    (Semi-)commercial Amplifier - bridging, parallel, impedance, and adding speakers

    This question is mostly about amplifier output impedance I think, although the actual kit in use is not normal domestic! Hopefully it's allowed. A friend has a small-scale semi-commercial amplifier feeding her work-from-home business audio. While it's shut down she's thinking about expanding...

    Subwoofer Impedance Speaker Out Doubt

    Hi everyone, I'm trying to set up a 2.1 system which is a Frankenstein of different components. My amp does not have a sub out port, so I'm forced to use the speaker in/out port of the sub and from there I will go to the speakers. Unfortunately the sub does not state the impedance of the...

    Is this amp good for a Wharfedale Diamond 220?

    Not really sure how amps+passive speakers are matched up well Was hoping people could shed light on if this BT20A could support the 220s well? Link to the Wharfedale Diamond's Sensitivity (dB) 86 Impedance (ohms) 8 Power Rating (Watts) 100 Freq Response (Hz) 56 - 20,000...

    Question Pioneer A300R - Basic Headphones Sound Terrible

    Hi Folks, I use a Pioneer A300R amplifier (the Tom Evans "Precision" variant) that I recieved as a hand-me-down from my dad a few years ago. He purchased this amp back in 1989 (before I was born!) but it is still working very well. Since inheriting this amplifier, it's always worked well and to...

    Question Impedance setting on Marantz NR1608

    My amp manual is a bit limited on this topic, and the information I’ve found on the net is a bit confusing - should I set it to 6 ohms or 8+ ohms. If I understand correctly, it should be 6 ohms, but I don’t want to go blowing things up. I rarely need to operate the amp at even close to 50%...

    Question Denon AVR 3805 Subwoofer rating

    Hi All, I was looking to buy a subwoofer for a used Denon AVR 3805 I just got. However, when I went through the manual I could only find the wattage and impedance rating of the 7 channels, not of the subwoofer. Should i assume that the subwoofer has the same rating or am I missing something...

    Question Speaker impedance help

    Hi, I'm looking for a wee bit of advice regarding my horrifically mixed and matched setup. I recently got a shiny new Onkyo NR656 in their exchange program for a knackered NR606, and since it is Atmos capable, I would like to try it out in a 5.1.2 setup. I currently have a pair of very old...

    Speakers impedance

    Hi, I have a question regarding the impedance of speakers. Lets say we have an 8 ohms speakers 4 way, 1 woofer, 1 midrange, 2 tweeter all of them are rated at 8 ohms impedance. As I read in many forums that the impedance will be added if speakers are added in parallel. I looked up a lot of...
