SA15 v.2 by Sundown Audio

The Sundown Audio SA Series, which includes the Sundown Audio SA15 v.2, is the top-selling series from Sundown Audio! The new v.2 version features a larger, more powerful motor to drive the bigger 2.75-inch coil and stronger centering—this maintains the perfect balance of the original SA Series while increasing the power handling to 1000 watts RMS.

The Sundown Audio SA15 v.2 has a linear excursion (XMAX) of 19 mm, which allows for just over 35 mm x-mech. The motor also features a large magnet ID shorting ring (Faraday ring) to reduce distortion caused by inductance and inductance variation over the stroke.

The 18-inch model features a larger motor than the SA-10/12/15 v2, with a diameter of 205 mm and a magnet gap height of 60 mm. It has a large centering spider pack with a 234 mm diameter for very high mechanical excursion capacity. It uses the same 2.75″ coil as the other subwoofers in the SA v.2 series for a rated power of 1000 watts RMS.

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!
