    Nice looking job. How's it sound? What's the 15" driver?

    Your pictorial answered a question for me on the use of a pocket hole jig.

    Great work. How about reviewing it for us when you've given it a good try out?

  6. Very Nice!
    I have 2 questions: first, what does it weigh?
    Second, how does it sound?
    I really like cabinets w/o crossovers and tweets! How does it cover the sonic spectrum?
    Where did you get the plans? or did you design it yourself?
    great job by the way!

    thanks, man...
    ok answers:
    first, I had three goals
    1) much lighter,
    2)fits in my trunk
    3)sounds better than my old Yorkville 400B combo

    It is WAY lighter than even the 400B cab without the head in it. I haven't weighed it yet but probably under 40 lbs. The driver is an Eminence basslite C2515 neo. The combo's driver has a giant magnet.

    I've always played with a 1x15 combo amp. We play classic rock in bars and pubs. I've never really gone for tweets. I also have an SWR 2x10 but never felt it was necessary. Sonically, this cab sounds "wider" than the YV driver. On top: The C2515 is quite a bit brighter even though I play with flats. On bottom: My combo starts rolling around a G (I'm playing a 4-string bass). So, on the E-string...
    G: still ok,
    F#: hardly notice,
    F: noticable now
    open E: really bad roll off and tons of classic rock tunes are in E.

    Of course I didn't notice any of this until I was able to compare the two. The new cab is very consistant down through an open E. Even below that - If I detune a D-A-D-G tuning for something like Nirvana's Heart Shaped Box (my bottom is then Db) it's still pretty strong.

    The 400B was a pretty loud combo, this is a 4-ohm speaker instead of 8, so it is quite a bit louder when comparing.

    I used WinISD for the box design. The box is roughly 87 liters. I only set a 15" depth so I can lay it driver-up in my trunk and a 24" width. The WinISD set the height (almost 19").

    All the parts are from PartsExpress, wood from Home Depot. The box is painted Benjamin Moore 1673 (Vermont Slate). I forgot to order black screws and bolts, so all the hardware is stainless steel from the neighborhood hardware store. The speaker grille stand-offs (spacers) are just nylon spacers that I colored with a Scripto perm-ink marker (LOL).:smug:

    I'm dying to play it out - haven't done that yet. I was planning on building a matching 4-ohm 2x10 cab and switch to a Crown XLS402. But, before expending that cash I'll roll with this for a while and see how it goes. I've got a couple of house projects in play and I have to return my attention back to the honey-do list for now :D

    Very cool. Did you fill the box with any type of sound damping material?
  10. MojoBenny


    Dec 14, 2007

    You do, the interior of the cab must be 100% lined with an inch to inch and a half of open cell foam or polyester batting, if not the midrange response will be quite horrid.

    No. Look at the pics. It has a shelf port.

    There's a shelf port on one edge of the front baffle.

  16. Great assembly. Your cabinet looks solid enough to throw down a flight of stairs and still gig through the night. Kudos!

    I couldn't tell from the pics, did you use glue on the joints or just screws?

    Congrats man! I love the color.

    I built very similar cabs using the same speakers. Mine weighed in at 29 lbs. each. But I used 1/2" ply and braced it to keep the weight down even further.

    I definitely had to line the entire box (I used carpet foam). Lining it made a huge difference in tone!

    ok sounds like good advice and I'll add some fill next week. I haven't weighed it yet. I'll do it when I get home. :)
