Impedance and System Design
The speakers are actually selectable between either 16 ohm or 8 ohm. This is good and will help your plan to work!
A quote from Amazon's site: " . . . Dual 16 ohm voice coils; switch for 16 ohm stereo operation or 8 ohm mono bridged setup."
I am unclear on their use of "stereo" and "mono bridged" in the context of impedance.
I am reading this as 16 ohm when in SSI mode (one speaker producing both left & right) and 8 ohm when in one channel mode (one speaker producing either left or right). I could not find an online product manual to verify my understanding, and I could be reading it "backwards" from their intended meaning--read the manual carefully.
If you are unsure after reading the manual, provide quotes from the manual in this forum for additional help.
This
site might also help (reference the top two diagrams):
Assuming my read is correct, here is how to connect.
A) To get a PAIR of speakers with the impedance switch set to 16 ohm to work properly with your BA-2430, you will
wire two speakers in PARALLEL.
The reason for this is, two 16 ohm speakers connected in PARALLEL present the correct 8 ohm load to the BA-2430, although the wiring will take some patience and double checking (I highly recommend a naming convention and labels).
B) To get one speaker with the speaker impedance switch set to 8 ohm to work properly wire it normally (i.e. only two wires, either left or right).
I would do a dry run "mock up" on the floor of the living room before installing in the ceiling/walls and then run an operational test.
Run it for a while and ensure the BA-2430 is not getting too hot, if it gets too hot, double check the manual, switch settings, and wiring carefully.
SYSTEM DESIGN: The BA-2430 will support no more than four zones (8 speakers total); either four zones with two parallel connected SSI speakers each,
OR four zones with two mono (left & right) speakers,
OR a combination of the two, not to exceed eight speakers (in even number combinations).
Therefore, the BA-2430 is not capable of giving you all the coverage you initially indicated.
I added some "assumed" zones and speaker numbers (in parenthesis) as a starting point for further discussion:
Zone 1 Living room (2 in SSI mode),
Zone 2 office (2 in mono mode or 2 SSI),
Zone 3 master bath (1 SSI) & master bedroom (1 SSI),
Zone 4 hallway (2 SSI),
Zone 5 guest bed (2 in mono mode or 2 SSI)
You will either have to drop or combine some zones (such as combining office and guest bed) or get a system with more zones. Each zone can only support two speakers, either 2 SSI or 2 mono mode.
