ʻO nā loea Bass haʻahaʻa loa - Mahele 2

ʻAʻole ikaika nā subwoofers i nā manawa a pau, ʻaʻole pili mau i nā ʻōnaehana hale kiʻiʻoniʻoni, a ʻaʻole i lawelawe mua iā lākou. Ua hoʻomaka lākou i kā lākou ʻoihana ma ka ʻenehana kaulana i ka hopena o nā makahiki 80, ma nā ʻōnaehana stereo i pili i nā mea hoʻokani stereo "maʻamau" ma mua o nā mea hoʻokipa multi-channel - ke kokoke mai nei ke au o ka hale keaka.

Pūnaehana 2.1 (ʻo kahi subwoofer me ʻelua mau satelite) he mea ʻē aʻe i ka pālua o nā mea kamaʻilio kahiko (e nānā pū: ) me ka ʻole o nā koi. Ua manaʻo ʻia kēia e hoʻohana i ka subwoofer passively low-pass-filtered a me nā satelite passively high-pass-filtered, akā ʻaʻole ʻokoʻa kēia haʻawe ma ka ʻaoʻao impedance "ʻike ʻia" e ka amplifier ma mua o ka ukana o kahi multi- ala ʻōnaehana leo kani. ʻOkoʻa wale nō i ka māhele kino o ka ʻōnaehana multi-way i kahi subwoofer a me nā satelite, ma ka ʻaoʻao uila he ʻano like ia (ua loaʻa pinepine nā subwoofers ʻelua woofers i hoʻopili kūʻokoʻa i ʻelua kahawai, a i ʻole hoʻokahi mea ʻōlelo lua-coil).

ʻO ka papa amplifier me ka ʻāpana hoʻomalu ʻaneʻane aia ma ke kua - ʻaʻole pono mākou e kipa i kēlā me kēia lā

Pūnaehana 2.1 Ua loaʻa iā lākou ka kaulana nui ma kēia kuleana (Jamo, Bose), poina ma hope, no ka mea, ua kāohi ʻia lākou e nā mea āpau. ʻōnaehana hale kiʻiʻoniʻoniʻO, ua hala ʻole me nā subwoofers - akā nā mea ikaika. Ua hoʻololi kēia mau mea i nā subwoofer passive, a inā i kēia lā e noʻonoʻo kekahi e pili ana i kahi ʻōnaehana 2.1 i hoʻolālā ʻia no ka hoʻolohe ʻana i ke mele (pinepine), a laila e noʻonoʻo paha lākou i kahi ʻōnaehana me kahi subwoofer ikaika.

I ko lakou puka ana mai nā ʻano hoʻoheheʻe lehulehu i ʻōnaehana hale kiʻiʻoniʻoni, ua hoʻokumu lākou i kahi alapine haʻahaʻa kūikawā - LFE. ʻO ka manaʻo manaʻo, hiki i kāna amplifier ke lilo i waena o nā mana amplifiers he nui o kahi amplifier AV, a laila pasive ka subwoofer pili. Eia nō naʻe, ua nui nā manaʻo hoʻopaʻapaʻa e pili ana i ka mālama ʻokoʻa ʻana i kēia kahawai - pono e "wehe ʻia" kēia amplifier mai ka mea AV a hoʻohui pū me ka subwoofer. ʻO kēia ke koho maikaʻi loa nona ʻaʻole wale i ka mana akā i ka hana pū kekahi. Hiki ke hoʻoponopono maikaʻi a hoʻokō i kahi alapine ʻoki ʻoki haʻahaʻa ma mua o kahi subwoofer passive o ka nui like a me kahi mea haʻi'ōlelo like, e hoʻohana i kahi kānana low-pass ikaika a hiki ke hoʻololi ʻia (kahi kānana passive low-pass ma kēlā mau kānana haʻahaʻa. ʻoi aku ka ikaika a me ke kumukūʻai), a i kēia manawa e hoʻohui i nā hana hou aʻe. I kēia hihia, "hoʻokuʻu ʻia" ka amplifier multichannel (receiver) mai ka mana amplifier, a ma ka hoʻomaʻamaʻa ʻana e ʻoi aku ka maikaʻi loa (pono ke kahawai LFE i ka mana e hoʻohālikelike ʻia me ka mana piha o nā kahawai ʻē aʻe o ka ʻōnaehana). !), ka mea e koi ai iā mākou e haʻalele i ka manaʻo nani o ka mana like no nā pahu āpau i hoʻokomo ʻia i ka mea hoʻokipa, a i ʻole e kaupalena i ka mana o ke kahawai LFE, e hōʻemi ana i nā hiki o ka ʻōnaehana holoʻokoʻa. ʻO ka hope, hiki i ka mea hoʻohana ke koho manuahi i ka subwoofer me ka ʻole e hopohopo e pili ana i ka hoʻohālikelike ʻana me ka amplifier.

A i ʻole me ke mele ʻōnaehana stereo ʻOi aku ka maikaʻi o ka subwoofer passive? E pane kākou i kēia: No nā ʻōnaehana multi-channel/cinema, ʻoi aku ka maikaʻi o ka subwoofer ikaika, pololei ka manaʻo o ia ʻōnaehana ma nā ʻano āpau, e like me kā mākou i kūkākūkā ai. No nā ʻōnaehana stereo/mele, ʻo kahi subwoofer ikaika kahi hopena kūpono, ʻoiai ʻaʻole nui nā hoʻopaʻapaʻa i kona makemake. ʻO kahi subwoofer passive i loko o ia mau ʻōnaehana e ʻoi aku ka manaʻo, ʻoi aku ka maikaʻi inā loaʻa iā mākou kahi amplifier ikaika (stereo), akā pono mākou e noʻonoʻo pono a hoʻolālā i nā mea āpau. A i ʻole, ʻaʻole mākou e ʻike i ka mākaukau, passive 2.1 ʻōnaehana ma ka mākeke, no laila e koi ʻia mākou e hui.

Pehea mākou e hana ai i ka mahele? Pono e loaʻa i ka subwoofer kahi kānana ala haʻahaʻa. Akā, e hoʻokomo mākou i kahi kānana kiʻekiʻe no nā mea ʻōlelo nui, e hana ana i kēia manawa ma ke ʻano he satellite? ʻO ka hiki ʻana o ia ʻano hopena e pili ana i nā kumu he nui - ka bandwidth o kēia mau mea ʻōlelo, ko lākou mana, a me ka mana o ka amplifier a me kona hiki ke hana me ka haʻahaʻa haʻahaʻa; He mea paʻakikī paha ka hoʻohuli ʻana i nā leo leo a me ka subwoofer i ka manawa like (e hoʻopili like ʻia kā lākou impedances, a e emi iho ka impedance hopena). No laila ... ʻo ka mea mua, ʻo kahi subwoofer ikaika kahi hopena maikaʻi a ākea, a me kahi passive - i nā kūlana kūikawā a me ka ʻike nui a me ka ʻike o kahi mea amateur o ia ʻōnaehana.

Hoʻohui ʻōlelo

ʻO kahi pūʻulu hoʻohui waiwai loa - nā mea hoʻokomo RCA, nā mea ʻōlelo a, kakaʻikahi loa, kahi puka kānana kiʻekiʻe (ʻelua ʻelua o RCA)

ʻO kēia pili, ʻo ka mea nui loa no nā subwoofers, ua lilo i mea nui i ka manawa ma nā ʻōnaehana AV a mākou e hoʻolako pinepine ai. LFE Hoailona Haahaa i hoʻokahi mea hoʻohui RCA, a "no ka hihia" aia kekahi mau RCA no nā hoʻopili stereo. Eia nō naʻe, ʻo ka hoʻopili ʻana me ke kelepona ʻōlelo he mau mea maikaʻi a me kāna mau kākoʻo. He mea koʻikoʻi ka pilina o ka leo i nā ʻōnaehana stereo, ʻoiai ʻaʻole nā ​​​​amplifiers āpau i nā haʻahaʻa haʻahaʻa haʻahaʻa (mai ka preamplifier) ​​a ma muli o nā ʻāpana hōʻailona kikoʻī. Akā, ʻaʻole ia he hōʻailona kiʻekiʻe; ʻAʻole hoʻopau ka subwoofer i ka mana mai kahi amplifier waho me kēia pili, no ka mea ʻaʻole ʻae ka impedance kiʻekiʻe; Eia kekahi, me kēia pili, e like me ka haʻahaʻa haʻahaʻa (i nā mea hoʻohui RCA), hoʻonui ʻia ka hōʻailona e nā kaapuni subwoofer.

ʻO ka mea ʻoiaʻiʻo me kahi pilina (speaker), ʻo ka hōʻailona i ka subwoofer e hele mai i nā huahana like (external amplifier), me ka pae like a me ka "character" e like me nā mea ʻōlelo nui. He mea paʻakikī kēia hoʻopaʻapaʻa, no ka mea... Hoʻololi hou ka hōʻailona i ka amplifier subwoofer, ʻokoʻa, pono e hoʻoponopono ʻia ka pae, akā ʻo ka manaʻo o ke kūlike o nā hōʻailona e hele ana i nā mea haʻi'ōlelo a me ka subwoofer e hoʻopiʻi i ka noʻonoʻo ... aia wale nō nā mea pono a pau.

ʻĀpana wai a i ʻole ka pae lele?

ʻO nā mea hana maʻamau: maʻemaʻe ka pae a me ka kānana ʻana, ua pae ʻia nā pae; lua o ka stereo RCA me ka hoʻokomo LFE hou

ʻEkolu mau hoʻololi nui o ka subwoofer ikaika e ʻae iā ʻoe e hoʻololi i ka pae (volume), palena alapine kiʻekiʻe (i kapa ʻia ʻoki ʻoki) i manawa. ʻO nā mea mua ʻelua he wai maʻamau, ʻo ke kolu paheʻe a paʻa paha (ʻelua kūlana). He kuʻikahi koʻikoʻi kēia? Nui nā mea hana e hoʻoholo e hana i kēia ʻaʻole wale i nā subwoofers cheap. ʻO ka hoʻonohonoho ʻana i ka pae kūpono, ʻoiai he mea pono loa ia no ka alignment maikaʻi, ma ka hoʻomaʻamaʻa ʻana i ka hana liʻiliʻi loa a mālama ʻole ʻia e nā mea hoʻohana. ʻOiai ʻo ka hoʻolohe ʻana i ke ala ʻoi loa ke ala maikaʻi loa e hoʻokani i kahi subwoofer i nā satelite, ʻoi aku ka paʻakikī o ka hana a no laila paʻakikī a nānā ʻole ʻia. A pēlā me ka hoʻoponopono pae a me ka kānana ʻana he pōʻino loa ia... ʻO ka ʻae ʻana i kēlā ʻano kuʻikahi (hoʻololi ma mua o ka pihi), paipai mākou i nā mea hoʻohana e hoʻāʻo ma ke ʻano maʻalahi: e hoʻoholo wale i ke kūlana hoʻololi ʻoi aku ka maikaʻi (ʻoi aku ka bass ʻoi aku ka maikaʻi o ka pae kaulike. ), me ka ʻole o ka ʻimi hoʻoluhi i ka mea kūpono me ka nui o nā paʻi lima. No laila inā loaʻa iā mākou nā hoʻoponopono maʻalahi, e hoʻāʻo mākou i nā kūlana kiʻekiʻe loa, ʻo ia hoʻi. ʻokoʻa e 180 °, a ʻike maoli mākou i ka ʻokoʻa. I nā hihia koʻikoʻi, ʻo kahi pae i hoʻonohonoho hewa ʻia ʻo ia ka lua hohonu o nā hiʻohiʻona, a ʻo ka "under-adjusted" wale nō ke ʻano o ka nāwaliwali.

ʻOhi kikowaena

A hiki i kēia manawa, ua hoʻolako ʻia kahi helu liʻiliʻi o nā subwoofers ka hoʻohana ʻana i ka mana mamao - no lākou, ʻo ia nō nā mea waiwai nui, ʻoiai he mea kūpono loa, no ka mea, ʻo ka hoʻonohonoho ʻana i ka subwoofer mai ke kūlana hoʻolohe e kōkua nui i ka loaʻa ʻana o nā hopena maikaʻi loa. ʻOi aku ka maikaʻi o ka hana ʻana i kekahi ʻano ʻē aʻe ma mua o ka holo ʻana i hope ma waena o ka noho a me ka subwoofer. Eia nō naʻe, ʻo ka manaʻolana e lilo ka mamao i mea maʻamau, a e maʻalahi a ʻoi aku ka maʻalahi o nā hoʻonohonoho subwoofer e hoʻomaikaʻi i nā polokalamu no nā lako kelepona - ʻoi aku ka liʻiliʻi o kēia hopena ma mua o ka hoʻohui ʻana i kahi mamao, a wehe pū kekahi. nā mea hiki.

E akahele! ʻŌlelo nui!

Loaʻa nā subwoofers mai nā mea ʻōlelo nui He liʻiliʻi ka woofers ... weliweli. ʻO ka hana ʻana i ka leo leo nui ʻaʻole ia he kiʻi maikaʻi - ʻaʻole pono ka hīnaʻi anawaena nui a me ka diaphragm i nā kumukūʻai, hilinaʻi nui lākou i ka maikaʻi (a no laila ka nui) o ka ʻōnaehana magnetic, e hoʻoholo ai i nā ʻāpana koʻikoʻi. Ma kēia kumu, ma ke koho kūpono o nā hiʻohiʻona hoʻolālā ʻē aʻe (coil, diaphragm), ka mana, ka pono, ka haʻahaʻa haʻahaʻa, a me ka pane impulse maikaʻi i kūkulu ʻia. He pōʻino ka ʻōlelo nui a nāwaliwali, ʻoi aku hoʻi ma kahi ʻōnaehana hoʻihoʻi bass.

ʻO ia paha ke kumu e makaʻala ai kekahi poʻe i nā woofers nui (ma nā leo kani), e hoʻopiʻi pinepine iā lākou no ka "lohi", e like me ka ʻike ʻia e ka diaphragm koʻikoʻi. Eia nō naʻe, inā hoʻokele ka ʻōnaehana oscillatory kaumaha i kahi "drive", a laila hiki ke hoʻonohonoho ʻia nā mea a pau, ma kahi leo kani passive a me kahi subwoofer hana. Akā e makaʻala - ʻaʻole e uku ʻia ka nāwaliwali o ka magnet e ka mana kiʻekiʻe o ka amplifier a i ʻole kona pono (i kēia manawa, a me nā mea ʻē aʻe), i hāʻawi ʻia e kekahi mau mea hana. ʻO ke au o ka booster e like me ka wahie, a ʻo ka wahie maikaʻi loa ʻaʻole ia e hoʻomaikaʻi nui i ka hana o kahi mīkini nāwaliwali.

Hiki ke hoʻopuka i nā hopena like ʻole, ka leo kani (waho) a me nā haneli he nui, ma muli o ka mana a me ka hoʻonohonoho ʻana o ka ʻōnaehana hoʻokele leo leo.

ʻOi loa i ka hihia o kahi bass reflex, "haʻi" e kahi magnet nāwaliwali (a / a i ʻole ka liʻiliʻi liʻiliʻi o ka hale hale), ʻaʻole hiki ke "hoʻopaʻa ʻia" ka pane impulse e ka mana mai ka amplifier, hiki ke hoʻohana ʻia e hoʻoponopono i ke alapine. pane, no laila i loko o nā subwoofers ikaika - ʻoi aku ka pinepine ma mua o nā mea ʻōlelo - ua hoʻohana ʻia ke kino paʻa. Akā hoʻihoʻi bass hoʻowalewale ʻo ia me kāna ʻoihana kiʻekiʻe, hiki ke pāʻani i ka leo nui, ʻoi aku ka maikaʻi ... a ʻaʻole koʻikoʻi ka pololei o nā pahū i loko o kahi hale keaka. ʻOi aku ka maikaʻi o ka loaʻa ʻana o nā mea āpau i ka manawa hoʻokahi, e koi ana i kahi leo leo paʻa (ma nā ʻano āpau), ka mana kiʻekiʻe mai ka amplifier a me kahi pahu me ka leo maikaʻi loa. ʻO kēia mau mea a pau ke kālā, no laila, ʻaʻole maʻamau nā subwoofers nui a maikaʻi. Akā aia nā "kumu," akā no ka loaʻa ʻana iā lākou, ʻaʻole lawa ka nānā ʻana i ka subwoofer mai waho, heluhelu i kāna mau hiʻohiʻona ponoʻī, a i ʻole e hoʻopili a nānā i kekahi mau hoʻonohonoho maʻamau i loko o kahi lumi maʻamau. ʻOi aku ka maikaʻi e ʻike i nā "ʻoiaʻiʻo paʻakikī" ... i kā mākou hoʻāʻo a me nā ana.

Grille - wehe?

W mau leo ​​leo nui ʻO ka pilikia o ka mana o ka mask ma nā ʻano hana e noʻonoʻo mākou i kā mākou mau ana ma ka hoʻohālikelike ʻana i ke kūlana (ma ka axis nui) me ka ʻole o ka mask. Aneane maopopo loa ka ʻokoʻa (i ka pōʻino o ka grille) a manaʻo mākou e wehe, i kekahi manawa maopopo loa.

I ka hihia o nā subwoofers, ʻaʻole mākou e pilikia i kēia, no ka mea, ʻaʻohe grille e hoʻololi i ka hana i kahi pae ʻike. E like me kā mākou i wehewehe pinepine ai, typical gratings ʻAʻole lākou e hoʻohuli nui i ka radiation e ka mea i uhi ʻia ka leo leo, akā ma ke kiʻi i kau ʻia ai kēia mea. ʻO ka attenuation i hoʻokomo ʻia e nā ʻiʻo maʻamau he liʻiliʻi, akā ʻike ʻia nā nalu pōkole o ka waena a me nā alapine kiʻekiʻe mai nā scaffolds, ke keʻakeʻa ʻana a no laila e hoʻokumu i nā ʻano like ʻole i nā ʻano. I ka hihia o nā subwoofers, ʻoi aku ka lōʻihi o nā nalu haʻahaʻa haʻahaʻa a lākou e hoʻopuka ai (e pili ana i ka mānoanoa o nā kiʻi), no laila ʻaʻole i ʻike ʻia mai lākou, akā "holo a puni" e like me nā ʻaoʻao o ka hihia. e laha wale ana a ma na aoao a pau. No laila, hiki ke waiho maluhia ʻia nā subwoofers me nā grilles, ʻoiai ... ikaika a paʻa maikaʻi lākou i ʻole e komo i loko o nā haʻalulu ma kekahi mau alapine a me nā pae leo kiʻekiʻe, e hana ʻia i kekahi manawa.

ʻO ka hoʻoili uila ʻole ke koho pinepine ʻia a koi ʻia ke kūʻai ʻana i kahi module kūikawā, akā ke kali nei ke awa o ka subwoofer iā ia.

ʻOmnidirectional

Ke ana ʻana i nā subwoofers, ʻaʻole mākou e noʻonoʻo i nā hiʻohiʻona kuhikuhi, no laila ʻaʻole mākou e ana i nā ʻano hana mai nā kihi like ʻole. He mea paʻakikī ke kamaʻilio e pili ana i ke koʻi kahi i hana ʻia ai ke ana, no ka mea, ʻo ia ka mea i kapa ʻia ke ana kokoke - (e like me ka amplitude o kāna hana e hiki ai). ʻO nā alapine haʻahaʻa, ma muli o ko lākou mau nalu lōʻihi, ʻoi aku ka nui ma mua o ka nui o kahi woofer nui a me kona pā, hoʻolaha i ka omnidirectionally (spherical wave), ʻo ia ke kumu nui o ka hoʻohana ʻana i nā ʻōnaehana subwoofer ma ke ʻano nui. No laila, ʻaʻole ia he mea koʻikoʻi inā pili pololei ka subwoofer i ka mea hoʻolohe a i ʻole ma ka ʻaoʻao, hiki nō ia ma ka ʻaoʻao lalo ... No laila ʻaʻohe pono e "hoʻokō" i ka subwoofer ma ke kūlana hoʻolohe. ʻaʻole i manaʻo ʻaʻole mālama iki i kahi e kū ai.
