Engineered by Simulation
Audison's R&D team modelled the driver using finite element (FEM) software, then refined it through intensive prototyping to reach the ideal transducer.

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: 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.
Q: Is the TH 6.5 II SAX a full-range speaker?
A: No. It is a dedicated midbass woofer with a 40Hz to 4.5kHz response, intended to be used with a crossover alongside a midrange and/or tweeter, such as the Thesis TH 3.0 II voce and TH 1.5 II violino.
Q: How much power can the TH 6.5 II SAX handle?
A: It is rated at 150W continuous and 300W peak, with a 4 ohm impedance.
