Measuring Four Different Compression Drivers

Continuing on from last...I look at the time domain performance of four compression drivers. I then modify one compression driver and compare the test results. This video is a series of videos where I explore the performance in pursuit of the best and most affordable compression driver for an audiophile application. This means emphasis is placed on sound quality and not necessarily high SPL, or high sensitivity. In future videos I will be looking at extending the bandwidth to achieve a lower cutoff frequency so that we can use the compression driver in the ES600 Biradial Horn currently in development. For me 600Hz strikes a good balance since it’s quite achievable to obtain output up to 20KHz with still respectably wide coverage pattern. Having one driver cover 600Hz to 20KHz will maintain that point source coherency that so many audiophiles desire for their music listening experience.

Very informative. Can I use this wood horn to measure most of the compression drivers?

I love my De250's with the Iwatta Horns !

B&C makes some good stuff!

If you're still out there, ... I wonder about your microphone placement? It seems like it's so close to the driver that the full dispersion effects of the outer horn are not captured. Appreciate any explanation you might offer.

of course, if you were to use the modified one you would want to make sure there was a devider in the enclosure so its separate from the base driver.

Did you use the dats as an amplifier to use with rew?

Sir can you tell me how to I protect my tweeter because capacitor is only bass block but tweeter can also burn in high pass

@AaronKaleniecki Год назад

does phasing matter on horn? I ask because I have a tri-amped system using old JBL woofer, horn,tweeter and some have been reconed so I'm not sure if red(+) is accurate on all three components - and while you can see which way a woofer moves when you put 9v battery to the terminals, you can't do that (or at least I don't know how too,) on a compression horn and compression tweeter

Yes, it really matters. You can test if you can measure the frequency response. Check out how here… ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qmF0YSBmgm8.html

very good video, you can pass me the measurements of the horn I have a B&C de 120 and I would like to try this horn. Thank you very much ...... Greetings from Argentina

Sorry I dint have this measurement available anymore as I’ve misplaced the files.

De250 have very good eff.

I have a pair of Radian compression drivers 3 inch diameter. I get between 5-6 ohms across the terminals. Is that a proper way to test if they are blown? Neither makes sound but my boxes might have other issues. Thanks

@rcfaudioitalia6110 10 месяцев назад

Should read 6.4-6.6 ohm. that's the normal impedance

@rcfaudioitalia6110 10 месяцев назад

With emery paper, rub the inside of the kapton former, until it's thin enough. you'll get better response.
