- Coaxial driver
- Nominal size
- 15″
- Nominal impedance
- 8 Ω Manufacturer
- Minimum impedance
- 6 Ω Manufacturer
- Sensitivity
- 99 dB Manufacturer
- Frequency range
- 45 Hz – 4,000 Hz Manufacturer
- Voice coil Ø
- 75 mm Manufacturer
- Winding height
- not available
- Gap depth
- not available
- Flux density
- not available
- Magnet
- neodymium (shared magnet for LF and HF)
- Weight
- 5.9 kg Manufacturer
- Baffle cut-out Ø
- 354 mm Lavoce gives no cutout diameter. The value is the basket diameter directly behind the flange according to the dimensional drawing, i.e. the minimum size of the cutout; one to two millimetres of clearance make installation easier. Manufacturer
- Overall diameter
- 393 mm Manufacturer
- Mounting depth
- 196 mm Overall depth including flange; 181.1 mm from the rear of the flange. Manufacturer
- Displacement
- 5 L Manufacturer
- Recommended enclosure volume
- not available
The product page gives no measurement condition for sensitivity. The crossover has to compensate for the 8 dB difference between the LF and HF sections.
What can this driver do?
Link to section “What can this driver do?”Simulation from the datasheet values above. The suggestions are calculated, not stated by the manufacturer.
The EBP is above 100 – by the rule of thumb, this points to a vented enclosure (bass reflex). This is based on an EBP of 112.2.
- Net volume
- 175 L
- Tuning frequency
- 46 Hz
- F3 (−3 dB)
- 42.7 Hz
- F6 (−6 dB)
- 38.7 Hz
- F10 (−10 dB)
- 34.5 Hz
- Sensitivity (2.83 V / 1 m)
- 99.2 dB
- Max. SPL at 42.7 Hz
- 121.2 dB
- Max. SPL at 85.5 Hz
- 123 dB
- Xmax limits below
- 101 Hz
- Ports
- 1 × 250 mm
- Port area for 17 m/s
- 478 cm²
- Max. port velocity
- 16.6 m/s
- Port length
- 21.3 cm
- at 400 W
- Maximum SPL (limited by Xmax)
- Power into 8 Ω (nominal impedance of the wiring).
- Flattest alignment: lowest F3 without the response rising more than 0.25 dB above the passband level or dropping more than 0.5 dB at 2 × F3.
- The 17 m/s limit (about 5 % of the speed of sound) is a common rule of thumb against port noise, not a standard. Rounded port ends allow higher values.
- Lumped-element Thiele/Small model, Half space, 1 m, chamber losses QL 7, Le as a plain inductance, no room influence. At high levels (heating, non-linear Bl and Cms) real results are lower.
Thiele-Small parameters
Link to section “Thiele-Small parameters”Small-signal parameters as stated by the manufacturer. They change with temperature and level.
Plausibility check
Link to section “Plausibility check”We recalculate dependent values from the datasheet. We flag deviations above 3 %.
| Check | Formula | Datasheet | Calculated | Result |
|---|---|---|---|---|
| Qts from Qes and Qms | Qts = Qes · Qms / (Qes + Qms) | 0.39 | 0.385 | consistent |

High-frequency section
Link to section “High-frequency section”A coaxial driver combines two transducers in one basket. The values here apply only to the high-frequency section – its sensitivity and power handling must not be combined with those of the low-frequency section.
- Throat diameter
- 36 mm
- Nominal impedance
- 8 Ω
- Minimum impedance
- 7.8 Ω
- Sensitivity
- 107 dB
- Frequency range

- Voice coil Ø
- 75 mm
- Diaphragm
- titanium
- AES (HF)80 W
- Programme power (HF)160 W
The HF throat is 36 mm (1.4″). Crossover at 1200 Hz according to the manufacturer.
