people may hug ur nuts jacob but there is no denying why....
I'm no expert but these baskets seems like a quite an improvement in terms of strength and overall design. Did you get a patent for that design, when
if at any time, will these frames be part of a new Sundown 8", 10", 12" subwoofer line? Looks sturdy, do you mind if I ask if there is a difference in the
material used to cast these new frames that you used in the former, and what material was used in previous lines to now? My guess is some sort of die
cast metal composite.
James 1:2-5 2 Count it all joy when you fall into various trials, 3 knowing that the testing of your faith produces patience. 4 But let patience
have its perfect work, that you may be perfect and complete, lacking nothing. 5 If any of you lacks wisdom, let him ask of God, who gives to all
liberally and without reproach, and it will be given to him.
Almost all speaker frames that are not stamped steel are cast aluminum -- as are these. You occasionally see polymer frames or other odd-balls but usually just steel or cast aluminum =)
These 10/12/15 frames will appear on all of our lines ABOVE the SA series; likely starting 1Q next year as it will take some time to get them in stock along with the soft parts -- unless a driver has a ton of excursion, power handling capacity, and/or serious heft to it then it's not worth it to use these due to the cost; so we'll reserve it for 3" and 4" coil drivers. As the original post indicates these have ALOT of aluminum in them -- basket production piece cost is almost directly proportional to mass so naturally :
10" 12-spoke : 1.7 lbs
10" Sundown : 4 lbs (2.35x material)
12" 12-spoke : 2.3 lbs
12" Sundown : 5 lbs (2.17x material)
15" 12-spoke : 3.4 lbs
15" Sundown : 7.9 lbs (2.32x material)
I do have some ideas in the works for a "light duty" tooled frame for the SA and SD-2 lines but these were my first priority as I feel that frames are more of a limit for me on beefier drivers -- the 4 and 12-spoke work well for 1kw and less units... none-the-less I do plan to bring my own frames out for smaller drivers later on.
why the increase in depth?
You also need adequate depth from the spider to the surround to ensure lateral coil stability (no ticking) and also to have enough cone depth so the cone doesn't rub against the spider at high levels of travel -- both 4 and 12-spoke frames are quite problematic in 10" size when using the 8" landing... and when using the lower landings you are limited by a smaller spider and less rearward clearance.
So the summary is actually simple -- for the speaker to move more we need a taller basket
Got some photos of the 10" cone/surround -- the first one to be completed. Stay tuned as the other sizes are completed.
Ill take a pair and baskets to match

Trade with cf2004
Holy **** that cone and surround looks crazzy
Whoa! Beefy. I can't wait to see a full mockup!
so, i'll ask again. when/can we buy individual parts? i surely could use a 12" basket for the phx2 i'm about to rebuild, and a surround for an alphasonic i'm going to upgrade. can't wait to see one of these in action.
*IF I have forgotten to exchange feedback, please let me know*
i buy broken amps....
No, i will not "gift" paypal. please do not even make it awkward by asking. if the fees are an issue, I am usually inclined to add them. unless you have discount elsewhere, shipping is through usps flat rate, through usps parcel post, or through the roof..... i am in alaska. thanks
Good God those are hot. ETA on 15's?
New ride... new system...

New frames and parts look beefy! Could you do a quick mock up on the 10" with a beefy motor? (Just for us to drool/wank to)
