air coil is usually very good quality, but this coil has dcr 2.08ohm which is not good.
Low pass: the problem is high DCR - it has a big impact on the quality of the bass. The amplifier does not have full control over the woofer, the bass can sound muddy. Another problem is that you will lose power, almost 2db.
High pass: 12db/oct. capacitors in series and the coil in parallel with the speaker. And here too the big problem is high DCR! Th...
air coil is usually very good quality, but this coil has dcr 2.08ohm which is not good.
Low pass: the problem is high DCR - it has a big impact on the quality of the bass. The amplifier does not have full control over the woofer, the bass can sound muddy. Another problem is that you will lose power, almost 2db.
High pass: 12db/oct. capacitors in series and the coil in parallel with the speaker. And here too the big problem is high DCR! The coil has the task of blocking the remaining low frequencies to the ground, but when the coil has a constant current of 2ohm it cannot effectively block the remaining frequencies so the passive crossover will behave like 7-8db/oct. Summary: acceptable for low frequencies but not good! For me it is a waste of money and time.
