Stick with 8 ohm cabinets always. Again, this is where you will recognize significant coverage differences because you can always add more 8 ohm cabinets than you can 4 ohm cabinets. Simply put: 2 - 8 ohm cabinets running parallel is a 4 ohm load and will pull whatever the 4 ohm indicated output level of the amp is, BUT, because you have more speakers, you'll recognize significant volume coverage. BTW the difference you hear between 1 4-ohm cabinet and 1 8-ohm cabinet individually running from the same amp is nominal. AB it and see for yourself. Another case for sticking with 8 ohm cabinets. The best way for you to hear this put to the test is do this: Scenario 1: Hook up a quality 4-ohm cabinet (ex. 1 210XST(4)) to the amp (assuming the amp can handle a 4-ohm load). Then play and listen. Scenario 2: Hook up 2 quality 8-ohm cabinets (ex. 2 210XST(8)'s) to the same amp. Then play and listen. You WILL hear the difference from Scenario 1 above and realize a significant increase in coverage. NOTE: Under Scenario 2 and if the amp can handle a 2 ohm load, you can still add 2 more 8 ohm cabinets for even more coverage!!! If you haven't heard this, you must try it one time in your life. : ) Granted, you may not need the additional coverage, but WHY limit yourself???

I really, really appreciate that response! I've had my SWR Goliath III for a long while. When I first acquired my Eden Traveler Plus, I used it to power my SWR for quite a while (sounded great to me!). I was speaking to a sales guy when I bought the Shuttle, informing him I had the SWR. He told me that, at about 350-400 watts feeding into the SWR from the Eden, it was a wonder I hadn't damaged my SWR a long time ago, as I was under-powering the cab. He said the Goliath III needed a minimum of 600 watts to run efficiently. I was a little shaken after that conversation, as I did not want to "tear up" my Goliath! However, as I mentioned before, I had apparently been "under-powering" my Goliath for a long while (according to the sales guy), with no obvious adverse effects at all. I started running the SWR Golith III (8 ohms) with my Genz Benz Shuttle 6.0 & 210 GB cab (8 ohms) at church three weeks ago (the Shuttle pumps 600 watts at 4 ohms). All I can say is, it sounds great and, so far, so good! |

What you really need to try is adding another 8 ohm cabinet. Most cabinets are wired parallel, so, all you would need to do is run out of one cabinet into the other. Remember, connecting 2 8 ohm cabinets to your amp will increase the load to 4 ohms. Provided your amp can handle a 4 ohm load, you won't have any issues. You will hear a huge difference in output and have all the coverage you will most likely need. Try it and see. Also....... You can NEVER have TOO MUCH headroom. My PLX-3602 will put out 3600W ![]() ![]() ![]() ![]()
