#37 RCF ART 708-A MK4: $525.00 Discontinued eBay
Newer model: the RCF ART 708-A MK5, ranked higher, rated 3.4/5, released Jan 2024. See every RCF ART 7 generation.
Pros: A discontinued, affordable powered 8 inch PA speaker with a broad horn and simple setup. The 10.4kg cabinet combines 127dB claimed peak output, a broad horn and RCF’s FiRPHASE processing in a straightforward, affordable package for an 8-inch box. Measured bass extension of 75Hz (-3dB).
Cons: The low-quality vendor measurement is truncated and cannot produce a reliable preference score. This discontinued MK4 offers little reason to choose it over the newer RCF ART 708-A MK5 unless the used price is substantially lower.

Frequency Response
How the RCF ART 708-A MK4 measures across the audible range. A flatter listening window (the sound arriving straight at you) is more neutral: peaks sound forward or harsh, dips sound recessed. The estimated in-room response adds what a typical room does, and there a gentle, even tilt down toward the treble is ideal. Both curves are shifted so their 300 Hz to 3 kHz average sits at 0 dB.
Measurement data: spinorama.org, measured by the manufacturer.
EQ for a Neutral Response
Flattens the measured listening window from the RCF ART 708-A MK4's own bass extension up to 16 kHz. Set a preamp of -1.2 dB, then add these filters to any parametric equalizer in the signal path: the speaker's app or DSP if it has parametric EQ, a miniDSP, Equalizer APO or Wavelet. Boosts are kept to 3 dB, and EQ cannot fix how evenly the speaker spreads sound off-axis, which is why some speakers gain more than others. Calculated by Speaker Ranking from the spinorama measurements above.
| Filter | Frequency | Gain | Q |
|---|---|---|---|
| Peak | 98 Hz | -3.5 dB | 0.92 |
| Peak | 405 Hz | -0.9 dB | 1.69 |
| Peak | 2,380 Hz | +1.1 dB | 1.18 |
