I have been making project speaker cabinets for a few years now, and I have decided to start doing small time sound reinforcement for local bands. I can make a decent sounding speaker and enjoy doing so. Do you guys think that it is worth it to build my own cabinets for my live sound gigs, or is it better to go with store-bought cabinets????

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???

The wood for the boxes, with out paint and handwork, can also vary from 1 to 10 fold depending of the quality. You end-up with one much better vue of the final price if you put it all together. Now I understand why the speakers from good factories come with bad xover parts.
