Blackstar Unity U115C Elite 400-Watt 1 x 15-inch Bass Cabinet with Tweeter
The U115C is the 1 x 15 in Blackstar's Unity Elite bass cabinet range, rated at 400W RMS into 8 ohms. A single fifteen is the choice when you want weight and bloom in the low end rather than the faster attack of a stack of tens.
- 15-inch Eminence Cast Frame Driver: a rich, round bloom and stage-rumbling low end.
- 400W RMS at 8 ohms: matched to the Unity-series bass amps.
- Rear ports: enhance the bass response for greater punch and depth.
- Tweeter with three-way toggle: Off, Low or High, so you decide how much presence and harmonic sparkle sits on top of your clean and drive tones.
- speakON Combo In and Thru jacks: professional connectivity between your head and other cabinets.
- Recessed side handles and polished chrome corner protectors: road-ready convenience and protection.
- Unity-series black and smoke colour scheme: with a machined Star badge.
The three-way tweeter switch is the control that will get the most use, because it lets you set the top end to the room rather than living with a fixed amount of it.
Blackstar Unity Bass cabs provide first-rate looks and performance for your Unity-series bass amps. The U115C is the 8 ohm, 400-watt 1 x 15, built around a 15-inch Eminence Cast Frame Driver that delivers a rich, round bloom and a stage-rumbling low end.
The driver and the ports
A cast frame driver is the more rigid option compared with a stamped frame, which is why it turns up on cabinets meant to handle serious power. Behind it, rear ports on the back of the cab enhance the bass response for greater punch and depth. Together they are the reason a single fifteen can hold down a stage without a second cabinet under it.
Tweeter with three settings
An onboard tweeter runs through a three-way toggle marked Off, Low and High. It adds essential presence and harmonic sparkle to both clean and drive tones, and the three-position control means you can set the top end to suit the room rather than living with a fixed amount. Turning it off gives you a straightforward single-driver voice when that is what the song wants.
Connections and construction
A pair of dependable speakON Combo In and Thru jacks gives you pro-level connectivity between your head and other cabs, which is exactly what you want when adding a second cabinet to a rig. Side recessed handles and polished chrome corner protectors give the U115C road-ready convenience and protection, and the familiar Unity-series black and smoke colour scheme with a machined Star badge keeps it visually consistent with the rest of the range.
