    For those who don't know I currently have 2 Kicker L7 15s in 6.4 cubes tuned to 31.5 hz, Orion 2400 powering them. ( go to My Webpage) )

    I just installed my front stage and honestly think I could do better in the SQ for the subs. Should I go ahead and get 2 15As?

    I want about the same SPL (more if possible) but I want SQ... as much as possible.

    Thanks
    :bye:

    /hehehehe :p

    Sorry I can sell them for $300 each to people at my school

    Will the XXX 18 sound good in that box? I wonder because the graph is pretty peaky...

    Not enough info for an accurate responce ;)

    We try to be more objective and honest in our answers here. We are not about the flavor of the month, and even with so many people here being affiliated with Adire we are still honest enough and mature enough to respond according to the options given, rather than throwing in blatant BS totally outside the realm of one's proposed choices ("oh, oh, you need 6 Brahma 10s, even though that was not one of your choices and we have no idea what you want out of this system" :p :rolleyes: ).

    Unless of course you were proposing Funky Pups in your competition SQ install, then we may be so inclined as to speak up :p .

    So if you are disapointed in the lack of responces, maybe you need to consider this... The answers being given here are well thought out, and along the lines of what you are asking.

    Give us some more information regaurding what YOU are seeking out of this install. SPL, SQL, some design parameters (crossover points, subsonic filters), what vehicle, what do you like a driver to sound like, what music, etc.

    With that I am sure you will find some more answers being brought forth.

    Wow this place IS different that CAF :p

    Ok...

    I want it to sound really clean. Like very little audible distortion. Kinda punchy bass, but very smooth response (yes I know what this sounds like ;) ) I want the bass to go a low as possible.... subsonic is good. My crossover points are probably gonna change. I'd like to set my HPF for my mids at around 60 hz so the subs should stop there. I want this loud also! As loud as the L7s ;)

    I've heard plenty of W7s and W6s.... I like the type of SQ out of a sealed W7... just smooth and punchy.... But louder than the L7s.... ;)

    BTW I actually have around 8.5 cubes for the box.... so the XXX 18 is sounding the best right now. But can it take 2400 watts RMS though ;)

    Thanks fellas
    :kiss:

    You want it as loud as the L7s? I'm not really sure you will be able to accomplish that with the proposed installs. The SD of the L7s will dominate the others.

    My feeling is the 2 15As ported will be the closest of the proposed set-ups. Ported being good for a couple DB and the acoustic coupleing of the drivers being good for a few more.

    2/3 of the way down is a fair referance calculator for you. I might suggest plugging it in and seeing.

    I just don't feel the XXX 18, by itself in that box will be able to hang.

    All will sound great and all will get louder than 1 human could possibly stand.

    I personally would go for the XXX18 sealed, as the shock factor of sealed output and that big ass woofer would be priceless.

    I think in reading what you are looking to accomplish however, that the 15As might be a better fit for you.

    well the A's are gonna be somewhat expensive. I think the L7s are really not reaching their full potential to begin with. I want this new boxes ports to fire up into the empty speaker holes in the rear deck. This new box placement and direction (firing forward and completely sealed off from the rear trunk area) will definitely make any of the ported choics "seem" louder to the person in the car than the L7s are now.

    I'm thinking XXX though on this one. Because after figuring I can do 8.5 cubes it'll definitly beat ass :p Plus the port area will be close to 200 in^2!

    Would looking into 2 XXX 15s be a more feasible choice? It'll be awhile before I can afford that though ;)

    BTW won't the XXX 18 displace more than my L7s do now? Along with the fact my L7s are reaching anywhere near full excursion :blush:

    Thanks for the help BTW :bye:

    The surface displacement goes to the L7s. Remember that full excursion will be difficult to achieve at tuning in a vented box, so surface area is more important than Xmax. Also you are not keeping in mind that multiple woofers create acoustic coupleing, which is good for about 3 Db itself.

    I like the XXX too, don't get me wrong. It will get way lower and sound way better than the L7s will. But I see you suggest a couple times you want it at least as loud, which is where my suggestion is coming from.

    With 8.5 feet it will get humping damn good. as far as aiming the box... lookat Eddie Runner's take on it ;) .

    Isn't acoustic coupling a myth?

    I was thinking about a SoloX too :p I know I know they're not SQ subs, but I just can't resist SPL :blush:

    Someday I could upgrade my 2400 for like a 5000 watt amp for the SoloX :p But I do understand that the As would fit the bill, they're just around twice as expensive.

    What would the XXX 18" peak at SPL wise in 8.5? How would I go about figuring this out. I'm guessing 45-55 hz... I'm thinking about removable ports so that I can have my SPL when I want it. Thanks for that aiming tutorial BTW!

    That aiming tutorial....

    I really don't understand how front firing can do that. Especially when the box is sealed off from the rest of the trunk like I wanna do. Can you help me out on this one?

    SoloX's are duty built for one useful thing, and that useful thing isn't very useful in my region - the 2 people running them get their tail whipped by L7's and other products at almost every show...

    Last SPL install that was eD based I had the displeasure of dealing with did 157+ with two of the 15A's. If that's not enough output, you need to rethink your entire purpose in life, because if you want to hear by the time you have grandchildren that isn't the way to go about it.

    :p lol

    I suppose :)

    But I still want louder... A's have displacement capablities no doubt ;) I'm probably gonna go with the XXX 18... simply because I'll actually make money when all is said and done :D

    As I told you a couple weeks ago when you brought this up, I do not think the 18XXX will be as loud as your L7s. The cone area of the L7s is so much greater. Excursion is limited in a ported app so cone area means quite a bit more. Xmax is mostly useless for figuring a loud ported design. It only helps you mostly below tuning by letting the sub move furtherwhen unloading and you will not bottom as soon.

    If you look at the excursion graph of winisd pro with your current app and your proposed app you can look at the excursion of your subs.

    If you are serious about the SoloX drop me a PM. I have a supplier that can get me the woofers and recones too.

    As far as the XXX and SPL... the combonation of the 2 has me thinkng you need to talk to Marshall (black00). Marshal is a tried and true competitor who is always willing to help, and imagine this, an RE dealer ;) . He will have more experiance with the XXX and SPL than anyone I can think of off the top of my head. Maybe he'll answer here, if not, drop him a pm.

    Acoustic coupleing is far from a myth ;) . Porting an enclosure utilises acoustic coupleing, loading panels, and Eddie Runners tutorial are also good examples of acoustic coupleing. It is simply the reinforcement of a soundwave with a second soundwave.

    When we tune a box to a specific frequency, we make the port length "X" long so that when the wave of pressure escapes the port, it is at exactly the same time as the woofer on it's forward path. We are creating acoustic coupleing at a specific frequency. Essencially we are creating a "second speaker" that is most efficient at tuning.

    I remember ;)

    I was just trying to finalize it in my mind ;)

    But it just doesn't make any sense how everyones telling me just keep the L7s... I can't be hitting more than 150 with them now. And I'm sure with 8.5 cubes I can do better than 150 with other drivers.... At least I thought I could :blush:

    Also with only 1 18... I'll be in a different class if I want to compete in the Spring... ;)

    that is also some part of the motivation :p

    Why not Build the box for the L7s?

    It will be a lot cheaper than buying new drivers. It should play lower(depending on tuning of course) and it should be louder. Two of the things you wanted. All for the price of wood, glue, and however you want to put them together.
