One of the woofers blew out. Where can I get a replacement?

In a word, YES! The HK is designed for a minimum 4 ohm load. You can wire (2) 2 ohm speakers IN SERIES to get a 4 ohm load. Do NOT run one of them at 2 ohms as it will overload and damage your amp. Too nice an amp to abuse it like that...

I assume you mean the Pr-12RX passive? That seems wrong to me, too. Put an ohm meter across the terminals of the horn driver and the woofer seperatly to see which, if either, is blown. If they're OK, look for a bad solder joint on the crossover.

Please contact by mail describe haw many oHm of subwoofer, active or passive it? may be we can help w/ replacement subwoofer sunrisenohchi@ hotmail.com

contact maplin electronics they are really good at replacement units.

Yes. Contact CV for a replacement. Alternately, if you have a speaker refurbisher in your area, you can have them rebuild the one you have. There are only a few refurbishers/rebuilders in the US, so good luck.

You have damaged the power supply unit and this would have caused some failures on the power supply and sometimes on the drivers.
So first of all please check the power supply unit, alternatively the DC power required can be supplied by incorporating a new power supply with the same rating but working on 220volt.
repairing the 110 volt supply is no good as you will need again a step down to work , so I suggest this change.

Your woofer is bad, probraly blew the megnatic coils, and if mention that it's giving you a tearing sound, then the woofer cone is tear somewhere and is not get the reflex to produce the sound.

The voice coil of your woofer is off centered and shorting on the armture causing the speaker to draw too much current. The fuse blew thereby protecting the output stages of your amp. Replace the speaker.

Really does not matter the point is you can rebuild the woofer for less then replacing with a new one but to each his own on this. But as long as its the same size anything would do for this monitor speaker.

I do not mean to sound generic but its true a woofer is a woofer it is what it is sure there are brands out there but they all work basically the same.

All your doing is buying the name.

Check output transistors-most likely cause! also check for burnt resistors...
