OmniTop 8 is our narrowest horn loaded PA top, for when you need a high sensitivity line array capable cab with a slimmer profile than the OTop 12 or DR200.
OTop 8 is loaded with two 8 inch woofers, with the same high frequency options as the OTop 15: dual
compression drivers on a CD horn as pictured, a 10 element vertical tweeter array, or a 20 element melded tweeter array that gives high frequency dispersion and pattern control that no commercial PA top can match.
The black trace on this chart shows 1 meter/2.83v sensitivity loaded with a pair of Eminence Beta 8 drivers and a 20 element melded array:
The 80Hz lower usable frequency limit allows the OTop 8 to run without subs when you don't have to reproduce a lot of bass content, as in acoustic acts.
The blue trace on the chart is a pair of 8 inch loaded JBL VRX 928LA cabs. Because their woofers aren't horn loaded they come in way shy of the sensitivity of the OTop 8. They aren't shy where their price is concerned, at $1450 each. You can build an OTop 8 for less than $300.
