Everywhere on the internet, people are using these for small enclosure computer speakers or bluetooth speakers. So i have a different take since I used this in car audio. My car has a 3.534; on the dash. I was originally going to use a coaxial but decided against it. However, All the well known midrange speakers from car audio brands are up there in price. This woofer was reasonable in price so I gave it a shot. Pros : super clear. More full sounding than most 3 inch speakers. free air, I was able to cross at 140 Hz high pass with a good result. Low pass was set at 6500 hz 12db/oct Cons: it's not true full range, it needs to be crossed as part of a 3 way system

Dayton Audio ND91-4 3-1/2" Aluminum Cone Full-Range Neo Driver 4 Ohm
Dayton Audio's ND91 aluminum cone full-range drivers are the latest addition to the acclaimed ND Series high output/low distortion neodymium transducers. By increasing the original ND90's voice coil diameter from 3/4" to 1" and adding a copper alloy shorting ring, the ND91-4 features even lower distortion and delivers better bass impact and dynamic range—with peak Xmax up to 25 mm!

This high-BL version further exploits the low distortion characteristics of the Neo-Balanced motor's optimized magnetic field, making the ND91 drivers an excellent choice for full-range point-source speaker enclosures, as well as extremely accurate, high resolution line arrays.
