However, the Allen at Prince of Peace also sounded quite underwhelming before it was revoiced and new speakers added.
The people at church who were on the organ committee (or otherwise involved) say they talked to the "professionals" and took their advice. They say the organ was installed according to the dealer recommendations. The people at Case Brothers said that they advised against installing the organ with so few speakers and they also advised installing the speakers in organ chambers. I don't trust either one of them, but I trust Case Brothers less. I've seen other examples of their work.
One thing is constant, people paid top-dollar for an Allen organ they thought was the best and they got crap for an installation, including no-name speakers. The difference is, some of them were apathetic, or ignorant and never fixed anything. Others paid to have their organs fixed. In order to have the bad audio system and trashy voicing fixed, they have to pay thousands more to get it done the way it should have been done in the first place.
