Ukuhlola ama-Subwoofers we-Digital Digital
Izinkampani eziningi zenza ama-subwoofers amahle, kodwa uma kuziwa ekucubunguleni umsindo we-digital ngaphakathi kwe -subwoofers, u-Velodyne ungumholi ocacile. Ukubhaliswa kwe-Digital Drive Plus yenkampani kungukuthi ngiyazi, okuphambili kakhulu emakethe, nge-equalization ye-digital equalization ungasetha ngokuzenzekelayo noma ngesandla usebenzisa imakrofoni yokulinganisa. Kodwa nazo ziphakathi kwe-subs ebiza kakhulu emakethe.
Eminyakeni embalwa edlule, ubuchwepheshe be-Digital Drive bukhohlise phansi ifomu elilula kuya ochungechungeni oluthengwa kakhulu lwe-EQ-Max. Ku-CES 2014 ngoJanuwari, u-Velodyne ubonise i-Wi-Q series subs, ama-10-no-12-inch amamodeli ahlanganisa ubuchwepheshe be-EQ bochungechunge lwe-EQ-Max ne-transmitter engenafakiwe ehlanganisiwe.
I-About.com Home Theater Umhloli uRobert Silva uzobe ebuyekeza i-model ye-Wi-Q engu-$ 799 ye-10 intshi. Ngizoyishiya yona, kodwa i-HomeTheaterReview.com yewebhu ingibuze ukuthi ngibuyekeze i-$ 899 imodeli engu-12 intshi. Ngacabanga ngenkathi ngisekuyo, ngizogijima i-suite ephelele yamalinganiso webhu futhi ngiyithumele lapha. Ngakho lapha siya ...

I-Velodyne Wi-Q 12-Inch Frequency Response
Ukuphindaphindiwe impendulo
Imodi 1 (I-Movie): 29 kuya ku-123 Hz
Imodi 2 (iDwala): 33 kuya ku-100 Hz
Imodi 3 (Jazz / Yesiqalo): 32 kuya ku-110 Hz
Imodi 4 (Umdlalo): 38 kuya kwangu-101 Hz
Ishadi elingenhla libonisa impendulo elinganiselwe imvamisa ye-Wi-Q 12-inch sub nge-frequency crossover efakwe kuphezulu emidenjini yayo ehlukene ye-EQ: I-Movie (i-blue trace), i-Rock (i-trace ebomvu), i-Jazz / ye-Classical (i-trace eluhlaza) kanye nomdlalo (umlandeli obomvu). Ngalinganisa le mpendulo ngokuvala imoto umshayeli kanye namachweba, ukulinganisa izilinganiso ze-port bese ngifinyelela ngokulinganisa umshayeli. Amathuluzi ami kwakuyisicwaningi somsindo se-Audiomatica Clio 10 FW kanye nomakrofoni we-MIC-01 wokulinganisa.
Imodi ye-Jazz / ye-Classical ihloswe njengemodi ehlukumezekayo, engavumelani nezwe-futhi ibonakala ingathathi hlangothi - kodwa imodeli ye-Movie impela ihambisa impendulo enamandla kakhulu futhi evulekile. Ngokuthakazelisayo, imodi yegeyimu idlula emuva kokukhipha ngezansi kwe-40 Hz, mhlawumbe ukuze unciphise ukuphazamiseka nokwandisa umkhiqizo.

I-Velodyne Wi-Q 12-Inch Sub Crossover Impendulo
I-Crossover Low-Pass Rolloff
-21 dB / octave
Leli shidi libonisa umsebenzi we-crossover we-Wi-Q 12-inch sub nge-fressover imvamisa ebekwe ku-80 Hz kwimodi ye-Jazz / ye-Classical. I-trace eluhlaza yimpendulo ene-crossover ephasisiwe, futhi umkhondo we-orange ngumphendvulo nge-80 Hz crossover esebenze.

Velodyne Wi-Q 12-Inch Sub CEA-2010 Imiphumela
(Ukuphakama okungu-1M) (i-2M RMS)
40-63 Hz avg 116.5 dB 107.5 dB
63 Hz 119.6 dB L 110.6 dB L
50 Hz 116.0 dB L 107.0 dB L
40 Hz 112.6 dB L 103.6 dB L
20-31.5 Hz avg 103.1 dB 94.1 dB
31.5 Hz 109.3 dB 100.3 dB
25 Hz 100.0 dB 91.0 dB
20 Hz 91.8 dB 82.8 dB
Ngenza izilinganiso ze-CEA-2010A ezisezingeni eliphansi ngokusebenzisa i-microworks M30 yokulinganisa imakrofoni, isikhombimsebenzisi sami se-M-Audio Mobile Pre USB kanye nesofthiwe ye-freeware ye-CEA-2010 eyenziwe nguDon Keele, egijima kwi-software ye-software ye-Wavemetric Igor Pro yesayensi. Ngathatha lezi zilinganiso emkhatsini wemikhawulo engu-2 yamaprekhi, bese ngifinyelela ku-1-mitha elinganayo ngezimfuneko zokubika ze-CEA-2010A. Izilinganiso ezimbili ezilinganiselwe engizinikezile lapha - i-CEA-2010A kanye nendlela yendabuko - empeleni zifana kodwa ngendlela ehlelwa ngayo. Indlela yendabuko yamawebhusayithi amaningi alalelwayo nabakhiqizi abaningi abika imiphumela ilingana no-2-meter RMS elinganayo, okungu -9 dB ngaphansi kuka-CEA-2010A. I-L eceleni komphumela ibonisa ukuthi okukhiphayo kwashiwo yizifunda zangaphakathi ze-subwoofer (ie, limiter), hhayi ngokudlula imigqa ye-CEA-2010A yokuhlanekezela. Amaphesenti abalwa kuma-pascals.
Lezi zilinganiso zilungile kuyingxenye yalesi sayizi namanani. Kodwa ziphansi ngaphansi kwalokho okungenzeka ukuthi ungumholi weklasi nge-subs-inch ported subs, i-$ 799 SVS PB-2000, okulinganiselwe ukuthi ungayibona lapha . Isibonelo, i-PB-2000 ikunika okungeziwe +3.2 dB kokukhipha okuphakathi kokungu-40 kuya ku-63 Hz, nokufaka okungaphezulu kuka -13.2 dB kokukhipha okungaphezulu kokuphakathi kuka-20 no-31.5 Hz. Ngakho-ke umsebenzi we-digital EQ womsindo we-Wi-Q we-Wi-Q ngokuyinhloko ubiza imali engu-$ 100 kanye nokukhiqizwa okuningi kwe-bottom-octave.
Angizange ngizwe noma yikuphi umsindo wesiphakamiso uma kuhlolwa ukuhlolwa kwe-CEA-2010 - lokho kunguquko enhle yejubane - kodwa ngenkathi ngifaka ukungena kwe-Wi-Q 12-incher ngomoya ophezulu ophumayo kusuka kusixhumanisi se-M-Audio, Ngithole umphumela "wokuphindwa kabili" lapho ngenza i-CEA-2010 - Ngangizwa "i-whomp" yezwi le-CEA-2010 elaphukile, bese kuthi ngemva kwesibili, i-thump ngemuva. Lokhu akuzange kwenzeke lapho ngidlala izinto ezijwayelekile, noma kunjalo.
