Review on 🎵 Goldwood Acoustic Audio AA35CB Indoor Center 3-Way Bookshelf Speaker, 400 Watts Black (3-Inch) by Angela Freed

The case is very thin plastic, there wasn't a lot of insulation inside which resulted in odd reverberation times at certain frequencies. I opened mine by removing the grille with an awl/pen and removing the 6 Phillips screws. I then covered it with 1/8 inch thick Dynamat glue which seemed to fix the problem. All in all, this is a good value speaker if you're handy and knowledgeable enough to open up the case and add some insulation. If not, choose a more expensive model/brand.
