the HPR used the RMX amps


True, the HPR amplification is based on RMX. The KW series uses the 500W+500W class D amp plus universal switch-mode supply module from the K series. The K and KW series amp modules also use DSP, but there are no QSC digital amps.




That figures LOLS I thought that the GX line was a digital amp!

KW is to be a replacement for HPR. They will be manufactured in Costa Mesa.



Will they have flypoints like the HPR's do?

And the K Series for that matter.

Actually QSC's website says they do.

Did anyone else notice this?

The 3 way speaker (KW153) with a 15" driver is rated down to 35Hz

and the dedicated sub (KW181) with an 18" driver is only rated down to 43Hz

seems odd to me.

Just because they list 35Hz doesn't mean it does it with much volume.

This is no different than their HPR series.

HPR153's  @-3db are 35Hz to 18kHz
HPR181's @-3db are 45Hz to 95Hz  

Speaking from experience, I loved my old HPR153's. They put out nice clear sound... and extended nicely into the low range. But didn't have the thump that adding the sub does.

Jonathan, looks like you got your labels backwards.

Durrr... saw it now.  I went straight for the spec sheet which doesn't mention it.

I'll be honest and say that I am a little bit worried about losing HPR to something K series related (not to knock K-Series, it's the best in it's class by far in my experience) just because I've had such great experience with the HPRs and have used them on various installs.

HOWEVER, I'm holding off judgement until I can actually hear/use these.

Oops,  but only by a small margin.  

Corrected figures:
HPR153's  @-3db are 41Hz to 18kHz
HPR181's @-3db are 45Hz to 95Hz

The point I made still holds true. With the HPR's and the new KW's The 153 still "technically" drives lower.... but doesn't do it with the "thump" and volume that a dedicated subwoofer does!

The speaker loses response OUTSIDE that range of values, not between those values.

Alright, then why would you need a subwoofer then?

There's two answers possible  --  

1) The marketing folk are inflating numbers.

2) Something sonically is happening.
