Quick answer
A used Martin Audio T1215 is a Grade A second-hand line array element with one 12-inch LF driver on a 3-inch voice coil and three 1-inch HF drivers on 1.4-inch voice coils, rated AES 400W and 1600W peak at 8 ohms. Buy it if your room and array design already fit a fixed 15-degree vertical splay with 60, 75 or 90 degree horizontal coverage; skip it if you need variable vertical control. Confirm year of manufacture, quantity and driver history with OxGears before you commit.
Key takeaways
1. The vertical coverage is fixed at 15 degrees, so array length and trim height are decided by the cabinet count, not by adjustable hardware.
2. Three horizontal pattern options on one box give rental fleets flexibility without stocking three separate models.
3. Grade A is a condition statement about the unit as offered, not a guarantee of original drivers, so ask for driver and rigging detail.
4. At 31 kg per cabinet and 650 x 369 x 452 mm, freight and case planning matter as much as the acoustics.
What the listing data says
Start with the numbers that are actually published. The Martin Audio T1215 is listed as a line array element with one 12-inch LF driver carrying a 3-inch voice coil and three 1-inch HF compression drivers with 1.4-inch voice coils. Power handling is stated as AES 400W with 1600W peak, and nominal impedance is 8 ohms. Frequency range is 65Hz to 18kHz at plus or minus 3dB. Maximum SPL is given as 128dB continuous and 134dB peak.
Coverage is the defining figure. Horizontal is selectable at 60, 75 or 90 degrees, and vertical is fixed at 15 degrees. Rigging is integral with a fixed 15-degree angle and pole-mount fittings are present. Physical data is 650 x 369 x 452 mm and 31 kg, or 68.34 lbs.
The listing carries condition grade A, which on this site means the top of the three-tier grading scale described in how used professional audio is graded. Year of manufacture and quantity available are both marked as on request rather than stated, so neither can be assumed.
What the datasheet does not tell you
Three things follow from the spec combination that a plain spec table will not spell out. First, a fixed 15-degree vertical angle means the array is designed by counting boxes. Two cabinets give roughly 30 degrees of vertical coverage, three give roughly 45, and so on, before any electronic shading. That is fine for a stacked or short flown array over a stage or a mid-size room, but it removes the option of tightening the vertical pattern for a long, narrow throw. If your room needs 6 to 10 degrees of vertical per box, this cabinet is the wrong building block.
Second, three HF drivers sharing one 1.4-inch voice coil format across a 60 to 90 degree horizontal window means HF output per box is spread rather than concentrated. In practice that supports the 128dB continuous figure across a wide horizontal field, which suits coverage-led installs and rental jobs where even horizontal dispersion matters more than maximum on-axis punch at distance.
Third, 31 kg with integral rigging and a fixed angle is a rigging-planning number. It tells you how many cabinets a bumper and motor can take and how many fit a truck or a flight case. It does not tell you whether the rigging hardware on this specific unit has been inspected, whether bumpers and link bars are included, or whether the cabinets have been flown or ground-stacked in their previous life. Grade A describes the unit as offered; it does not by itself document rigging history.
Who should not choose this
Do not choose the T1215 if your design depends on variable vertical splay per cabinet. Rental companies quoting rooms where the array must be electronically or mechanically steered to a narrow vertical window will fight the fixed 15-degree angle on every job, and no condition grade fixes that.
Do not choose it if you are buying a single cabinet as a standalone full-range box for a small venue. The 65Hz low-frequency limit means it expects subwoofer support below that, and a lone element with 15 degrees of vertical coverage will not behave like a point-source speaker. Buyers wanting one-box coverage should look at full-range cabinets in the used pro audio equipment range instead.
Do not choose it if you cannot get driver and rigging detail before payment. A Grade A cabinet with non-original HF diaphragms is a different commercial proposition from one with original drivers, and the materials here do not state which you are getting.
Trade-offs to weigh
Flexibility versus predictability. Three horizontal patterns in one box is genuinely useful for a distributor or rental fleet serving varied rooms, because one stock item covers 60, 75 and 90 degree jobs. The cost is that the vertical behaviour is not adjustable, so the same box that covers a wide room horizontally still commits you to 15 degrees vertically.
Output versus box count. With 128dB continuous and 134dB peak per cabinet, array length is the lever for SPL. That is normal for line array work, but it means the purchase decision is really a decision about how many cabinets you need, and quantity available is listed as on request rather than stated.
Weight versus handling. At 31 kg the cabinet is manageable for two people and reasonable for truck packing, but integral rigging plus fixed angle means you should confirm what rigging accessories travel with the units. Accessories are not listed in the materials.
Condition grade versus documentation. Grade A is the strongest grade on offer here, and the used line array buying checklist logic still applies: grade describes condition as offered, while driver originality, HF diaphragm status and rigging inspection are separate questions you must ask. Year of manufacture is also on request, which matters because cabinet age affects both driver condition and how the rigging hardware has aged.
Next step before you pay
Ask OxGears four things in one message. Confirm the year of manufacture for the units on offer. Confirm how many cabinets are available so you can size the array. Ask whether the LF driver and the three HF drivers are original or have been re-coned or re-diaphragmed, and whether any diaphragm replacement is documented. Ask what rigging hardware, bumpers, link bars and pole-mount fittings are included with each cabinet, and whether flight cases are part of the deal.
Then confirm commercial terms. Price, MOQ, lead time and warranty are not stated in the materials, so treat them as open questions rather than assumptions, and ask for them explicitly along with the Incoterm you want, such as FOB. For export buyers in the Middle East, Southeast Asia, Africa, Europe and South America, freight class and packing should be agreed at the same time as the unit price, since 650 x 369 x 452 mm and 31 kg per cabinet drive both case dimensions and shipping cost.
Finally, request the condition detail behind the Grade A label: photographs of each driver, the rigging points and the cabinet exterior, plus any available impedance or functional check on the HF section. If you are comparing this against other options first, browse the second hand line array speakers range and then send your array plan through the contact form so availability and quantity can be matched to your design.
