SPL57.1 5x7 6x8" 14x19cm 4Ohm Coaxial 2 Way Speaker Pair 250w RMS

World RRP: £28.99

Category: Coaxial & Component Speakers

Product code: SPL57.1

Now shipping Version 2 of this product - Designed to be installed into any of the many popular 5×7 or 6×8 inch OEM locations with minimal hassle, the SPL57.1 is from exactly the same bloodline as our other upgrade class speakers. Featuring stiff and lightweight woven composite cones, silk dome neodymium tweeters and large motor structure for higher power handling and good frequency response. The 5×7/6×8 size is actually quite generous for the production of midbass, and when properly installed these speakers can compete with much more expensive equipment (and all this from behind your standard trim grille!) They have stealth written all over them.
