Kev Tshawb Xyuas Velodyne Qhov Tseeb Digital Subwoofers
Muaj ntau cov tuam txhab ua zoo subwoofers, tab sis thaum nws tawm mus rau cov suab ua hauv cov subwoofers, Velodyne yog tus thawj coj meej. Lub tuam txhab Digital Drive Plus subs yog, kom deb li deb li kuv paub, feem ntau ntawm kev ua lag luam, nrog cov ntse heev digitalization koj tuaj yeem teem los yog kev siv manually siv ib qho chaw calibration microphone. Tab sis lawv kuj yog cov feem ntau kim tshaj plaws nyob hauv lub khw.
Ob peb xyoos dhau los, Digital Drive technology tricked nyob rau hauv daim ntawv yooj yim rau ntau npaum EQ-Max series. Thaum CES 2014 nyob rau lub Ib Hlis, Velodyne tau pom qhov WI-Q series subs, 10- thiab 12-nti qauv uas muab cov kev pib EQ tshuab ntawm EQ-Max series nrog ib lub wireless transmitter.
About.com Tsev Kev Ua Yeeb Yam Kev Ua Si Robert Silva yuav tau saib $ 799 10-inch Wi-Q qauv. Kuv twb mus tawm rau nws, tab sis lub website HomeTheYourReview.com nug kuv saib xyuas qhov $ 899 12-nti qauv. Kuv tau ntsuas thaum kuv nyob ntawm nws, kuv xav khiav ib chav su ntawm kev ntsuam xyuas lab thiab xa lawv tuaj rau ntawm no. Yog li ntawm no peb mus ...

Velodyne WI-Q 12-Ntiag Tawm
Kev Tawm Sij Hawm
Hom 1 (Yeeb yam): 29 rau 123 Hz
Hom 2 (Pob Zeb): 33 mus 100 Hz
Hom 3 (Jazz / Classical): 32 mus rau 110 Hz
Hom 4 (Kev Ua Si): 38 mus rau 101 Hz
Daim duab saum toj no qhia txog qhov ntsuas ntawm qhov ntsuas Wi-Q 12-nti nrog qhov kev sib tw ntawm qhov sib npaug kom muaj siab tshaj plaws nyob rau hauv nws plaub hom sib txawv EQ: Movie (xim xiav), Pob zeb (liab kab), Jazz / Classical (ntsuab kab) thiab Kev Ua Si (ntshav liab kab). Kuv ntsuas cov lus teb no los ntawm cov neeg tsav tsheb thiab cov chaw nres nkoj, ua qhov ntsuas qhov chaw nres nkoj thiab sau lawv nrog tus neeg tsav tsheb ntsuas. Kuv cov cuab yeej yog ib qho Audiomatica Clio 10 FW suab analyzer thiab MIC-01 ntsuas microphone.
Jazz / Classical hom yog tsim los ua qhov kev ua suab nrov tshaj plaws, feem ntau nruab nrab suab nrov - thiab nws lub suab tsis tshaj - tab sis tus qauv qauv ua tau qhov kev teb thiab qhov dav tshaj plaws. Interestingly, cov kev ua si hom dials txoj kev rov qab rau cov zis hauv qab no 40 Hz, tej zaum yuav txo cov distortion thiab maximize cov zis.

Hla Txawj Qis Qis Tshaj Tawm
-21 dB / octave
Cov ntawv qhia no qhia txog qhov kev ua haujlwm ntawm Wi-Q 12-nti nrog qhov kev sib tw crossover rau 80 Hz hauv Jazz / Classical hom. Cov phiaj xim ntsuab yog lo lus teb nrog crossover bypassed, thiab cov kab ntxwv txiv kab ntxwv yog cov lus teb nrog 80 Hz crossover tshuab txais.

Kuv ua CEA-2010A bass output measurements siv lub Earthworks M30 ntsuas microphone, kuv M-Audio Mobile Pre USB interface thiab cov CEA-2010 ntsuas software tsim los ntawm Don Keele, uas sau rau hauv Wavemetric Igor Pro scientific software pob. Kuv tau siv cov kev ntsuas no tom 2 meters cov paib tawm, tom qab ntawd lawv ua kom tiav li 1-meter sib npaug ntawm CEA-2010A cov lus tshaj tawm. Ob qhov kev ntsuas ntawm kuv tau nthuav tawm ntawm no - CEA-2010A thiab txoj kev cai - yog qhov zoo tib yam tab sis rau txoj kev lawv tau scaled. Txoj kev cai hais tias feem ntau lub suab qiv ntawv thiab cov tuam txhab ua ntau cov ntaub ntawv qhia tau yog ntawm 2-meter RMS sib npaug, uas yog -9 dB qis dua CEA-2010A. L L tom ntej ntawm qhov tshwm sim qhia tau hais tias cov zis tau hais los ntawm subwoofer tus kheej hauv circuitry (xws li, limiter), thiab tsis yog dhau qhov CEA-2010A qhov cuam tshuam qhov sib txawv. Qhov nruab nrab yog xam rau hauv lub pas dej.
Cov kev ntsuas no yog ib qho tseem ceeb rau ib qho ntawm qhov loj me me thiab tus nqi. Tab sis lawv zoo li hauv qab no dab tsi yog tus thawj coj hauv chav kawm rau 12-inch ported subs, tus $ 799 SVS PB-2000, uas nws ntsuas tau pom ntawm no . Piv txwv, lub PB-2000 muab rau koj ntxiv +3.2 dB ntawm nruab nrab tso zis los ntawm 40 mus rau 63 Hz, thiab ib whopping ntxiv +13.2 dB ntawm tus nqi nruab nrab ntawm 20 thiab 31.5 Hz. Li ntawd, Wi-Q lub digital EQ muaj nuj nqi yog pib nqi koj ib qho ntxiv $ 100 ntxiv ntau ntawm cov zis hauv qab-octave.
Kuv tsis hnov tej lub suab nrov nrov thaum lub CEA-2010 xeem - qhov no hloov pace zoo - tab sis thaum kuv thawb Wi-Q 12-nti cov khoom tawm tswv yim nrog lub siab tawm qhov siab ntawm M-Audio interface, Kuv tau txais "ob thump" cov nyhuv thaum ua CEA-2010 - Kuv xav hnov cov "whop" ntawm lub CEA-2010 tone tawg, ces tus thib ob, qieter thump tom qab. Qhov no yeej tsis tau tshwm sim thaum kuv tseem tab tom ua cov khoom qub, li.
