You're absolutely right!!! I do have the potential to make something better than the commercial product,at the same time, risking to do a worse job too. But I do make sure that cabinets are done right and that I ask as much advice from the experienced builders such as yourself. The cabinet I would like to make need to be versatile, where single cabinets are great for small to medium venues, and sevral cabinets stacked together can be used for larger venues. I decided on either a 3-way direct radiating system with a 15" for LF, 10" for Mf, and an eminence PSD2002 compression driver for Highs. The other design would be a dual 15" 2-way cabinet. I really like the sound of three way cabinets such as the 4628B's from JBL's cabaret series (Stuff that was out before I was even born). They sound smooth and dont blast people when you place them close to a crowd. We all know that a double 15" can throw out a whopping amount of bass, but can sound harsh when using a 2 inch throat compression driver for hi mids and hi's. In your opinion, what would you pick and why???
