#3 MC AL CUBO HOW TO#
Number 3 = number x number x number Exampleĥ 3 = 5 x 5 x 5 = 125 How to type a cubed number The cube of a number is found by multiplying that number by itself three times. Formula – How to Calculate a Cubed Number To find the number needed to find the cube of a number, use the cubed root. To find a number to a different exponent, use our simple exponent calculaor.
Saying “10 cubed” or “10 to the exponent 3” or “10 3” is the same as saying 10 x 10 x 10 = 1,000. Saying “4 cubed” or “4 to the power of 3” or “4 3” is the same as saying 4 x 4 x 4 = 64. The “Cube” or “Exponent 3” or “Power of 3” of a number is the number multiplied by itself 3 times.
#3 MC AL CUBO DRIVERS#
So something is off, as I'm rather safe than sorry, I would exclude the STX drivers from the list.Definition – What is the cube of a number? The STX W.38.1200.8.MC, weighs 7.5 kg, (claims a large voice coil and Xmax, medium Qes) and the T/S-parameters suggest it would would be close in performance to the 15TBX100, however the 15TBX100 (also large voice coil and Xmax, medium Qes) weighs 12.3 kg.
#3 MC AL CUBO PRO#
The Kappa Pro 15LF, weighs 10 kg, has a medium Qes and Xmax, and a 3" voice coil instead of a 4" voice coil like the Black Widow has. The 1508-8 SPS BWX for example, weighs 7.7 kg but it has a high-ish Qes (less magnet needed) and small Xmax (4.7 mm again less magnet needed), so those numbers add up.
#3 MC AL CUBO DRIVER#
Only the 2 inner horn panels are different from Cubo 15 Extended, all else equal.īoth the STX W.38.1200.8.MC and W.38.800.8.MC look good on paper, except one thing, the weight of the drivers doesn't correspond to such T/S-parameters: Normally you wouldn't use the physical weight of a driver to base it's performance on, but since all these drivers have ferrite magnets and from the looks of the photo's also have aluminium baskets, you would expect better overall performance with an increasing physical weight. *** If you want to use 15 mm material use 11-ply Baltic birch, nothing less. Plans available on request.Ĭutsheet (clearly visible after download): If you're uncertain if a driver is suited, PM or mail me at This email address is being protected from spambots. ** Apart from these drivers Cubo will work with a wide variëty of 15" drivers preferably with an EBP of 100 or higher Fs (27-50 Hz), Qts (0.21 - 0.41), Vas (150 - 300 L) / (5.5 - 11.1 ft^3). Where EBP = Fs / Qts.
Si inserisce in seguito il contenuto di 1 sacco di cemento (25 kg) e. Mount the driver with the magnet inside the chamber for most output around 60 - 80 Hz or the highest possible crossover frequency.įootnotes: * 18Sound 18LW1400 in a 175 liter bass reflex tuned to 37 Hz. In pratica: si versano nel mescolatore 3 sacchi di Leca (150 litri) e 10 litri dacqua. The driver mounted with the magnet visible (the magnet in the horn) typicall gives the lowest bass response and slightly better cooling of the voice coil. Qts x Vas = 100 - 120, Cubo Extended or Standard Cubo 15 plans are also available in an Imperial version, plan available on request. The measurement below shows the gain over the stated bass reflex (see * for details). Cubo 15" is the 4 th prototype in a line of hybrids aiming at the achievements as stated above.
Utilising a non-expensive driver such as the Eminence 3015LF, Kappa 15LF and Kappa 15LF Pro** and a cut list from a single 18 mm*** sheet (244 x 122 cm) / (8' x 4') with a single angled cut, Cubo 15" realizes a cost effective, small and light weight enclosure following the KISS-principle.ĭevelopment: In 2007 the first prototype was build and tested.
Where EBP = Fs / Qts (strictly speaking it's Fs / Qes)Ĭubo 15: Cubo is a multi purpose, stand alone bass bin that will equal or out run a single 18" BR*, of similar size, from ~ 40 Hz and up in terms of sensitivity.
