The CSS TRIO 12 also has an introductory special, the sub itself for C$144 or the sub and two passive radiators for C$219.

The variables can't all be the same, each sub models differently due to the subs parameters and the application the sub is being used for. You're close on the TRIO12, and the Mack 5 should be 2.5 cu.ft tuned to 20 hz. It is also power hungry compared to the TRIO12.

Here's the modeling of the two. With 200 watts and the Mack 5 IXL-12 you can get away with one 4" port 31" long. The TRIO 12 needs a 6" diameter port 38" long.

Post the parameters for the TS-W301R, I can't find them. Thanks.

I don't have them with me at the moment. The driver files are here:

Your port speeds are fine. That design will take 500 watts with a Hi-Pass filter at 18 hz.

 

[Mike P.]

30 m/s is no problem for a 6" port, many have been built with no port noise issues.

 

[Mike P.]

Yup, that works. In the future when you upgrade the amp it will need a hi pass filter at 18 hz, assuming a power input of 500 watts.

This is the cone excursion of your sub. Yellow is 200 watts with no hi pass filter. The sub will start to bottom out at about 15 hz. As long as you go easy with the Rotel you'll be fine. Green is with 500 watts and a hi pass filter at 18 hz. Without one the sub will start bottoming out around 17 hz where there is a lot of low frequency information on DVD's.

Got any build pics?
