I am standing on the sliippery slope of deciding on whether to build a DIY subwoofer for my home theatre or not.
I possess the carpentry skills but not the technical ones.
I am looking at what I would need to build a subwoofer that would work well for my approx. 3200 Cu Ft enclosed theatre room. The subwoofer would be out of plain sight behind the curtain to the right of the TV in the pictures. The door way would allow me to have it so the "mouth" of the enclosure would face into the room.
The specs that I would be working with would be so I can get it into place through the 23" doorway.
I would like it to be within the following measurements if possible.
78 long x 36 high x 18 wide with the "mouth" being on the 36" side near to the end.
Am I looking at a tapped horn design here? The more I have read the more confused I seem to be getting.
The enclosure fabrication is not a problem but I am looking for some design help as well as component selection and a parts list.
My budget is around the $500-600 mark.
Is this a do-able project?
Here are some pictures of the space I am looking at using. The Velodyne sub sitting there is facing the way I would like the new sub to face but the Velodyne would be replaced of course.
Here is a picture of the doorway with the curtain drawn back. This would be closed normally.
The space behind the TV, components etc.
Another shot showing the Velodyne in the doorway facing the theatre room.
Any help or suggestions would be much appreciated.
What items would I need for this project?
High pass filtering?
I am not worried about the finish per se as it will be hidden.
I am looking to match my SVS PC12-NSD or better for sound if possible.
All suggestions are welcome.
