Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker?


Anyone with a Class D amp play a 4 ohm speaker that dipped to 2 ohms.

I have a pair of Infinity Kappa 9 speakers that are nominal 4 ohm speakers that sometimes drop to 2 or 1 ohms.

Anyone here with a class D amp play speakers that dip down to ohms this low?

Really depends, but most Class D amps do pretty well with these. Hypex nCore is especially well suited to low impedance loads.

Can you say RUNNING TOO HOT! It may seem like a good idea but in the end the amp will run too hot and if played this way overtime will burn up. Infinity speakers are known for tearing up amps that are incapable of dealing with the impedance swings. I would try something more like a good mosfet design, like a ADCOM 555, or even better 2 of them bridged!

One of our past Audiogoners had class D Icepower amp (H2O), rated 2 ohm min, driving 1 ohm nominal Apogee Scintilla speakers with great results.
Anyone have experience running them with Quad electrostatics, which go down to 2 ohms in the high frequencies.  Considering for a pair of stacked quads.
