SPL4.1 4" 10cm 4Ohm Coaxial 2 Way Speaker Pair 200w RMS

World RRP: £37.99

Category: Coaxial & Component Speakers

Product code: SPL4.1

Now shipping Version 2 of this product - The SPL4.1 is a bit of a legend. It should not be possible to produce so much power from a driver as small as this! The magic happens because of the super high density ceramic magnet and ultra efficient motor structure. You will need to help the job along with a sensible crossover frequency and quality installation but given this the SPL4.1 will literally sing. Partnered with a small woofer such as the SPL8.1 or even the SPL10.1 it is now truly possible to produce full range sound from a tiny system with minimal footprint. Great news for those with minimal space.
