An example of TL vs BR ?

[Booger weldz]

i snatched up the resent recommended venTed box for a rockford fosgate 12” p3…. It just so happened to fit in the HR suggestion/thumb rule for port tuning/length/hopefully incompressible mass/shape?

kinda funky high tuned car audio junk but it fit the bill.

any suggestions on what to look at ?

Not following the nature of the inquiry (yet). Need more.

As far as I can see:
A BR is a simplified vented design where it is normal to ignore some crucial detail during the design process.
A TL can be a PROPERLY designed BR, or something completely different.

Yeah, I was confused by the very high tuned and peaky box design. (Car audio is strange) ?

The same box volume made for a very awkward generic TL as well

Yeah, the mobile audio crowd typically want/need a 'one note' sub, which is in most cases is the correct alignment in general, but often not properly designed for the vehicle, i.e. a few generic alignments for the different vehicle model sizes.

Not this mobile audio guy.

What is the frequency response of a sealed and a ported kick drum in a standard drum kit???

Try the OD function. That Schematic Diagram does not look realistic.

It was just a generic TL sim using the exact same volume and tuning. Apples to apples.


I used a much larger tapered 1/3 offset TL for this driver tuned @ 28 hz. I thought the manufacturers spec vented design was awkward?


I dunno what the freq response is of a sealed or vented kick drum ?
