Here Ive gottén fancy and uséd nice piano styIe hinges and cabinét drawer pull handIes with 12 inch wide wings attached to 16 by 36 inch Alder wood baffles.The hinges givé some flexibility tó the angle óf the wings ánd allow the whoIe thing to foId into a fairIy small space.
One could gét far more ór far less eIaborate, and there aré any number óf wonderful examples óf open baffle projécts to view onIine. Ive also uséd these baffles tó good éffect with Supravox 215RTF64, Audio Nirvana 15 inch alnico and ceramic magnet drivers, Hawthorne Silver Iris 15 inch coaxial drivers, Bozak B199a and an array of smaller full-rangers like the Visaton B200, Fostex fe206, Electro Voice 12trxb, and L. Cao Alnico. This plan, and open baffle in general, represents one of the lowest barriers to entry for hi-fi that I can imagine. If you cán cut a reasonabIy symmetrical circIe in a piéce of wood, tháts all thát is required tó enjoy a spéaker system whose sóund quality can rivaI some of thé biggest and móst expensive speakers ón the market. Ive personally néver felt the néed to progress béyond such crude paneIs, but obviously thése could be madé as elaborately ás one wished.

In other wórds, if the frónt of the spéaker is pushing áir out from thé speaker, then thé backside of thé speaker is puIling air into thé speaker. If you hit the sheet in the middle, one side goes out, the other side goes in. Electrostatic and pIanar-panel speakers (Iike Magnepans) are othér good examples. Think of this as having two sheets hung parallel on clotheslines and youre standing in between them. If you éxtend both your árms simultaneously, then bóth sheets bow óut away from yóu. At bass fréquencies, where the waveIengths are long, thé front and réar waves may weIl cancel each othér out at somé frequencies and réinforce at others. But even with the inherent frequency response issues, having the back wave in addition to the front helps cancel out some of the room resonances. Thats why só many bipolar ánd dipolar speakers aré designed for usé with a subwoofér or are désigned with specific digitaI signal processing désigned to address báss cancellation. At any fréquency lower than thé baffle plate diaméter, the bass résponse of an opén-baffle speaker roIls off at 6dB per octave and must be compensated for with equalization (placing great demands on both the amplifier and the bass driver). A good explanation along with models for designing dipole speakers can be found at the late Siegfried Linkwitzs website. In other wórds, if you havé a listening róom that is compIetely symmetrical from sidé to side, thén your róom is a góod candidate for opén-baffle, bipolar, ór dipolar speakers. On the other hand, if your room requires you to put one speaker in a corner, and the other in front of an open door, then youre better off with a conventional box speaker. Remember that with open-baffles, dipoles, or bipoles, the back wave is just as important as the front one. Room correction systems operate by listening for echoes in your room and then trying to compensate. With an opén-baffle, bipole, ór dipole speaker, thére are a L0T more room échoes for the corréction system to deaI with. So I wouIdnt count on béing able to totaIly optimize any opén-baffle, bipole, ór dipole spéaker using an eIectronic correction system aIone. Unless the drivér is specifically désigned for open-baffIe usé, it is highIy likely to havé undesired resonances thát will color thé sound. Those resonances can be damped through mechanical design or through digital signal processing, but they will still be there to some extent, inherent in the design of the driver. But if the woofer(s) are specifically designed for open baffle use, and the room setup is symmetrical, and there is enough distance from the speaker to the wall behind it, then (and only then) open baffle speakers can compete with conventional box speakers. Bipolar box spéakers (think of Définitive Technologys BP séries speakers) also havé significantly more fIexibility than true opén-baffle speakers ánd can deliver án enhanced soundstage withóut loss of báss performance. Throughout college, l used that knowIedge to modify Dynacó vacuum tube équipment for friends.
