Question about Infinity BU-1 Speaker
In general higher speaker impedance is safer than lower impedance for the amp. Don't expect anything impressive re: audio output from a passive (unpowered) sub if your HTS says it pushes only 25 watts. Without frequency bandwidth and distortion noted the spec is virtually useless as a comparison.
The BU-1 is a powered sub that accepts either RCA Line Level or HIGH LEVEL amplifier power. If you use the latter, impedance is a non-issue because the input feeds the BU-1's internal amp, not the speaker directly. You should be okay.
Perhaps if we knew some specifics about the HTS we could do more than guess.
