I'm sure someone will correct me if I'm wrong. If you read the brochure that came with the speakers, I believe it states only to remove them if you plan to drive the woofers seperately from the tweeters/midrange, or bi-wiring. If you take the bridge out, depending on which terminals your using, I don't believe you'll be driving one or the other. My guess is that you are driving the tweeter/midrange, otherwise you would definately notice a problem. So, if your woofers are not getting any juice, you probably have a sub that is picking up the low frequencies, that is why you didn't notice. Once you hook up the bridge, you should notice a huge improvement. Make sure you have your crossover set right.
