These boxes are more finicky to design – and aren’t too hard to get “wrong” (thin bass, boomy bass, etc.). “Ported” boxes utilize a tuned port to enhance bass response (aka bass reflex, vented, etc.). It works similarly to other online closed box calculators – such as this one:

SpeakerGen uses some simple math to estimate what box size a given driver needs to obtain a certain Q value – and what F3 frequency that will result in. Larger Q values still (say 1.4) result in a further loss in low-end response – but also introduce an upper-bass response peak – which can result in a boomy sound. That said – accepting a larger Q value (say 0.9) allows of a significantly smaller box – with only some loss in bass response. The Q of a box decreases as its size goes up – and vice versa.Ī Q of 0.7 provides the lowest possible F3 value – and by that argument is the optimal value for sealed speaker design. The Q of a sealed enclosure system will always be larger than its driver’s Qts. Sealed box speakers commonly have Q values in the 0.7 to 1.4 range. A speaker driver that sounds good in a 1.0 liter sealed box probably sounds pretty decent in a 1.25 liter sealed box.Ī sealed box / driver system is acoustically described using a number of parameters – an important one being “Q.” A box’s Q describes behavior around its resonance frequency – and hence helps dictate F3 value (bass frequency with a 3db drop in response). Sealed boxes are the simplest to design with primarily one variable: size. Notes on loudspeaker design / printing Sealed Boxes I can only speculate how boxes made with materials like rubber, wood, nylon or bronze would perform. So far I’ve only printed in enclosures in PLA. If your speaker doesn’t seem solid enough – just reprint with a higher infill percent! Assembly is almost instant – and printed enclosures intrinsically don’t have issues with panel fit. While printing speaker boxes is slow – and only really an option for smaller enclosures – it has several advantages. You can use these parameters to help determine what kind of box will work well for your speakers. Speaker drivers’ acoustic properties are described using “Thiele/Small” parameters (Qts, Fs and Vas). SpeakerGen provides a built-in tool that can automatically create an optimized sealed box for your driver’s parameters.
