A padawan needs guidance here

[Madmike2]

This page and one other are where i am getting my dipole info and frankenstien calculation ideas from

http://www.snippets.org/alsr/index.php3#LARRAY

The info could be dated or i might be mis-interpreting something.
Gotta go to Starbucks and then place an order for more Cedar and Whitepine sheets.

A good starting point.... but you need to seek more widely

6 x NEO8 PLANAR TRANSDUCER
4 x DAYTON RS225S-8 8" REFERENCE SERIES SHIELDED WOOFER

Parallel Line array

Double spacing center to center on woofer line

Planar array 2 inch in trailing edge (inner) ^ inch to center alignment of woofer

54" tall by 36 inch wide (somewhere near a 1/4 wave length of a 95 hz....i think dont have calc with me at the gym here)

Isolated baffle for woofers which would nearly time align the planar and woofer mechanicaly

1 inch white poplar main baffle 1/4 inch white pine for baffle sandwich with 1/4 inch sonically inert foam to keep woofer vibrations off the main baffle of planar's

2 center woofer on each panel with 6db high pass at 120 and all 4 woofers lowpass at 18 db 1600 hz

planars high pass 24 db 1700

there is a phase veriance in this thought that i cant finger right now
probably my woofer choke is not smart

i am on my wireless right now so i dont have anyway of checking my frankenstien monster right now

am i glad i found this forum ....who do i make a decent donation to?

no more seeking i must build or i will turn to the dark side and buy ............................ BOSE !!

They aren't line arrays but since you have not proposed a real line array anyway...

Then i prescribe a pr of Visaton B200s, a 10" x 48" piece of wood -- a "leg". and a sheet of as big as you can live with foam, and build an OB. You'll need about 10W or so (more is OK, current amp probably better than voltage amp)

Sounds a bit similar to the design I mentioned here (though it was a full range dipole):

Completed neo3/pl14 line array - Thanks!

[Madmike2]

Hmmm so it seems people are getting BIG sound out of small driver situations.

[Madmike2]

Well i am going to do this for sure now. So you think that 2 baffles are nessicary per side? one for the tweeter line and one for the woofers ? Even if i can decouple the woofers from the planar line?
