TYPICAL · 30 BASS CABINETS from Darwin's Cat Made with Orbit Bass Cab Builder 0.4.0. A click on one opens it on the page. The line: the cabinet's response at 48 kHz, levelled to its own 100 Hz to 5 kHz. Green is fine; red falls 3 dB or more into a pit, or the two mics cancel there. The bands, with two mics: where they meet. Green, they add up; red, they cancel. The stronger the colour, the deeper, full at 6 dB. 4x10 CLOSED HORN -6 · MD421+U47 4x10 · CLOSED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 4x10 CLOSED NO HORN · MD421+U47 4x10 · CLOSED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 4x10 PORTED HORN -6 · MD421+U47 4x10 · PORTED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 4x10 PORTED NO HORN · MD421+U47 4x10 · PORTED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 4x10 OPEN NO HORN · MD421+U47 4x10 · OPEN · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 8x10 CLOSED NO HORN · MD421+U47 8x10 · CLOSED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 8x10 CLOSED HORN -6 · MD421+U47 8x10 · CLOSED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 8x10 PORTED HORN -6 · MD421+U47 8x10 · PORTED · HORN -6 dB · MD421 50% + U47 50% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 6x10 PORTED HORN -6 · MD421+U47 6x10 · PORTED · HORN -6 dB · MD421 50% + U47 50% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 6x10 CLOSED NO HORN · MD421+U47 6x10 · CLOSED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 6x10 CLOSED HORN -6 · MD421+U47 6x10 · CLOSED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x10 CLOSED NO HORN · MD421+U47 2x10 · CLOSED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x10 CLOSED HORN -6 · MD421+U47 2x10 · CLOSED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x10 PORTED HORN -6 · MD421+U47 2x10 · PORTED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x10 PORTED NO HORN · MD421+U47 2x10 · PORTED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 1x15 PORTED NO HORN · MD421+U47 1x15 · PORTED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 1x15 PORTED HORN -6 · MD421+U47 1x15 · PORTED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 1x15 CLOSED HORN -6 · MD421+U47 1x15 · CLOSED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 1x12 PORTED HORN -6 · MD421+U47 1x12 · PORTED · HORN -6 dB · MD421 50% + U47 50% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 1x12 PORTED NO HORN · MD421+U47 1x12 · PORTED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 1x12 CLOSED HORN -6 · MD421+U47 1x12 · CLOSED · HORN -6 dB · MD421 50% + U47 50% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 1x12 OPEN NO HORN · MD421+U47 1x12 · OPEN · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x12 PORTED HORN -6 · MD421+U47 2x12 · PORTED · HORN -6 dB · MD421 80% + U47 20% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x12 PORTED NO HORN · MD421+U47 2x12 · PORTED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x12 CLOSED HORN -6 · MD421+U47 2x12 · CLOSED · HORN -6 dB · MD421 80% + U47 20% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x12 CLOSED NO HORN · MD421+U47 2x12 · CLOSED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x15 PORTED HORN -6 · MD421+U47 2x15 · PORTED · HORN -6 dB · MD421 50% + U47 50% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 2x15 PORTED NO HORN · MD421+U47 2x15 · PORTED · NO HORN · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 4x6 PORTED HORN -6 · MD421+U47 4x6 · PORTED · HORN -6 dB · MD421 65% + U47 35% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30 8x8 PORTED HORN -6 · MD421+U47 8x8 · PORTED · HORN -6 dB · MD421 50% + U47 50% 50 100 200 500 1k 2k 5k 10k +10 0 -10 -20 -30
