Bergantino Impulse Response – NXT212 2×12 (Closed)


The NXT212 is a precision-tuned 2×12 enclosure built with the highest quality lightweight Italian poplar plywood (with Baltic birch baffle boards).  The tone is harmonically rich, alive and present while being ultra-supportive with clean, detailed and warm lows.  The midrange is where the magic happens and your bass comes to life, with harmonics and overtones that were never audible before!  Their presence in a band mix allows your bass tone to sit perfectly while “staying in your lane”.  The NXT Neodymium magnet woofers are used for the low frequency section and  have a full and punchy low-end with a very sweet midrange. The NXT 212 features the “Reference” compression tweeter mated to a constant directivity horn, producing a very natural and extended high end.


Celestion have joined forces with Bergantino Audio Systems to faithfully capture in digital form the tones of their superb NXT (X-Treme Neo) series of bass guitar cabinets. Using the same painstaking recording methods we applied to the Celestion bass speaker IRs, our experienced sound engineers have perfectly captured the unique tones of these eight cabinets:

  • NXT112: Closed back 1×12 cabinet with tweeter
  • ENXT112: Closed back 1×12 cabinet without tweeter
  • NXT210: Closed back 2×10 cabinet with tweeter
  • NXV210: Closed back 2×10 cabinet without tweeter
  • NXT212: Closed back 1×12 cabinet with tweeter
  • NXV212: Closed back 1×12 cabinet without tweeter
  • NXT322 Combined 2×10 + 1×12 bass stack with tweeter
  • NXV322 Combined 2×10 + 1×12 bass stack without tweeter

Every Bergantino cabinet impulse response has been sampled using the same pro-quality microphones: a Sennheiser MD421, Neumann U47 FET and AKG D112 – each in six different positions for additional tonal variety, creating an extensive IR library for each speaker cab. Also included is a room mic recording using a Neumann TLM 107.

Each tweeter-loaded cab includes an additional high frequency IR (recorded using a Neumann KM84), which can be used on its own or mixed with one of the other microphones to add an extra bit of ‘zing’ to the top-end.

We’ve also included a selection of extra mic mixes for you to experiment with, including:

  • D112+KM84
  • U47+KM84
  • MD421+KM84
  • D112+MD421+KM84
  • U47+MD421+KM84
  • U47+D112+KM84
  • All mics
  • All mics+Room Stereo
  • All mics+Room Mono

Also included in each cabinet option are Celestion’s unique ‘Playing Style’ IRs which have been optimised for a range of different playing methods: Finger basic, Finger warmth detail, Plectrum (Pick) basic, Plectrum (Pick) aggressive and Slap.

These Bergantino cabinet impulse responses are all delivered in .WAV format for maximum compatibility with a wide range of leading DAWs, amp modellers and profilers.
