Kev pab txhim kho lub hwjchim no, tus tsav npav muaj tus hlau nplaws uas HSU Kev Tshawb Fawb hais tias yog qhov loj ntawm ib qho ntawm tus qub VTF-15H. Pro-style XLR balanced stereo inputs tau ntxiv, thiab ib qho me me kub dab txuas rau tom qab vaj huam sib luag.
Tus qauv tshiab yog hloov me ntsis hauv nws qhov ntev. Nws yog ib nti shorter, uas tso cai rau HSU Tshawb nrhiav kom tau tus nqi qis tshaj ntawm shipping. Tus nqi ntawm lub sub mus li, tab sis shipping nqi poob, yog li tus qauv tshiab tau nce nqi txog tib yam li nws cov thawj ntawm.

HSU Tshawb Nrhiav VTF-15H MK2: Kev Ua Tau
Cov neeg siv ntawm tus qub VTF-15H nyiam nws. Ob qhov subs subscriptor ntau tshaj qhov ntsuas tau los ntawm dB lossis ob, thiab ob peb lub suab qis dua thiab zoo dua hais tseg, tab sis lawv yog cov qauv zoo dua qub. Lub VTF-15H MK2 suab yeej tseem zoo tib yam li nws tus thawj ntawm. Hauv kev sib piv ntawm ib sab-ib sab, qhov txawv me ntsis ntawm qhov subs tau ntau qhov txawv ntawm lub suab tshaj hloov cov subwoofers. Subs nrog ib tug ntau tshaj 100-phaus ceeb thawj ua tus txheej txheem ces cumbersome tias lub cim xeeb ntawm lub sub nws tau sim tawm tsam twb pib ploj.
Lub VTF-15H MK2 muab ntau lub tsho xo qhov chaw uas dhau ntawm tus neeg ua tsov rog thiab xa tawm cov ntawv ntsig txog qhov tob heev. Nws 's me ntsis scary cas super sub ua tau, thiab ib super super nrog txog +3 dB ntau tso zis yog txawm scarier. Chav tsis cia li co, nws pressurizes. Koj tuaj yeem xav thiab tej zaum tseem hnov cov phab ntsa thiab qab nthab txav me ntsis. Qee tus neeg tuaj yeem hnov cov suab paj nruag hauv theem no, tab sis tsawg kawg hauv tsev ua yeeb yam hauv tsev , nws yog qhov tsim nyog vim nws muaj ntau qhov tseeb ntau dua li cas ntau lub cev qis dua tau xa tuaj.
Lub VTF-15H MK2 khaws ib qho ntawm cov qauv qub uas cov neeg nyiam heev: nws tuneability. Koj tuaj yeem ua suab nruj heev thiab punchy los ntawm ntsaws ob qhov chaw nres nkoj thiab xa Q, los yog koj tuaj yeem ua suab nrov thiab looser los ntawm kev khiav ib lossis ob qhov chaw nres nkoj thiab tej zaum tig Q qis me ntsis. Koj tsis nyob nraum nrog ib suab los yog ib hom sub.
Ib qho super lub suab uas suab me ntsis nrig thiab zoo dua txhais-ntau "suab paj nruag" -this tus thawj VTF-15H yog SVS PC13-Ultra, uas yog yuav luag ob zaug tus nqi ntawm VTF-15H MK2. Ob peb subs nrog 15-ntes tsav tsheb tau paub tias lawv lub suab txhais, tab sis qhov tseeb tias tus nqi siab tshaj 13-inch qee tsuas yog kev txhim kho qhov hloov tshiab hauv cheeb tsam no yog ib qho kev ua tiav rau HSU Research Design.

Daim duab no qhia tau hais tias lub sijhawm VTF-15H MK2 tshaj plaws nrog rau qhov sib npaug ntawm txhua qhov ntawm tsib hom: Ported Max Output (xiav kab), Port Max Max Headroom (liab), Ported Max Extension (ntsuab), Seal Max Headroom (ntshav) thiab Sealed Max Extension (txiv kab ntxwv). Cov kev ntsuas no tau tshwm sim los ntawm kev kaw-tus neeg tsav tsheb uas siv tus Audiomatica Clio 10 FW suab analyzer thiab MIC-01 ntsuas microphone. Tus Ported Max Output result tau ua kom ncav rau ntawm +3 dB, thiab lwm cov kev ntsuas raug scaled los ntawm tib tus nqi, yog li qhov txawv koj pom hauv lub teeb yog dab tsi koj yuav tau txais hauv koj chav thaum koj hloov hom. Cov kev ntsuas tau ua siv cov dav hlau hauv av nrog lub microphone rau hauv av 2 meters los ntawm tus sub thiab tau ua tiav rau 1/6 octave. Lub sub tau tso ncaj ncees, raws li nws yuav nquag siv.
Deep bass freaks zoo siab pom tias VTF-15H MK2 ploj mus rau 17 Hz hauv Ported Max Extension hom. Lus hauv no teb -10 dB teb yog 14 Hz. Cov khoom me heev muaj ntau cov ntsiab lus hauv qab 30 Hz.
Kev ntsuas CEA-2010A tau siv lub Earthworks M30 ntsuas microphone, M-Audio Mobile Pre USB interface, thiab dawb software CEA-2010 ntsuas tsim los ntawm Don Keele, nws yog ib qho niaj hnub uas khiav ntawm Wavemetrics Igor Pro scientific software pob. Cov kev ntsuas no tau tshwm sim nyob rau ntawm qhov 2 meters ntawm cov twj tso tawm kom pom, ces nce mus txog 1 meter sib npaug ntawm CEA-2010A cov lus tshaj tawm. Ob qhov kev ntsuas ntawm kev ntsuas-CEA-2010A thiab cov qauv siv qub - yog tib yam, tiam sis cov kev ntsuas, uas feem ntau lub suab thiab ntau lub tuam txhab siv, cov ntawv tshaj tawm ntawm 2-meter RMS sib npaug, uas yog -9 dB qis dua CEA- 2010A qhia. L L ib sab ntawm qhov qhia tau hais tias cov zis tau hais los ntawm subwoofer tus kheej hauv circuitry (limiter) thiab tsis yog dhau qhov CEA-2010A distortion thresholds. Qhov nruab nrab yog xam rau hauv lub pas dej. Cov zis yog ntsuas hauv peb hom uas yuav tsum xa cov zis feem ntau nrog cov subwoofer rau ntawm nws sab. Qhov no tau nyob ze rau CEA-2010 cov ntawv sau los ntsuas cov equidistant ntawm tus tsav tsheb thiab chaw nres nkoj.
Ob peb lub ntsuas ntawm cov khoom tso tawm tshiab thiab cov qub VTF-15H qauv ntawm 40 Hz ensured tias cov kev mob thaum lub sij hawm kev ntsuas tau zoo li qub. Ntawm no yog cov ntsiab lus:
CEA-2010A @ 40 Hz
VTF-15H VTF-15H MK2
Ported Max Output hom 123.2 dB 126.7 dB
Ported Max Headroom hom 121.2 dB 124.3 dB
Qhov Max Headroom hom ntu 119.2 dB 121.8 dB
VTF-15H MK2 qhov nruab nrab +3.1 dB ntau dua cov zis tshaj li daim tseem VTF-15H hauv pascos. Qhov no yog qhov yuav tsum tau muab rau ob zaug raws li cov amp loj thiab cov neeg tsav tsheb beefier.
