Thunderchild 115v3, Switchable between 4 and 8 ohms; Dimensions 24.5" tall x 18" wide x 14" deep; 37 pounds; 98 dB; 500 watts; -4 dB at 62 Hz with normal tuning; three pluggable ports give three ported and one sealed option (for adapting to different room acoustic situations); top end switchable between 3.5 kHz and 18 kHz (-3 dB points). Another switch toggles between smooth mids and a bit of grindy in the upper mids. Woofer is a custom 4 ohm Kappalite variant with more output in the upper mids than the stock Kappalites. Price: $1050 + shipping.
Like the Thunderchild 112, the Thunderchild 115 is reminiscent of a high quality light PA cab but is rugged enough for electric bass. The Thunderchild 115 uses a more rugged compression driver than the Thunderchild 112. One of my Thunderchild 115 customers, an award-winning studio designer, is using a pair in his living room for home audio.
The "4/8 ohm" switch works like this: The woofer starts out as a "high 4 ohms woofer" and the switch adds just enough series resistance so that the load the amplifier sees becomes, in effect, an "8 ohms nominal" load. The actual difference in impedance is much less than these numbers imply. When engaged, the switch reduces the efficiency by about 1 dB and reduces the voltage sensitivity by about 2 dB, but in turn you can safely parallel the cab with another 8 ohm cab for a loud gig. Even with those reductions, In 8-ohm mode, the Thunderchild 115v3's woofer is about as loud as a stock Kappalite 3015 (non-LF), which is one of the loudest 15-inch neo-magnet woofers out there. The switch can be omitted if desired, reducing the price by $50 and reducing the weight by one pound.
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 mimicking 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 and $100 to the price.
AudioKinesis bass cabs are hand-built to order; we're a small company so we don't have stocks of all these various bass cabs ready to ship. Please call or e-mail for delivery time estimates.
