FSP118LEVBPH - (Forward firing version of Staiper ES18BPH)

what size were we aiming for again?

also rear chamber size.

big / small

lets explore the consequences

bigger: lower freq. ext., higher excursion - bumpy group delay

smaller : opposite.

I just want closest thing to this or the Boke MA828.

I've heard them both doing 60-180, and they work..
Might even buy some Bokes (used), and cut them in half... smiley24

both not efficient enough, I have one that is, but I'm not sharing it with the world smiley20

Is there some way you guys can protect the work so assholes don't build 100s of them in India and china?

close sites like this. Only have a selected few members that are vetted first

pray

60x60x60cm 18" BPH with 18B600

2pi 2,83v


0,5pi 1,41v


Unfortunately this size requires inverted driver install smiley24
I don't really get why it is unwanted.

The Boke MA828 is plenty efficient in the 60-180 band with Fanes/PD186 mate, have tried them..

Having <100db sens at 60hz or less, but 105db sens 80hz+ means lots of horrible upper bass, and no perceivable thump with the kick drum. Don't want that.

Sites like this are useful, when other sites like this are not working, or don't have freedom of speech..

Easiest thing to do is have locked plans forum, where only members of appropriate standing get access.

IMHO, response above 130hz is not quite as predicted, with inverted 18" drivers.

even so lev plans can end still end up in the wrong hands.........
