The other part of the reality was that “plastic stuff” in the old days did not fit in with a boutique audio retailer’s ambience. Today, tooling is done on computer numerical control (CNC) machines directly from the 3D CAD in China, from very efficient specialists and the costs are reasonable. The days of the US union machine shop and hand work tooling on a lathe are history. Now consumer audio electronics are mainstream and global, and the quantities are huge. There were various reasons - one being that at the time, plastic tooling costs for serious audio products could not be amortized by the product sales numbers.

Plastic construction was for kids’ toys, walkie-talkies, and portable “transistor” radios, but not for music reproduction. How can you blame the customer for assuming little thought was spent on engineering if the exterior appearance gives this impression?īack in the 1970s, you could walk into an audio specialist retailer and not find a single audio product with a plastic enclosure, at least not with a speaker built into it. The flat baffle with the woofer and tweeter directly mounted in the same plane means the acoustic centers are most likely not aligned, and perhaps most importantly, your box will look just like the other models on the sales floor. The sharp baffle edges diffract sound where it is not wanted. Photo 1: Most bookshelf and larger boxes are simply medium-density fiberboard (MDF) that is vinyl wrap-covered and “groove folded” out of a larger sheet.īut wood boxes have their limitations. MDF just does not lend itself to thin unobtrusive soundbars, let alone smart speakers or in-wall speakers. Most of us acknowledge that the typical MDF has good acoustical qualities, but curved and shaped parts with this type of construction add greatly to the cost, along with the weight and bulk of MDF thick-wall construction. Conventional particleboard boxes are inexpensive, readily available, and a known commodity. A bead of glue is dispensed into the V-groove and the enclosure is miter-folded into a box shape. The grove-folding process cuts a V-groove into the wood, down to, but not through, the vinyl covering. Most bookshelf and larger boxes are simply medium-density fiberboard (MDF) that is vinyl wrap-covered and “groove folded” out of a larger sheet (see Photo 1). Other materials have been tried with limited acceptance but that has begun to change in a big way and is the focus of this article. Wood and wood particle board cabinets are traditionally used for mid-to-large-size speaker enclosures.

Enclosures also need to provide a rigid structure to support the drivers with minimum panel resonances. This is needed to avoid the front and back radiation from the cone from canceling each other. At the most basic acoustic level, the speaker enclosure’s purpose is to isolate the woofer’s back wave from the front.

To display diagrams you must fill in all appropiate fields (zeros disables the curves).No matter how much effort is spent on the loudspeaker driver design, the enclosure characteristics are still a significant factor in achieving smooth response, controlled bass, and defined stereo image. You are also able to calculate a Closed-Box if you make the value of the vent diameter very small (i.e 0.01).Īttention: You can put in your own Thiele/Small-parameter only if the speaker-select "parameterinput" is selected.

The colors of the curves in the diagrams for frequency response, step response, group delay and voice-coil impedance have the following meaning: On this page you are able to calculate a speaker enclosure with Thiele/Small parameter.
