This is for playing under the mix with low B, long extended notes like in Slipknot. I currently play through a Mesa M6 + Powerhouse 4x10 current triport version. Anoter 410 or going the 810 is the real way to go but currently I can not transport that. Would the Schroeder 1515L be up to this kind of punishment with the M6 ? Would I have to push it too hard to get the volume I need as one driver is not forward facing ? I guess it would have to be raised from the floor so it at least fires at knee level like a 410, otherwise with it on the floor I would have to turn it up even more. Or should I only consider the larger 1515. With Markbass I would be adding the 151NY extension cabinet or the 15inch traveller. However, I would be missing the tone of the M6. This would be very expensive. The NV412 sits at the right level on it's own, harder to transport than the 1515L.
