Volume dropping/bsc filtering

I tested my Jerikohorns(only one of the speakers) with a bsc filter from MJKings webside http://www.quarter-wave.com/Project05/BSC_Circuit.pdf
The volume dropped dramaticly on the filtered one and when i switched to the unfiltered speaker it was way louder. I had to go to work and did not have time to try other setups but i was suprised ower the low respons when filtering and hope someone can give me advice. If this is it, i have to get a more powerful amp.
In the cirquit it is an paralell with a 15 ohm resistance and 3uf cap. Is this for imp correction? Is it a optional part of the filter or specially composed for the ml-tl speaker project it is meant for?
Thank you!
Espen
