Review: i replaced my yamaha sub ycs 1212 with this rockford in a sealed box same as specified by rockford...the yamaha was tired but twice the rockford for low bass pedals that we find on live recordings from rush or genesis or floyd or marillion....the fostgate seems to be cut at 50 hz and wont go down to 30 hz like my yamaha does. it just gives a huge 50 to 80 hz peak. my amp is a clarion as 1100 sub amp with crossover and variable boost 12 db 30hz. i know it is areally good amp for sub harmonic cause ive compared it with 3 other amps when i bought it on my yam 1212. so if your a disco buff the fosgate is for you but if you want these bass pedals out there...this fogate doesn't know what it is! follow up...i've build the recomended duct tube box with 1 inch particle board...same problem but less `punchy`..this is a good woofer but not subwoofwr...it doesnt'go below 40 hz...probably bult that way by fostgate so it doesn,t blow! the good thing is that i repaired my Yamaha ycs 1212 and put it in that box...well it`s now back down to 30Hz with my Marillion spirit of eden , which is a superb test for subharmonic lows, Genesis `the way we walk`long ones...Tool Undertown no4 (accolades) many Rush live bass pedals etc
Review: I have two of these set up in a closed box with a 300 watt amp. The subs dont hit super hard, however I feel that the bass is perfectly boosted now with my system in my truck. On songs with no bass, its not over powering. Songs that have heavy bass, the subs come to life and improve the music greatly. Some people think that they are too weak and are a waste of money, that is until you tell them how much it cost. With the amp, box, and two subs, you can have a great starting set up for under 200$. I think they are worth the money for that if you listen to other music than just stuff that is very bass heavy.

*by A***F on 31 August 2014*

Der Subwoofer spielt den Bass druckvoll und zufriedenstellend... bis man die Lautstärke erhöht... Schon bei relativ geringer Lautstärke ist mir das Anschlagen der Spule aufgefallen (lautes Klacken), was nicht zu überhören ist. (Es liegt nicht am Verstärker) Er sieht zwar schick aus, aber tiefe Frequenzen (unter 35hz) sind gar nicht mehr zu hören und am Außenring des Subwoofers, wo sich die Schraublöcher befinden, ist an der Rückseite kein Stoff angebracht, der Schwingungen zwischen Metall und z.B. Holz des Gehäuses abdämpft. Wer keine tiefen Bässe hören möchte, für den ist der Subwoofer zu empfehlen.
