There are (of course) others who claim exactly the opposite, that enclosures are essential and that the open baffle idea is flawed. Some insist that any enclosure is bad, and the speaker drivers should be free, allowed to show their naughty bits to the world should anyone peek around the back. Open baffles create a dipole effect - the sound will be (generally) equally loud directly in front or behind the speakers, with (theoretically) zero output from the sides and top. The important thing to remember is that a properly designed speaker requires both the right enclosure and the right driver working together to create the right audio system for your application. Speak to your speaker designer and manufacturer about the solution that best balances and addresses your loudspeaker needs. You would need to manually calculate the dimensions based on the specifications of your subwoofer.
Subwoofers / Amplifiers
Many of the early 'tuned' boxes were what's now commonly referred to as 'boom boxes', because they had excessive and often 'one note' bass. Countless programs have been written to allow users to design an enclosure, based on the Thiele-Small parameters. This has removed much of the guesswork, but by themselves, the programs are (mostly) unable to provide a complete design.
Speaker Drivers
For example, plywood may be preferred for the outer surface, and MDF is then ideal for the second layer. If a slightly flexible adhesive is used between the two, they will be decoupled to some extent, which reduces the Q of any resonance that does exist. Tee-nuts or other metal threaded inserts can be placed between the two layers so the cutout for the woofer/ midrange drivers can be radiused on the inside. In general, the baffle should not be recessed to allow for a grille cloth or protective cover.

I (naturally) will make no recommendations one way or another, and there are so many conflicting opinions that I can only suggest that you do your homework, and decide for yourself which way you want to go. Braces should be made from rectangular hardwood (e.g. 50 × 25mm/ 2 × 1 inch), and always glued firmly in position with the short edge to your panel. Ideally, they will also be screwed (or nailed if you must) to ensure a firm bond while the glue sets.
Determiningthe port parameters for a cabinet is not complicated but it is best to use acalculator on the manufacturer’s website. Flared ports are not all the same and reaching the target tuningfrequency is easy to determine by plugging in the necessary parameters into themanufacturer’s website. Just note thatit is best to leave the port tubes a little long and trim to reach the targettuning frequency.

Every small aberration can be measured, but often it will not be audible in situ. You may hear a difference, but again, being different doesn't necessarily mean better. Despite the claims of some, measurements are far more revealing that our hearing ever will be, as hearing evolved primarily to keep us alive ... While making an enclosure with no parallel sides is possible, it's very difficult for the home constructor making only a pair of enclosures. The vast majority of speakers use conventional parallel sides, front and back, top and bottom.

Hereis a list of materials and tools needed to pull off a typical cabinet build. Type its dimensions and the program will calculate the approximately useful volume of the space. Do you want to fit the box in the space of the apartment, in the trunk of the car or choose a speaker for the existing box?

The optimizationprocess is applied to the low-pass, band-pass and high-pass filters and acombined response is generated. Due toresponse issues, it may be necessary to attenuate a target or move thecrossover frequency slightly to obtain a flatter response. Ultimately, it may take several rounds ofmoving crossover frequencies and even filter orders to get to an acceptablesystem response.

It's tempting to do so, but it can cause considerable disturbances due to diffraction. The speaker drivers should be recessed into the baffle though, so there are no discontinuities across the face of the baffle itself. For small 'near-field' speakers (as might be used with a computer for example) it probably doesn't matter, but I have been able to measure a small 'glitch' in the response of speakers that are surface mounted. Minimising discontinuities is almost always beneficial, but some will always remain because of the way most speakers are manufactured. Just the surround and cone of a midrange driver can create small but measurable response anomalies, but reality tells us that there's no much that can be done to avoid this.
Even dispersion does have some major benefits of course, especially if you listen (or are forced to listen) off-axis of the system. The so-called 'sweet spot' needs to be wide enough so that everyone listening hears the same (hopefully) well balanced sound. This is achieved in only a few designs, and for the high frequencies it generally means using a well designed horn or waveguide.
Many users use our service to rapidly design their boxes and save time to spend it on really important things. While these common mistakes can be challenging, partnering with an experienced loudspeaker manufacturer like MISCO ensures optimal results, thanks to their advanced expertise and tools. A theoretical infinite baffle will be large enough so that the soundwaves will never “reach around” to the back of the speaker.
Particle board (aka chipboard) is one material that was once used extensively by low-cost manufacturers and hobbyists. It is sub-optimal in almost all respects, and in particular the structural integrity is found wanting, so corner braces are almost always needed to the box doesn't disintegrate during handling. Particle board can be obtained with high-grade real wood veneer, and while this makes the finished item look better, it's still fairly low-strength. If a veneered finish is used, this pretty much eliminates the possibility of using radiused edges, so edge diffraction will be greater than desirable.
This may be true in some cases, and if this approach is aligned with your wants/ needs, then you have to be prepared to spend serious money for anything 'decent'. Ideally, your speaker will be a point source, so that all frequencies emanate from the same place in space. Tannoy has (for a long time) made speakers that are as close to a real point source as you're likely to find. Their coaxial speakers have a horn-loaded tweeter that's concentric with the woofer/ mid-bass, and it uses the main cone as part of the horn.
