Hello,

Before I commit to the upgrade of my enclosure and crossover components, I would appreciate the forums input on my decisions.

Crossover:
Current: 500Hz
Propossed: 1600 Hz

LF:
Driver: JBL 2226H
Current Enclosure Volume: 7 cu ft
Propossed Enclosure Volume: 5 cu ft

I have replaced my Eminence 15" Delta Pro with the JBL 2226H. Reducing my current enclosure to 5 cu ft. Two ports - diameter of 4", length 4".

HF:
Driver: JBL 2446J (16 ohm)
Currently my crossover is designed for 500Hz. The crossover will be changed to 1600 Hz, 12dB (2nd order) - Solen cap and Solen air core coil. My choice for L1 is 3.18 mH and C1 3.1uf - the driver is 16 ohms.

Other points of validation:
LF - I am choosing a 0.7 mH inductor for the LF crossover. Should I go air core - if so, what gauge.

HF - What gauge shoould I choose for the HF air core inductor.

Finally: any recommendations on bolt on speaker grills.

Thanks in advance
Jim
