The loudspeakers for life

We manufacture revolutionary and unique High-End speakers, 

that you can buy directly from factory in Poland.

High-End high frequencies adjustment to fine tune your system

The IQ speakers are very neutral. The crossovers are perfectly matched, but we want you to be able to match them perfectly to any room and system.

That's why we decided to equip the speakers with an additional pair of WBT terminals on the back, which connects only to the Mundorf AMT dipole super tweeter.

You can connect various Mundorf copper-nickel resistors to these terminals. The resistors are color coded so you can easily connect them to the speakers. 2 resistor values are available in the standard package and 5 values are available in the precision package.

All resistors are soldered with gold plated copper banana plugs, so you can change them in seconds and adjust the amount of high frequencies to your taste.
