    How does a Brahma 10 fair in small enclosures? I know it says down to .25 cu ft, but how does it really sound in something that small?

    The reason I ask is because Im not sure that I can fit the two 10w7s and the 3 amps. So I am possibly looking to do one 10 or 8 on the 40 side of the back 40/60 bench seat. I will still probably lift the seat, but it needs to be able to go under that part since the amps are on the other side. (before the lift I can fit an e8a under there barely after the lift add about 3 inches to that :) so I guess the e8a is about 7 inches :unsure:)

    Also I was even toying with the idea of doing a single Illusion Audio ND-10.

    What kind of space do the Eclipse TIs take? I didnt see it anywhere on their site.

    What about the BP 'saucer sub' is that out? How do they do?

    What about a trio or something like that of the Focal 5" sub? The only problem there is its only rated to like 45Hz, and the Utopias go that low, so Im not sure this would help since I just want something to pick up the bottom end although its pretty damn good just from the Utopias.

    Im kind of at a loss here since Im taking a step backwards....So I guess it boils down to what is a good/'high-end' sub that will work in a small enclosure? (power isn't a concern)

    Thanks,

    If I am not mistaken, a .71 QTC enclosure is .37 on the 10. So, take that as you will...

    To my knowledge Steven K has got the most experiance (outside of Dan of course) with the B10 on this board. With that in mind, I will leave the details to him.

    What are you looking for in this "high end" sub. Seems to me you are trying to fit a GIANT sub in a small enclosure. You may be better off fitting a smaller sub in the same or smaller enclosure.

    Actually my goal is not to fit a GIANT sub in a small enclosure, but to get a sub that sounds really good. If I were just trying to fit a gian sub in a small space I would just stick with the 10w7s that I all ready have.

    I ask about the B10 because on Adires website it says it can go in a box as small as .25 cu ft so I was just curious about that and how it would sound. Honestly I would have thought it would have sounded more like a midbass driver in something that small, but I dont know.

    I wouldn't councider the ND subs, the 'saucer subs', or the 5ws GIANT subs by any means in fact they are the complete opposite.

    As for the TI, I couldnt find the specs on it, which is why I asked.

    The reason I bring up those subs is becase they are something that I know a little about, and I know they are good subs. Yes, I would perfer a 'super sub' but I dont know that I can fit it, which is why Im looking around and trying to find out what else is out there since its been sometime since I have looked at subs.

    Basically I am open to anything you can throw out here....

    Not saying thats your goal. Thats why I asked what you wanted out of the sub. You just happened to mention some very large subs and I think it might be easier to fit a smaller sub in the same box to get more air space.

    IIRC the ND 10 needs about 1 cube for .707.

    Ok, what happens when I sub is in too small a box? Will it just not be as loud... or will it cause some of the notes to sound distorted and stupid. I have never been able to figure that out.

    It will sacrifice a lot of the low end. It can also give you an artificial peak in the frequency response. It will also decrease efficiency.

    Ok I will explain more. By going with a smaller enclosure you will lose the amplitude (the volume) of your lower frequencies.

    It will also give you a peak throughout the rest of your frequency response. Normally for good sound quality you want a nice flat frequency response so that each frequency plays at the same volume. But with the small enclosure you will get a peak so that some frequencies play louder than others.

    Efficiency will be comprimised as well. This means that your overall volume will be lower than in a larger box with the same power. The good news is power handling will be increased you can use more power if you have it to get to the same volume.

    Possibly thinking about extending my center console all the way up to the dash and doing a 2 to 4 focal 5w2s with about 1300 watts on them. :) Any thoughts?

    Either that or doing myabe two and having 300 watts on them and stepping down the Utopias to 100 watts a side.

    So, regardless I will have either a 4.0 or 6.0 for sale ;) and 10w7s :)

    Overall net effect (to simplify things) It woln't go very low and it will sound "boomy" or "canned" (almost like it echos)

    Illusion Audio recomends .8 cubes...could possibly get off a lil' smaller.

    I like the idea of the cyclone, but it requires a 'large' enclosure. I may work towards putting the amps in the back doors, if its not too much of a PITA where I could put the subs under the seat OR leave the amps under the rear seat and do the console idea up front. I just wonder what type of sound that would give me..... :unsure:

    I think I like the ide of the 5ws but I believe its frequency response is only down to 45 hz where as the mids I have are rated that low and are playing 300 and everything below and are doing good, but it just needs a lil help in the bottom end.

    If it means anything, Tom Nousaine recommended a 0.2 cubic foot (yes, 1/5th of a cubic foot) sealed box as giving a flat to 10 Hz response in his Corvette...;) The Brahma 10 will thrive in anything from 0.25 to 0.5 cubic feet - ask Steven Kephart about his baby Brahma in ~0.36 cubic feet, sealed.

    Too small of a box does suck. I once had my 10K in a tiny box. It had absoultely zero lowend. It was terrible, and there was no output whatsoever.

    Dan,

    Tom has the brahma 10? Also, I would just like to verify that the measurements of the Brahma 10 are correct on the website because in the space Im looking at doing this sub in, every little bit counts.

    I would feel much better going with a 10" opposed to an 8". Also I would definately love to put a Brahma in there if I can go with a w7, that is definately my second choice as I have said in the past.

    Also, is there any benefit from buying straight from Adire opposed to another Adire dealer online (like Seth).

    One more thing, in my quest to hear a Brahma I found a local shop that is an Adire dealer; however, it appeared to be more like a pawn shop. What is up with this? The name of the shop was 'Killer Audio' I believe and it is located in Baton Rouge, LA.

    Tom had the Brahma 10 for the review he did in mobile electronics.

    Also what issue was the review in? As I said earlier I would definately love to go with a 10 opposed to an 8 and I would love to have it be a 'super woofer' too.

    It sounds great, except for one thing. I noticed a large peak in the upper bass frequencies just before it rolls off. Modeling it in Bassbox Pro showed the peak that I was experiencing (6 dB worth). That's why I thought Nousaine's recomendation a little odd.

    But that was with the Mark I. The Mark II is a little different. It models up much flatter, and recomends a smaller enclosure than the Mark I (i think .707 is .31 cubic feet instead of the .6 of the Mark I). I really haven't done much listening with the new one yet, but I haven't noticed the peak as much. One thing I did notice is that it is louder. That could have been because I went a couple months without music, but I don't think so. I wouldn't expect the small amount of added excursion to make an audible difference, but it seems to have.

    My complaint: it is deeper than the Mark I. It barely fit under my dash, and I lost that little bit of room I used to have above the magnet. I was a little affraid for the surround when I put it in. It's in there and working, but I don't know if I will be able to get it out of the enclosure without tearing the surround. :eek:

    But boy does it look awesome in there. I so much like the new looks better than the old style. Plus with the superior audio performance (at least in my case), I am very happy.


    :love: , but with one of those being the Brahma.

    5ws is a great woofer for midbass PERIOD. Focal really didnt do anything special with those. They have a great reasonance around 60 hz. thats about it. As far as handing power. THEY DONT. they have very very light cone single spider and are very hard to control so you need one hell of a clean amp. A co-worker of mine has 2 of them in his mini cooper with about 125 going to each. He has blown the dust cap off them3 times now lol. Sound good in his mini cooper in reguards to full sound he just has no low end which to me takes a big emphasis away from the sound. Not tomention when he has a set of 6.5 utopias in his doors. Poly kevs i the rear and 2 5ws for subs his midbass feels like theres a drum in your back seat and not up front where it should be. These should not be used for sub bass. Koda's sound Better IMO as a subwoofer
