    So, since there are no gigs (or anything) I brought in my 15s. I plugged one into the output then plugged the other one into that, daisy chained? Then the 810 as usual and switched to 2 ohm. The 15s are so much louder I didn't think the 10s were on. Why? The 15s are both 8ohm. So chained together that's 4 ohm same as the 10s. Curious as to why. Thanks. 20200330_191905.jpg

    And yes, I was playing my guitar through it. I run the little digitech pedal into the svt with the gain down, instant killer tube amp! Switch the cord, crank gain, drop vol and play bass.

    Have you checked your 810 for damage? If it's a 2 x 410 sections cabinet, are both sections working?

    They are. There's nothing wrong with it.

    How much is way different?

    Is it possible that your cabinet got "rewired" by somebody who didn't know what they were doing and thought that the internet was always right? Happens all the freekin' time, deal with this regularly when troubleshooting with customers.

    Try the battery test on the cabinet and make sure all drivers move the same direction.

    Did some checking, experimenting. Turns out the ohm switch wasn't fully into 2ohm but its is still louder. All drivers are working. Cab is the E and its mint.

    The 15s are alot brighter and thinner sounding. They don't sound bad or anything but the 810 sounds alot thicker and deeper than the 2 15s. It's like a different eq. I use the for lows only in a biamped Rig. Adds low end vibration to the stage so I don't run as much bass from my 4 pro live. These are new cabs. Never opened nor damaged

    All this was with a guitar. Tomorrow I'll experiment using a bass.

    Sorry, typo. It should have read "battery test".

    But possibly mis-wired or defective.

    Try the battery test on each cabinet, the drivers should all move outward when the + terminal is connected to the tip and the - terminal is connected to the sleeve. Test each cabinet.
     
  11. You're already playing through a tube amp. That's what SVT's are.

    Put a Auralex GreatGRAMMA v2 Isolation Riser under your cab and it will kill the stage vibration as well as reduce some of the muddiness and give you more clarity.

  12. "Perceived" loudness. It's most likely the frequencies are being thrown differently. The way I hear (most) 15" cabs are very high and high mid apparent. Not lows. Yeah, lows are always there...it's a bass. But, the higher end of the spectrum is most likely what's hitting your ears. Where as, your 810 is throwing more lows and low mids at your face. More oomph, more presence, less "perceived" volume. Its much louder. You just dont realize it.

    The 15s are there
    I swear I don't speak English. Obviously it's a tube amp. My point was. Through a guitar pedal in front and I now have a tube guitar amp.

  15. Put one under the 15's as well. :thumbsup:

    Gotcha. ;) Maybe it was my interpretation. :D

    Then it must be the combination of sensitivities and voicing of the cabinets.

    I find 10's will sound 'scooped' for a guitar whereas 15's will be more mid forward, with bass cabs at least.
    And with the sensitivities of the human ear, might explain what you're hearing.
     
  19. Size of speaker has nothing inherently to do with the tone of the speaker... it's just the design of each individual speaker that decides it's unique tone. 10s can be mid heavy or have deep bass or be full range... same with 15s... or either can be scooped....

    As the old saying goes.....

    Size doesn't matter (regarding tone, at least).

    Although, it actually can matter since a larger speaker will be louder (more efficient) given exactly the same specs of everything else about the speaker.
