No, and I wouldn't recommend it if there were. The best match is a high efficiency woofer that's only about 10dB lower than the tweeter, just enough for passive EQ of the power response using the R1/R2/C1 network. A woofer that is less efficient than that - needing more than 12-14dB attenuation - is probably not a good match for this kind of system. I've calculated values well above and below what I'd actually recommend using.
