Searching for crossover schematic for Manzanita Ultra speakers. Any help would be greatly appreciated. Thanks

Welcome to AC 
Do you already googled it? Just found it on the firsts goo itens:
Is there any interest in a DIY kit for an excellent low cost open baffle speaker that is very easy and economical to build? I was going to build myself a pair, but I already have too many speakers and other projects going, so I have to pass on what I have assembled so far for someone else to complete.

The speaker is the DIY version of the Manzanita Ultra. The commercial version that John sells is shown here:
Manzanita Audio Solutions . Ultra CV

The DIY version you can build is described here:
Fast, fun, Inexpensive OB project

Start at post #851 and #1602 for the details on this Ultra build

I have the following parts for this DIY Ultra build:

Parts Express part numbers are as follows:

266-960 ERSE Super Q 20mH 16 AWG 500W Inductor Crossover Coil (cost new-$38.79)
255-434 Jantzen Audio 2.7mH 15 AWG Air Core Inductor Crossover Coil (cost new-$32.48)
027-236 Dayton Audio PMPC-6.2 6.2uF 250V Precision Audio Capacitor (cost new-$4.93)
005-15 Mills 15 Ohm 12W Non-Inductive Resistor (cost new-$4.25)
005-8 Mills 8 Ohm 12W Non-Inductive Resistor (cost new-$4.25)
091-1154 Parts Express Dual-Ended Gold Binding Post Speaker Terminal Pair (cost new-$7.80)
264-1062 Vifa TC9FD18-08 mid/tweeter (new in the box) (cost new-$ 12.53)

Some speaker wire is also included. Quantity 2 of each is included so the total new cost of the above parts would be $210.06

NOTE: You will still need to order the 2 GRS woofers from Parts Express:
Woofer. GRS-15PF-8 15" woofer. PE P/N 292-415 (cost new-$30.88)

As well as build your baffle and wire them up, etc.

Price is firm at $115 shipped within CONUS via USPS

Its a passive two way xover, If you dont want run the woofer full range direct I could use only a air core ribbon inductor as Goertz or Jantzen (avoid cheap iron core inductors) at the desired freq cut.

Seems they are doing correction with a circuit feed by a 9V battery due the small 12'' woofer placed away from the floor to dont use a bigger 15'' woofer.
