To further explore the amp-speaker interface, recently purchased an Audiopax Maggiore100 to pair with Zu Defintions. Noticed the output impedance is a bit high at 2.5 Ohms. The speakers are nominally 8 Ohm but dip to 6 ohms in the bass region. It's been said the speakers are an easy load and 100 watts to power a 101db efficient speaker should result in considerable headroom. Question is will the somewhat high output impedance of the amp still affect the bass negatively?
Increase total Speaker Impedance -- Potential Solution
Hi All,
Years ago I asked about using a resistor to increase the total impedance of a speaker -- I know that's a bad idea now because Impedance is NOT the same as resistance. I did get a pair of Paul Speltz's Zeroformers and they are great!
However, reading more about this, I thought another, more cost effective solution. Why not just buy a low cost, 4 ohm speaker, remove the diaphragm inside, and series-wire it? I'm reading some of the Zeroformer's technical documents and it sounds like it's rather similar to a speaker coil that doesn't produce any sound. Therefore, if I just series-wire a 4 ohm speaker to my existing 2 ohm speaker, wouldn't the total ohm seen by the amp be 6 ohm?
