LCS-12 V2 by Sundown Audio

The subwoofers of the Sundown Audio LCS series, including the Sundown Audio LCS-12 V2 12-inch shallow subwoofer, are known for their impressive bass performance and high reliability. Typical entry-level subwoofers are heavily limited in terms of linear excursion, mechanical robustness, and thermal performance—these are all aspects that Sundown Audio has taken to the next level in the Sundown LCS series. The refreshed v.2 update features a completely new, custom-made frame, push terminals, a rubber mounting gasket, and improved tinsel leads.

A double-stacked magnet structure and an extremely long voice coil allow for a class-leading linear x-max of 14 mm in one direction, in addition to high mechanical clearance (over 2" peak-to-peak). The large coil, combined with gap venting, the beveled pole piece design, and optimized pole venting, gives the LCS series impressive thermal performance. Mechanical stability and durability are ensured by the strong paper cone, robust foam surround, and a high-quality spider with fully stitched tinsel leads. All key areas of subwoofer longevity have been addressed to the maximum possible level in this category.

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!
