Advice on new sub direction

[peterpan]

Hello all, I have 2pcs DT300 Sub amps and want to build 2 subwoofers for stereo use. I want small SEALED(60 LITERS MAX) boxes that will work low. The following sub are available to buy, 1: adire shiva 2:emminence LAB12 3:ADIRE DPL12 and possible the TC2+ which will you go for, and what box size will fit.Room size is 13 by 14ft and 8ft high.

The DPL 12 has the lowest distortion and T/S parameters favorable to the approach you want to use in a sealed box.

I suggest you down load Unibox and run the parameters yourself for the drivers you're considering; this will give you a lot better feeling for what you're getting into.

The only other driver I'd suggest adding to your list for evaluation is the TC-Sounds TC2+, available from O-Audio. I'm using it in a dipole design, but it would work fairly well sealed, also. Small price premium, at $165. Very low distortion in the first +/- 10mm of travel.






Regards,

Jon

Other considerations are that a chunk of your 60L will be taken up by the plate amp and driver. Second if you want to play really low, the only way to do that with such a small box is to use a Linkwitz transform circuit. These generally must be custom built. Third use of drivers with a lower Vas might be a better option. The newly available BluePrint 1203, or Stryke AV12 should be considered.
