On a ported speaker is there an easy way to make sure the drivers are sealed? I used a thin layer of silicone that I let dry well before putting in the driver. Or at low volumes is it even an issue?
Just like with an inner tube, you can brush on a soapy solution to look for bubbles when playing low frequencies. With measuring equipment, check cab tuning and if somewhat higher, bass rolled off, then there's a leak.
