    SPL under 100 Hz

    What kind of speaker? Looks perfectly normal for a bookshelf model. Regards, Wayne

    Life expectancy of a subwoofer

    There is no advantage to using exclusively negative-gain filters with capable subwoofers. When you turn the sub up to reclaim the overall volume level that was lost, you’ve lost as much headroom as you would have if you’d used boost filters...

    Life expectancy of a subwoofer

    Not sure I get the question. If the sub signal from your interface is maxed, then increase the level with the sub’s gain control. Seems painfully obvious, so I’m guessing I’m missing something? Regards, Wayne

    Subwoofer amplifier options.

    The clip light shows the input signal is too hot. If you can’t get enough signal, try moving the input sensitivity switch on the back panel to the other setting. Regards, Wayne

    Measuring BT speaker for university assignment

    Moved to REW Forum. I don't know that REW can measure dynamic range or dispersion. Hopefully others will weigh in to help with the rest. Regards, Wayne

    What is the soundcard? Regards, Wayne

    Strange measurements

    Check the graph settings under the “Limits” icon. You may need to broaden the SPL Top and Bottom settings. Hopefully John will weigh in for the other problem. Regards, Wayne

    Should I use different setting? Or - how does this look?

    Looks good, but I expect that you went overboard with the equalizing. I mean, with the second graph you had a built-in house curve going in. All it needed was an adjustment for the small peak at ~68 Hz, and perhaps a slight, broad cut at 20 Hz. The goal is not to get a picture-perfect graph...

    Large room, multiple uses, wondering about speaker position and REW.

    Assuming you’d be going with the speaker arrangement /location discussed in my previous post, the kitchen may be too far from the speakers to deliver a cohesive listening experience. I’ve traditionally had the best luck locating subs in a corner with uninterrupted wall lengths in both...

    Large room, multiple uses, wondering about speaker position and REW.

    Regardless of the speakers’ placement relative to the wall, reduced bass output is going to be an issue simply because of the size of the room. If you mean the wall to the left of the windows, I definitely think that’s worth investigating. In order to “use REW to explore this situation,” its...

    how does this sweep look? any suggestions

    Looks great! However, ultimately you have to judge a house curve by the way it sounds. With music, high bass notes and low bass notes should all sound like they’re at the same volume level, as should all the notes in between. If you don’t have the right curve for your room, the bass won’t be...

    tuning soundsytem

    Certainly can’t hurt to do what you’re thinking, but don’t be surprised if you find it wasn’t much help once you move everything indoors. Regards, Wayne

    Help choosing a DSP processor for an all analog 2 channel system. MiniDSP 2x4HD is not my taste.

    You can attach REW .mdat files to your posts. Look for the "Attach files" icon below the text box. Regards, Wayne

    Help choosing a DSP processor for an all analog 2 channel system. MiniDSP 2x4HD is not my taste.

    With no details on how you’re using or implementing the miniDSP, and no graphs to see what you’re calling “lots of dips and peaks” look like, all I can do is speak in generalities. It’s possible you’re going overboard on equalization trying to get the magical ruler-flat line. It’s possible...

    Help choosing a DSP processor for an all analog 2 channel system. MiniDSP 2x4HD is not my taste.

    I can’t tell from your equipment list how you could utilize the miniDSP in your signal chain, since your integrated amp does not appear to have both pre-out and main-in connections or bass management. Regards, Wayne
