|  Technical Specification * Sensitivity: 89 dB * RMS Power Range : 2500 Watts * Peak Power Handling: 6000 Watts * Impedance: Dual 4 Ohm * Low Frequency response: 18 Hz * High Frequency Response: 2000 Hz * Diameter: 12 Inch Features * 6000W Competition Class SPL dual voice coil subwoofer for professional use * Ohm Rating: 1 or 4 Ohm * Frequency Response: 18 � 2,000 Hz * Lowest Resonance Frequency: (Fs) 30 Hz * Qts: 0.34 * Vas: 26.7 (Litres) * Recommended Sealed Enclosure: 42.5 (Litres) * Sensitivity (1 W / 1 m): 89 dB * Nominal Input Power: 2500 W * Interlaced Carbon fi bre reinforced IMPP cone * 3-layer aramid fi bre woven radial rubber surround * Wide-roll, overhung surround * Super strong dust cap * Pure Titanium voice coil former * Ceramic-coated voice coil wire * Super Aramid fi bre damper * Button-hold design aluminium die-cast chassis * Powerful triple stacked magnets * ADMG (Aero Dynamic Magnetic Gap) * Extended and vented pole yoke * 8-gauge wire terminal * Priced per speaker * Subwoofers are usually come as a single speaker unless noted differently. NI SUBWOOFER POWER KA?BEGEGAR JUGA KA INI? tyco2 sound skalian mau tanya ni apa maksud tu Ohm,db,spl?mengapa ada 2-ohm,4-ohm,apa perbezaannya tu ah?! |

| klo tingu dri spec 2 memang power la...hehe
ohm 2 kn....om gere gere...haha...kiding2...ohm 2 ialah rintangan.suma bnda electrik ni ada rintanganya tersndiri...so ohm ni ialah sukatan rintangan.klo makin kecil 2 ohm, makin kuat la letrik da main, tapi brgntung dngn amp juga la.stabil tau tdk.woofer ni ada 2 voice coil.1 voice coil 2 ohm.so bleh wiring samada 4 ohm or 1 ohm la (wiring selari/bersiri)
sa suggest tngok2 la sekitar2 topik2 sini ni.macam bnyak suda org bincang psal ni.
db ndatau apa decibel kali, SPL sound pressure level (sound blaster). |

| ni mesti kes tdk bagi tumpuan masa bajar KH dlu kn  hehe tdk g2 complicated la, dlu kita ada blajar buat litar yg ada mentol 2 kn.konsep lebih kurang sama. parallel = selari (4ohm + 4ohm = 2 ohm) series = bersiri (4ohm + 4ohm = 8 ohm) kalau bersiri ohm akan bertmbah. selari ohm bekurang. cuba tngok gmbar 2 wiring (+) dan (-) ko bleh fhm 2 perbezaan parallel dan series. |

| itu ohm untk pakai monoblok......klu monoblok boleh turun 1ohm jadi klu pakai satu woofer mau pakai 2ohm+2ohm punya....klu pakai 2 woofer mau pakai 4ohm+4ohm bunya....sbb satu woofer 2hm+2ohm selari jadi 1ohm....klu 2 woofer 4ohm+4ohm selari 1ohm juga ......klu monoblok baru boleh turun 2ohm jadi main satu woofer mau 4ohm+4ohm selari jadi 2ohm......2 woofer pakai singel coil ... 4ohm + 4ohm selari jadi 2ohm......... |

| erm...tmbah bingung sa bca ni tau  ohm untuk pakai monoblock? bukn kah ohm ni wujud d semua peralatan elektronik.actly bukn monoblock sja yg ada kepelbagaian ohm yg bleh d support. amp 4 channel sya pn bleh main 4 / 2 ohm. 2 ohm bridge.itu bergntung amplifier ba 2. monoblock pn bukn suma stabil 1 ohm. |

| 4 channel boleh main 2ohm...tapi ia power kecil .... biasa 4 channel balu 50 rms per channel....main woofer kecil power boleh lah.... |

| yes...btul2...sokong2... bergntung kestabilan amp 2. jgn set yg amp 2 ta dpt angkat.klo tdk panas 2 amp.burn  paling pnting kena tengok 2 amp punya spec. |

| RMS tu power handling sbnar atau Continuous Power juga dkenali Mean Power,Average Power ssuatu speaker tu..bkn PMPO (peak music power output)maksud dia sy da lupa sbb msa skolah tgktn 4 lg so da lupa nnt sy refer balik okay...RMS tu mksd dia (root mean square).. |

| uhm mcmn mok ckp ni aaa...ko ni cgu pura2 xtaw pula aaa..scara teori dlm elktronik RMS adalah fundamental magnitude bg AC signal..means the RMS value assigned to an AC signal is the amount of DC required to produce an equivalent amount of heat in the same load...sori la geng blajar engineering mmg macam ni pkai english klu pkai mlay lg bngung ko nnt hehehe..macam aku jgk |

| uhm cgu root mean square ni adalah istilah sj...macam yg ckp td pwer handling sbnar atau average power ssbuah speaker tu..root mean square ni bmksud formula2 yg digunakan utk dapatkan jumlah power...lbih dgunakan utk pngiraan dlm bntk glombang..dmana nilai RMS adalah nisbah kpd crest factor (CF), |

| byk ohm makin xkuat la sbb ia adalah rintangan...biasanya pggunaan speaker yg bsar ohm ni spt PA system wat konsert tu,hi-fi alat elektronik rumah...sbb dia gn kuasa yg tinggi high voltage la katakan..macam kereta lg kcil ohm lg bgus sbb ia guna kuasa rendah 12 volt sj...klu guna ohm tinggi na pyah2 2 gink..tlampaw byk load suda tu hehehe..karen pun drop..kan dlm elktronik v=I/R dmana rintanagn bkadaran sgsang ngan arus dan voltan.. |
