- Plus One™ Woofer Cones
- Harman's gepatenteerde (VS patent #7,548,631 ) Plus One™ polypropyleen cones zorgen voor groter luidspreker-conus oppervlakte dan andere cones in zijn klasse. Het resultaat is een hogere gevoeligheid, verhoogde laagfrequentie-uitgang en meer muzikaal karakter.
- Frequency Response Up to 21kHz
- Hear what you’ve been missing — the JBL GT7 Series offers a frequency response that delivers the full-range response associated with exceptional sound.
- Individually Voiced
- For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That’s not the case with JBL. We don’t only listen to our speakers against the competition — we voice them against each other to ensure each line has the consistent JBL sound signature that’s known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.
- Affordable Pricing
- The JBL GT7 Series are all designed to give audio enthusiasts more boom for the buck — while they maintain a conservative price point, there is never a compromise in sound.
- OEM-Level Reliability Testing
- JBL tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.
- Mounting Hardware
- Grilles, mounting adapter rings and/or tweeter cups are all included in each model (where necessary). This allows for greater flexibility and more personalization when installing.
Plus One® Technology
Plus One carbon-injected cones provide more overall speaker-cone area than other cones in its class.

Rated 4 out of 5 by Seicento from Aus 10cm kann auch jbl keine Wunder hevorbringen In einen Seicento eingebaut. Passt problemlos. Klingt deutlich besser als Serie oder crunch-Zeugs aber natürlich bleibt es 10cm im Seicento. Bei mittleren Lautstärken ganz angenehm. Läuft mit einem Kennwood BT-45U
