HD 215

Hello forum,

I'm a long time reader and just have registered because I'm planning to build 4 HD215 with PD1550 which I have laying around for quite some time... .
My questions is : Is the panel in the middle really required if i "sandwich" two normal HD15 together ?
Obviously you need something to direct the soundwaves to the front but would a V where the two "Horns" start be enough ?

Thank you for the reply :)

I just wanted to be sure because i build 3 types of cab's (own design) but they were just to complicated to build and I was not very pleased with the sound either.

At the moment i just want to build some kicking bass cabinets and thougt the HD15 or the doubled version HD215 would be a great choice ( I will need something for the low end in the future for sure) .

 I've never heard an Bandpasshorn before but from reading 100s of pages here i think they are the right cabs for heavy Techno but recommendations are always welcome if you have more vesatile suggestions :)

Greetings dennis

Edit: added pictures my current version

Yes my originally plan was to go as low and braodband as possible but as i realized and learned later W-Bins sound ... kind of "strange" in the upper regions.

I just digged out the hornresp data for (which i assume ) this horn.





Maybe you have some suggestions what i have done "wrong" or shoudl/could change
