Good day @ all
I have built a pair of 620 cabinets for my 604-8Gs but the bass is less than satisfying. Especially the mid bass is nowhere leaving the mid band hanging with no authority. Some very low bass <60 is there but that is all.
Calculating using TS parameters of the speaker, the cabinet suited is about 100liters!!! less than the 620. The result calculates at about 150liters and not 250 of the 620.
Where is the mistake?
Thanks in advance
