Powerbass S-650T
6.5-Inch Thin Mount Coaxial OEM Speakers
Get a full 6.5″ sound upgrade in a slim package with the S-650T 6.5″ thin-mount coaxial speakers, an easy OEM replacement supplied and expertly fitted by Safe and Sound, the vehicle audio and security specialists with over 30 years’ experience.
A full-size sound where depth is tight
Plenty of doors and panels can take a 6.5″ speaker across the face but not behind it, where window mechanisms and tight cavities get in the way. The S-650T solves that. It is a drop-in OEM replacement built on a thin, shallow-mount design, so you get the fuller sound of a 6.5″ speaker in spaces where a standard one simply will not fit.
Smooth highs and a full low end
The S-650T is a true 2-way coaxial. A 0.75″ pure silk dome tweeter with a neodymium magnet and SEL (Sound Expander Lens) ring gives smooth, refined high frequencies, while the 6.5″ DDC-coated 2-layer paper cone reaches down to 63 Hz for warm, full mid-bass. The result is a clear, balanced sound from the same head unit and wiring.
Power and build to match
With 45W RMS per speaker and 135W peak, the S-650T stays clean as you turn it up. An EFF (Efficient Flux Field) motor structure with a 10 oz magnet and a rigid tooled basket keeps the design efficient and solid, while a double-pressed treated foam surround stands up to daily use. The shallow 2.0″ mounting depth is the whole point of this model, and the speakers are supplied as a pair.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
