I built a box for them thinking I was going to put them in my girls car but ended ma getting a Soundsplinter RL-P for it.

The carpet underlay was installed using a heavy duty stapler. The interior of such enclosures are often lined with a damping material to damp the resonance and absorb the midrange from the rear of the driver diaphragm.

The response is not as flat as the previous iteration of the design, but the target resonance frequency has been obtained and the passband is smooth. To fill in the bottom end of my Sealed Bipole with Fostex FEEI decided to design and build a small subwoofer which would mate up with these fantastic sounding fullrange speakers.

To make the subwoofer more versatile, the driver is connected to a switch which allows the ability to switch between the plate amplifier or binding posts for use with an external amplifier. Help Designing a box for two MAW The image below shows what the response looks like if I lengthen the vent a bit. Thank you for any help that is provided.

It’s RMS underrated. Draw it out, run the port the width of the box across subwoover bottom, up the back and across the top and see if you can get a Designing a ported subwoofer system There are many possible alignments combinations of box size and vent subwoofwr for a ported system with a given driver.

To make the subwoofer more flexible, it houses a 70W plate amplifier, but can also be powered with an external amplifier. Binding Posts and Switch for External Amplifier.

A picture of the driver is shown below in Photograph The driver can easily soak up all the power that the small plate amplifier can deliver. Last update 12 July So I am going to use these in my living room.

For a nice flush finish the driver is countersunk into the baffle as shown in Photograph Created 1 November The driver has a rubber surround and houses a 2 inch voice coil with vented pole piece, wrapped mwa a 2.

Subwooder cast frame is thick and the total weight of the driver is 6. For the best viewing experience please update your browser to Google Chrome. These can be reduced in level by lining the box with acoustic fiberfill.

Rather than use a pipe for the reflex port, the enclosure is vented using two square ports 1. The ported enclosure system is characterised by lower distortion and higher power handling in the system’s skbwoofer range, and lower cutoff frequency than a sealed enclosure system using the same driver.



The subwoofer performs very well, producing nice tight ,aw. Anybody have any suggestions on what type of tuning and box design for these thank you for your time. Now, let’s use the Loudpeaker Wizard, and adjust the length of the vent, Lpt, until Hornresp tells me that the resonance frequency is 39 Hz, the same as the driver’s Fs.

You currently have 0 signatures. So, the simulation is showing some impact above Hz, which is usually way out of a subwoofer’s normally-used passband.

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.
