I am planning my HE system and slowly buying components. The system will include ES fullbodies, Beyma 8G40 in ported enclosures and i haven't still decided on a sub.
Some time ago i bought B&C 21SW152 on a whim and never used, so i thought maybe it would be a good candidate for a subwoofer in my new system.
Here are the specs:
I modeled in WinISD. Below are the graphs showing the SPL response with 700W applied.
Yellow graph shows the response in 60 liters sealed box (2,119 ft^3). That is about the volume i am going to get if i Build the box in a spare tire well. Purple graph shows the response of a vented box with tuning frequency at 32Hz. Both sims have cabin gain applied by the means of Linkqitz transform i estimated for my SUV (f0=56Hz, fp=15Hz, both Qs at 0,707), lowpass filter at 80Hz and a highpass filter at 80Hz.
Thinner orange and blue lines show the response of vented and sealed boxes respectively without the cabin gain.
Gray line is JL audio 12W6V2 in a vented enclosure tuned at 22Hz. Included for comparison.
Do you guys think i will be satisfied with this speaker? I used JL audio 12W6V2 in my previous install in a vented enclosure tuned at 22Hz and it played really low. I liked the character of its sound and the low notes it was able to play. But i think it lacked in 50-80Hz region. And i want this one from B&C to cover the full range from 25 to 80Hz and do that with authority.
Am i on the right track?
