If the voice coil didn't match up according to year would the sub still work. '09 recone on a '08 motor. Please tell me yes!

Bumper! Looking for more input

Bought my sub second hand and need a recone. How do I tell the difference between '08 & '09 BL models. I have a 15".

One con that I just thought of is cubic feet. Maybe not enough for 2 15's?

Ok what's the deal with separate chambers for running more than one sub? How crucial is it really? I really want to end up with 2 15's in my Toyota Yaris sedan. Biggest box I can get in there is 32w x 16h x 26d (outside dim.). If the subs are exactly the same and amps are gain matched it shouldn't be that bad right? I know it's not ideal, but I really want the 2 15's.

Ok, I get it. I would be losing output. Basically becoming less efficient. At least I wouldn't be damaging the sub. Thanks for the help.

I'm looking into buying a 15" BTL fully loaded. My question is, can I tune my box lower than the recommended fs frequency? If I did, would it affect the sub in a bad way? Poor sound quality? Just wondering if there would be a negative effect on the sub. I think the fs frequency on the 15" BTL is 37.9. I like low frequency hip hop and want to tune my box low like 30 hz (at the lowest 25 hz). Is this not a good idea, what would be the result?

most likely the enclosure is just fine, it's tuned to the Fi recommended specs..... you should set your gains and subsonic with 0db reference test tones and a DMM to get the settings much closer.... and don't use the BASS BOOST on the head unit or the amp.... those are settings befit for failure..... what was your sub wired to? 4, 2, or 1 ohms?? The sub was dual 2 wired to 4 ohm. I think it was also a loose nut behind the knobs!

Had the gain set to a little more than half, subsonic filter between 25 & 30 hz, bass boost on head unit was at 1 out of 5, bass knob was like half way up (maybe a little more). So from what you are saying, more than likely my settings are way off. Maybe I should also tune lower? An upgrade to a bigger amp for louder bass? Maybe even think of a sealed enclosure for daily. would a box tuning of 25hz sound decent?

The sub is in a 3.0-3.1 cubic foot enclosure tuned to around 32-33 hz. Im running it of a JL 1000/1. I was playing songs like "soul survivor" Akon and Jeezy.

hey whats up, I am learning about enclosure design and tuning and was wondering about two terms "imp rise" and "unloading". I breezed through a thread on imp rise and got some very good information. Its the unloading part that im not to clear on. I have a 15" Fi BL Loaded and think that I have damaged it due to unloading (I think). My question is how does it affect the subwoofer, what kind of damage can this do, can a recone kit fix the sub if broken due to unloading. I was having problems where my sub would cut out then cut back in for some reason as I was playing low frequencies. The amp was not clipping or going into protect as I could see all the LED's while this was happening. So again the sub would kind of fade out at low frequencies then after a while start hitting again. I was beating on it yesterday and the problem started. I waited till I got home to see if would start playing again and it wouldn't. I just tried before getting online and nothing. I took the sub out of the box and tried each coil seperately still nothing. Anyone have any ideas as to what happened. Can you burn the voice coils or lock them up by unloading the sub? Im totaly lost on this and dont want it to happen again, need to get educated please help!
