How To Measure Speaker Impedance And Other Specs

Welcome to Speaker World!

“I like my freedom, what can I say”........as do we all John, as do we all

DUDE! Loving it. I think it would be a popular series. Even kids want to build speakers, it will probably give them some woodworking skills.

It's really cool that you know all that stuff about building speakers and how they work.

This video was awesome. Thank you!

Nice video John! Thanks for sharing with us!💖👍👌😎JP

Thank you Professor Heisz that was a very enjoyable lesson.

This is stating to get interesting! Back nearly 20 years ago I used a book on speaker enclosure building to calculate the volume of a box and its ports to make a big woofer. They were only cheap 300w subs, but with the right box they really kicked! Looking forward to seeing the final results.

Morning Teacher! :-)

You are a good man :)

Very interesting

Hi thanks for your nice video! Could you tell what system is that (little box & software) you used to determine the speaker impedance? Many thanks!

Once you get this finished I would like to see how it would do on your other channel. Finished in a nice cabinet or open baffle I think that it would do quite well. Hopefully it would encourage a wider audience to push outside of their comfort zone as well as to exercise some problem solving. We need more of both.

I have rigorously tested at least three different models of the Dayton Audio DATS, including the latest, Version 3, which features a black box. Unfortunately, none have provided reliable results. When comparing the data obtained from these devices to manual test outcomes for Voice Coil resistance, BL, Cms, and resonance, there is a significant discrepancy. My approach to testing has been meticulous: I constructed a specialized test bench designed to securely hold the woofers without any vibration. This bench is considerably heavy to prevent any overlap between woofer and bench resonances. Despite these efforts, the system's accuracy leaves much to be desired, falling far short of being either accurate or approximate.

I have very little idea what you’re talking about but I like it.

FREEDOM!

If you have 2 identical speakers, one is rated at 4ohms/50watts and the other is 8ohms, is it safe to say the 8ohm speaker will require about 100watts to match the loudness? Also, if you have an amp rated at 8ohms/100watts per channel can it run a 4ohm/50watt speaker safely?

Hi sir! Can we do impedance sweep for 4 boxes which is connected in parallel?

Oh I love speaker world speakers are my friends

i was watching one of your old videos are you still using your old wooden pc in your office and is the pc remaining cool also what is the over all size thank you. I would like to build one since it is hard to find a good case.
