- I have an NAD integrated amp that has two sets of speaker outputs.
- When I set the speaker select switch to A+B, the amp wires the pair
- of speaker sets in parallel. I have a pair of 6 ohm advents hooked up
- tp the A terminals. Now, here comes my question->
-
- Lets say I take a single voice coil subwoofer driver, mount it in a
- correctly dimensioned accoustic suspension jack, throw in a passive
- low pass crossover, and connect the positive to the POSITIVE LEFT B jack
- and connect the negaive to the NEGATIVE RIGHT B jack.
-
- Now, I switch the speaker selector over to B ONLY. What does this do?
- DOes the bridge my amplifier, like you can do with car amps? Or,
- does this blow up my amplifier? Do I get the sum of both channel's power
- into this hommade subwoofer? What happens?
-
- Next, I set the speaker selector to A+B!! NOW what happens?
- Does THIS blow up the amp? Remember, I have 6 ohm advents on A,
- and an 8 ohm sub, quasi-bridged on B. WHAT HAPPENS????
- What happens if I use a 4ohm driver?
-
- Thanks in advance,

- By the way, I know I can use a dual voice coil driver, or i can use a
- stereo pair of single voice coil drivers....but thats more expensive!
