Krakin Posted June 19, 2013 Report Share Posted June 19, 2013 Sooo if i read this right 2 18" have more cone area then my 6 10's WTF!!!! That isn't a really justified substitution for 2 18's. 6 10's will take around 3-4 cubes, but 2 18's would be around 8-10 cubes. The idea of substituting for 10's would be to fill up that 8-10 cubes with more surface area. So lets go with 18 10's, takes up roughly 9-10 cubes, that would be 900 in2 in the close to the same space that 2 18's would take up with their 500 in2. Edit: they will also take a tremendous more amount of power than 2 18's of comparable coils. So let's take the SA-8, 500w RMS x 18 = 9kw now lets try 2 x Zv3 18's. 1500w x 2 = 3kw Get the idea of smaller subs?

Hard to say which will be louder just because of all the variables. But if you do switch over make sure you have the room for 2 18's. It's all about what is practical to use. 2 18's will cost less 18 10's will have more cone area. It's mainly just how much you're willing to spend on a setup.

bass juggernaut Posted June 19, 2013 Report Share Posted June 19, 2013 my current set up is in a 1999 Tahoe, i have 6 AB XD1044's off a Crescendo BC3500 with 2 red tops under the hood and 2 SK-BT100's in the back with 2 runs of KNU OFC 1/0 front to back and a Mechman 270 up front Link to comment Share on other sites More sharing options...
bass juggernaut Posted June 19, 2013 Report Share Posted June 19, 2013 the box is 9 cube's (1.5 per) tuned to 33hz and they are wired @ 1.3ohm's but thinking about rewiring them to .33ohm's Link to comment Share on other sites More sharing options...

It would not take 18 10's to fill up 9 cubes. 8 at 1.15cubes depending on what sub would get more cone area. But I think if you waited for Sundown's new X's or Zv4's you would be very happy with them.
