Eminence references sensitivity to 1 W at 1 m at the nominal impedance, i.e. 2.83 V into 8 Ω, averaged over the usable frequency range; measured in a 2 × 2 ft baffle. Recommended enclosure volume according to the manufacturer: vented 12.7–37.9 L, sealed not intended (“N/A”).
Aluminium voice coil on a polyimide former, vented pole piece, pressed steel basket, paper cone with cloth surround. There was also the Delta 10B with 16 Ω, which Eminence still lists today. There is currently no product page for the Delta-10A on eminence.com.
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 130 – by the rule of thumb, this points to a vented enclosure and also makes the driver interesting for horns. This is based on an EBP of 189.

- 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) | 0.33 | 0.332 | consistent |
| EBP from Fs and Qes | EBP = Fs / Qes | 189 | 188.571 | consistent |
| Vd from Sd and Xmax | Vd = Sd · Xmax | 0.121 | 0.121 | consistent |
Power handling

- Programme power700 W
According to the footnote, several samples exceeded the rating according to EIA-426A, freely suspended and without temperature control. How Eminence determines programme power is not stated in the sheet.
Sources disagree: Xmax
- 3,5 mm – PDF p. 1, Thiele & Small Parameters Adopted
- 1,6 mm – PDF p. 1 (“Voice Coil Overhang (Xmax) 1.6mm”)
The 2004 sheet states 1.6 mm Xmax and, consistent with this, Vd 55 cm³; the 2014 sheet for the Delta-10A states 3.5 mm and Vd 121 cm³; all other Thiele-Small parameters are the same. Eminence presumably defined Xmax differently; the sheet says nothing about this. The newer sheet is used.
Sources disagree
- 233,2 mm – PDF p. 1, Mounting Information Adopted
- 229,7 mm – PDF p. 1, Mounting Information
The newer sheet gives a larger baffle cut-out. The newer value is used; with an older sample, measure before cutting.
Sources disagree
- 63–3700 Hz – PDF p. 1, Specification Adopted
- 65–3500 Hz – PDF p. 1 (“Usable Frequency Range 65Hz - 3.5kHz”)
Both figures come from Eminence; the newer sheet is used.
Sources disagree
- ventiliert 12,7–37,9 L – PDF p. 1, Mounting Information Adopted
- ventiliert 14–24 L – PDF p. 1, Mounting Information
Both figures come from Eminence; the newer sheet is used.
