    Speakers with questionable "upgrades"... post your findings here.

    Another local ad. This might be a step sideways. "A pair of JBL R103 Speakers for sale. In great condition as they show little wear, and produce great sound! One notable detail is that the original tweeters have been replaced with brand new high quality horn tweeters. Overall a great pair...

    Thanks for your comments. Some of what you mention is new to me. I will investigate.

    Just read this on speaker series wiring

    I can't find confirmation, and don't recall where I read it. My takeaway at the time was that it's a good thing because it smooths our the response a bit. You won't see multiple resonant peaks on an impedance curve if you have 8 identical woofers in a box. I suppose another factor is that no...

    Getting into compact cassette for playback... Advice on suggested features and some available options

    Dolby B would be sufficient. Factory recorded tapes use B or no noise reduction. HX Pro is variable bias and is used during recording. You don't need it during playback, even if the tape was recorded with it. Some quality prerecorded tapes are on chrome, but they are always (or almost always)...

    Just read this on speaker series wiring

    I think it's a law of physics that coupled resonators (eg multiple woofers in a box with shared back space) cannot have the same resonant frequency, even if their properties are identical.

    I was listening to Living the Circle of Life (indigenous music) this morning on KRCL, so it's appropriate I found this thrifting today. Kicking Woman Singers

    Speakers with questionable "upgrades"... post your findings here.

    Local ad. This could be viable depending on the crossover, but it's likely not modified to match the driver changes. "Altec Lansing speakers with 8" woofers. The mids and tweeters have been upgraded to Polks. The mids are compartmentalized. Look and sound great! 16"d x 11"h x 10.5"d"

    Small DIY 2-way forming with JBL & C/V! drivers

    Thinking about grills, I checked out PE and saw these: They looked to be close to a perfect fit, so I got a pair. Not bad! They are thin and would have hit the SEAS domes so I swapped in the Vifa horns first and adjusted the XO settings. Might set them out a bit for more clearance but...

    Small DIY 2-way forming with JBL & C/V! drivers

    I got a couple of pairs of additional tweeters after I started working on these. See this thread… https://audiokarma.org/forums/index.php?threads/holiday-fun-swapping-tweeters-in-diy-speakers.1018098/ I probably should have done this as one thread, not two. Anyway, after brief listening, I...

    Small DIY 2-way forming with JBL & C/V! drivers

    These are running. I am using SEAS H253 tweeters. Crossed at 3k for initial testing. I set them by ear to -5 db relative to the woofers, for now. Biamped via the DCX2496 and a couple of amps that were already set up (Dynaco or “Dynacoid”). No EQ or delays on anything. It’s a coincidence...
