A Grade A used Martin Audio XH15 is a 15-inch two-way cabinet rated 1200 W AES, 8 ohm, 55 Hz to 20 kHz, 134 dB peak, with 90 by 60 degree coverage and 2x NL4 connectors. For a B2B buyer the practical question is not whether the numbers look good but whether this box fits the rooms and rigs you actually supply, and whether the unit in front of you matches the grade. Start with the Martin Audio XH15 data, then verify the physical unit.
The XH15 is a compact point-source cabinet with enough output and low-end reach to work as a main speaker in small to mid rooms or as a fill and delay box in larger systems. Grade A means the unit is presented in the top condition band, so the buying decision turns on inspection of drivers, connectors and cabinet integrity rather than on the spec sheet. Ask OxGears for availability and current condition detail before you commit.
1. 1200 W AES and 134 dB peak put this cabinet in the high-output bracket for a single 15-inch two-way, so amplifier headroom and limiter settings matter more than raw wattage. 2. 8 ohm impedance lets you parallel fewer cabinets per amplifier channel than a 4 ohm box, which changes channel budgeting on a rental rack. 3. 90 by 60 degree coverage is a moderately wide horizontal pattern, useful for single-box coverage but not a substitute for a line array in deep rooms. 4. Grade A is a condition statement, not a measurement report, so confirm driver originality and connector condition yourself.
The listing gives a complete electrical and acoustic picture: one 15-inch woofer plus one 3-inch device, 1200 W AES power handling, 55 Hz to 20 kHz frequency range, 134 dB peak maximum SPL, 8 ohm nominal impedance, 90 degrees horizontal by 60 degrees vertical coverage, two NL4 connectors, 762 by 457 by 457 mm dimensions and 32 kg weight. Condition grade is A.
Two of those numbers do real work. The 32 kg weight and 457 mm depth make this a two-person lift that still fits on a pole mount or a small truss position, which is why cabinets in this class get used as infill and side hangs as often as mains. The 8 ohm rating is the other one: on a four-channel amplifier you can hang one cabinet per channel and keep the load simple, or pair two per channel only if the amplifier is rated for 4 ohm operation across all channels. That is a rack design question, not a speaker question, and it is the kind of thing that decides whether a rental company buys eight of these or four.
The 55 Hz lower limit means the cabinet will produce usable low end for speech, playback and light music program without a subwoofer, but it is not a subwoofer substitute for dance-floor work. Buyers assembling a full system should treat the XH15 as a top box and plan subwoofers separately; the product catalogue shows the wider inventory if you need to build a package.
Year of manufacture is listed as on request, and that is the single most consequential gap. A 15-inch woofer cone, surround and spider age with use and storage, and a cabinet built in one decade may have been reconed twice while an identical-looking cabinet from another year is untouched. Without the year you cannot reason about expected remaining life, and you cannot match cabinets within a batch by age.
Quantity available is also on request. For a distributor or integrator this matters because the XH15 is most useful in multiples: four boxes for a small venue install, eight for a rental fleet. If only one unit is available, the deployment story changes entirely and the box becomes a spare or a single-position fill rather than a system element.
Beyond those two fields, the listing does not publish measurement data. There is no impedance sweep, no SPL verification, no distortion figure and no statement of driver originality. Grade A tells you the unit has been assessed as top-band condition, and the grading logic is explained in how used professional audio is graded, but a grade is a judgement about condition, not a laboratory certificate. Treat it as a filter that gets a unit onto your shortlist, not as a replacement for your own incoming inspection.
Do not choose the XH15 if your application depends on documented service history. A venue owner writing a maintenance contract around a cabinet needs to know when drivers were last replaced and by whom, and this listing does not supply that. If that documentation is a procurement requirement, this is the wrong starting point.
Do not choose it if you need wide, even coverage across a broad floor from a single position. A 90 by 60 degree pattern is a sensible general-purpose shape, but it is still a point source: coverage falls off with distance and the vertical pattern is narrow enough that mounting height and aim become critical. Buyers who habitually solve coverage problems with more boxes rather than with array design will find a line array a better fit, and the used line array buying checklist covers that route.
Do not choose it if you need commercial terms fixed before you engage. There is no published price, warranty, lead time or MOQ on this listing. Buyers who cannot proceed without those numbers in writing at the first contact will find the enquiry process slower than they want. It is also a poor fit for anyone who needs matched, sequential cabinets for a permanent install where cosmetic and acoustic consistency across the batch is specified. Buyers weighing this cabinet against other options should browse the range of second hand PA speakers on the site to compare coverage and power handling before deciding.
Output against simplicity. A single 15-inch two-way at 134 dB peak is a lot of level from one box, and that simplicity has real value in rental stock: one cabinet, one amp channel, one cable run. The trade-off is that a point source cannot shape coverage the way an array can, so in deep or reverberant rooms you will be adding delay positions or accepting uneven coverage.
Low-end reach against subwoofer cost. The 55 Hz figure is honest for a top box and saves you a subwoofer in speech and light music work. For music program with real low-frequency content you will still buy subs, and the total system cost then includes crossovers and DSP. If you already run used pro audio equipment with a DSP platform, the XH15 slots in as a top box with a preset you control; if you do not, budget for processing.
Grade against evidence. Grade A reduces the risk of cosmetic and functional problems, and that is worth paying for relative to a lower grade. It does not remove the need to check the things a grade cannot show: whether the 15-inch driver is original, whether the 3-inch device is intact, whether both NL4 connectors are solid, and whether the cabinet has been dropped or water-damaged. The used line array buying checklist applies the same inspection logic to any cabinet, and a note on what a re-coned driver means for price is worth reading before you negotiate, because a recone changes what a cabinet is worth without changing how it looks.
Weight and handling. At 32 kg the XH15 is manageable for two people and can go on a pole or a small truss. That is a genuine operational advantage over heavier boxes in the same output class, and it is the reason cabinets like this stay in rental fleets long after newer models arrive.
Ask OxGears for availability, quantity and year of manufacture for the specific unit, then request condition detail on the drivers and connectors. The contact page is the right entry point; state your application, the number of cabinets you need and your destination port so the reply can be useful.
Before payment, plan your own incoming inspection: check both NL4 connectors for continuity and mechanical damage, look for cone and surround condition on the 15-inch driver, confirm the 3-inch device is present and undamaged, and inspect the cabinet for impact damage, water staining and correct grille fit. Confirm the impedance of the actual unit if you can, since a driver swap can change the load. If you are buying multiple units, ask for them to be checked as a set so you know whether they match.
Finally, settle the export side early: packing for a 762 by 457 by 457 mm, 32 kg cabinet, pallet configuration and documentation all affect landed cost, and shipping questions are better answered before the order than after. Buyers running a wider sourcing programme should scan the OxGears catalogue for matching tops, subs and amplifiers in the same enquiry.
