Try baxglobal baxsavers for shipping large items. They are not competetive for smaller shipments (except overseas) but for inner-state shipments of larger items they are hard to beat.

Mike the 803B is an exponential 300 cycle 8 cell horn. The 8 refers to the # of cells and the 3 to the cut off frequency. For example the 1005 had 10 cells and a cut off 500 cps. The 803 was used for the theater with 1.4" compression drivers like the 288s and a low frequency enclosure like the 825,210 etc for full range sound. Also was used as a voice announcement type speaker without the LF unit using the band limited 290 series "giant voice" drivers. Although they do comfortably allow a lower cut off freq than 500cps they were often crossed no lower because of the reduced power tolerance of 288s below 500cps. But for home use this should not be a problem. You will likely also find a more limited high freq response from 288s in this 300 cycle horn than in 500 cycle horns and may indeed find a tweeter useful. Worse of all is the fact that they are beyond the size limits of UPS and Fed Ex
and therefore expensive to ship.
