Passive Radiator Bandpass Subwoofer

This is an Bandpass-Subwoofer. I made it, just in order to see if it is possible or not. It contains a 10cm Visaton Midrange Speaker and an Passive Radiator wich i made from a burned out 13 cm Speaker. Its Frequency Response is 35 to 90 Hertz. Cannot play very loud - but DEEP! :-)

[Dampfplauderer96]

kann ich bei nem passive radiator auch den ganzen korb abflexen?

[Elnufo]

@Dampfplauderer96 Oh nee, das würde ich nicht machen, wenn Du den Korb komplett entfernst, verlierst Du damit die Zentrierspinne. Ich habe das früher mal gemacht. Das Ding war danach nicht zu gebrauchen, denn ohne die Zentrierspinne taumelt die Membran zu sehr. Kann ich nicht empfehlen.

did you just pull the magnet off with a chisel/flat-head screwdriver, or something else? I wanted to make something similar.

Thanks

@trystanhardy You're right, that's just what i did. Be careful not to bend the upper rim/mounting edge of the speaker, it needs to be absolutely airtight. Orherwise it won't work properly. Maybe i will make some kind of "howto" video on this...we'll see.

I still like a slot port more then a passive radiator. I got 25 hz with a 6.5'' driver in a bandpass box. But I chanced the driver for a 8''. That made it much louder. That box sounds good though.

@Elnufo thanks for the reply. A how to video would be a good idea i think.

Thanks again

[SmallRoomBigSound]

I see. I'm gonna say it again, it sounds very very good, even over a Youtube video :-)

[Elnufo]

@SmallRoomBigSound The Speaker itself is unmodified, but i removed the magnet and added some weight to the voicecoil to get the desired frequency response.

[SmallRoomBigSound]

did you remove the magnet or modify the speaker to make it a PR?

[Elnufo]

@SmallRoomBigSound thank you, glad you like it :-)

[SmallRoomBigSound]

that sounds very very good!

Turn it up louder until the speaker starts moving, show off what it can do!
