Everybody requesting Tumult update information,
It has been a long wait but hopefully the wait will be worth it. The Tumult
begins preorder on October 23rd and runs through November 8th with a
preorder price of $350. Production will be in mid November with delivery
scheduled for the last week of November.
A few items have changed from the initial specs so please note:
It is a dual 2 ohm voice coil driver which can be wired in series for a 4
ohm load for the home theater guys or parallel for a 1 ohm load for you car
guys with the robust amplifiers. VC diameter is 3" in diameter.
Stiff epoxy treated paper/Kevlar pulp cone (like on Brahma), large roll foam
surround. 8" diameter Nomex spider, solid poly dustcap (straight black -
no
logo!). Venezuelan 4 spoke basket, 48mm thick top plate, 13mm thick back
plate. Dual stack of 1" thick magnets.
Shipping weight of this driver is 55 pounds (48 pounds for driver alone).
Because of this our Canadian friends will need to order from the Canadian
dealer since UPS is too expensive for international shipments and USPS
damage rates are too high for this size of package.
Final T/S parameters:
Fs: 19 Hz
Qms: 5.5
Qes: 0.40
Vas: 113 liters
Xmax: 34mm one way
Sd: 749 cm^2
