Hi,

I’m new at building speaker cabinets so I would like some help. I have 4 RCF LF18X400 and I want to build 4 compact bass reflex bass bins but I don’t know what to build. I was planning to make something similar to the EAW LA118 because the cabinet is easy to carry.

RCF LF18X400 Spec
Fs 28
Re 5.1
Qms 6.5
Qes 0.29
Qts 0.27
BL 25
Mms 192
Vas 340 liters
Sd 0.122
Xmax 9.0
Le1K 2.3
Eff 2.64

My version of the EAW LA 118

Width (Front) 24”
Width (Back) 16”
Height: 22”
Dept: 29”


Port Measurement
Width: 3”
Height: 20.5”
Length: 24.25”


Tuned @ 30Hz

Is my plan ANY good? Any other suggestions?
An externally hosted image should be here but it was not working when we last tested it.
 
I would suggest tuning it to 36Hz instead of 30Hz. You give up a good amount in the 40Hz range if you stay with the port length you listed.
