[Please check before ordering]
This item is made to order. Please contact us before ordering for an individual lead-time estimate. The system stock label (such as "low stock") does not indicate finished goods in stock.
The displayed approximate product weight of 2 kg is a shipping-rate calculation setting, not the measured product weight.

Upper mounting holes: 4 holes, PCD 155.1 mm (design value)
Mounting opening diameter: 146.0 mm (design value)
Upper ring outside diameter: 170.0 mm (design value)

[Exact PCD-value candidates]
No exact 155.1 mm PCD match was found in the checked shop speaker-dimension ledger. The four upper holes secure an intermediate ring such as PCD1; they do not establish direct speaker compatibility.

[Shop-confirmed speaker combinations]
No publishable installation-confirmation record for a specific speaker with this baffle is currently registered. Matching dimensions alone do not establish fitment.

[Required-cutout 146 mm candidates: installation unverified]

• ETON CSR-16 (midwoofer in set) (item 1753/7966; required cutout 146 mm; outer diameter 165 mm; installation depth 60 mm)
• ETON ONYX-16 (item 1750; required cutout 146 mm; outer diameter 165 mm; installation depth 79.5 mm)
• ETON CORE-S2 (midwoofer in set) (item 1743; required cutout 146 mm; outer diameter 165 mm; installation depth 79.5 mm)
• ETON CORE-S3 (midwoofer in set) (item 1742; required cutout 146 mm; outer diameter 165 mm; installation depth 79.5 mm)
• ZR Speaker Lab ZR Extravagance N°1 -brushed- (item 2773; required cutout 146 mm; outer diameter 166 mm; installation depth 65 mm)

These are opening-dimension candidates for the baffle alone. Fastener PCD, hole count and pattern, mounting method, terminals, basket geometry and vehicle clearance remain unverified. Equal nominal opening sizes require tolerance checks. The PCD1 ring has an approximately 145.3 mm opening (scan-derived value), so this list does not establish compatibility through PCD1. Please consult us about the vehicle and speaker combination before ordering.
