Double trouble construction question.
« on: 2 Jun 2024, 08:30 pm »
I'm close to pulling the trigger on a pair of the Double Trouble subs, but have a question about how they are built first. Are the top and bottom pieces structurally necessary? Or can I omit them? I'm talking about the pieces that stick out past the main body of the cabinet. I know it's a small amount but I have fairly limited floor space and that extra bit of width seems very limiting. (considering I need to find space for the amplifier boxes as well). In the cabinet plans pdf on the GR website that part is describe as a decorative base, so I assume it's not strictly necessary, but I'd like to know for sure before diving in.

They are structurally necessary and must be there. However, the top and bottom pieces don’t need to extend past the sides. They can be flush with the outside of the side pieces.

If you aren't already aware, have a look at the modular version at the link below for pics of end caps.  I wasn't aware of these but they've existed for some time.  They can be separate, or stacked / bolted together.  The base on this is much bigger, because they are going to be tall.  See the top cap, which is thicker and flush all the way around?  I'm pretty sure you could just have another of those caps for the bottom (just like the one on top).  I think he can make it as a non-modular, double unit as well and flush all around with no overhang for the top or bottom caps.  Jay "Captainhemo" makes these and is very helpful about helping to figure out the exact recipe.  You could get the flatpack from him exactly the way you want them, and the parts from GR.

How limited are you?   These are open-baffle, and that baffle needs to be at least three feet from the back wall.

Okay thanks. That's unfortunate. I'll have to figure something out then.

Depth is fine. I'm more concerned with the width of the room.

Thanks for the info. Do you know if the price is comparable to the official flat pack?  Is Captainhemo their AC username? I couldn't seem to them.

Width should be no problem in my experience.  Mine are right up next to the walls, but pulled a few feet forward (with bass traps behind them).

Your room is a great deal wider.  Mines only 12 foot and change.

My point was you could put them right up against the side walls, so room width shouldn't matter.  Just pull them forward away from the front wall a bit.   :)

And with them outside the mains like that . You may want to try angling them towards the main listening area instead of straight ahead and see if you notice anything... The subs are actually directional.
