UPGRADE ADVICE NEEDED - from my BIC PL-89's to ?

[johnny45]

which would be a suitable upgrade over my bic pl-89 towers the are my current fronts

 

which would be a suitable set with good low end at least down to 50hz that got a flat or close to response an detailed but not sharp treble

a pair of Monoprice Encore T6 Tower Speaker
or
a pair of Klipsch RB-81 II (would also match my the one in use as center )
or
a pair of Airmotiv T2+ (bought vi monthly pay options)
or
a pair of CCB-8

these are my options that i could put the cash to gather for

 

my receiver an amp are the outlaw audio 976 4k balanced receiver an crown xls 1502 amp

 

so power an audio calibration isnt a issue
