Question re: Ohms, Amp heads & mixing & matching
« on: May 18, 2017, 03:13:42 PM »
Hi,
    There is a guy selling two Eden 210xst and both are 4ohms.  After doing some research and deliberation on the best combinations it seems to me that getting two Eden 210 xst cabinets would be a better idea for me. According to the specs I should be able to get a lower frequency response this way than  I would with a 410xst cabinet.

I believe that the 210xst are 500watts each. The 410xst is 1000watts.
Question
1)  What eden amp heads old or new can power these 2 four ohm cabinets at the same time?
2) Using two 4 ohms doesn't that mean it is in need of a 2 ohm amp head?
3)  Is there a Y speaker cable splitter or something I can plug into one of the jacks in my 4ohm amp head to make it able to use one 4ohm 210xst. To make the amp think think it is powering 4 ohms through two 8 ohm jacks? I have a combo that only takes two 8 ohm cabinets in two different jacks to max itself out. 

From everything I have read I can't plug a 4ohm into it.  Looking for ways around this if possible.  The deal on the 210xst 4 seems so great.  but I only have what appears to be a wt300 head in a cxc 300 solo series.

Thanks,
Ian

From what I remember, your CXC300 is a single channel amp, capable of putting out 300 watts into a 4 ohm load, and 175 watts into an 8 ohm load.


You can only connect a single 4 ohm cab to the amp. Two 4 ohm cabs would result in a 2 ohm load and potentially overheat and destroy your amp.
You could connect a 4 ohm 410XST to your cab and drive it with the full 300 watts.
You could connect a single 210XST to your cab and drive it with the full 300 watts. 




There are quite a number of Eden dual channel amps that could drive both of the  4 ohm 210XSTs at the same time.  The early WT800/WT600/WT500 series are all dual channel, and capable of driving a 4 ohm cab on each channel.  The WT800 would probably be the best match, as the early versions produced 400 watts per side into a 4 ohm load.


The later WT800C model(+/- 2006) put out 440 watts into a 4 ohm load.

Hi
That is what I  was hoping  to hear.
I will probably buy one 210xst 4ohm cabinet.
Just unplug the cable from the attached cabinets  212s.
This will be somewhat versatile sound wise in my music studio.

The manual says never plug anything but 8ohms into the head. Thus I was unsure about the 4ohm.

Now I  can't  wait to buy and try this out.
Cheers
Ian

if you plug a 4 ohm 210XST into your CXC300 you will need to disconnect the internal speakers.  Reason for that is that the internal speakers are 8 ohm and if you plug in a 4 ohm speaker in addition to that, it will drop the ohms load to 2.67 ohms which is below the 4 ohm minimum load. That will overheat and can smoke your amp if the protection circuits don't stop it in time. 

Adding an 8 ohm speaker to your CXC300 combo would drop the ohms load to 4 ohms total and your amp would put out the most it has to give into those two cabs.  That's why it says to ONLY plug in an 8 ohm cabinet.

Again, you CAN NOT plug in a 4 ohm cab to your CXC300 unless you disconnect the internal 212 speakers or you may damage your amp.

Be very careful to unhook the internal speakers BEFORE you plug in any 4 ohm cab.

Sorry, forgot to mention that very important point!  :-[
