    When choosing a 410 cab for a GK 800rb, would having a 4 ohm vs. 8 ohm 410 mbe ii make much difference?

    I bought an 8 ohm, 800 watt 410 mbe ii cab, thinking that the ohms wouldn't make much difference given the 800rb's reputation for not lacking power.

    Playing a show this weekend to hopefully answer this myself, but would returning the 8 ohm cab for the 4 ohm be worth the shipping cost?

    Thanks for opinions on this.

    I like 8 ohm cabs personally. Always gives you the chance to get another for bigger shows and more speakers = more volume.
     
  3. The amp probably does 400 or 500W on a heavy slam into 8 ohm so unlikely to gain much of any headroom before the 4 ohm would fart out anyway.

    I am not too familiar with the MBE cabs but I know I have and run a 1001 RB II through a Neo 410 and it gets plenty loud and I still have a lot of headroom. Those are 8 ohm cabs. Plus, as stated above, with an 8 ohm cab, theres more room to add another cab for bigger shows. You'd be bringing down the house with thunder!
     
  6. Keep the 8 ohm cab. You'll be able to add another 8 ohm cab down the road should you wish to do so. Perhaps another 410 or a 212. Rock on!

    You're pushing 200 watts into the 8ohm cab vs. 300 watts into a 4 ohm cab with that head. I used to run a 4ohm 2x12 with my 800RB with great results.

    As others have suggested, the 8 ohm cab allows for more flexibility and choices. The 800RB can drive one single 4 ohm cab, or up to three 8 ohm cabs (two from the 300 watt output, one from the 100 watt output). If you need more volume, two 8 ohm 4X10s will go further than a single 4 ohm 4X10 cab (obviously assuming the cabs are similar or identical in terms of sensitivity etc.).
     
  9. You wouldnt gain much (if even noticable) SPL switching to a 4 Ohm cab. You would gain a lot of SPL adding a second matching 410 should you need more volume.

    I don't think I'll ever be adding a second cab, so if it's not a noticeable difference in SPL, headroom, and overall performance, I guess I'll just stick with the 8 ohm.

    A few years ago I pushed an Ashdown ABM 410 with a GK 700rb - with good results, and the Ashdown is an 8 ohm cab.

    I'll crank it Friday and see how she does.

    Thanks everyone!

    Keep on bassin'
