Toyota Tundra blow thru box suggestions?

[Joe X]

Went for a 2.5:1 to save some space, 2 cubic feet per driver for the rear chamber:

 

projected frequency response:

 

Cone displacement:

 

Vent airspeed:

 

TOTAL BOX SPECS:  4, 10@45Hz  240 SQIn of port area.

 

Bear in mind that this type of enclosure needs strong midbass drivers on your front stage, it is not like ported.

 

Also the port must be removable so that you are able to re tune if necessary.

 

Finally the sundown design is set for maximum output so if you are into sound quality you may not be impressed.

thanks for all the help. I already bought the subs so im stuck with them lol. would it be better to just cut more of the bed and cab and just build a regular ported box and forget about the 4th order?

[Joe X]

It would be a very large cut, I wouldn't try that myself. The BP4 can be made to work is just that it will take some extra effort and time, check out the builds on here and elsewhere, usually takes months and a lot of money to build and dial in a good system.

I've competed before both in IASCA SQ and DB drag (probably showing my age lol) so i know it's not cheap or quick. just never done a 4th order.

You can delete your rear seats and do ported, no actual need for a blowthrough, or you can also get someone to do the job for you, who has measurement instrumentation, there are always options.
