Recoil CRX-PRO Review: 5-Way Electronic Crossover, 30 Hz to 20 kHz
The Recoil CRX-PRO is a 12 V electronic crossover that splits a signal into low, low-mid, high-mid and high bands plus a pass-through output, with crossover points adjustable from 30 Hz to 20 kHz. Its Indian MRP is ₹11,000. It suits an active system built from separate amplifiers, where you want the frequency splits made in one dedicated box. You can see it on our Recoil CRX-PRO product page.
Key takeaways
Four band outputs (low, low-mid, high-mid, high) plus a pass-through output are listed, with adjustable crossover points across 30 Hz to 20 kHz.
A subsonic filter (bypass, 40, 60 or 80 Hz), a +10 dB bass boost at 40 Hz and a 0°/180° phase switch are listed.
The pages give no slopes, per-band ranges or RCA jack count.
It is a crossover, not a DSP: time alignment and equalisation are not listed.

The figures come from our store listing and Recoil's CRX-PRO page, which agree apart from the label on the 0.01% figure. Recoil's page adds that no DSP programming is needed and that set-up takes 15 minutes; that is promotional copy. It does not give the crossover slope, input impedance, output level, gain controls, supply range, current draw, RCA jack count or any per-band frequency range.
How the bands are described
The listing calls the CRX-PRO a 5-way crossover and describes four band outputs, low, low-mid, high-mid and high, plus a pass-through output. Crossover points are adjustable across 30 Hz to 20 kHz. That is the full extent of what the pages say about the bands. They do not say which frequencies each band covers or how many points can be set, so we describe none of it.
In principle, four band outputs could serve a four-way active layout, for example subwoofer, midbass, midrange and tweeter, with a separate amplifier channel behind each. Because the pages give no per-band ranges, confirm them with Recoil before you buy, to see whether it suits your speakers. The pass-through output is listed without detail; the term usually means an unfiltered copy of the input, but the pages do not say.
Subsonic filter, bass boost and phase
A subsonic filter removes the lowest frequencies, below a set point. The listing offers bypass, 40, 60 or 80 Hz. In general, it keeps energy that a subwoofer cannot usefully reproduce away from the amplifier, and it matters most with ported enclosures. VA3 Car Studio builds custom subwoofer enclosures if you need a box made to a published volume.
The bass boost is listed as +10 dB at 40 Hz, without saying whether it is fixed, switchable or variable. In power terms, +10 dB is a tenfold increase at that frequency, so use it sparingly and check that your amplifier has headroom. The 0°/180° phase switch flips polarity, which helps when a subwoofer and the door speakers cancel each other near the crossover point. The listing does not say which outputs the switch affects.
Inputs, connections and power
The listing gives an input selector (SUB/LOW or FRONT/REAR), colour-coded RCA jacks and a remote turn-on lead, on a 12 V unit. Recoil's page does not explain the selector or count the jacks, and the pages do not say whether the turn-on lead is an input or an output, so ask us before wiring it.
The listing names RCA jacks and no speaker-level inputs, so a factory radio without pre-outs needs a converter in front. Our posts on the Recoil PLC44PRO and the Recoil RLOC46-LC cover two Recoil converters. If the source already has pre-outs, none is needed.
Crossover or DSP?
A crossover divides the frequency range between amplifiers and speakers. The Recoil P610-PRO listing, by comparison, names time alignment, parametric EQ, high- and low-pass crossovers, mixing, phase and level in one unit, while the CRX-PRO listing names neither time alignment nor equalisation. If your car needs delay or equalisation to sound right, a DSP is the tool; our guide to setting up a DSP explains those steps, and The Need for DSP in Car Audio Systems explains why a cabin needs them.
For tone shaping in a separate box, see our post on the Recoil REQ7 equaliser.
What owners and reviewers say about the Recoil CRX-PRO
When we checked in October 2026, we found no independent review, owner thread or retailer review page for the CRX-PRO, and Recoil's own page shows no customer reviews. Some review sites and forums could not be read, so a review may exist that we missed.
The only description is Recoil's promotional page, so we make no claims about its noise, sound or build beyond the published figures. If you run a CRX-PRO, tell us how the splits and the subsonic filter worked in your car.
Who should buy it, and who shouldn't
Choose the CRX-PRO if you are building an active system on separate amplifiers, have RCA sources, and want adjustable splits, a subsonic filter and a phase switch in one box.
Look elsewhere if you need time alignment or equalisation, if your source has only speaker-level outputs, or if you need slopes and per-band ranges confirmed first, since none of the pages we read gives them.
Installation notes for Indian cars
The aluminium chassis measures 224 x 116 x 30 mm, a low unit that may fit behind a panel or under a seat, so measure first. Give it some air, keep it dry, and fix it down so rough roads cannot shake it loose. Route RCA leads away from power cables to limit noise.
The pages give no supply range or current draw, so confirm both with Recoil before wiring. VA3 Car Studio in Ghaziabad offers professional installation, and we also make speaker pods and door baffles for an active front stage.
Price and where to buy
The Recoil CRX-PRO has an Indian MRP of ₹11,000. We often sell below MRP, so check the current offer on the CRX-PRO product page. Recoil's CRX-PRO page states a 12-month warranty against defects, and its general warranty terms describe a US return process, so confirm India terms with us.
The bottom line
The CRX-PRO is a plainly described active crossover: four band outputs plus a pass-through, 30 Hz to 20 kHz adjustment, a subsonic filter, a bass boost and a phase switch. The pages leave out slopes, per-band ranges and the jack count, and we found no independent reviews, so confirm those with Recoil before you plan a system around it.
Recoil CRX-PRO FAQ
What does the Recoil CRX-PRO do?
It splits an RCA signal into low, low-mid, high-mid and high band outputs plus a pass-through, with crossover points adjustable from 30 Hz to 20 kHz, so each amplifier channel gets its own frequency range.
Does the CRX-PRO replace a DSP?
No. The listing names crossover points, a subsonic filter, a bass boost and a phase switch, not time alignment or equalisation. A DSP such as the Recoil P610-PRO lists those functions.
Can the CRX-PRO connect to a factory radio?
Only through a converter if the radio has no pre-outs, because the listing names RCA jacks and no speaker-level inputs. We list Recoil converters such as the PLC44PRO and RLOC46-LC.
What is the subsonic filter on the CRX-PRO for?
It removes the lowest frequencies below a set point of 40, 60 or 80 Hz, or can be bypassed. It is typically used to protect a subwoofer and its amplifier, especially with a ported enclosure.
