That will mean cutting the passenger side highs by so much, you may as well have no highs. Not to mention severely screwing up any kind of soundstage for a passenger seat rider.
Wouldnt polyfill help correct some of the backwave issues or lining the back cap with something rigid or even use deadener?that sphere idea fails when you don't have adequate airspace to play as low as you want. small full range is doable if you are on-axis and don't want a lot of volume.
airspace is crucial for midrange, as is the cavity. the last thing you want is a speaker in the middle of a sphere - backwave reflections should be directed away from the cone - not focused on it. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
nope. you need diffusion to break up back waves - and in order to be effective, teh diffusion needs to be 1/4 wavelength. think about what that means at 500Hz. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifWouldnt polyfill help correct some of the backwave issues or lining the back cap with something rigid or even use deadener?
Not misunderstood or ignored. Beaming can/will happen with anything larger than a 1/2" dome tweeter. How off axis a driver is affect this as well as material so its almost impossible to predict. It also only matters if your sitting outside the beam area. If your within the beam frequencies wont be lost to the ear. You only lose those frequencies outside the beam. Im sure in a tiny car like mine its difficult to miss the beam, but obviously not impossible.What was mentioned in the thread more than once, and what seems to be misunderstood or ignored by you(whitedragon551) is beaming. Beaming makes the frequency response of a driver worse off axis past a certain frequency dependent on the diameter of the driver. Please define/explain "beaming" - DIYMA.com - Scientific Car Audio - Truth in Sound Quality
Great off axis response depends on playing a driver below the frequency at which it begins to beam, among other things. Using 13,740/s (speed of sound in inches at sea level) / driver diameter in inches, a 2" driver begins to beam at 6,870 Hz. A 3" driver begins to beam at 4,580 Hz. I'm still trying to wrap my head around a lot of audio concepts, but hopefully this is helpful.
