They are a 2500 RMS rated speaker with "stock" options -- this can vary based on how it's configured. Most coil options would decrease from this; but are available for different types of response.
I've been holding the release a bit to get all of our new soft parts and frames in stock.
Also expect to see a massive array of options -- WAY more than anything we've ever offered. TONS of spider options, coils anywhere from ~81mm OD to ~88mm OD to fit mass, Le, and BL requirements (basically any coil from any 3" sub we've ever sold will work... and also the "stock" NS v.3 coil -- which is the largest OD unit by far **), optional copper pole sleeve, etc, etc.
That being said they will be fairly expensive; but I am holding off on announcing the full details on cost until I have all of OUR cost on the parts I need to make all the above work. Consumer price will directly reflect cost to manufacture compared to prior Nightshade woofers.
I would pin them on 1Q next year for full availability.
I would not expect a pre-order on them as we build them to order.
** -- I've been testing with 12-layer flat coils since the original "Monster" around 4 years ago... but I've actually changed that to an 8-layer bifilar round wire 4+4 aluminum coil (from what I was told -- the first of this type to be wound at Precision). BL and Le came out nearly identical to the 12-layers but with the round wire there should be significantly less "out-gassing" issues that can be present in flat wire coils when high heat is applied right away (bubbled formers can be a result).
