Need help with box size for HST-18 Nearfield sub

I need help picking out a box size. I want sealed not ported. I will be having 4 enclosures built. Each one firing into the back of a seat. I read where auburn008 made his 4.5 cu ft. Can someone who has that program please help out. Thanks in advance.

Hey Kutlow,

What are you size restrictions for L,W,H?

Also, what will you be using for power? The larger the box the more efficient the low end is meaning you could possibly not need as much power to drive them to x-max...

I will either use a :Crest Pro 9200 which has 2200 watts @4ohm or a
Crest Pro 8200 which has 1450 watts @ 4 ohm.


should I use the 9200?? I don't want a huge box but sealed

I'll try and model something tomorrow, but here's a thread modeling the HST for you to look at tonight that shows you what you would get with the 9200. There really isn't a huge difference in size for what you would be able to fit behind your chairs. You could go as small as 3 cubes if you need to, but I would go with 3.5-4 cubes net from what I have read looking through all the threads I could find on AVS regarding the HST vs Othersubs. The 1-2db difference here and there is not audible. Besides, you are going to get the crap beat out of you nearfield with these.



I'm thinking a 22" cube (double baffle plus a recess) would be nice if it fits. It gives you around 4 cube net and plenty of room around the driver for a 3/4" roundover.
