Uvavanyo lweVelodyne lwe-Digital Digital Subwoofers
Uninzi lweenkampani zenza i-subwoofers enhle, kodwa xa kuziwa kwi-digital sound processing ngaphakathi kwe-subwoofers, u-Velodyne ungumkhokeli ocacileyo. I-subsistence ye-Digital Drive Plus yile nkampani, njengoko ndingazi, iyona nto iphambili kakhulu kwimarike, kunye ne-digital equalization equalization ungayibeka ngokuzenzekelayo okanye ngesandla usebenzisa imakrofoni yokulinganisela. Kodwa ziphakathi kwezinto ezibiza kakhulu kwiimarike.
Kwiminyaka emibini edlulileyo, ubuchwepheshe beDigid Drive bekhohlise ngefom elula kwi-series e-EQ-Max engathengiyo. Kwi-CES 2014 ngoJanuwari, uVelodyne ubonise i-Wi-Q series, i-10-no-12-intshi imodeli edibanisa ubuchwepheshe be-EQ ye-EQ-Max uchungechunge kunye ne-transmitter engenafowuni efakiwe.
I-About.com I-Home Theater Expert uRobert Silva uya kuhlaziya i-$ 799 ye-Wi-Q ye-10-intshi ye-Wi-Q. Ndiya kumshiya kuye, kodwa iWebhsayithi yeHomeTheaterReview.com yandicela ukuba ndihlaziye i-$ 899 ye-intshi ye-intshi ye-12. Ndacinga ngethuba ndilapho, ndiza kuqhuba i-suite epheleleyo yezilinganiso zebhu kunye nokuzithumela apha. Ngoko ke sihamba ...

I-Velodyne Wi-Q 12-intshi Ukuphendula ngokuphindaphindiweyo
Ukuphendula ngokuphindaphindiweyo
Indlela 1 (I-Movie): 29 ukuya ku-123 Hz
Imodi yesi-2 (iDwala): 33 ukuya kwi-100 Hz
Imodi 3 (iJazz / yeClastiki): 32 ukuya kwi-110 Hz
Imoya 4 (Umdlalo): 38 ukuya kwi-101 Hz
Isalathiso esingentla sibonisa impendulo ephindaphindiweyo ye-Wi-Q engama-intshi ye-intshi ezili-12 kunye ne-fressover imvamisa ebekwe kwii-modes zayo ezine ezahlukeneyo ze-EQ: I-Movie (i-trace blue), i-Rock (i-red trace), i-Jazz / i-Classical (ulandelelwano oluhlaza) kunye nomdlalo (umtsalane obomvu). Ndayilinganisa le mpendulo ngokuvala imida umqhubi kunye namachweba, ukulinganisa izilinganiso zefowuni nokuzifaka ngokulinganisa umqhubi. Izixhobo zam ziyi-Audiomatica Clio 10 I-analyzer ye-FW kunye ne-microphone ye-MIC-01.
Imodi yeJazz / yeClassical ijoliswe njengendlela engabonakaliyo, ininzi-engavumelaniyo-kwaye itywina ingathathi hlangothi - kodwa imodeli ye-Movie imele ihlangule impendulo enobunzima nangakumbi kunazo zonke. Ngokuthakazelisayo, imodeli yeMidlalo idibanisa indlela ephuma ngaphantsi kwe-40 Hz, mhlawumbi ukwenzela ukunciphisa ukuphazamiseka nokwandisa umkhiqizo.

I-Velodyne Wi-Q i-12-intshi ye-Sub Crossover Impendulo
I-Crossover i-Low-Pass Rolloff
-21 dB / octave
Le tshattshi ibonisa umsebenzi we-crossover we-Wi-Q 12-intshi encinci nge-fressover frequency ebekwe kwi-80 Hz kwimodi ye-Jazz / ye-Classical. Uluhlu oluhlaza luyimpendulo kunye ne-crossover ephawulwe, kwaye ulandelelwano lwe-orange ngumpendulo nge-80 Hz crossover eyenziwe.

I-Velodyne Wi-Q ye-12-intshi ye-CEA-2010 Iziphumo
(1M iphakamileyo) (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
Ndenza umlinganiselo we-CEA-2010A wokuphuma kwemveliso usebenzisa i-microworks M30 yokulinganisela imakrofoni, i-M-Audio ye-Mobile Pre Pre USB kunye ne-freeware software ye-CEA-2010 eyenziwe nguDon Keele, osebenza kwi-software ye-Wavemetric Igor Pro yesofthiwe yesayensi. Ndithatha le milinganiselo kwi-2 m mveliso yesiqhamo, ke ke ndayifumanisa ukuya kwi-1-mitha elinganayo kwiimfuno ze-CEA-2010A zokubika. Iisethi ezimbini zomlinganiselo endizibonayo apha - i-CEA-2010A kunye nemveli yendabuko - zifana ngokufanayo kodwa ngendlela eyahlukileyo ngayo. Indlela yendabuko ininzi yewebhusayithi kunye neentengiso ezininzi zibika iziphumo zilingana ne-R-meter ye-RMS elinganayo, eyi -9 dB ngaphantsi kwe-CEA-2010A. I-L ngokubhekiselele kwiphumo ibonisa ukuba umkhiqizo wawucaciswe ngabaphathi bee-subwoofer zangaphakathi (okt, i-limiter), kwaye kungekhona ngokugqithisa i-CEA-2010A. Umyinge ubalwa kuma-pascals.
Le milinganiselo ilungile kwisigxina salesi sikhulu kunye nexabiso. Kodwa ziphantsi ngaphantsi koko mhlawumbi inkokheli yeklasi ye-subs-port intshi e-12 intshi, i-$ 799 i-SVS PB-2000, eneemilinganiselo ozibonayo apha . Umzekelo, i-PB-2000 ikunika ngaphezulu +3.2 dB yemveliso ephakathi ukusuka kwi-40 ukuya kuma-63 iHz, kunye ne-extra +13.2 dB yemveliso engaphezulu kwe-20 ne-31.5 Hz. Ngoko umsebenzi we-EQ we-digital EQ ye-audio e-EQ ixabisa i-$ 100 eyongezelelweyo kunye nemveliso ephezulu ye-octave.
Andizange ndive nayiphi na isandi se-port xa siqhuba uvavanyo lwe-CEA-2010-leyo yinguqu enhle yezinga-kodwa xa ndiyifake igalelo le-Wi-Q 12-incher ngempumelelo yombane ophezulu ovela kwi-interface ye-M-Audio, Ndineempembelelo "eziphindwe kabini" xa wenza i-CEA-2010 - ndiva "inmpompo" yezwi le-CEA-2010 yaphuphuma, ibe yowesibili, i-thump emva. Oku akuzange kwenzeke xa ndidlala ukudla okuqhelekileyo, nangona kunjalo.
