Recalculare boxa
« on: August 28, 2009, 06:11:44 PM »
Cu ceva timp in urma am facut niste boxe si deoarece nu am gasit parametri Thiele Small pentru respectivul am aproximat parametri luand ca referinta un alt difuzor( aceeasi marca si de aceeasi dimensiuni si putere).
De curand am gasit parametri si pentru difuzorul cautat si voriam sa verific cat de aproape am fost in calculele facute fatta de cele facute cu parametri corespunzatori .
Parametri sunt :
Music power Pz / W 150
Power rating Pn / W 120
Impedance Ω 8
Free air resonance fs / Hz 28
Max. frequency range  f / Hz 30-2500
Rec. crossover freq. (fmax.) fx / Hz 1500
SPL (1W/1m) Spl / dB 88
Voice coil diameter ∅ / inch 2,5
Magnet weight Oz 50
RDC DC resistance RDC / Ω 7,0
Eff. cone area Sd / cm2 502,7
Mech. Q factor Qms 9,62
Electr. Q factor Qes 0,54
Total Q factor  Qts 0,51
Equivalent volume VAS / l 94,55
Moving mass Mms / g 121,82
Mech. resistance  Rms / kg/s 2,42
Suspension compl. Cms / mm/N 0,27
Force factor Tm 15,97
Voice coil induct. L / mH 7,20
Dimension ∅ / mm 327
Mounting cutout ∅ / mm 280
Nu-mi dau seama care e Xmax ( cursa maxima) ???

Cred ca nu e trecut .
Am observat ca daca calculezi o boxa dupa parametri Thiele Small boxa iese prea mare .

This taught me many things. I think that if anyone had read it, I'm going to have to know what innovative new ideas were legally sleep.

I was skeptical about this, and fortunately I had the chance to read something I did not understand yet.
