    Looks nice, but what are you gonna do with it? Are you building a 3-way design? Which drivers are you using? What is the purpose of the open baffle? What is the size of the cabinet and what specs do you expect?

    Yes a 3-way design using Seas alum/mag tweeter/ 5.5" mid and poly 8' woofer. The cabinet is not finished so the top is open yet. Woofer box seperate from tweeter/mid.

    Speaker will be bi-ampable with woofer x-over on bottom and tweet/mid x-over on top in enclosed compartment. I am putting in an access door in rear top.

    The cabinet is 38" x 11" x 16.5 deep. X-over being designed by Madisound (LEAP) as we speak.

    Where did you get those cool looking "feet?"

    Is the cabinet your own design or are you using an existing design?

    Let us know how the Madisound LEAP thing works. That's a nice service at a reasonable price.

    The design is from Kharma. It will end up looking like one (or a combination) of these.

    I've used Madisound before with great results. $40 for a 3-way and $25 for a 2-way design.

    How are you going to do the top? Steam bending? Kerfing? Lotta MDF + laminate?

    i'm going to frame it up and cover it with alum screening then Bondo. I'll make a profile form to keep things in line. Finishing not decided on yet.

    I've never used bondo in a structural sense- just as filler. Will it resonate? Are you going to add some braces front to back to fix it to?

    I first rough out the walls with hardwood or sand-filled pvc then cover with screening before bondoing.. The inside walls are sprayed with undercoating and then lined with 1/2" carpet padding. Makes a heavy and very solid enclosure.

    Btw, the top is sectioned off from the woofer cabinet. The pic below shows more detail. The x-over for mid/tweeter will mount on the board with the slanted front section which slides into aluminum rail and secures with 2 thumbscrews. Rear baffle will have an access door.

    Very nice work! The photo's on the website are also very cool! The design where the cabinents are angled would make me crazy. I felt dizzy just looking at them. I'm interested to see the finished product and how you like the sound. Good luck!

    hah checked out that karma site. Trying to clone them, eh? Do they use the same drivers?

    Great work so far hopefully you'll get some good sound out of them =)

    Got three questions --

    It looks very professional. What kind of background do you have in building furniture or cabinets?

    What did you use to get that shiny black coat on the speakers?

    Once you're done, what is the total estimated cost?

    1) None.

    2) Front and rear are polished lacquer. Sides are reverse painted acrylic panels.

    3) around $900.

    All Seas drivers.. P21REX poly (now disc.), 15RCY and 27TBFC/G. Would have gone with 2 x 8" or a 10" if I could do it over. I may change out the woofer to an alum driver. Considering M8a which I hear good things about.

    A lot cheaper alternative would be going with dual Dayton RS225s. They're cheaper and better than the Hi-Vi. You would be using them for bass/BSC duties, and they absolutely excel in that area. They have better low-end distortion measurments than even the Seas Excel drivers, which run almost $200 each! Also, they look absolutely amazing and would fit in extremely well with your cabinets.

    Your tweeter is top-notch, probably the best tweeter you can buy for under $100. As for the mid, if you want things to match you could go with another Dayton RS driver, which are almost as good as the Seas Excel drivers in that department. However, if you want to make a statement, go for the Seas!

    Well I finished both of them and my concern about lack of bass is gone. Moving them around a little and removing most of the polyfill helped. I am very happy with the sound from them.

    Also putting them on the bases I made probably helped too. I ended up making the bases out of 2 layers of 1/2" mdf. The single 3/4" mdf wasn't going to be strong enough. The sandwiched ones are incredibly strong.
