I'm about to reconfigure my music area, and I just had a few questions about whether I would nee to add any acoustic treatment behind my speakers and if so, an alternative to something like rockwool that could be used.
Essentially because of the space, there will be about 7-7.5" of space from the back of the speaker to the wall. Speakers are Neat Motive 3s, rear ported. Would it be worth adding something behind or would that just add to the extra boominess that comes with having a speaker in close proximity to the wall since there'd be even less of a gap between the speaker/wall?
If it's worth doing, the max size of the panels I can make are 14" x 18", which is why I'd be looking for something other than that rockwool acoustic insulation because I just don't need hordes of the dampening material. I've come across this: https://www.amazon.ca/BXI-Sound-Abso.../dp/B07XQYRZ5X
but am not sure how effective it is.
I don't need any instructional videos on how to build these things - I'm an artist (printmaker/painter), so I know how to build frames, and stretch material properly - I only need an alternative option for the filler since everyone in the videos I've looked at to see what people use is most often that rockwool material.
I do have bungs I can use to plug up the port, so that could maybe even be a third option?
