I need a baffle for the current subwoofer speaker build and I was going to muck about laminating chjpboard and MDF but I'm wondering if using the 19mm flooring would work?
A half sheet at 1800 * 800mm is a good bit cheaper that the materials to do a laminated baffle.
$39- Vs $ 54 plus glue
Anybody used it and can comment?
It's an 18" driver that weighs quite a bit if that is important but I can use T-nuts rather than 1/4" screws if I have the need to.
I'll be shopping again tomorrow and need to plan my buying

Chipboard flooring is certainly high density, hard wearing, stable and moisture resistant.
I haven't used it, but I think it would be ideal for your purpose. It's available here in 18mm and 22mm thicknesses.

Should be OK.
The flooring is engineered for its purpose: low flex, strength and hardness etc. But at its cut edges the glues and bonding of the "layers" is stronger than the wood flakes that makes up the bulk. So when the edge is stressed by flexion etc the flakes disintegrate quite easily and this breakdown infiltrates over time and with moisture and further stressors. MDF is better because the particles are small.
Its difficult to estimate the speed of this breakdown in a speaker baffle but with flooring having the mid-floor sheet joints over joists it takes several dry years for "ridging" at the join to become noticeable in a high traffic area. High humidity is much faster of course.

I'll not be gluing this baffle so replacement would be relatively easy, an alternative might be some cheap Brazilian plywood but that is only 565mm wide and I'll need to batten the inside edges to take it.
I'll try it then as an cheap alternative and seal the cut edges around the driver cutout and screw/bolt holes.
