This was from somewhere back in the past but I believe it still applies.
The Thunderchild v2 series (generally "hi fi"/studio-like cabs, PA-style compression driver + horn for the top end), the v2 denoting the switch to a horn that has wider dispersion in the vertical plane than the originals:

Thunderchild 118 (new, also with a wider-in-the-vertical horn): 8 ohms; dimensions 30" tall x 20" wide x 14.5" deep; estimated 47-50 pounds [EDIT 2-16-2014: New estimate = 44 pounds]; 97 dB; 600 watts; -1 dB at 62 Hz with normal tuning; pluggable ports give two ported and one sealed option; top end switchable between 3.5 kHz and 18 kHz (-3 dB points). Woofer is stock Faital 18FH500.
The "Acoustic Friendly" option: Reduced-level rear-firing tweeter that adds a bit of top-end energy to the reverberant field and therefore comes a little bit closer to mimicing an actual acoustic instrument, and also lets anyone behind the cab (drummer perhaps) hear the overtones a bit better. More useful for upright bass than for electric bass. Adds about 1.5 pounds to the cab.
The Hathor series (cone midrange drivers for the top end, in a mid-chamber that is partially open on the top & back):
Hathor 1203 (new): 8 ohms; dimensions 18" tall x 14" wide x 14" deep; estimated 28 pounds [EDIT 2-16-2014: Weight = 24 pounds]; 94 dB; 500 watts; -3 dB at 62 Hz; pluggable single port; top end switchable between 3.5 kHz and 12 kHz (-3 dB points). Another switch toggles betwen smooth mids and a bit of grind in the mids. Woofer is stock Kappalite 3012LF, mid is 3" Faital.
Hathor 1544: 4 or 8 ohms; dimensions 25" tall x 18" wide x 14" deep; 34 pounds; 98 dB; 400 watts; -4 dB at 62 Hz; top end switchable between 3.5 kHz and 10 kHz (-3 dB points).
