Question about Recoton Advent Advent AS2 Main / Stereo Speaker
I have a pair of Advent AS2 speakers. They sound great, but I have blown amplifier outputs on 2 seperate receivers with them. I measeured the Impeadance on the woofers alone, and they are producing a 4 - 4.5 ohm reading. The tweeter produces a 6ohm reading. I removed the jumper plug on the rearspeaker binding posts (for bi-amp) and took another reading...4 ohm on the woofers at the woofer terminals, and no reading on the tweeter terminals. The rear of the speaker cabinet says 8 ohm ! Am I crazy?? The speakers sound awesome, now hooked up to a 4ohm Samson 85 watt per channell amp. I also placed a tone generator on both sets of terminals...bottom post produces tone for both woofers, and the top terminals produce tone through the tweeter.
SOURCE: Lost woofer in one cabinet.
I'm not familiar with your specific model, but some of these have fuses for the woofers. Check for a blown safety fuse. Also, verify that the connections to the crossover board are in good shape. These crossovers are not that complex and don't usually fail. Keep us posted on what you find.

Ohms law I=V/R which is 240vac divided by 3 ohm = 80 amps. Dead short which is either the windings, or the mains filter capacitor which has gone short circuit which is more the likely culprit. This is on the output side of the fuse. If you have a meter switched to ohms and measure across this capacitor you will read zero ohms (dead short) which confirms the capacitor. Disconnect one side and if the short goes, then it's the cap, if not, it's the transformer.
