that I have heard included those wonderful H-frame subs. Several thoughts here... One is that I hope that the Wedgie is resurrected using the LGK 2.0 drivers. Said Wedgie still requires lots of bass help as it only goes down to about 200Hz.
My first thought was a speaker like the NX-Otica, but using the LGK drivers for the mids. Something like a Wedgie on top of an NX-Otica bass section. This would allow the sub to be just a sub and placed separately from the main speakers - wherever a sub does best instead of the compromise required using the H-Frame as a monolithic bass section under a Wedgie.
The other thought harkens back to the X-Static and is similar to the NX-Static that I mentioned above. This idea is to use the bass section of the X-Static design with an LGK Wedgie on top. This could be 2 piece or monolithic - either way seems reasonable to me. The idea is to get decent but inexpensive bass support for the Wedgie.
These ideas are driven by my love for the NX sound and the Wedgie in particular, and my extremely limited budget. Seriously, I significantly prefer the sound of the Wedgie to the MTM-Otica. A pair of Wedgies would be a year worth of budget, or NX-Oticas would be a multi-year budgetary project. I would love to build a pair of double H-frames but that alone would be yet another multi-year budgetary project. Retirement is coming soon and I would like to be able to enjoy these projects for some time. Barring winning the lottery, that prospect doesn't look great.
Sorry if this is a bit of a rant, I don't want to whine... My challenge these days is having champagne tastes on a root-beer budget. I have indeed collected some fine equipment over the years, so electronics is less of an issue but I am feeling the desire for a speaker upgrade. The Acoustat 1+1s have ceased working, the ML CLS need total rebuild and while my Maggie MMGs are nice, I would like a bit better for the main system.
Still... one of the crazy ideas above might make NX sound almost affordable.
