Definitive Technology IWSub 10/10
CHECK PRICE

There are two main factors that set how easy or difficult a speaker is to drive, these are Speaker Sensitivity and Impedance. A speaker rated lower Ohms requires more current than a higher Ohm speaker. Similarly, a speaker with lower sensitivity requires more power to reach the same volume as a speaker with higher sensitivity.

Definitive IWSub 1010's nominal impedance level is 4 Ohms . 8 Ohms is pretty much the standard impedance amongst stereo speakers and amplifiers so Definitive Technology IWSub 10/10 is not considered a difficult to drive speaker from Impedance perspective.

Definitive IWSub 1010 has a sensitivity of 0 dB. With a sensitivity level of only 8 dB, Definitive Technology IWSub 10/10 is a difficult to drive speaker from Sensitivity perspective, so make sure to choose an amplifier with high power if you like listening to your music at high volume levels.
