A delay stack is used in a PA system for a larger event in a very long room. In a long room the quality of the sound deteriates as you further down the room as sound is absorbed by people, carpet and furniture. Of course you can add speaker halfway down the room, however sound travels at approx 340 m/s or approx and the sound will be out of time. The sound from your front speakers will have an echo compared to your mid speakers and your event will sound like its a train station!

 

The solution is to add a small delay to the mid speakers to bring them back in time. I also find it useful sometimes to put a short delay on the main PA if I have a deep stage withe a drummer at the back.

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!
