Waveguide Question

Thanks, Jim.

I get it now... the CDWG passive radiator pieceis to attenuate the LF response to better match the waveguide-attenuated 10Khz HF response. Makes sense. It is separate and separately priced because some may want to use a different approach, a couple of which (active parametric EQ, tweeter mounting config) have been discussed here.

Thanks for the info.

The RM/X is currently in stock at $14,900 plus TRT's if desired.

Your humble servant stands corrected, your Excellency.

Are any of you CDWG users experiencing a warmer (less "hot" or "blaring") overall balance to the RM40's? I've got my midrange panels surrounded by 4" wedge foam (thanks to Casler, et al, of course!)...

Thanks,

I'll tell you what I just noticed, watching Law & Order. Normally on non-CDWG equipped 30s, when the string section comes in for effect, it sounds very muscial & dramatic, the way Dick Wolf wants it to. But not a lot of seperation between the sections...nice, but still a bit homogenized.

I'm watching a pretty good dramatic episode from last night, & for a change of pace the political/social slant is in a direction I favor, making it all the more better. I am not paying any extra attention to the score.

But a few seconds after the strings come in...woa! I can't believe the string texture...the effect of horsehair pulling over the strings is immense, the sawtooth waveform & 9th harmonic so cleary portrayed. But the biggest surprise is the seperation between sections. The violin, viola & cello sections seem perfectly highlighted & in distinct locations, with crystal clear precision. Yet there is no excess detail, attention or stridency, & the dialog blends with clarity for the most incredible effect. Musical bliss. And this is on VHS hi-fi!

Jimmy likey! B you kicked butt with these things.

Skynard: Get yourself a Behringer DEQ 2496. You can adjust the sonic presentation any want it. It works wonders with any room/speakers and is a killer bargain for what it does. I'm not kidding! The sound in my room is amazingly good and even though I've got an LEDE room with bass traps the Behringer unit took it to another level.

All rooms will have hot and cold spots depending on speaker position etc. Now you can tune to your room without a penalty.

How do you have the foam wedge? Is it connected to the wave guide?

There is no need to use the foam behind the CDWG (nor is there space)

It already has specific layers of treatment that fit up against the neopanels.

John,

How are the midranges surrounded by a foam wedge? Glued to the outside of the CDWG?

There is no "foam wedge" on the CDWG, The earlier poster who uses the foam wedge has no Wave Guides.

Ah, I got totally confused. I thought this was a special combination of wave guide and wedge. You mean to tell me you don't have a tweak for the waveguide yet?
