    Re: Duellati Build

    No problems, I think you worry too much. With epoxy base and then primer it's sealed put it out in your crazy hot sun for ten min and all the moisture will be gone -- Mikers
    We'll soon find out -- these would definitely benefit from a bit of color sanding and polishing. I'm annoyed with myself for repeating a mistake I made on a previous paint job -- I have a 50 gallon compressor, and I usually turn it off overnight. Forgot to turn it back on the next day and started spraying with the air in the tank, so after a few minutes, the pressure dropped. I got some orange peel (and overspray trying to fix it) here and there. I'll be off to the paint store on Tuesday to find out what they recommend for the product I'm using.

    Soooo, I'll get a chance to sand and polish. I'll post more photos later...

    Get some OC703 or Roxul mineral wool and place it up against the interior walls. Those products will do a much better job. -- Pete Schumacher
    I don't doubt that the Owens Cornings 703, or the Roxul mineral wool, is a more certain choice (widely approved by experienced builders). I will probably use some in the future, but it's not on the shelves at our Home Depot or Lowes Stores here in the Phoenix area. I'll need to find a local source. Thanks for your suggestion.


    Wal Mart mattress topper? They're actually quite effective--so much so that I've had to remove pieces of it from the inside of cabinets because it overdamped them. -- Paul Carmody
    I've noticed that a lot of builders are using the mattress topper -- I'm relieved to hear that you like the stuff, or at least consider it to be an effective dampening material. It's readily available, low-cost, and it installs easily. That makes it an attractive alternative...

      Re: Duellati Build

      Here's a photo of one of the finished Duellati. This really is a great little design -- I'm very impressed with these. I think they're attractive and their diminutive size makes them especially suitable for Home Theater setups where minimal impact on the overall decor is desired. Mark's design really does meet both goals -- unobtrusiveness, and excellent sound quality.



      I'll post a few more photos later..

        Re: Duellati Build

        Ron, those look Fantastic my friend! I havent been around much in the last week or two Ive been pumping things out in the shop getting ready for vacation next week and low and behold look what we have here! Great job as usual on your part and Im sure they sound as good as you say. On thing I would like to suggest to you is , I just read in one of your post where you were sanding your primer you said you had I think 4 or 5 power sanders but you still hand sanded because you were worried of taking off two much where you didnt want to. Here is a link to the sander I use when Im finishing a painted product espc when Im doing a "Piano" finish

        http://www.nolansupply.com/bysubcate...lse&specs=True

        It vibrates in a very fine micro circles and is very controlable and when starting w/ a 400grit or higher wet/dry paper its hard to screw up. It also has a air control valve that you can adjust to almost nill untill you get the feel of it. Its a little priceie but worth every penny. Im still trying to find the time to do the thread on the "Piano" finish techique I was telling you about , Ive done the work and took the pix , just trying to find the time to post the thread, but in the thread there are several pix of this sander and what it is capable of . It realy saves the wear and tear on the wrist and elbos. Great job my friend. R.K.

              Very impressive and gave me a lot of ideas for some projects that I want to do. I am a novice speaker builder and this type of post is so helpful!

              I have a good shop and decent woodworking skills, for me I need to learn the speaker dynamics, crossover, and sound analysis.

              I am trying my best not to rush into these projects either. I just built a set of BR-1s and really enjoyed it. They aren't done yet either and I already am shopping PE for another project.

              Love the mention of the WAF - that is a big one for me.

                Nice to hear from you -- thanks for the compliments. WAF is, without a doubt, probably the single most important design factor in the real world. It doesn't do much good to build a world-beater, if you're going to get more noise from your wife than you'll ever hear from the speaker. It would appear that you've been smitten by the speaker-building hobby -- that's a good thing...

                The Duellati are a nice design, easier to fit into your living space than most -- mine have made their way around the country a bit and have benefited from refinements suggested by a couple of respected designers, Wolf and Jeff Bagby. I haven't heard them since -- they're hanging out back east, hoping to get some exposure, I'd guess. Mark65 is the original designer.

                  Hi Soundlike -
                  Your box drawing shows 1.5 inch ID vent. Mark's writeup calls for 2 inch ID. Which is correct ?
                  Thanks, Chuck H

                    I didn't notice that in his drawing, but 2" is correct, and is what he put in them. They just got back from Dayton, and are in my living room right now. Just to make sure, I measured them.

                              Thanks for the tip about the error shown on my drawing. I'll get that corrected ASAP - wouldn't want anyone to build a set with the wrong port.

                              Note: After the comment from a builder regarding confusion about the port size, I reviewed my drawing this morning. I can see where the confusion came from -- the dimension shown over the end of the port tube was for the internal dimension (height) of the box. The port ID wasn't specified in the drawing, so I moved things around and labeled the port. Hopefully everything is clear now.

                              Thanks everyone for the compliments, and thanks to Mark for the design. Can't wait to hear them again with the refinements made by Wolf and Jeff.

                                Jeff just measured and listened with no complaints! ;) That was after I made the adjestments for Mark and used a couple handfuls of stuffing.
