What this driver's data tells us
PRV Audio MT8SW800 D4 Subwoofer
PRV Audio MT8SW800 D4 Subwoofer is a Woofer. Its available data describe the following design trade-offs.
The database lacks Fs, Qts, Vas. A dependable enclosure-size and bass-extension assessment needs those values; none have been guessed.
No confirmed sensitivity reference is available, so relative loudness for the same input cannot be assessed here.
Basis and further reading
Calculated from published parameters; this is not a listening review. Box sizes are net acoustic volume for one driver. Room gain, EQ, damping material and construction losses are excluded.
Voltage-to-power conversion uses nominal impedance. These size, cutoff and sensitivity bands are editorial guides, not audio-quality standards.

Resonance · FsNot recordedDisplay range: 10–2,000 Hz · log
The driver's free-air resonance. A lower value can help a bass design, but the enclosure, excursion and response determine usable bass. It is not the finished speaker's bass cutoff.
SensitivityNot recordedDisplay range: 65–115 dB
Output at the manufacturer's stated input and distance. 1 W and 2.83 V are different references for many impedances. This card keeps the original value and reference; it is not an efficiency or sound-quality rating.
Resonance damping · QtsNot recordedDisplay range: 0–1.5
Electrical and mechanical damping combined. Lower values indicate stronger damping at resonance. It helps choose an enclosure alignment, but does not tell you whether the sound is fast, warm or detailed.
Suspension compliance · VasNot recordedDisplay range: 0.1–1,000 L · log
The volume of air with the same compliance as the suspension. It is not a recommended box volume. Use it together with Fs and Qts.
Linear excursion · XmaxNot recordedDisplay range: 0–30 mm
Published linear excursion. Definitions differ between manufacturers; verify one-way versus peak-to-peak values. It does not by itself predict distortion or maximum safe output.
Radiating area · SdNot recordedDisplay range: 1–1,500 cm² · log
Effective radiating area, not the frame's outside diameter. It helps estimate how much air a cone moves when combined with excursion.
Sensitivity reference: Not recorded
Which enclosure could work?
Screening guidance from the available parameters, not a guarantee. A manufacturer's exact-model enclosure plan takes priority. Listening quality cannot be ranked from T/S parameters.

Bass mini-lab
Move the volume slider. Both curves use the same box volume; the bass-reflex tuning is adjustable.
The mini-lab needs valid Fs, Qts and Vas for a bass driver. It stays unavailable when those inputs are missing or the driver has another role.
Frequency response Response
Common scale for all drivers: 20–20,000 HzNo usable response data is recorded
Unavailable response data is not guessed or plotted.
What do published reviews say?
Attributed summaries, not our listening test or a consensus score. The enclosure, crossover, room and listening level affect each review. Exact model and impedance are checked.
No exact-model listening review has been verified for this page yet. We do not infer tonal quality from T/S parameters or borrow reviews of similar model names.
