I have used Avatar bass cabs or years. I own two 9f their B210 Delta cabs. I bought the first one in 2006 and the second cab in 2009. They have worked great for all these years and have been gigged and practiced on consistently. Their products are US made and built to last. They use real 13 ply US plywood and high quality US built speaker componemts. They offer lots of Tolex color options, grill fabric colors or standard metal grills as well as Rhino Coating options for the cab. No other manufacture comes close in the price range.
Customer service is excellent too. My first cabinet was damaged in shipping. When it arrived I notified Avatar and 48 hrs later there was a new cabinet at my door. That was before the call tag was issued by Avatar to pick up the damaged cabinet.
The Avatar products are an incredible value. They are conventional in design so nothing earth shattering in the design and there are a few compromises in the design to keep the cost down but over all they are as good or better then any of mass produced cabs from insert name here _____
for a lot less money and they are not made in slave labor country.
