I’ve been refered to this forum for my question.
I’ll try to make it short and as precise as I can.
and please don't be too harsh, its my first subwoofer design. so please, haha be kind! I'm still learning.
- I’m building a subwoofer coffee table.
I’ve discuss many design possibilities with my wife. She agreed on a table.
The design discussion included things like:
- - under the couch: cant really do it because couch is only 4in off the ground.
- - under the tv cabinet: she didn’t like it because the floating effect of the cabinet.
- - on each side of cabinet: she didn’t like it either.
- - behind the couch: not enough space to put a subwoofer, couch is already 6in forward to accommodate a table, and we could not forward it anymore.
- I already have (2) Dayton audio UM-15 to go
- I have 2 behringer inuke6000dsp to power the 2 UM-15
- pannels are already cut, but I’m willing to make (minor) modification to the box
- pannels are Baltic birch plywood. Bracing are mdf. And grille for design #1 is a mix of mdf and BB plywood.
- I don’t want to have visible hardware once the grille is removed.
- I’m working with ~ 135 liter of internal volume. As design #1 (facing outward) measurement of the table are : 16.5x16.5x40in outside. Inside measurement would be 15x15x37in.
- living room is ~ 10x 10, but is open on kitchen and hallway, which total gives a 18x30ft room.
- subwoofer will sit at ~ 16in from the wall on one side, and ~ 25ft of the next parallel wall. But will be in the “centre of the living room” (replacing the round coffee table in the picture)
Subwoofer use: tv/movie, video game and music.
So, I design the first one. And when I was brainstorming on ways to protect the subwoofer from our 2yo (1yo at that time) I came up with design #2 (bottom one). At that time, on another forum, people could give me the informations needed to confirm if #2 was a good idea and if it would work well. So I “scrapped” it.
When I started building the subwoofer again, I came up to the part where I need to think of how I’ll be making the grille.
In design #1, there are 2 baffle. Driver sits and screwed on baffle 1 and I have a second one over. Grille is made of (2) thickness of mdf Than the 1-1/4 slats.
So I started to think that this grille is going to be very heavy, and will need a sh*t ton of magnet to hold it securely in place.
That’s when I started second guessing my design.
So at this point, I think I have 3 option.
1- stays with design #1 and don’t make grile cause the driver is sturdy enough and my 2yo is kinda old enough to understand not to play with the woofer.
2- stays with design #1, and change the grille design for something Lighter ( I came up with a “acrylic folded box design” with a laser cut pattern
3- goes with design #2 and make a “slot” subwoofer.
My question is:
Would the slot subwoofer design would be a nice sounding subwoofer?!
Hopefully I provided enough information.
(Also, I added a picture of my CSS Audio Criton build as LCR)
Picture 4: grille
Picture 5: bracing
Picture 6-7 : LCR with laser cut grille, 3d printed grille stand off, and corian baffle (backed with 3/4 birch ply)
Edit: this is what I was talking about when saying folded acrylic sheet.
Open on 2 sides, top and bottom are used with magnet to old on the box. Different pattern than the one showcased because my computer had a hard time to render the one I wanted, and honestly, my skill in fusion are not on point, yet.
