Does it sound boxy/muffled in Midrange since there's no vent hole? Has anyone actually cut a hole in the back thus helps it sound more open &amp; transpar

Not at all. This speaker sounds wonderful right out of the box. I bought one as a tester, and liked it so much that I have now upgraded my entire front soundstage to BIC and plan to eventually replace my side and rear surrounds with them too.

Did you ever find an alternative to the BB2001? Funny, I just bought the im600 today, and it still had the slip in it for the BB2001. I would like to buy a subwoofer for it though, so let me know :) That goes for anybody reading this, too!

Mine is in my semi so it'd have to rattle fairly loud for me to notice. In general it doesn't and seems ok. The only negative I've seen is you lose direct heat or cool on the vent you use. It still comes out, but the unit blocks it from you directly. Basically a minor inconvenience to me

I have a full enclosed box and it sounds great. The design to my box was custom, since for this size of sub, it is a must. The thickness of the box is 1 inch. My sub I have installed in my Baja power boat, so for this reason, I had to have my box made with special marine grade compounds to prevent expansion and distortion to the box. But if you plan on having installed in a vehicle, you shouldn't have an issue with that. One suggestion, this sub does require a lot of power, so I would highly recommended at least 750watt HD amp from JL audio.

To be honest its a little on the noisier side. If u put it in an enclosed space or box it does eliminate some of the noise.

If your Spkr's are vented, blocking the vent wii reduce the Spkr's bass output and it will sound somewhat muffled or diminished. This foam would be a rather expensive fix to plug a hole. Other option's are poly fill or some kind of insulation or foam laying around the house

It helps of you know what your inlwt and outlet size is 1st off and then u need to know how ur exhaust is offset like is it center inlet and offset outlet but it should just replace your stock muffle. U have have to get a reduce for the inket side?? Its been awhile since I did mine cant really remember. It doesnt have great sound at 1st but once u get past break in period sounds great for just a muffler ppl ask me all the time what exhaust I have

sounds kinda crappy to me =/ it gets that crackling noise if it's too loud/heavy. i'm no expert though

Any sub sounds better in a vented box. Even so, I made a closed box for the small space I have an it sounds great.

I had a different shallow sub and worked fine. I then got that same sub tw3-d4 and its about 13" diameter so had to cut out the hole. But I found no better box. Sounds good

I just cut a hole and mounted them with no speaker box. They sound fine to me. some people and installers have recommended adding insulation material to help these speakers sound better.

My personal opinion, ported but that's just me. I like deeper richer more powerful bass, but it currently have 3 of those same 12s in a sealed box anew they still hit hard as ever. However I'm making a ported box this summer. Overall, it's all about the kind of bass you like, if you want more clear bass go with the sealed, if you want the thunderous boom go with the ported. Hopefully I helped !!

I down graded from 2 Fosgate P3's to a single sub to get a little bit of trunk space back (2006 Sentra). I think the sub sounds damn good for just one. I have it in a 1.25 sealed box, hooked up to a Alpine 500W mono amp turned only to half gain with a remote bass knob. I have nothing negative to say about the sub.

Same as the previous poster the silencer goes in pretty tight, however I would recommend that if your going to remove it do so with a brass drift pin or another softer metal or you will bend/mangle the unseen end of the silencer...I am picky I like my metal to look the way it did when I bought it. Also I sat mine 4 inch side down into a hole i cut into a piece of plywood over a 55 gallon drum, to ensure that when the piece could actually come out because it is pretty tight all the way in.

I like mine. It does not rattle the windows but I do get a surprisingly deep bass from such a slim package. It will not quite fit under my seats but it should fit under some which would be interesting. I like the output remote its nice for on the fly adjustment. Cant compare it to the other unit as I have not seen it.

James, Yes it sits on top of the factory sub so it muffles the sound a bit, but without cutting holes in this the the only way. Thank you!

Im not sure of the tuning but i put an alpine type r in it and it was not loud at all. My bassworx box i bought years ago was way better and about the same size. Finding a good pre-fab is tough. Custom Built is the way to go or builf one yoyourself. I would always go slightly larger box volume than manufacturers specs. I have a DC audio xl 15 in a custom box at 5 cubic ft. DC reccomends 3.5. I tried a prefab at 3.2 tuned to 32 hz with a labyrinth port. It was garbage. I dont know the tuning of the q power but i wouldn't. Buy it again.
