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 300 bucks. Check out the 1m/1W SPL chart, which compares the DR280 to one of the better PA cabs on the market, the EV T252:

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.

Need to bi-amp? DR290 combines the LF section of the DR280 with the HF section of the DR300. Both HF configurations are included in the plans.
