    • Tropo 8" dual 4
Size: 8 Inch - Dual 4 Ohm
I received two Tropo 8" subwoofers fast and clean. They are worth the price. They have a high fs at 50 hrz which im not real fond of. I have built two different slot ported boxes for them so far. The first is 1.5 cubic feet net with a 40 hrz tuning. The 2nd is 1.5 cubic feet with a 30 hrz tuning. At 40 hrz anything below 40 dropped off quickly. Bass at 30 hrz was non existent. At 30 the bass at 30 hrz was still pretty quiet. Bass box pro shows a huge spike no matter how I modeled these subs and couldn't even get close to a flat response. These sub do offer a real good punch above 40 hrz. The only negative is that who ever assembled the subs were inconsistent. The dust cap and the push termenals were off in alignment. To mount the subs with the logo flat the screw holes were not uniform so that just looks bad. All in all they are at least worth the price asked. Update: I finally ended up with 2 cubs tuned to 28 hrtz and satisfied. Descent bass around 28 to 50 and solid power handling. Still 4 stars for the dust caps not being straight with the mounting holes. The subs just look too good for this minor cosmetic mistake. ... show more

    • Outer seal is messed up
Size: 8 Inch - Dual 4 Ohm
Review Image by Mike Mike
Outer seal around outside of sub is not round at all and looks terrible- top left side- came out of the shipping bix that way. Sounds ok, but not expecting a brand new sub to look so bad in a new build. Disappointing. Contacted company and they told me that I did it and need to fix it myself- not right. ... show more
