A:AnswerIf your stereo has a 1/8th line out, this speaker set can work. I haven't gone to max volume with my set so can't say how louder volumes will sound.( extreme bass might get fuzzy at high volumes).
A:AnswerHello binkbonk! The Z150 2.0 Multimedia Speakers DC power plug isn't sold separately on Logitech's website, but you do have a 2-year warranty on the product, and our Customer Service sometimes have access to more parts than what's listed on the website, so I would check out the product page https://support.logi.com/hc/en-us/articles/360025074953-Warranty-Multimedia-Speakers-Z150 and choose the "Contact Us" option. They need to be plugged in to a wall outlet.
A:AnswerHello Isabelle! If your turn table has a 3.5mm line out, then you should be able to use the Z150 2.0 Multimedia Speakers with it yes. Note that the speakers also need to be plugged in to a power outlet for power.
A:AnswerHello Jamil! If your record players has a 3.5mm line out, then you should be able to use the Z150 2.0 Multimedia Speakers with it yes. Note that the speakers also need to be plugged in to a power outlet for power.
A:AnswerAs long as your HP system has an available 3.5mm audio output port, yes the Z150 speakers will work just fine. There is no subwoofer included with these, so you may not get the best audio experience for gaming from the Z150 model.
