Hi Gents,
Sorry for not posting but I've been very busy with work (two trips to HQ in York, PA in 3 weeks, and a trip to the Yukon in the last 6) and family duties. Almost no time for this hobby. But you've got to earn the $ to buy the toys.
I received and connected my new Front Speakers (HSU CCB-8s), I didn't bother with my SPL meter as I was too eager
to hear them, but I ran Audyssey in all 8 locations. I had to raise the TV a few inches (and modify the stand) to accommodate the Center as it was 10.5" high, and the old one was only about 6". The Left & Right are just sitting on top of my old speakers which are 25" high; until I get some stands for them. These are not close to the recommended height for the center of the cone which is 7.5" up from the bottom of the CCB-8. (7.5 + 25= 32.5" HSU is looking for 7.5 + 36 = 42.5")
The manual says:
"Positioning the CCB-8s
For smoothest response we recommend placing the CCB-8 such that the
coaxial driver’s distance to the closest surfaces are in 1:2:4 ratio (side wall
Y, floor Z, and back wall X - see Fig. 1). On the recommended 36˝ stand,
that would be 22˝ from the side wall and about 7 ft from the back wall.
That way, the dip caused by the side wall bounce is canceled by the floor
bounce and the dip caused by the floor bounce will be canceled by the
bounce off the back wall. The dip caused by the back wall bounce will be
below the recommended crossover frequency for the CCB-8.
Note that the above recommendation will result in the smoothest response,
but is not mandatory. It’s fine if the WAF factor or other practical reasons
make that impossible. Our speakers are no more sensitive to positioning
than any other speakers. In fact, due to it’s better controlled directivity, it’s
less sensitive than most."
Of course setting them "7 ft from the back wall." would cause a huge WAF issue; and therefore that's a no go zone. If I left them at 25" then according to their ratio (1:2:4 ratio (side wall Y, floor Z, and back wall X). 12.5" : 25" : 50" That's still a bit more than 4 feet out into the room. I think they are less than 2. Once I have them on stands, I'll play around more with positioning.
The 4400H drives them effortlessly. I'll dig out the SPL meter and advise some values. I bought an Atmos BluRay of the Wall (Roger Waters - ex Pink Floyd) which I'm catching in small bits at a time -not the most enjoyable way - but it's the only way these days.
More later then...
