My view on this is that if you can hand craft products there are some great advantages. I have 15 x Behringer 18 in sub woofer speakers and my main complaint is that while the speaker drivers are great the boxes are are not as well made as they could be. I have built some heavy duty boxes (but light wieght due to advanced desigh) based on thier design and the results have really been really pleasing. These boxes use loads of 45mm screws, proper slotted joints, 3mm aluminium silent grill and highest qualtiy glue and produce outstanding sound and endurance. No crappy staples used here!
