An inexpensive option might be the Eminence 15269 (Martin 1844). About 101dB/2.83V/1M (two drivers).Driver Properties
Name: 15269
Type: Standard one-way driver
Company: Eminence Speaker LLC
Comment: Martin #1844
No. of Drivers = 2
Mounting = Standard
Wiring = Parallel
Fs = 23.4 Hz
Qms = 11.63
Vas = 359.4 liters
Cms = 0.35 mm/N
Mms = 132.1 g
Rms = 1.67 kg/s
Xmax = 9.1 mm
Xmech = 15 mm
P-Dia = 329 mm
Sd = 850 sq.cm
P-Vd = 0.774 liters
Qes = 0.35
Re = 6.21 ohms
Le = 2.5 mH
Z = 8 ohms
BL = 18.56 Tm
Pe = 300 watts
Qts = 0.34
no = 1.269 %
1-W SPL = 93.18 dB
2.83-V SPL = 94.28 dB
-----------------------------------------
Box Properties
Name:
Type: Closed Box
Shape: Prism, square (optimum)
Vb = 11.19 cu.ft
Qtc = 0.5
QL = 14.54
F3 = 57.9 Hz
Fill = heavy
********************************************
This would have a Qtc=0.5 and a 40hz resonance. With a 12dB/oct high-pass with a Q=1 at 40hz this would have a LR24 transfer function at 40hz.
*************************************************
Same drivers in 7 cu ft would have a Qtc=0.577 and a 47hz resonance. With a 47hz Q=0.867 12dB high-pass the transfer function would be LR24 at 47hz.
**************************************
Same drivers in 4 cu ft would have a Qtc=0.707 and a 60hz resonance. With a 60hz Q=0.707 12dB high-pass the transfer function would be LR24 at 60hz.
