I have a prototype SAE-100.4 on the way with my 1200D shipment... here are a few pictures of it to share : It features a new double sided board design like the SAE-1200D v.2 does. Crossovers are very basic as it is an SAE model and it is also made in China alongside the SAE-1200D. This will NOT replace any SAX multi-channel models... it is simply a part of our lower cost SAE line. There is NO ETA YET... price is also pending.
