i am sorry its an IDQ15d4v2 it says it should be a good fit but what is it tuned to?

 

[mazdakid 5,000+ posts]

i get somewhere around 45hz

 

[budahbuddy803 10+ year member]

is that too high?

 

[mazdakid 5,000+ posts]

yes thats too high for daily driving, especially with that sub

ok the deminsions are, 21" long, 18" deep, 16.25" tall for the box which should be 2.72ft^3. The port is 14.75" long and is 41.32"^3. It is made out of 5/8" MDF.

What about a 1.5ft^3 sealed box? and yes it will be a single sub setup for now. My amp will put out 800RMs i was thinking about pushing 700rms to this sub.

i know, and i got about 45hz out of that

a sealed box will sound better than a ported box at 45hz

get a box tuned to about 38-40hz...not a huge difference..

 

[mazdakid 5,000+ posts]

id get a box tuned no higher than 35hz

with this sub... should i go sealed prolly 1.5ft^3 or should i go with 2.5ft^3 tuned to 32hz? Which would preform better SQL wize?
