Yes, both Mini-DSP and PE ship here. For sure PE, but I believe that you can get shipping quoted directly on both web sites.
I was curious on shipping costs so I checked. The solstice are currently out of stock. I checked the shipping costs for a pair of the Tri-Trix tower kits. This kit, much like the solstice kit, includes all pre-cut CNC panels. So, you would not have to spin a saw @ all. Just clamps and glue. Anyhow, the quoted shipping cost to NZ was $150USD. The penalty in buying pre-assembled tower speakers here is going to be much more than that!
On those Rythmic subs. Great servo control system from what I have heard. I used a 12" Velodyne servo system for a while and it had surprising output for it's size. Here is an alternative.....even if you are not comfortable with a saw:
2 x 15" Ultimax kits (complete with CNC cut panels) and a MiniDSP 2x4 shipped to NZ $1075 USD or $1641 NZD (@ the moment)
1 x Behringer NX3000 (220v) sourced here in NZ $600NZD
Dual sealed 15" subs, full and independent dsp, Just under 1kwatt rms apiece, nothing but glue/clamps/paint totaling about $2241 NZD. So, how much were the Rythmic subs going to run you?
I'll get you guys on the DIY audio train eventually 😎
