Hej TC,
Jeg har også surfet en del efter info om, hvordan man stykker en Open Baffle sammen og er vist kommer frem at der ikke findes noget enkel udregningsmåde.
Selv regner jeg med at lave en plade på ca. 120 cm (højde) x 60 (70?) cm bred og sætte "vinger" på ca. sådan her:
Jeg vil lave mine med udskiftelig forstykke til enheden (der skal kun én fuldtoneenhed i mine), så jeg kan prøve flere slags højttalere af.
Hvis du vil, kan vi lave denne tråd om til en videnstråd om Open Baffle og samle info som denne bid:
"In case you're curious, the drivers in open baffles tend to be offset to avoid a huge hump at the frequency where the baffle dimensions match the wavelength. This is why you won't see good designers using square or circular baffles. Also, the baffle can be folded back upwards of 90 degrees to accomplish nearly the same extension as a flat panel. This allows for a larger baffle in a more WAF friendly package, but it also reduces the midbass hump purely flat designs tend to experience. It also limits the problem with open baffles where the edges where the front and back waves meet tend to act as phantom radiators messing up the response something awful. The last major issue with open baffle designs, other than their need to be quite large for low frequencies, is that they also require a quite large room for this same bass. Dipoles cannot pressurize a room like box or horn designs, so while the sound more naturally loads the room such speakers cannot benefit from room gain (typically 8-12dB/oct boost in lower frequencies depending upon the room's dimensions)." jf.
