How to Order Plans



The 24"x24"x24" 70 pound DR280 is just a bit larger than the DR250, a bit smaller than the DR300.

Loaded with an Eminence Deltalite II 2512 woofer and a twenty-two tweeter melded array it offers performance unsurpassed by commercial cabs costing $2k or more, yet you can build it as shown for less than 400 bucks. Check out the 1m/1W SPL chart, which compares the DR280 to one of the better PA cabs on the market, the $2400 Turbosound TQ315:

Like all DRs the 280 was designed for vertical arraying, and has an 8 degree vertical splay angle built in. But if you're using DR280 on the backline for bass or keyboards that angle still comes in handy, tilting the cab back so you can hear it better.

Prefer compression horns? The DR280 can be built using the same dual compression horn vertical array as the DR300. Shown here is a pair of compression horn DR280s stacked as a J-Array, using the ground stacking clamps shown in the plans.

Construction Degree of Difficulty: 9 Performance Quotient: 10

Suggested Audience Size in PA Applications:

2 cabs to 300; 4 cabs to 800; 6 cabs to 1500; 8 cabs to 3000

Equivalent Retail Value: $1999 to $3499 depending on driver choice.

Recommended Sub-Woofer: Tuba 30, Tuba 60, Titan 39, Titan 48
