I did some testing this morning by connecting and disconnecting the speakers from the amps. The speakers connected in series (two speakers per channel chained) sound different from what they sound when they are connected separately (single speaker per channel). Interesting, that while both speakers in series produce a duller sound, one of the speakers degrades the sound more than another. Unless it is OK to connect them in parallel I would have to loose one pair from the system as it appears a single speaker per channel sounds way better.
Chained speakers signal connected in series
I have two pairs of the same model speakers (Tannoy SGM 10B) connected in series to two monoblock amplifiers. The left channel amp drives two speaker cabinets on a left (speakers L1 and L2) and the right channel amp drives two speaker cabinets on a right (speakers R1 and R2).
The positive speaker output of the left amp is connected to a positive post of the first speaker L1(+). Then the negative post of the same first speaker L1(-) is connected to positive post of the second speaker L2(+) with the its negative post L2(-) connected to the amplifier's negative speaker output.
AMP(+) > L1(+)
L1(-) > L2(+)
L2(-) > AMP(-)
Both left channel speakers have a cross-overs build in. Does the audio signal that the first speaker L1 receives from amplifier is any different from a signal the second speaker L2 receives from speaker L1? Does the crossover of the first speaker L1 modify the output signal that goes to a second speaker L2?
