Description
The Jensen P8R is an 8-inch, 25-watt, 8-ohm replacement speaker built for players and techs restoring vintage-style combos or small extension cabinets. Its voicing leans bright and clean at low volume, then opens into a warm, fuzzy overdrive character as you push the gain — a classic recipe for guitarists chasing shimmering highs with smooth, forgiving distortion. Bassists using it in smaller rigs will hear a similarly warm-and-bright signature.
- Lows: loose
- Mids: subdued

- Overdrive: smooth
Build specs (8Ω): nominal diameter 207 mm (8 in.), voice coil diameter 25 mm (1.00 in.), magnet weight 200 g (7.00 oz), overall weight 2.65 lbs, flux density 0.96 T.
Thiele-Small parameters include voice coil DC resistance (RE) of 6.70 Ω, resonance frequency (ƒS) of 130.0 Hz, mechanical Q factor (QMS) of 9.18, electrical Q factor (QES) of 2.30, total Q factor (QTS) of 1.84, and mechanical moving mass (MMS) of 9.3 g.
For techs speccing replacement drivers or building small-format cabs where tonal character matters as much as raw output, the P8R offers a well-documented, vintage-flavored option with predictable behavior across its rated power and impedance.
