Jensen Blackbird 15-100
NEW! The official Jensen Fluid IR capture of the “Blackbird” 15/100 Signature Edition speaker, hand-crafted in 100 units only

Jensen Blackbird 15/100 Fluid IR Library
The Blackbird 15/100 is the culmination of more than 25 years of Jensen’s Research & Development. It has been conceived for those ‘tone-connoisseurs’ who seek nothing less than the best.
The Blackbird 15/100 is available only in the Raimondo Sbarbati’s Signature Edition, hand-crafted in 100 units only.
Featuring the Jensen’s exclusive “Reinforced AlNiCo” magnet design, the Blackbird 15/100 represents the ultimate Jensen voicing concept. The 15” cone grants a powerful depth in the bass range, and delivers a vocal, expressive midrange, with a delicate, yet chimey top end.
With an impressive dynamic range, paired with the sweet, progressive and musical compression typical of the best AlNiCo speakers, the Blackbird 15/100 is beautifully touch-responsive, and brilliantly suited to most applications from the cleanest, purest tones, up to all shades of punchy overdrive.
All these different personalities are brilliantly exploited by Overloud’s high-resolution capturing process, with 19 microphones in 16 positions each, mounted on a 1x15" Open Back cabinet.

Made for the supercabinet
The library is created for the TH-U Supercabinet, which allows to:
- graphically browse the IRs in the library
- blend them together
- craft new cabinet tones with the unique Multiband mode
- use the IR in the software
- export the IRs in .wav, compatible with the software IR loaders and all the major hardware modelers

FLUID IRs EXPLAINED
Fluid IRs are an advanced form of impulse responses that encapsulate more detailed sonic characteristics compared to traditional IRs. Unlike regular IRs that merely mimic a speaker's frequency response, Fluid IRs also reproduce the speaker's dynamic behavior and harmonics. This enhancement delivers a tone that is more robust, lifelike, and direct, with better management of the bass frequencies.
As of version 1.4.26, all cabinets in TH-U and all of the SuperCabinet libraries have been upgraded to include Fluid IRs, which are provided to users as a free update.
Additionally, users have the option to upload their own conventional IRs into TH-U, taking advantage of Overloud's proprietary Fluid IR technology. This technology utilizes an AI algorithm trained to transform your IRs by recreating their dynamic and harmonic responses.
