Event Speakers- How much is enough?

[D-Kem]

I've only heard the K Sub, I haven't had a chance to mess around with one myself, so you should take my review with a grain of salt. It is okay for smaller rooms, supposedly the KW181 stomps it for not much more money, I'm a JBL guy though so my preference goes to the PRX618-XLF.

Intended application is an important consideration as well, if you are looking for volume at the expense of extension and fidelity, the Yorkville LS801P is probably the loudest single 18 cab I've ever heard. It's kind of "boomy" imo, and it seems to roll off a little higher that other subs, but most top 40 and hip hop don't have anything going on down low anyways.

Yeah I own a RCF Pro 8002AS sub and it's a beast but put me on the sick for a week the last time I took it out as a 1 man lift. 56kg and an awkward shape so I need something portable but don't want to sacrifice quality and output.
I do an underground House night as well as more Generic gigs so need something that hits 40hz really. I test my sub generally with this
Sorry OP didn't mean to sabotage the thread and will stop now. I've done a School summer fair with 200 people using 3xRCF 312A's and one DB Opera 15 sub which was more than adequate. I suspect you will have enough for 40 people.

Either the KW181 or the PRX618-XLF would be better from a weight perspective, not sure about the difference in output though, as I haven't heard the RCF.

I hear you about the weight, I actually prefer to haul around a pair of 728S over the 718S because they are actually easier for one guy to load and move around.
