I notice that the recently-announced QSC KLA181 subwoofer still has pitiful low-frequency extension. As a product that looks like it ought to be positioned in the same market segment as the JBL VRX, I remain dumbfounded by the apparent absence of a QSC subwoofer with additional LF bandwidth, especially given that JBL is now pushing this feature, and the concept of LF extension, to buyers with the PRX618S-XLF.
I also find it surprising that the polarity switch is touted as a feature for creating a directional subwoofer array. Will there also be a delay control? I notice that a switch to configure the array for the number of boxes used is included, a nice touch which likely activates much, much more sophistication than the simple HF pad in the JBL VRX, which is looking more and more like a legacy product in need of an update.
I guess we won't know much more until the products ship and someone buys or demos them. Perhaps Bob Lee (QSC) will come along to provide some additional points of information (delay knob?) between now and then. I am also curious if it uses the same drivers as the K/Kw-series.
Now that more of these ''looks like a line array'' constant-curvature products are reaching the market, and at affordable prices, more of us entry-level providers will have to start thinking about owning something that ... has a bunch of boxes in a vertical line ... whether or not that is the right or most cost-effective solution. Damn promoters!
