Neat Acoustics Iota Xplorer loudspeaker Lab Report
Pair matching over the same frequency range was a little disappointing at ±1.7dB but the responsibility for that lies not with Neat's own P1-R3 bass/midrange driver – below 3kHz the pair matching is ±0.8dB – but with the rather wayward AMT tweeter. Our measured bass extension of 75Hz (–6dB re. 200Hz) may seem disappointing too, for a speaker using isobaric bass loading [see Isobaric Loading sidebar], but in practice boundary gain from the floor and wall behind will add significantly to the LF capability. Impedance is quite amplifier-friendly with a minimum modulus of 4.3ohm and minimum EPDR of 2.4ohm at 54Hz. The CSD waterfall [Graph 2] shows a clump of treble resonances between about 3kHz and 9kHz.
