    Scandyna Blue room Minipod Speaker (in-room) measurements... I'm confused...

    Are they meant to sound this way? Like the measurements below, they are pretty dull on the high end. Do the measurements look like they're broken in any way? If they're not (both speakers measure similarly), what could the consideration be for such a sonic design? I've no idea what generation...

    Raw driver reviews with measurements?

    Anyone else interested in seeing ASR add raw driver reviews with measurements? ASR already has the required equipment perhaps with the exception of a IEC baffle but that's an easy afternoon build. I think such objective reviews would be of great benefit to the DIY sector of the audio community.

    Question about output impedance measurements/recommendation for IEM dac/amp

    Hi there, first post here, I hope this is the right place to post this I've been reading a fair amount of headphone amp and dac/amp reviews on this site, and I've noticed that the output impedance measurements on products I've looked at are usually well above what they're advertised as (Fiio K5...

    I have compiled a massive 'subwoofer comparison' spreadsheet. So far, I've found +1600 subwoofer models in total and +300 models with CEA-2010-A data. But there's a lot of interesting subwoofers that weren't tested. I'd like to see a discussion thread dedicated to which subwoofer models, we...
