I'll be ordering in-ceiling speakers pretty soon now. I have two different goals:
- Providing a second zone for ambient music in an L-shaped kitchen / dining area
- Surround backs for home theater use in a location with no back wall nor place for standard speakers
As my home theater setup is already equipped with Energy RC-series speakers, I was pretty much set on either the Energy RC-6C or RC-6Cst, which are both available at Crutchfield.com. Now I'm not decided between the two, and I have several questions that need answers before I feel comfortable placing the order and installing the stuff. The RC-6C are standard in-ceiling speakers with an aimable tweeter. The RC-6C are so-called "stereo" speakers with double tweeters, that can be either fed with two channels (L/R) or with a single one, in which case they can be set either to bipole or dipole mode. Of course they're also 50% more expensive, but only so much that they're cheaper than a pair of RC-6C.
As I see it, I have these options for the home theater:
- A pair of RC-6C
- A pair of RC-6Cst in dipole mode
The second option is tempting but in most 7.1 setups, the dipole speakers are placed in surrounds position, not surround backs; or in all surround positions. I already have monopole surrounds and I don't see any reason not to use them, nor am I willing to replace them with other in-ceiling speakers. Considering this, is this a wise idea to use dipole in-ceiling speakers for surround backs, or is it a waste of money?
For ambient music in the dining area, the situation is more complicated. The room is not large by any mean but L-shaped, with the long dimension being 20' and the small one about 13', with 8' ceilings. Because of the L shape the room is probably something around 1800 cu. ft. or less if we exclude storage space, cupboards, etc. Here are the options I'm considering:
- A pair of RC-6C; but where to place L and R channels in an L-shaped room?
- A single RC-6Cst in stereo mode at the elbow of the L
- A pair of RC-6Cst in dipole mode to provide a more diffuse sound; not sure where to put them
- A pair of RC-6Cst, each in stereo mode, one in each leg of the L
The last option seems the most logical but it is also the most expensive and troublesome. I'm not sure how to wire two stereo speakers. I guess they would basically act as two pairs of standard speakers -- the RC-6Cst are rated at 8 ohms but I'm not sure if there is any change in impedance when they're used in mono or stereo mode. If I want to use multiple RC-6Cst in stereo mode, I guess the best way would be to wire them in parallel, and use an impedance converter (e.g. impedance-matching volume control in-wall)? Is it worth the trouble versus just using an L and R channel considering the size of the room?
Thanks for any hint or opinion on this.
