Some time ago last year a speaker building buddy of mine in California decided to see what he could do in a simple, inexpensive, open baffle project. He came up with a 2 way passive system on a medium size baffle. He has been trotting them out at shows across the country and baffling a lot of folks who would never have thought so simple a concept could sound so good.
For your pleasure, here are the build specs on the Manzanita 12s
What were some of your goals with the design of the speakers
? In the end, did you achieve them? If not, where did the design fall short of your expectations?
examples: I wanted to create a speaker with perfect tonality but ended up with something that sounded like it plays under water.
|Freq Range||<eg -6dB at 27Hz and 33kHz>|
|Freq Response||<eg 34Hz – 28kHz ±3dB on reference axis>|
|Dispersion||<eg - Within 6db of reference response>|
|Horizontal||<eg - 60 degree arc>|
|Vertical||<eg - 10 degree arc>|
|Sensitivity||<eg - 90dB spl (2.80v, 1m)>|
|Harmonic Distortion||%THD or plot|
|Nominal Impedance||<eg - 8 Ohm, min 2Ohms>|
|Crossover Points||<eg - 300Hz, 4KHz>|
|Power Handling||<eg 50-250W>|
|Dimensions||<eg - 60x12x16 in (HxWxD) >|
|Approx Weight||<eg - 40kg (88 lbs)>|
|Recommended Materials||<eg - MDF, Birch Ply>|
