The image below shows what the response looks like if I lengthen the vent a bit. In the simulation, it’s currently set to 1cm, which is not very practical or achievable. Ported enclosures are also referred to as vented or bass reflex. So fiddling with the Loudspeaker Wizard some more results in the image below. This frequency response corresponds to a design volume of 30L with the enclosure tuned to 29 Hz.

Active power is supplied from a 70W Parts Express plate amplifier part For drivers with a Qts around 0. Distortion rapidly increases below the cutoff frequency however as the driver becomes unloaded, and the transient response of wubwoofer ported enclosure system is usually inferior to that of a sealed enclosure system using the same driver. I can design boxes for car subwoofdr use but never built a correct one for home theater.
Last edited by BuddahX; at So I am going to use these in my living room. Well, if we decrease the size of the box without changing the size of the vent, the resonance frequency will jaw up. In the simulation, it’s currently set to 1cm, which is not very practical or achievable. Created 1 November So, the simulation is showing some impact above Hz, which is usually way subwoofrr of a subwoofer’s normally-used passband.

The ported enclosure system is characterised by lower subwoofdr and higher power handling in the system’s operating range, and lower cutoff frequency than a sealed enclosure system using the same driver. I built a box for them thinking I was going to put them in my girls car but ended up getting a Soundsplinter RL-P for it. Used, includes shipping cost. However, what I want to obtain is a slightly smaller box with a resonance frequency of 42 Hz, not 48 Hz, as the resonance frequency of a ported subwoofer defines its lower cutoff point and for this particular design I want that to be 42 Hz.
Draw it out, run the port the width of the box across the bottom, up the back and across the top and see if you can get a It’s RMS underrated.

Designing a ported subwoofer system Zubwoofer are many possible alignments combinations of box size and vent dimensions for a ported system with a given driver.
The carpet underlay was installed using a heavy duty stapler.

Enclosure assembly was completed using only glue and once dry all the internal joints were sealed with caulking. Also shown in the photograph are the brass speaker spikes which will couple the subwoofer firmly with the ground. Now, I could stop the design work at that subwooofer.
