The Prime R2SD2-12/R2SD4-12 from Rockford Fosgate is a 12-inch shallow subwoofer that impresses with its compact design requiring minimal space. Featuring a shallow motor design and a mica-injected polypropylene cone, it delivers precise bass notes. This subwoofer is ideal for sealed enclosures and offers powerful performance of up to 400 watts with its 4mm² compression terminals and anodized aluminum voice coil former. The model stands out with its StampCast basket design with integrated spider venting, which effectively supports motor cooling. Innovative and powerful, it provides a balanced and intense listening experience.

If you have no space for bass, our R2 12-inch shallow subwoofer can satisfy your need for music with deep frequencies. Thanks to an enhanced motor structure that reduces the speaker's depth, these drivers also fit into tight spaces. The mica-coated polypropylene cones ensure clean and precise bass. The stamped baskets feature spider venting, which is usually only found in conventional, deep-mounted models to keep the motor cool! These shallow subwoofers are optimized for sealed enclosures.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
