    Seeking advice on Extending Low-Frequency Response in 70's speakers

    It is fun to think about. The woofers probably don't have any inductor on them, just a big cap running first order into the mid. Just my guess but that's how old speakers are. So you'd have to use that inductor to depress the entire passband of the woofers to extend the bass. By the time...

    Seeking advice on Extending Low-Frequency Response in 70's speakers

    The drivers have inherent limitations, getting output below 50hz would cause output to drop precipitously. Sealing airholes won't do anything and adding bracing will if anything reduce bass by reducing cabinet volume.

    Seeking advice on Extending Low-Frequency Response in 70's speakers

    Get or build a sub, visible or not. Those are very pretty speakers and I would not modify them unless they were malfunctioning.

    Review and Measurements of NAD C 320BEE PWR Amplifier

    IRS V is a bit extreme but there are a lot of 4-6 foot speakers out there which id like to see. JBL Everest and so on.

    Electrostatic speakers?

    I'm in the city, one day I hope to join you although Harvard is plenty quiet for me. I guess I did just buy an apple tree though.

    Electrostatic speakers?

    You in Harvard? One of my favorite places in the area.

    Electrostatic speakers?

    Have you taken detailed anechoic measurements of the 989 by any chance? I was always very impressed by how innovative these units were, truly one-of-a-kind, but nobody has ever measured them.

    Electrostatic speakers?

    It's still pretty fast depending on excursion but you're right. I'd pin this on directivity and room interaction differences in the 80-200 region.

    Review and Measurements of NAD C 320BEE PWR Amplifier

    What's the biggest he's done? 8361 were pretty beefy.

    Can large oil painting work as acoustic diffuser?

    Just my 2 cents, do not mix art and acoustics. Get acoustic treatments that look like acoustic treatments and art that is art.

    Mesanovic CDM65 love?

    You could argue the Mesanovic are much more advanced than any Neumann. Neumann doesn't have a cardioid speaker, nor do they have a speaker with a large enough waveguide to deliver the low frequency directivity control that makes these speakers distinct. I'm waiting for the cardioid Kali myself.

    AsciLab speakers are about to launch

    Excellent work on the passive crossover. I like to see passive models. It appears to be executed just as well as the active version. Like the mint green color, too. I bet a cream or tan colored speaker would look nice as well.

    Mesanovic CDM65 love?

    I see the mesanovic stuff as competition to D&D almost, lots of lifestyle features. Those amazing new purefi speakers from Korea will be in that category as well when they come out. Incidentally I'd bet the 8c would be a pretty good monitoring solution. Powerful, great room independence...

    Mesanovic CDM65 love?

    I'd assume the conventional choices have better bass management solutions, easier integration with digital interfaces like Dante for multichannel and so on. If it was my job to use speakers I would only be looking at Genelec. Their range of offerings from tiny to huge, history of innovation and...

    Should you use Fletcher-Munson loudness compensation?

    I think it would make some sense that a more generic, gentle, low Q filter would be less invasive than following the loudness curves exactly. It sort of makes sense not to try to nail the wiggle in the treble region, for example.

    Having been an "audiophile" for the last decade, wireless headphones are the best thing that happened to me since the beginning of the journey.

    Aka vastly improved fidelity People always talk about detail timbre and ignore the one technology that makes detail and timbre vivid and audible without employing the typical HiFi strategy of boosting the treble. Even at home, at the quietest time of day, anc is hugely impactful. Somehow it's...

    Genelec 8550A headphones

    Genelec seems to be unusually focussed on non traditional recording spaces. First they pioneer speakers with room independent response so that you can get accurate sound in a bedroom or office. Next, they offer the same level of room independence with the output levels of a soffit mounted...
