Chesseroo and fhw, there's still an incomplete understanding about the sub crossover if the choice is to set "small" on the receiver. Again, it would be best to completely bypass the sub crossover, if the sub has that option. Otherwise, the sub cross should be turned up to the max setting to get it as far out of the way of the 80-90hz receiver cross as possible. The sub cross should definitely not be set in the 80hz area, this would only result in interference between the two crossovers. The sub crossover should never be turned down from the maximum setting. If there's excessive bass, this has nothing to do with the sub cross. It's the sub level control which should be turned down to reduce the bass.
