Developing a 600-watt RMS 8" woofer with fully custom frame, cone, surround, spider, etc...

Frame supports ~35mm one-way linear travel and the soft parts support that as well. Design is motor limited to 19mm linear one-way and 30mm before leaving the gap -- so it will be VERY difficult to reach mechanical limitations even by accident on SPL burps.

The soft parts, frame, and so forth are VERY over-engineered to support any future motor designs I may desire to produce... meaning you may see a true high linear stroke "SQ" style design with these parts later on -- but first we are staying true to Sundown heritage and designing a super rugged "daily" woofer that will produce excellent SPL numbers as well.

The frame by itself :

The frame with cone, dust cap, and surround :

The frame with cone, dust cap, surround, AND spider :

Surround will be stitched to cone for further resistance to damage in extreme applications.

Yes -- we will be eventually making this style driver in bigger sizes... the 8" is coming first as I really felt the NEED for better platforms as I've been severely limited with existing frames in this size.

ohjay - We're definitely not calorie counters, 'cause we can't count that high.
onebadmonte: Did you feel it?
denim: Yes, both monitors were shaking bad. I work at a mid-size engineering firm. Funny story, the structural department all stood up and none of us said a word and we all hustled out of the building, the entire electrical, process, mechanical and piping departments were staring at us.
Julian: "Our Structural engineering senses are tingling, quick let the weaker electrical, process, mechanical and piping departments die!"

I made a new thread specifically for the X-8 platform as the other thread was mainly for the frame and also discussed the NEO-8 (the NEO-8 platform will be worked on further once the X-8 is done and in production).

Looks like this will be a very well built sturdy driver. I am excited about the specifications based on this design but a larger size, such as a 15".

Haha - okay :)

Lots of things have changed since 2007 -- we are much more capable of bringing new products out faster than back then.

Artificial Intelligence is no match for Natural Stupidity.

We must reject the idea that every time a law's broken, society is guilty rather than the lawbreaker. It is time to restore the American precept that each individual is accountable for his actions.
