Goldwood TR8P Sealed Single Car Speaker Cabinet Box for 8" Dual Woofer

Before and After Pictures.Sound: It's great, if you have dual coil 8 inch subwoofer, the clarity and bass hits right.Fitting: if you have different 8 inch subwoofers, some will fit and some won't.So get your cutting tool(s) or sand paper grinder? I used a mini wood saw((i scraped more than I cut)) and used sandpaper to smooth it out.Just make sure you don't cut the hole to big, it's just enough to make the woofer fit nice & snugly. I predrilled small holes for the screws to tighten the woofers, but that's just me.Box: The sub boxes are small which is perfect doesn't take up alotta space.I love the black carpet, it matches the car black interior.Overall I'm satisfied.👍

Box was perfect and speaker fit great

This box was decently built, but it's just not really big enough to use as a subwoofer box. It may sound better vented, but it's so small that installing a vent long enough to work would be a challenge. However, it does work very well with a full range or a coaxial 2-way 8-inch speaker. Just don't expect a lot of bass.

This sub-box is junk!..

Bought this for the dual speaker connectors, sealed design and the super small size. It looks just like what is pictured. I was hoping to fit them under the rear seats of a ML55. Unfortunately, it didn't quite fit. The pair resides in well space behind the seats. The boxes are airtight but the subwoofers I purchased sounded muffled at 80 to 100 volume.The Subwoofer manufacture recommended sealed boxes. Without modification, the boxes provide much more mid bass than low freq bass I desired. Adding a 2" port hole to each box allowed me to get the sound I expecting when starting out this project. The overall sound should be even better once I install the 2" by 4" port tubes that are arriving tomorrow.
