• PRV Audio 6MB200-4 — Full Description
• The 6MB200-4 is a high-sensitivity mid-bass driver with a 6-inch nominal cone diameter, 4-ohm impedance, and a 1.5-inch copper voice coil. It is intended to reproduce the punchy portion of the audio spectrum between deep bass and the lower/middle vocal range.
• Its relatively high sensitivity makes it capable of producing substantial acoustic output without requiring enormous amplifier power. PRV specifically describes it as suitable for small enclosures, bookshelf/satellite speakers, surround speakers, studio monitors, three-way cabinets, and car-audio installations.

• What the numbers mean
• 🔊 100 W RMS / 200 W program
• The driver is rated for 100 watts continuous/AES power and 200 watts program power. This means you shouldn't interpret "200 W" as its continuous thermal rating. For a long-term installation, designing around roughly 100 W RMS per driver is the safer interpretation.
• ⚡ 4-ohm impedance
• The 4 Ω nominal impedance makes it appropriate for many car-audio and pro-audio amplifiers.
• For example, two of these drivers wired:
• Parallel: 2 Ω total
• Series: 8 Ω total
• The actual impedance varies with frequency because a loudspeaker isn't a fixed 4-ohm resistor.
• 📢 93 dB sensitivity
• The original model is rated around 93 dB sensitivity, which is quite efficient for a small mid-bass driver. That means it can produce good output with comparatively modest amplifier power.
• The v2 is slightly more sensitive at 93.5 dB.
• P
• PRV Audio
• 🎵 Frequency range: 125–4,500 Hz
• This is not a subwoofer. It is designed primarily for mid-bass and lower-midrange.
• A typical system might divide the spectrum approximately like:
• Subwoofer → 20–125 Hz
• 6MB200-4 → ~125–4,500 Hz
• Tweeter/compression driver → above ~4,000–5,000 Hz
• PRV recommends a 125 Hz high-pass filter with a 12 dB/octave slope when trying to obtain its full rated power handling.
• P
• PRV Audio
• That high-pass filter is important because the driver's free-air resonance is around 114.5 Hz. Trying to make a 6-inch mid-bass driver reproduce very deep bass at high power can cause excessive cone excursion.
• Motor and voice coil
• The driver uses a 1.5-inch (38 mm) copper voice coil mounted on a Kapton former. The original version has a 12.5 mm voice-coil winding depth and a 5.5 mm magnetic gap.
• P
• PRV Audio
• The magnetic motor uses a ferrite magnet, while the basket/frame is made from stamped steel. This gives the driver a relatively rugged construction while keeping its weight around 3.3 lb.
• Thiele-Small parameters
• The T/S parameters are particularly useful if you're designing an enclosure.
• For the original 6MB200-4:
• Fs: 114.5 Hz
• Qms: 24.30
• Qes: 0.86
• Qts: 0.83
• Vas: 5.15 L
• Sd: 154 cm²
• Mms: 12.41 g
• Cms: 0.155 mm/N
• Bl: 6.18 Tm
• Xmax: 4.87 mm
• P
• PRV Audio
• The relatively high Qts of 0.83 and relatively small Vas of 5.15 L make this a very different driver from a conventional deep-bass woofer. It is much more naturally suited to mid-bass duty in a relatively compact enclosure than to trying to produce subwoofer-level bass.
• Physical dimensions
• For installation, pay particular attention to the cutout and mounting depth.
• Outside diameter: 166 mm / 6.53"
• Baffle cutout: 143 mm / 5.63"
• Mounting depth: 66 mm / 2.60"
• Overall depth: 74 mm / 2.91"
• So you need a baffle capable of accepting approximately a 5.63-inch cutout, while allowing at least 2.6 inches of mounting depth, plus some additional clearance for the terminals and wiring.

• 6MB200-4 vs. 6MB200-4 v2
• This is important because there are two versions.
• The original 6MB200-4 is rated at:
• 100 W RMS
• 200 W program
• 93 dB
• 125–4,500 Hz
• Fs 114.5 Hz
• Qts 0.83
• The 6MB200-4 v2 is an updated design with:
• 100 W nominal power
• 200 W continuous program
• 400 W peak
• 93.5 dB sensitivity
• 125–6,500 Hz
• Fs 123.79 Hz
• Qts 0.97
• Xmax 4.80 mm
• Vas 3.97 L
• The physical dimensions are essentially the same.

• PRV's current product page identifies the 6MB200-4 v2 as a 6.5-inch-class midbass product, although its actual nominal driver diameter is 6 inches (152 mm).
• P
• PRV Audio
• Best applications
• I'd consider the 6MB200-4 particularly well suited to:
• 🚗 Car audio mid-bass
• 🔊 3-way speaker systems
• 🎚️ Professional/PA speaker systems
• 🏠 Compact Hi-Fi speakers
• 🎛️ Studio monitor projects
• 📦 Small speaker enclosures
• 🔧 Replacement midrange/mid-bass driver applications
• It is especially useful when you want punch and efficiency rather than very deep bass.
• Bottom line
• The PRV Audio 6MB200-4 is essentially a high-efficiency 6-inch mid-bass driver built to deliver strong, clean output from roughly the upper-bass region into the lower/midrange. Its 4-ohm impedance, 93 dB sensitivity, 100 W RMS rating, 1.5-inch voice coil, and compact 6.53-inch overall diameter make it a versatile driver for car audio and compact multi-way speaker designs.
