The Purifi Audio PTT4.0W04 is a long linear throw 4-inch midwoofer which costs about $580/pair USD. It has so much science baked in to its design that it makes my mind hurt so rather than try to pretend I understand it all, I’ll just redirect you toward the manufacturer’s website or you can view and purchase them from Madisound if you’d like.

Up for test is the venerable Scan-Speak Revelator 12M/4631G-00 4.5″ Midrange.
Some refer to this as one of (if not the) best pure midrange available. It is used in many DIY designs as well as manufacturered loudspeakers.

Up for test is Scan’s newer edition to their 10F lineage: The 10F/8414G10. This features a smaller neo magnet than it’s predecessors (like the 10F 4-ohm midrange tested here), making it an easier fit for tighter install applications.

Up for test is the Scanspeak Discovery 10F/4424G 4 inch, 4 ohm midrange. This driver features a neo magnet to keep its weight down. Accompanied with the extremely small form factor, this is a top choice for many in car audio and home audio alike. While this is noted as a 4″ midrange, seeing it in person makes it appear to be closer to the 3.5″ driver family relative to other 4 inch drivers. This is a driver I often recommend for its price vs performance over the years.

Up for test is the Scanspeak Illuminator 12MU/4731T-00 4.5" Midrange - 4 ohm.
Note: For a while I didn’t have the means to measure frequency response accurately. Rather than do it halfway I decided it best to not attempt it. So this is one of the reviews I completed at that time and thus there is no FR/HD data.
