SLA Pro box size

#1 Post by guido » Fri Jul 26, 2019 4:22 pm

I would like to build the SLA Pro with four 4 inch drivers and since the drivers go up to 20 Hz I plan to eliminate the tweeters. With no tweeters I was wondering how small I can go with the box dimensions. The drivers I am using are the Faital 4FE35.

I would just build an enclosure where each driver has .3cuft internal space that is ported to 55-60hz. Although the specs say 20k extension I struggle to believe that you will get that.

You'd use the box size in the plans for fours with or without tweeters. The cabinet volume is what's necessary for low frequency response.
