The comparison I wish I had framed sooner
I am an office administrator for a 120-person company. I manage AV and facilities purchasing—roughly $85,000 annually across 12 vendors. I report to both operations and finance, so I care about three things: whether the gear solves the problem, whether the invoice will clear, and whether I will have to explain a surprise line item six months later.
When I took over AV purchasing in 2020, the default question was: which new box do we buy? In our 2024 vendor consolidation project, the better question became: which path gives us the most reliable result per dollar? That shift is why I now compare used Electro-Voice ZXA5V powered speakers against new Electro-Voice ELX118P-120V powered subwoofers before I approve either. They are not the same product category—one is a full-range top, one is a sub—but they often compete for the same budget line when a room needs better sound.
I also get requests for a megaphone loudspeaker customized for outdoor use, an Optoma BM21 loudspeaker, or a TV sound bar and subwoofer. Those can be valid in narrow situations. They are rarely the right answer for a commercial install that needs coverage, headroom, and serviceability. Here is how I compare the options across the dimensions that actually matter in procurement.
Dimension 1: Total cost and hidden risk
A new Electro-Voice ELX118P-120V powered subwoofer has a boring, predictable cost story. You get a manufacturer warranty, a proper invoice, and a spec sheet you can hand to finance. As of January 2025, Electro-Voice published spec sheets list the ELX118P as an 18-inch powered subwoofer with onboard crossover. That means fewer external processing boxes and less rack space. For a small venue that just needs low end under existing tops, it is often the lower-risk purchase.
A used Electro-Voice ZXA5V powered speaker has a different cost story. The entry price can be attractive, but the true cost includes inspection time, shipping risk, replacement drivers, and the possibility that you are buying someone else's road-worn problem. I learned that the hard way. I knew I should get a written condition report and a driver photo, but thought 'what are the odds?' Well, the odds caught up when the used ZXA5 arrived with a non-OEM high-frequency driver. It worked for two weeks, then started distorting during a staff event (which, honestly, felt like a personal attack from the universe).
We also did not have a formal used-gear inspection process. The third time we ordered the wrong quantity or condition, I finally created a verification checklist. Should have done it after the first time. Now any used speaker must pass four checks: impedance sweep, pink-noise test, cabinet inspection, and invoice matching. That process gap cost us roughly $400 in a rushed replacement, plus the internal credibility hit.
Comparison conclusion: If your team cannot test used gear and handle a possible repair, the new ELX118P-120V is usually the better total-cost decision. If you have a technical integrator or an in-house tech who can inspect and document condition, a used ZXA5V can deliver more premium build quality per dollar. Just do not let the low sticker price hide the risk. In plain search terms, I was comparing a used electro voice zxa5v powered speaker against an electro-voice elx118p-120v powered subwoofer.
Dimension 2: Performance fit—what problem are you solving?
This is where the comparison gets counterintuitive. A used ZXA5V is a 15-inch two-way powered loudspeaker, now discontinued. It is designed for full-range program audio, vocal reinforcement, and stage monitoring. An ELX118P-120V is a subwoofer. It extends low frequency. If your system lacks bass, a ZXA5V will not replace a sub. If your system lacks vocal clarity, a subwoofer will not fix it.
Never expected a used ZXA5 to outperform a new budget sub in vocal clarity for a 150-seat room. Turns out the full-range driver and horn pattern matter more than raw wattage for speech. For corporate presentations, worship services, and theater, a clean top box often does more for perceived quality than adding more low end. For DJs, live bands, and dance floors, the opposite is true: without a sub, the system feels thin no matter how good the top is.
That is also why I push back on some requests. A customized megaphone loudspeaker is excellent for outdoor crowd control, factory floor announcements, or emergency messaging. It is not a music system. An Optoma BM21 loudspeaker might be fine for a single small huddle room where the projector is the main event. A TV sound bar and subwoofer can work in a basic conference room if the room is small, the ceiling is low, and no one expects distributed audio. But in a gym, sanctuary, or multi-zone install, those consumer-adjacent options rarely provide the coverage pattern, mounting flexibility, or 70V/100V support that commercial work demands.
Comparison conclusion: Buy the ELX118P-120V if low-frequency extension is the missing piece. Buy a used ZXA5V if you need clear full-range output and can verify condition. Do not buy either if the real need is a customized megaphone loudspeaker, an Optoma BM21 loudspeaker, or a TV sound bar and subwoofer for a job they were not designed to handle.
Dimension 3: Integration, serviceability, and the industry evolution
What was best practice in 2020 may not apply in 2025. Used premium audio gear is more viable now because measurement tools are cheaper and online communities share service manuals, replacement parts, and repair tips. The fundamentals have not changed—coverage, headroom, reliability—but the execution has transformed. A used ZXA5V that would have been a blind gamble five years ago can now be validated with a $100 measurement mic and a laptop.
At the same time, new gear has evolved. The ELX118P-120V is self-powered and includes onboard crossover, so it integrates quickly with modern mixers and powered tops. It also comes with warranty support. For a system integrator who needs repeatable deployments across multiple sites, that predictability matters. For an admin buyer like me, it means fewer calls to explain why a used box failed during a client event.
I have mixed feelings about used pro audio. On one hand, the value can be excellent. On the other, one bad driver can eat the savings and make the AV budget look careless. I compromise with a primary plus backup approach: new powered subs for revenue-critical rooms, inspected used Electro-Voice tops for less critical spaces where a spare can be swapped in.
Per Electro-Voice published spec sheets (accessed January 2025), the ELX118P-120V is an 18-inch powered subwoofer with onboard crossover, while the ZXA5V is a discontinued 15-inch two-way powered loudspeaker. Verify current listings, firmware revisions, and condition reports before purchase. Used-market pricing varies widely; as of January 2025, I have seen used ZXA5V listings from roughly $450 to $850 depending on condition and accessories. Check Reverb, eBay, or a trusted dealer for current pricing, because rates may have changed.
Comparison conclusion: New ELX118P-120V wins on integration and warranty. Used ZXA5V wins on performance-per-dollar if your team can inspect, test, and service it. The industry has not made used gear obsolete; it has made verification more accessible.
What I would choose by scenario
Here is the short version I give to operations and finance when they ask why one request is approved and another is not.
- Need low end for a 100-250 capacity room: New Electro-Voice ELX118P-120V powered subwoofer, usually paired with existing full-range tops. Predictable warranty and onboard crossover reduce integration risk.
- Need clear speech or stage monitoring: Used Electro-Voice ZXA5V powered speaker, but only with a written condition report, impedance sweep, and return option. Pair with a sub later if music playback matters.
- Need outdoor crowd control: Customized megaphone loudspeaker. Do not try to cover a parking lot with a soundbar.
- Need a basic huddle room: Optoma BM21 loudspeaker or TV sound bar and subwoofer may be acceptable if the room is small and no distributed audio is required.
- Need a commercial gym, sanctuary, or multi-zone system: Skip consumer options. Use commercial loudspeakers and subwoofers designed for the coverage, mounting, and power requirements.
The comparison is not really used versus new, or Electro-Voice versus everything else. It is fit versus convenience. A new ELX118P-120V is convenient and lower risk. A used ZXA5V is a calculated bet that can pay off. A customized megaphone loudspeaker, an Optoma BM21 loudspeaker, or a TV sound bar and subwoofer are narrow tools that should stay in their lane. Match the tool to the room, document the condition, and keep a backup. That is how I keep operations happy, finance calm, and the sound system working when it matters.
