My 8 yr old IDQ10dvc finnaly has gone to a better place :crap: I have a Type-R 12 (swr-1242d) that I picked up awhile back. I loved the sound of my IDQ in a small sealed encloser and it was'nt over powering.

I plan on buying a different woofer in the future, but for now I plan to use the Type-r. I will be using my Alpine MRD-M1001 for power. I don't want bass that is loud and boomy, nor do I wan't my trunk lid to rattle.

I have been using WinISD to model some vented enclosure ideas and what I came up with was a vented enclosure of 1.7cu_ft tuned to 22hz. this provided a nice arc similar to a sealed encloser with 30hz at -3db.
My original plan was to use it in a sealed enclosure but when I do a search for "Type-r 12 sealed" everyone says they didn't like it in a sealed enclosure. Why ?:confused:

So my questions are this.
: How does the Type-r 12 sound in a sealed encloser ( about 1.6cu ft) ?
: If I build a vented enclosure of 1.7cu ft.I is tuning to 22hz to low ?

All comments appreciated .

22 hz is way too low for a 12 I'd shoot for 32-35 hz

30-32 for me!

also, 1.6 sealed is pretty big. In all of my experiences, they lacked output when sealed but they didn't sound bad.

Honestly from personal experience I like it in a ported box. In addition, the box I heard it in was tuned to 33hz.
