My friend bought the latest QSC subs and they are better than the KW subs. You won't be disappointed for sure!

Sorry I'm so late on this review,

Yes, I would say that they out perform the KW181's, They will definitely put out a large amount of bass. I used them in 1/2 of a convention center with about 100 people attending a Christmas party and 2 of these was over kill for this event. I never got them much over 30% and that was all that was needed.

Now let me add that I did not know that these subs will not cross over and send only a high pass signal, they will only pass a full range signal and this is not what I was looking for in a sub as I use different tops and some of them do not have any type of crossover in them. Now at this event I was using my K-12's and used them in the with sub mode.

Over all easy to move around and load, tons of bass with extra headroom, so if you don't need better processing that these provide, then you would be happy with these.

Not sure if you use K12 or K12.2, but on the K12.2, if you use the "80 Hz KS" option in the Sub Menu, it should work properly coming off the subs thru outputs. On the K12, use the "EXT SUB" setting and it'll work, though the rolloffs are slightly different (80Hz vs 100 Hz).

I was using the older K12's and the Ext sub is the setting I used. I prefer that the crossover be in the subwoofer and just jump to the tops as I can do with my RCF 705's. But the KS118 will not do this. Like I stated I use other tops with my subs and some of them do not have any crossovers built in them.

There is a crossover in the subs .. just not a high pass to the tops .. but the QSC tops have that as an option on their input, so it works out to be basically the same thing. Only discrepancy is the one in the sub is at 80Hz, and the one in the older K is at 100.

I see. Why not stick with RCA and go with the 708's? Is your system mixed already?
I have both QSC and RCF speakers and I had the chance to demo the KS181's so I thought I would give them a try, and I have a connection for QSC and can get a much better price for them, but the NO high pass on the QSC will make me look else where as I sometimes have to mix different brands of tops and bottoms depending on the event.

Oh well no harm, the QSC KS181 did sound great but just won't fit my needs.
