Helix Compose FlexMount 25 CFMK25 VOL.1 Tweeter Adapterring voor Volvo

Installing these adaptor rings on my Volvo’s existing tweeter pods was surprisingly straightforward—the two-part design made fitting both 20mm and 25mm drivers a perfect match. Got a much cleaner, more precise soundstage without any cutting or filing.

The dual-ring setup let me drop in both a 25mm and a 20mm tweeter without any extra cutting, which saved me a solid hour of fiddling. It sits flush in the Volvo dash and the alignment pins made it genuinely click into place—no wobble or rattling once the grille went back on.

The two-part design is a lifesaver—I swapped from the 1” ring to the 0.75” one in under a minute, and the fit in my Volvo's dash is snug with zero rattling. These adaptor rings feel solid and machined, not like cheap plastic, which is exactly what you want when mounting tweeters.
