Hey Luke, long time no hear! Great results to report on your 'lines.

First I put them into my lovely Peerless 830500 85L subwoofer box with two passive radiators. Now I have lovely well controlled and extended bass that is less boxy, near impossible to localise where it is coming from and I believe greater output than I had (although admittedly hard to measure subjectively).

But the best news yet. Are you sitting down? These 'lines make brilliant diffusive panels for your listening room.

I previously had some acoustic foam tiles behind my couch to cancel the reflections off the back wall only a few inches from my head. I turned the panel around and stapled some basslines to the other side for comparison. I had a friend insert, remove and rotate the panel to hear the differences while playing some familiar tracks.

The basslines panel was a considerable improvement - more lively, vibrant and engaging to listen to. I highly recommend basslines for your audio projects. Its ease of application and low cost make a sure winner, whether it be for subwoofer or acoustic diffuser use.
