I never wanted to say this but I think my speaker cabinet are not tune right.I get some bass but not the way I thought I would. does any one know a company or some one who tune speaker cabs. My speakers are jbl 2245h -2202h -2425h-2404h. the cabs are 54 height- 24 witdh- 19 deep. I was told the ports should be 5 inch diam - 5 5/6 inch long that should be tune around 26 hz. the cabs are birch wood 3/4 thick thanks for any info gene
