Featuring a \u003cstrong\u003enon-pressed paper cone\u003c\/strong\u003e, \u003cstrong\u003ecloth surround\u003c\/strong\u003e, a \u003cstrong\u003eferrite + neodymium hybrid magnet system\u003c\/strong\u003e, a \u003cstrong\u003e1.5\" \/ 38.6mm CCAW voice coil\u003c\/strong\u003e on a \u003cstrong\u003eglass fiber former\u003c\/strong\u003e, and an \u003cstrong\u003ealuminum basket\u003c\/strong\u003e, the PA6B-4 delivers \u003cstrong\u003e300W RMS \/ 600W max\u003c\/strong\u003e at \u003cstrong\u003e97 dB sensitivity\u003c\/strong\u003e with a frequency response of \u003cstrong\u003e100 Hz–10 kHz\u003c\/strong\u003e. Sold as a single speaker — order the quantity you need for your build.\u003c\/p\u003e\n\n\u003cp\u003eThe PA6B-4’s \u003cstrong\u003eferrite + neodymium hybrid motor\u003c\/strong\u003e (30 + 3 oz) combines the high-flux density of neodymium with the thermal mass of ferrite — delivering exceptional sensitivity and sustained high-power performance without thermal compression. The \u003cstrong\u003e7.2mm one-way Xmax\u003c\/strong\u003e gives this driver serious linear excursion capability for a 6.5\" midrange, allowing it to move real air at high output levels without distortion. With a \u003cstrong\u003eQts of 0.556\u003c\/strong\u003e and \u003cstrong\u003eFs of 150 Hz\u003c\/strong\u003e, the PA6B-4 is optimized for use with a high-pass crossover at \u003cstrong\u003e160 Hz\u003c\/strong\u003e — keeping it in its optimal operating range and protecting it from low-frequency content that would reduce output and increase distortion.\u003c\/p\u003e\n\n\u003cp\u003eThe non-pressed paper cone delivers a natural, detailed midrange character with low mass for fast transient response — ideal for vocal presence, instrument clarity, and upper-midrange detail in a high-output system. Whether you’re building a competition SPL or SQL system, upgrading a bagger for maximum output, or building a high-efficiency 3-way active front stage, the PA6B-4 is the 6.5\" midrange that delivers.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose the SoundQubed PA6B-4?\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e300W RMS \/ 600W MAX @ 4Ω\u003c\/strong\u003e — Pro-grade power handling in a 6.5\" midrange — built for high-output competition and demo builds.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e97 dB Sensitivity (1W\/1m)\u003c\/strong\u003e — Exceptionally high efficiency — delivers massive output with relatively modest amplification.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFerrite + Neodymium Hybrid Motor (30 + 3 oz)\u003c\/strong\u003e — Best of both worlds — neodymium flux density for sensitivity, ferrite thermal mass for sustained high-power performance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7.2mm One-Way Xmax\u003c\/strong\u003e — Serious linear excursion for a 6.5\" midrange — moves real air at high output without distortion or mechanical failure.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1.5\" CCAW Voice Coil on Glass Fiber Former\u003c\/strong\u003e — Lightweight, thermally efficient winding on a rigid former — handles sustained high-power use without thermal compression.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNon-Pressed Paper Cone\u003c\/strong\u003e — Low-mass, natural-sounding cone material for fast transient response and detailed midrange reproduction.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAluminum Basket\u003c\/strong\u003e — Rigid, resonance-free basket construction — pro audio grade in a car audio package.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold Single\u003c\/strong\u003e — Buy exactly what you need — order quantity two for a stereo pair.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eInstallation \u0026amp; Pairing Recommendations\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eCrossover Configuration:\u003c\/strong\u003e The PA6B-4 is a dedicated midrange driver — always use a high-pass crossover set at \u003cstrong\u003e160 Hz minimum\u003c\/strong\u003e to protect the driver and keep it operating in its optimal range. For competition and high-output builds, use an active crossover or DSP to set precise HPF and LPF crossover points. A band-pass configuration (160 Hz HPF \/ 8–10 kHz LPF) is recommended for maximum output and driver protection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAmplifier Pairing:\u003c\/strong\u003e The PA6B-4 handles \u003cstrong\u003e300W RMS at 4Ω\u003c\/strong\u003e. Use a dedicated amplifier channel with at least 150–300W RMS at 4Ω for best results. The SoundQubed Q4-2000 (325W x4) or Q4-3200 (520W x4) are excellent matches for a multi-driver pro audio front stage build.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3-Way Active Front Stage:\u003c\/strong\u003e The PA6B-4 pairs naturally with the \u003cstrong\u003eSoundQubed HDX Series 2.2\" Titanium Dome Tweeter\u003c\/strong\u003e (crossed at 3.8 kHz HPF) and a dedicated subwoofer or midbass driver for a complete 3-way active front stage.

dedicated midrange?\u003c\/strong\u003e\u003cbr\u003e\nA: It’s a \u003cstrong\u003ededicated pro audio midrange driver\u003c\/strong\u003e — not a full-range speaker. It’s designed to be crossed over at 160 Hz HPF minimum and used with a dedicated tweeter and subwoofer or midbass driver. Always use a high-pass crossover to protect the driver and maximize output.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What’s the difference between the PA6B-4 and the PA69B-4?\u003c\/strong\u003e\u003cbr\u003e\nA: The PA6B-4 is a \u003cstrong\u003e6.5\" round midrange\u003c\/strong\u003e (300W RMS, 97 dB, Fs 150 Hz, HPF at 160 Hz) while the PA69B-4 is a \u003cstrong\u003e6x9\" midrange\u003c\/strong\u003e (350W RMS, 99 dB, Fs 100 Hz, HPF at 100 Hz). The PA69B-4 has a lower Fs and handles more power, making it better suited for locations where a 6x9\" footprint is available. The PA6B-4 fits standard 6.5\" round locations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What amplifier should I pair with the PA6B-4?\u003c\/strong\u003e\u003cbr\u003e\nA: The PA6B-4 handles 300W RMS at 4Ω. The SoundQubed Q4-2000 (325W x4) or Q4-3200 (520W x4) are excellent matches. Use a dedicated amplifier channel per driver with an active crossover or DSP for precise crossover point management.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Is this sold as a pair or single?\u003c\/strong\u003e\u003cbr\u003e\nA: The PA6B-4 is sold as a \u003cstrong\u003esingle speaker\u003c\/strong\u003e.
