    Curtwash2, Here is the info you request. Version 1: Polar response curves Version 2: Polar plot If you consider -6dB to restrict the beamwidth SPL loss, then I would summarize the dispersion: ~120° @ 1,500Hz ~90° @ 3,000Hz ~80° @ 7,000Hz ~55° @ 12,000Hz ~30° @ 16,000Hz ~20° @ 20,000Hz...

    For Sale ► Hygeia Electron Co. Air Motion Transformer (AMT) & Planar Magnetic Ribbon Tweeters ◄

    Curtwash2, Everything is brand new from my receipt of this order in July of this year. Only opened boxes to inspect them for damage and to measure frequency response and distortion with my Dayton Omnimic V2. To be perfectly clear: extra diaphragms are not free. They can be purchased by...

    I haven't measured the horizontal dispersion for it, but I get a few measurements and report back.

    yup you have it right about roll off. If the response has "rolled off", means that the output has dropped, just like the height of something that has rolled down a hill---if it rolls down, it is now obviously not as high as before. A speaker that has little to no rolloff as the frequencies get...

    1x18 Cabinet

    So it looks like you know what you want in terms of sound. So are you going to look at cabinets to purchase, or are you going to try and learn the DIY route?

    1x18 Cabinet

    I retract the statement about that power level. I figured the fundamental coming in much stronger than it really does. Since it's power density is only a fraction of the 2nd harmonic, it's gonna be much easier than I originally thought, since ~45Hz response is an (almost, lol)...

    I like your style. I am a Cerwin Vega "enthusiast" with several of their subwoofers I plan to make use of. I also made some folded horns with my dad in the 90's with some Fane 15"/18" drivers that still work to this day. Oh and by the way, you mean "mouth" not "throat aimed towards tables.."...
