 <\/p>\n

I have written a small review<\/a> on the Zaph Audio ZA-SR71<\/a> loudspeaker design. The ZA-SR71<\/a> is a popular and a well-regarded design among the DIY community and rightfully so.<\/p>\n

The ZA-SR71<\/a> is both technically well-designed and a good performer sonically, paired with a high performance\/price ratio.<\/p>\n

I have personally built and used the ZA-SR71<\/a> for some years now and I listen to them from time to time and I still enjoy them. I\u2019ve used the ZA-SR71<\/a> as a sort of DIY reference loudspeaker and sometimes used it to benchmark other loudspeaker designs against.<\/p>\n

I\u2019ve made a small modification to the original ZA-SR71<\/a> regarding the enclosure volume. I found the 14 liter enclosure way too small for the Seas ER18RNX mid-woofer and I increased the volume to 18 liters. Besides that, I\u2019ve used exactly the same cross-over and the same cross-over components sold by Madisound in the ZA-SR71 loudspeaker kit<\/a>.<\/p>\n

In my review I\u2019ve measured the driver units individually and the measurements includes, T-S parameters, distortion, impedance and frequency measurements as well as measurements for the finished design.<\/p>\n

Please visit Zaph Audio<\/a> website for the full ZA-SR71<\/a> design documentation regarding cross-over schematics, tuning options and the designer\u2019s comments to the ZA-SR71<\/a>.<\/p>\n

I\u2019ve also made some cross-over simulation based on my own measurements to show some effect of changing the listening distance to the loudspeaker as well as showing the driver units cross-over slopes and phase behavior etc.<\/p>\n

I think John Krutke (Zaph Audio) made a very nice DIY loudspeaker design with the ZA-SR71<\/a> and I just want to say that this review is my personal opinion and is based on my own sound preferences, measurements and design views and shouldn\u2019t be consider as criticism to another loudspeaker designers design choices.<\/p>\n
