Quick disclaimer - I'm new to transmission line design - I intend to buy Martin J. King's mathcad worksheets, but I thought I'd come here for advice whether I had the sheets downloaded or not...
Would this parts express buyout be suitable for a transmission line? And what would the output look like below Fs (advertised 52hz)?
Power Handling (RMS) 50 Watts
Power Handling (max) 100 Watts
Impedance 4 ohms
Frequency Response 50 to 6,000 Hz
Sensitivity 88.3 dB 2.83V/1m
Voice Coil Diameter 1"
Resonant Frequency (Fs) 52 Hz
DC Resistance (Re) 3.37 ohms
Voice Coil Inductance (Le) 0.48 mH
Mechanical Q (Qms) 2.99
Electromagnetic Q (Qes) 1.40
Total Q (Qts) 0.95
Compliance Equivalent Volume (Vas) 0.65 ft.³
Maximum Linear Excursion (Xmax) 3.5 mm
Another really cheap option would be the MCM 55-3231 (8" with a claimed Fs 28.8hz)
Resonance Frequency Fs: 28.8Hz
DC Resistance Re: 3.4Ohm
Mechanical Q Factor Qms: 3.4
Electrical Q Factor Qes: 0.5226
Total Q Factor Qts: 0.4529
Equivalent Cas air load Vas: 98.26 L
Surface Area of Cone Sd: 0.0216 m2
Efficiency Bandwidth Product EBP 55.1
Voice Coil Over Hang X-max 3.5 mm
The theme here is cheap drivers. If the geometry works, I'd like to stack perhaps 8 drivers or so per side in a stereo transmission-line-array (or would it be a transmission line line array?
