Frequently asked questions

What types of loudspeaker drivers can this program simulate?

The FINEMotor program is ideal for simulating and designing the magnet system and voice coil for any kind of loudspeaker driver, including woofers, domes, telephone receivers, and headphones.

What is the recommended minimum impedance for a nominal 8 ohms system?

In a nominal 8 ohms system you can often go down to DCR= 5.5 ohms (or even lower) and still keep the minimum impedance of 6.4 ohms.

What is the maximum linear excursion for the ~10mm winding width solution?

For the ~10mm winding width we get a Qts of 0.45 and (linear) Xmax (Xmlin) of 2.35mm.
