If you're willing to go up to $200/pr, you could snag one of the last closeout pairs of Athena LS-300 towers (retail $500/pair) from Audio Advisor. I always liked the speakers from API: Good tonal balance, smooth, neutral, works well with all kinds of music. These floorstanders will also give you more of the bottom octave than most sub-$200 contenders.
At your target $150/pair, you'd be hard-pressed to beat the Energy C-200. 88dB sensitivity, bass into the low 40's/high 30's, handles up to 125 watts, excellent room-filling dispersion, good transparency and detail in a natural perspective, especially at that price.
