Score: 4 / 5 Excellent
The JBL Studio 690 is a high-performance 2.5-way floorstanding loudspeaker engineered for dynamic home theater and two-channel Hi-Fi systems. Positioned as the second-largest model in JBL's Studio 6 series, the Studio 690 combines live-concert acoustic dynamics with clean, room-friendly aesthetics.
At the top of the driver array is JBL's 2414H-1 1-inch high-frequency compression driver mated to a proprietary High-Definition Imaging (HDI) horn waveguide, delivering precise stereo imaging, wide soundstage dispersion, and high clarity. Low-frequency duties are handled by dual 8-inch PolyPlas cone woofers operating in a 2.5-way crossover network and backed by a rear-firing tuned bass-reflex port, delivering controlled bass extension down to 36 Hz with low distortion.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- High-Definition Imaging (HDI) Waveguide: Horn-loaded 1-inch compression driver optimizes high-frequency dispersion and detail for live-concert acoustic accuracy.
- Dual 8-Inch PolyPlas Woofers: Low-mass, high-rigidity polymer-coated paper cones minimize driver breakup and distortion during heavy dynamic peaks.
- 2.5-Way Crossover Architecture: Dual crossover network (600 Hz and 1.7 kHz) allows both woofers to deliver low bass, while dedicated upper-midrange frequencies pass cleanly to the horn.
- Rear-Ported Bass-Reflex Enclosure: Tuned rear port minimizes turbulence and enhances low-end impact.
- Gold-Plated Binding Posts: Heavy-duty, bi-amp / bi-wire capable gold-plated binding terminals ensure optimal signal conductivity.
- Vibration Isolation Base: Sturdy cabinet construction supported by included carpet spikes and rubber feet for mechanical stability.

Our Grading Guarantee
All equipment listed on this site undergoes a multi-point inspection by our staff. While we use a standardised 1–5 Grading Scale, please note that "pre-owned" implies some degree of previous life. We strive for transparency and use the following terms:
- Visual Inspection: Condition grades are subjective but applied conservatively. We provide high-resolution photography of the actual unit for sale (no stock photos). We encourage buyers to zoom in on all images as they constitute part of the formal product description.
- Functional Testing: Unless labelled Grade 1 , all units have been tested for power, input/output integrity, and basic mechanical operation. Vintage units (20+ years) are tested for "period-appropriate" functionality; unless specified, internal components like capacitors are original.
- "Fair" Exclusions: Items graded 1 (Fair) are sold strictly for parts or repair. These items are ineligible for returns, refunds, or "Item Not as Described" claims regarding their condition.
- Return Window: If a unit arrives in a condition significantly different than its assigned grade (e.g., a Grade 4 unit arrives with a shattered faceplate), you must notify us within 24 hours of delivery.
