what size box for best performance?

[jrobie79]

i got 2 MTV thunder 4000 subs 10" whats the best size to build an enclosure so i get the best sound.

I cant be much help, but from what i have read on here the size of the box is in direct relation to a specific rating of the sub. Which rating it is however i couldnt tell you.

First place i would start would be to figure out which model i had.

Model Description Imped. Frequency Response Power Handling(RMS/Total) Sensitivity Voice Coil Magnet Weight Mounting Depth

T4104 10" Subwoofer 4 Ohm 39Hz-150Hz 200/400 88.0dB 1 1/2" 25oz. 4 13/16"
T4108 10" Subwoofer 8 Ohm 40Hz-150Hz 200/400 88.1dB 1 1/2" 25oz. 4 7/8"
T41012 10" Subwoofer 12 Ohm 40Hz-150Hz 200/400 87.8dB 1 1/2" 25oz. 4 7/8"

When I am looking for the best possible performance from a specific driver, I call the manufacturer's tech department.

1-800-CALL-MTX is the one for MTX.

I just purchased Apline Type R's and it says in a pamplet in the box they came in how the box should be set up. Might be true for yours too but I don't know

Yeah, just remember that the instruction booklet was written by the marketing department, not the engineers. Small boxes sell better...they really do not care about performance, just sales.
