jm batwing foam

First off, I have boom speakers and I like them a lot but, they don't have much bass. Well as most of us know u can't get much bass from a speaker of this type. So I added the jm batwing foam, its a noticeable difference. Is it breakthrough amazing now, no way. But definately more defined bass.

Dr vtwin was where I got it. It was around 30 bucks. Imo worth it, could I have made something else work yes, but for 30 bucks I went with their pre cut foam.

I'm not trying to jack your thread; just explaining what's going on with the foam/Dynaxorb type products. Like you, I noticed an improvement in sound, though not a "WOW" type change. I did a simple before/after test by placing my hand on the outer fairing playing the same music/same volume before installing the Dynaxorb and noticed a lot of vibration from the outer fairing. Installed the Dynaxorb, installed the outer fairing and played the same music/same volume, and noticed much less vibration. Not very scientific but there was a noticeable decrease in vibration.

Thanks, again, for your post.

I did the same Carl... and that fairing fits awefully snug. I think they are definitely effective but i agree with all of you that there is now wow factor in it. I would get it done again.
