Sonance tus SB46 soundbar yog ib qho qauv tshiab uas cov tshuab telescopes kom nws raws nraim qhov luaj li cas ntawm lub pav ca-TV. Qhov loj version, qhov $ 2,000 SB46 L, yog tsim rau TVs tsuas yog los ntawm 70 mus rau 80 nti. Nov yog tag nrho cov kev ntsuas rau SB46.
01 ntawm 04
Sonance SB46 L Kev Ntsuas: Kev Tshaj Tawm Txog Kev Nyab Xeeb
Tawm cov lus teb, tshuav channel
On-axis: 98 Hz mus rau 20 kHz ± 5.1 dB, ± 4.8 dB rau 10 kHz
Avg 0 ° rau 30 °: 98 Hz txog 20 kHz ± 3.4 dB (tib mus rau 10 kHz)
Kev hloov lub sij hawm, qhov chaw channel
On-axis: 98 Hz mus rau 20 kHz ± 6.5 dB, ± 4.2 dB rau 10 kHz
Avg 0 ° rau 30 °: 98 Hz rau 20 kHz ± 4.7 dB, ± 2.7 dB rau 10 kHz
Ntawm no yog qhov kev ntsuas ntau zaus ntawm SB46 L. Kev ntsuas ntawm qhov chaw zov me nyuam muaj qhov ntsuas tawm -10 dB ces koj tuaj yeem pom lawv zoo dua. Qhov ntawd yog cov sab laug ntawm 0 ° rau-axis (xiav kab) thiab nruab nrab ntawm 0 °, ± 15 ° thiab ± 30 ° (ntsuab ib txoj lw). Hauv qab nws yog qhov chaw channel ntawm 0 ° on-axis (ntshav liab kab) thiab nruab nrab ntawm 0 °, ± 15 ° thiab ± 30 ° (txiv kab ntxwv ib txoj lw). Koj tuaj yeem pom tias cov lus teb ntawm ob qhov ntawm 2 thiab 5 kHz kuj nce mentsis kom siab, uas yog qhov ua rau ntawm qhov ci ntsa iab uas kuv hnov.
Lus hauv no teb Qhov no yog ua ncaj ncaj teb rau ib lub suab lus, tshwj xeeb tshaj yog nyob rau hauv qhov chaw channel, uas yog qhov tseem voj voog rau 6 kHz. Daim duab tom ntej no qhia tau ntau dua.

Sonance SB46 L Kev ntsuas: Left & Center Compared
Qhov no yog lo lus teb ntawm SB46 L tshuav channel (kab xiav) thiab nruab nrab channel (liab kab), ob qho tib si ntawm 0 ° on-axis Thaum lub chaw channel muaj tib qho cim ua rau sab laug, nws ntsuas ntau flatter tag nrho. Tias 's tus zoo tshaj plaws hauv feem ntau, tab sis nws' s yog vim li cas lub SB46 L suab zoo dua nrog tsos (uas feem ntau hnyav hnyav ncawv rau ntawm qhov chaw channel) dua nrog suab paj nruag.

Sonance SB46 Kev Ntsuas: Impedance
Empedance (yam tsawg / nominal)
sab laug / txoj cai channel: min 4.6 ohms ntawm 298 Hz / -28 dej, nominal 7 ohms
center channel: min 3.9 ohms ntawm 302 Hz / -32 deg, nominal 8 ohms
Teeb meem (2.83V / 1W @ 1 meter, quasi-anechoic)
sab laug / txoj cai channel: 82.1 dB
chaw channel: 84.0 dB
Daim duab no qhia tau hais tias sab laug ntawm lub plhaub taum ploj (qhov xiav xiav kab) thiab theem (lub teeb xiav kab), thiab qhov chaw nruab nrab ntawm qhov muaj zog ntawm huab cua (qhov xim ntsuab ntsuab) thiab theem (lub teeb ntsuab kab). Muaj ib qho loj loj hauv impedance thiab ib theem loj ua haujlwm hauv qab 100 Hz, tiam sis qhov ntawd yog nyob hauv qab ntawm qhov kev khiav hauj lwm ntau ntawm lub suab lus kom nws tsis txhob yog qhov teeb meem tseem ceeb.
Qhov kev xav tsis siab heev, tab sis qhov no yog kev ntsuam xyuas cov quasi-anechoic. Hauv chav tsev, koj yuav zaum tau ib qho ntxiv +3 dB los yog li ntawd. Tseem, qhov kev ntaus suab no yuav ua hauj lwm zoo tshaj plaws nrog ib tus neeg tau txais txiaj ntsig zoo los yog zoo dua los yog ib tus nyias muaj nyias amp, ib yam dab tsi nrog lub zog ntawm lub hwj chim.

Yuav ua li cas qhov Sonance SB46 L Soundbar Measurements Tau Txais
Cov kev ntsuam no tau coj siv Audiomatica Clio 10 FW suab analyzer (pom saum toj no) thiab MIC-01 ntsuas microphone, tom qab xa cov ntaub ntawv mus rau hauv LinearX LMS analyzer rau kev ua tiav. Qhov kev xeem siv cov txheej txheem quasi-anechoic, uas tshem tawm cov teebmeem ntawm reflections los ntawm cov khoom nyob ze.
Tus curves uas koj pom hauv cov kab kos tau sib npaug mus rau 1/12 th octave. Bass lus teb ntawm cov neeg hais lus raug siv los ntawm kev siv cov txheej txheem kaw, nrog rau qhov chaw nyob ze ze ntawm qhov ua tau zoo rau ib qho ntawm cov woofers rau txhua lub. Cov kev ntsuam no raug scaled paab, ces spliced rau kev ntsuam xyuas quasi-anechoic ntawm 275 Hz. Cov qhab nias tau raug ua rau 0 dB ntawm 1 kHz.
Rau ntau qhov tob ntxiv (tseem siv tau yooj yim) ntawm kev hais lus, nyeem kuv daim ntawv txheeb ntawm kev kawm (PDF), ua tiav nrog kev pab los ntawm cov kws tsim ntawm Harman International.
