Don't sweat the cost of the speakers. Mine were virtually free. The previous owner wanted to give them a good home. I have built my system around these speakers to see how much I could get out of them (Belle Klipsch 1978ish).
The Townsend "bars" (they were too big to afford podiums) was the best investment I made for the money. The new crossover helped too, but more expensive.
Go for it!!! Try the bars if you don't want to spring for the podiums.
