Sorry, my bad, that is volume for the double 12. Try 40 lit.

I am loving the look of the volt 220.1 but unfortunately it is discontinued..
Are there any known alternatives?

Hi Marjan The BMS is great in a 40L box it shows a bass hump with 45hz tuning and could be tuned to below 40hz Sim shows BMS 50w 40L 40hz against Beyma 50w 90L 47hz You can see what reducing the size does, it throws away 5db of output so needs 3 times the power - not so good on batteries.

Monkeys: Why not download winisd and sim them for yourself? You'll learn enough doing it to answer many of your own questions!

What about using 2 x 10" passive radiators (one on each side) opposed to a port / horn?
Interested to follow this build, please make sure to post updates and images, considering something similar myself.

Can you explain the advantages you would see from that vs a port? If I understsnd correctly that sounds akin to a boominator, which didn't really appeal to me for this project. Im going for more of a "mini standard PA speaker" type dealio with this. endeavour. So somewhat directional, high quality sound that covers most of the full range, doesnt need to be super loud, that can be paired with a second unit for stereo.

A Boominator has 2 active drivers back to back which effectively increased the overall efficiency of the system and uses 2 ports. (Has no passive radiators)
A passive radiator is used instead of a port / bass reflex so works in a similar way. Typically you will use 2x 10" passive radiators to 1 x 10" Active driver if they have a similar Xmax. (See the below youtube video for an example subwoofer with passive radiators) Have a little google of the benefits as you'll find better information than I can give. Here are some links to get started. Hope this helps! |
