Sub not hitting right notes

I'm at work on my cell but for the size its one 12. Sorry for not including that in my first post since everyone is asking.

We need to know the sub size, the actual problematic frequencies (get your *** out and find out or at least give some song titles and what note in the song), and your crossover settings.

It might be an enclosure problem but it's hard to tell due to us having no clue what "wacky" sounds like. Be more specific if you really want some help.

Too small of an enclosure will cause a hump in the upper bass frequencies and usually cause a lacking low end. If your problem is not a boosted top end, I really doubt it's due to the enclosure. You may be experiencing a widespread problem with the XXX -- lack of upper frequency extension.

lol thats exactly what i was thinking. since when does a smaller box make the low end shine and upper end ****? ****ing ca.com man

Exactly how high in frequency are we talking? If you're expecting a bunch of output above 60hz, GL. What are you running up front? What are your xovers set at?

exactly what i was thinking and exactly why i switched subwoofers about a month ago.

i had the same problem with my Treo SSi. it had a very large peak in the bottom end and lacked both output and quality in general in the higher frequencies. in my case it might have been a small result of the box but i think it was mostly just the way that particular sub was.

the XXX is (from what i have read) known to be a lil bottom heavy.

I'm glad someone figured that out.

To the OP. You probably didn't do anything wrong, it's just an attribute that the XXX has. I think someone said it has to do with the huge coil they have, raising inductance, which will affect frequency response.

yes, that could be. same reason you got rid of your and switched right?

Ok thanks for the inputs guys so whats a good way to measure the frequencies and so forth? I dont have the tools to do so since i took it to a shop. I should also mention that everything in the car is bose factory system. Just to throw that out since i heard that may cause problems i guess. The settings on the amp looks like the frequency knob is set below the first mark (so i dont know if its set at ~80hz or so) , while gain is at the first mark, and bass boost was up but i turned it off. Theres also a bass remote which is somewhat turned up. Sorry for not be really specific since i am still learning about all this so all your info does help.

Example of songs i played that sounded weird was like Unk - 2 Step and Hold on Hoe, songs would "bump" for a second then became soft (like not getting loud) then seconds later it'll "bump" then repeat. It wasnt consistent while listening to Danity Kane - Showstopper, throughout whole song it sounded fine. Hope that kind of helps.

XXX's are notorious for lacking midbass output (>60hz). Them being 'bottom heavy' would mainly be accounted for by the enclosure size/type/alignment, and possibly by signal processing.

The bass cutting in and out like that does not sound like a lack of upper extension by your driver, it sounds like your charging system inadequately supplying your amplifier (possibly). I own xxx's, they dont sound 'weird' in the midbass region, they just dont have much output up there.

I dont recommend (the orig) xxx's unless you have a substantial midbass setup to mate with it/them. If you do have a solid midbass setup, you will love xxx's.
