Tjo !
Blev lite inspirerad av Matsj och hans basreflexfråga så jag provar och slänga ut en jag också 
Tänkte mig dock spela upp till ca 200Hz med följande element, basreflex eller slutet.
Nominal Impedance 8 Ohm
Lowest Resonance Frequency (Fo) 28 Hz
Frequency Range 28-2000 Hz
Rated Input Power 200 Watt
Maximum Input Power 500 Watt
Sound Pressure Level 97.5 dB/W (1m)
Total Magnetic Flux 277.000 Mx
Magnetic Flux Density 12.400 G
Highest Recommended Crossover 1.200 Hz
Recommended Enclosure 113 - 304 liter
Effective Piston Diameter 335,0 mm
Baffle Opening 352,0 mm
Mounting Dimensions 370,0 mm
Weight 11 kg
Dimensions (diameter x depth) 400 x 167 mm
Theile-Small Parameters TL-1601b
sd - Piston Area 0,0881 Sq M
Revc - DV Voice Coil Resistance 7 Ohm
Levc - Voice Coil Inductance 1kHz (mH) 1,7
BL - Flux Density (TM) 20,5
Vas - Equivalent Acoustic Volume (Liter) 304 liter
Cms - Mechanical Suspension Compliance (x 10-4 m/N) 2761
Mms - Mechanical Mass of Cone and Free Air Load 117 g
Mmd 86 g
Fs - Free Air Resonance Frequency 28 Hz
Qms - Mechanical Q Factor 6,8
Qes - Electrical Q Factor 0,32
Qts - Total Q factor 0,31
Xmax - Max Linear Peak Excursion (O-P) 8,0 mm
Pmax - RMS Thermal power Limit 500 Watt
no - Relative Efficiency 2.00%
Vd (cm²) 705
Max. Excursion Before Damage (P-P) 36,0 mm |
