I am trying to get a subwoofer box built with these dimensions:
100 inches long 48 inches wide (depth looking at the box from an aerial view) and 10-11 inches high. At this point I have not selected a speaker. My hope is to get 2 18 inch subs in the box.
The trick is the top of the box must be flush. It has to be a smooth surface all the way across the top. Would you just build a box and mount the drivers on the inside versus the typical install type? Would you use something really thick and mill the wood so the surface will be flush (I am not very handy and have limited tools)? Will this have any adverse affect on performance?
Is there anyone that builds and ships these type of custom boxes?
If not I still need to research proper wood, screws, glue, stuffing, speaker connects, ported or sealed etc.
If it matters I am using Dynaudio Focus 380's matching center and B&K Reference amps. Room is 20ft by 12ft dedicated theater room with 8ft ceiling
Thanks in advance for any advice.
