Fi X Review

I promised a review of the Fi X series for those of you who are thinking about ordering some of the remaining stock.

First here are a few pics:

Here is a little background. The X's were purchased to replace a blown sub in the old treo of Kicker Solo-baric 12"s. These were a temporary solution so the owner wouldn't be without sound between now and the purchase of his new vehicle.

Here are the box specs; 1.1cf after displacement, sealed with individual chambers for each sub. 14 ga speaker wire and wired to .67ohms. They are powered by a MMATS D300hc. Everything is controlled by an Eclipse CD7000.

My initial impression was, wow, these actually sound a lot better than the solos. They played deeper without question, they just weren't as loud. I talked to Shawn later that day and he said to allow the suspension to break in and report back. I let the owner have the truck back and told him to beat the hell out of them. One week went by and I got the phone call, I had to have a listen. After bringing the truck by I noticed a marked improvement. They were indeed louder and sounded a ton better than the others.

He just got here, we are going to go have a listen to a few different things he and I both like. Back in a few.

OK, filled our bellies and listened to a ton of music. First up was Diesel Boy-Project Human. We picked this due to its quick punchy drums and wide range of low tones. I will say that you won't win any spl contests with these, but man they sound good. Very very tight. Handled the quarter beats and d&b without issue. One thing he and I both noted was how linear these were. I would say every bit as linear as my Q's. I have them crossed at 80Hz and 12db/octave slope. We messed around with different settings and both thought this was ideal point. We played a ton of different techno cd's after this. From Tiesto to DJ Baby Ann and they handled them all in stride.

Next we played some rock. Chevelle, GodSmack, and some Pink Floyd. I feel like they had no issue keeping up with the drums in any of the tracks. So far they have shown no signs of fatigue.

Lastly we played Gorilla Zoe. Hood N*gga was pretty impressive. This was the first time the subs let us know we were pushing them too hard. In that song the drums are very heavy and well above the level the bass line was recorded at. I backed the non-fader level down one and they no longer sounded stressed.

I would rate this as a great daily sub. Very linear in output from 28-80Hz. I wouldn't give them more than 400 watts. That is about where we are and with a good recording at above normal listening levels they will tell you about it. I would say this is a great sub for the person who doesn't mind not being able to set off car alarm and enjoys a nice linear response. For the price, you really can't beat it if the sub meets your requirement.

Hope this helps. If I left anything out, just post and I will answer.

It is. The mark was from the solos. Not sure what the white powder looking stuff is. I didn't even notice it until I looked at the pic. He is a pretty big guy so he used to keep the seat back with the old subs. Most likely resulting in its death. Before I took the pics, I made sure he wasn't too far back, he listened.

No room to port b/c he wanted to keep the amps as they were. The entire system was installed by a B&M to his specifications. The only thing I did was swap and wire the subs and replace his old HU and run new RCA's. These are temporary. So no real need to redo the install. He is going to look at a Nissan Armada tomorrow. If he gets that, we will most likely be doing 4-Q 15"s, or if he lets us wall it, 4-BTL 18"s. I am pushing for him to wall it.
