Try completely disassembling the JBL Party Box Ultimate

Subwooferul z5500 cu tot cu incinta lui stock ar fi un boost de performanta mai ales în frecvente joase. N-are mare treaba watti cu spl produs. Ala e cel mai important ca decibeli auzim nu watti By The way: am un driver de subwoofer sony 8 inch BR100 model pus într-o incinta de 60 litrii acordata la 38hz într-o camera cu rezonanta la 35hz te ia pe sus și abia papa de la priza 10w

You probably know this but when you go from a 4 ohm driver to an 8 ohm driver, you lose half the power but you double the control of the cone so it should sound cleaner (damping factor). The lower the impedance the less and less controlled the bass will be. For example, I think one of my old car amps, an Alpine 500 Watt model, had a damping factor of 200 at 4ohms bridged but could do 2ohms but damping factor went down to 100. This means the subwoofer would not stop as fast so when the next note was to be played by the sub it would still be in motion from the last note resulting in less fidelity, muddier sound, and less hard hitting thump. I can say that I did hear a difference in overall bass clarity when I wired my home setup for 8 ohms bridged vs 4 ohms bridged on (2) 12" subs each in their own 4.6" cubic foot enclosures tuned to 21hz.
