    My bike is clone - Nopsa Fleur. Third similar structure bike was Tunturi Poni. Original Jopos had a pressed steel frame that was welded from two left/right mirrorlike sections and a hinge. Modern ones have ovoid tubular frame like Poni and Fleur. The idea was to make it fit for children from 10...

    Linkwitz LX521.4 Review (and measurements!)

    Multichannel DSP is needed to match acoustic delays of signals from each channel. This should be done outdoors without room reflections, but including floor in case of a floorstanding speaker - mic located on ground at 3 meter or more, speaker tilted. indoor at 1m is ok above 400Hz. Dip between...

    Yamaha WXC-50

    https://usa.yamaha.com/products/contents/audio_visual/downloads/manuals/index.html?l=en&c=audio_visual&k=wxc-50 AUX IN goes through the preamp just like digital inputs. At least volume control works in my units (2) I don't use them regularly, so I had to attach a DAP... With web browser...

    Yamaha WXC-50

    WXC-50 has a little switch on the backside panel, which enables volume control. Turn it to "Preamp"

    Measuring Some Vintage Speakers

    Smoothing of spl graph is very helpful. Most publised data use 1/12 or 1/6 octave smoothing. But 1/3 or 1/2 oct match best with listening impression Gating time makes a difference, look at my pics here. Frequency-dependent windowing FDW removes some artefacts. Here 15 cycles which seems to be...

    Measuring Some Vintage Speakers

    About reflections and room modes... One can "see" modes easily from REW wavelet spectrogram. Second is waterfall with default settings and third is raw impulse. In impulse wiev you cannot see the frequency, only timing and magnitude of reflections. Below bconline's measurement of Revel ant...

    Measuring Some Vintage Speakers

    Some users were worried about loosing high freq accuracy with long gating. This will not happen noticably! Here animation of my indoor small room responses of same 0-15deg off-axis measurements. Same data but different fixed gating, same right window type. And distortion of same on-axis...

    Measuring Some Vintage Speakers

    Seems like your noise floor is too high to evaluate distortion. Something in the room resonating at 120Hz? Some gadget making noise and distortion at 1kHz? Anyway nice effort and fun to follow! Please spend some time to tune your technique - do lots of tests with various changes - one at time...

    Measuring Some Vintage Speakers

    bconline and napilopez, please show also distortion dB from REW! THD plus 2nd to 5th harmonics - and noise floor. Looks like your amp had same voltage/gain setting Actually distortion dB and fundamental is enough, it uses variable gating I guess, and presents on-axis spl very well in same pic...

    Here's my baby sleeping... The weather has been terrible, either -20C or 20cm more snow - I guess I rode it in October the last time. Skis are more practical now... Crescent 24-speed SUV with mechanical disc brakes. I bought it after my Nishiki was stolen 5 years ago.

    Poor man's directivity response measurement technique

    Nice, but what is "new" here? Impact of distance was interesting and new evidence to me, because "normal" speakers and dipoles behave much better. I have been using REW since 2012 and overlaying measurements is very basic. Indoor measurements present a challenge from reflections, gating is...

    Recommendations needed for a replacement for a miniDSP active crossover

    I have no regrets moving to pair of 2x4HD from the broken 4x10HD. If I remember right it doesn't accept 4x10 xml file (less channels and different sw). At first I set parameters as same as 4x10 manually, but I have tweaked them when I got a new mic. I use REW to measure acoustic response...
