Re: earthquake supernova 15 mkVI build

Sory wrong info. I must build 1,97cu ft (67litres) 16'16'16' cube .Must ad 312 grams ,11ounces to a slaps 15, what do you thing about it? i dont know what dimension do i have, with a amplifier inside or without. How many litres the supernova amplifier may have? i have try to calculate the dimensions what i have to a orginal supernova 18'18'20' and i thing the amplifier from supernova has 7 litres (0,247 cu ft)but i dont know the aplifier have own mini enclusure inside sub,or the amplifier is naked inside.

Re: earthquake supernova 15 mkVI build

I would say the amplifier does not have its own enclosure. The displacement of the amplifier is very small, it would not make much difference in the total internal volume of the sub. 1.97cu. ft. = 56 liters, add 11 liters for driver, SLAPS and bracing = 67 liters = 16" internal cube = 18.5" external cube.

Re: earthquake supernova 15 mkVI build

I dont know that I understand what mean bracking it is some wood in enclusere that make it firm? What do you think what thick of mdf it will be good? but please write it in milimetres.Driver has it 4,5 litres, slaps i dont know but not much becouse it is totaly flat it takes max 2 litres. 312 grams it is heavy and it is on smal bolt, it is possible that the bolt would broke the slaps.Bye.

Yes, bracing makes the cabinet firm. There is a cabinet and bracing calculator here:

The cabinet should be built of 19 mm MDF.

19mm will be good?I was searching for a 30 mm mdf but it is very hard to buy it.I was thinking to putt 3 bracking inside or one big look like wall with lots of holes. Put inside some wool?

19mm will be good. The box will not be very big, you can brace it like this:

Re: earthquake supernova 15 mkVI build

looks good but it will be hard to put this kind of crates inside becouse the speaker is big and the enclosure is small that small. If i putt a one wall with lots of holes in it.I was wonder if the orginal have it any bracking inside. This enclosure you show me is PR enclosure?

Yes, a 10" sub with 2 - 10" PR's. The cabinet size is 66 liters.
