Alon model 1 problems

I recently purchased a pair of Alon model 1's. I'm having a hard time getting them to sound good in my listening room. My room is 14' x 28' with 8.5' ceiling. Currently they are 24" from the back wall, 62" apart. My listening position is 12' from the speakers. They did not come with the spiked feet, so I have them on (9" from the floor) speaker stands. This is currently where they sound the best. But they have a too much midrange and highs verses bass output. I have them bi-wired to a 250 watt solid state amp.

Would a separate amp on the midrange/highs help this situation, say 50 to 100 watts on the mids/highs and 250 watts on the bottom end? I've read reviews of this speaker and the reviewers raved about the bass output and the nice high end, but mine sound very hard in the midrange and highs with the bass being detached with a mid bass suckout. Another problem is volume, when they are brought up to around 87dB the midrange driver starts popping. Shouldn't these play louder without problems?
