Vixen Horns VXH2311B Dual Trumpet Train Horn Kit Review (2026)

Methodology

This review aggregates publicly available information from manufacturer specifications, retailer listings, and verified user reviews. We do not perform hands-on testing.

Quick verdict

The Vixen Horns VXH2311B is a $30 compact dual-trumpet horn kit, not a true train horn — and once you accept that framing, it’s a reasonable buy. You get two metal trumpets, a small maintenance-free 12V direct-drive compressor, a relay, hose, and hardware in one box, backed by a 12-month warranty. What you don’t get is any published decibel or PSI rating from Vixen. We rate it 3.3/5: a cheap, easy upgrade over a weak stock horn for motorcycles and small vehicles, but a letdown if you’re expecting locomotive-grade sound.

What it is

The VXH2311B is the black version of Vixen Horns’ entry-level dual-trumpet kit. Unlike the big tank-fed systems that dominate our Vixen Horns review hub, this is a tankless, direct-drive setup: press the horn button and a compact 12V compressor pushes air straight through a 3/8” hose into two metal trumpets, with no air tank in between. Per Vixen’s product page, the trumpets measure 11-1/2” and 9” long with 3-1/2” bell diameters, and the whole kit weighs roughly 2.8 lb according to the listing data.

That format defines the buyer. This is for someone with a motorcycle, car, SUV, or pickup with limited mounting space who wants a noticeably louder, deeper blast than the stock horn without plumbing an onboard-air system. Vixen sells two siblings if the base kit isn’t quite right: the VXH2311DB adds a second compressor for more airflow, and the VXH2311C is the same kit in chrome. If you’re deciding between this style and a real tank-fed system, our tankless train horns guide walks through the trade-offs.

Vixen Horns is a US-market budget brand sold primarily through Amazon, Walmart, and its own webstore, sitting a tier below Kleinn and HornBlasters on price and a tier above no-name imports on support — it maintains a real warranty program and publishes installation instructions for its kits. The VXH2311B is also sold on Amazon under ASIN B06XRJDVR9, though the listing itself is light on hard numbers. In editorial terms, we’d call this kit’s spec sheet the thinnest in Vixen’s lineup: the larger tank-fed Vixen systems at least publish PSI and tank volumes, while this one leans entirely on “Super Loud” marketing language.

A note on that loudness figure: Vixen’s own website publishes no decibel number for this kit at all. The 129 dB claim appears only in retailer listings, so treat it as marketing rather than a measured spec. Our guide on advertised vs real-world decibels explains why undocumented dB numbers routinely overstate what you’ll hear.

What’s in the box

Per Vixen’s product page, the kit includes:

• Dual-trumpet metal air horn (black)
• 12V heavy-duty maintenance-free air compressor
• 4-pin 12V/30A relay
• 3/8” OD air hose
• Mounting hardware
• Installation instructions

Note that the kit contents list includes no wiring beyond the relay — plan on buying a horn button or splicing into your existing horn circuit, plus appropriate gauge wire and a fuse.

Pros

• Very cheap: $30.07 at Vixen’s site as of August 2026, down from a $40.95 list price
• All-metal trumpets at a price point where most rivals use ABS plastic
• Genuinely compact — no air tank, so it fits motorcycles and tight engine bays
• Complete one-box kit: compressor, relay, hose, and mounting hardware included
• 12-month parts warranty plus Vixen’s lifetime tech support, both stated on the official site

Cons

• Vixen publishes no dB or PSI rating anywhere — “Super Loud” is the only official loudness claim
• The 129 dB figure in retailer listings doesn’t appear anywhere on Vixen’s own site
• Direct-drive compressor can’t match tank-fed kits for volume, tone, or blast duration
• No chord frequency (Hz) data published for comparing tone on paper

Alternatives

• Wolo Bad Boy 419 — the best-known compact tankless air horn, with an actual published spec sheet from an established US brand; usually costs more. See our Wolo Bad Boy 419 review.
• Kleinn HK2 — a real dual-trumpet train horn kit with a tank-fed air system; several times the price, but it delivers the loudness this class of tankless kit can’t. See our Kleinn HK2 review.
• Vixen Horns VXH3318B — Vixen’s all-metal 3-trumpet horn cluster for buyers who already run onboard air and want genuine train-horn output. See our VXH3318B review.

Install / compatibility notes

The VXH2311B works on any vehicle with a 12V electrical system — Vixen lists trucks, cars, motorcycles, semis, pickups, RVs, and SUVs. Because there’s no tank or pressure switch, installation is simpler than a full train horn kit:

1. Mount the trumpets on the roof or under the hood, angled slightly downward so rainwater drains out of the bells.
2. Mount the compressor close to the trumpets in a dry, ventilated spot and connect it with the supplied 3/8” hose.
3. Wire the compressor through the included 4-pin 30A relay, triggered either by your stock horn circuit or a dedicated button — our relay wiring guide shows both layouts.

Two cautions. First, direct-drive kits sound their best only while the compressor is spinning at full speed, so expect a brief ramp-up rather than an instant full-volume blast — that’s inherent to the format, as our train horn vs electric horn comparison explains. Second, exposed motorcycle mounting means more water and vibration; mount the compressor as sheltered as possible, since moisture is the usual killer of these small units.

If you find the output underwhelming after install, the honest fix isn’t tweaking this kit — it’s stepping up to a tank-fed system. There is no pressure adjustment on a direct-drive compressor, so what you hear on day one is what you get.
