Hi, I purchased a pair of silver flute 6.5" woofers for autosound use but will not be able to use them at the moment. I also paired them with the dc28f-8 tweeter. I will not be able to install these and was wondering if there is an inexpensive solution to find an exclosure/ crossover so I can just use them as a bookshelf set.
Thanks
Thanks
These? https://www.madisoundspeakerstore.c.../silver-flute-w17rc38-04-ohm-6-1/2-wool-cone/
There are box suggestions in the spec sheets.

I have never built any enclosures, vented would be especially tough for me. Any recommendations for a place or individual that does such work?
Thanks
Unless you get a good quality table saw, cutting the cabinet is going to be difficult. But it is very easy to buy pre-cut cabinet of very high quality this day. Parts Express is one good outlet. Silver Flute gave some box suggestions.
The easiest way is to buy pre-assembled, pre-finished cabinet. You still have to cut the holes for the speakers. The 0.38 cubic feet volume will get you more bass.

If you are not going to do a fancy external finish, you can build one from knock-down kit relatively cheap. The only tool you need are wood clamps. The PE web site has some good video for the building process. But it has 0.23 cu ft only.

Find the vented port at the right diameter and cut it to length.

Now, the crossover is an entirely different matter.
The SF flange is really nice if the hole is cut just right, but they don't give you much tolerance.
The tweeter looks like a good choice, 1-1/8", that can be used down to 1,800hz although as keilau pointed out, finding a xo is the real challenge.
More on this later, but removing the dust cap is and inserting a wood phase plug for this $30 mid-woofer transforms this driver into a real contender.

John "Zaph" Krutke had tested and published the response and impedance for this Silver Flute. His evaluation of the Silver Flute is very positive.

It will take some work to create the FRD and ZMA files from Zaph's test data. It is very easy to find FRD and ZMA files for the Dayton Audio dc28f-8 tweeter and plenty of crossover examples (high pass). It may be a fun project to simulate the crossover for this combo. 😉

I think 90% of this advise is spot on. Those pre-cut and flat pack cabs are nice. But I want to quibble with this assessment of the difficulty cutting wood without a good quality table saw. I still own the Sears Craftsman circular saw I purchased in college to build my first speakers. That was over 40 years ago, and while I now have other high zoot circular saws and wood working equipment, cutting straight lines for plywood butt joints is cake using an inexpensive aluminum cutting guide/straight edge. Admittedly, back in the day, I required no small amount of Bondo to cover an errant cut or two, but it all got painted black or covered with carpet. No harm, no foul.
There is no speaker I have ever made that I could not have made with a $20 Harbor Freight circular saw and a $10 cutting guide. There is some loss of efficiency, but if you are only making a couple cases, I don't think that is a big deal at all. The expense will be in the blade and that is going to cost every bit of $60 to get through quality Birch plywood.

Bruce, there is no question that you can do a wonderful job with a circular saw. I am talking from my own experience. It takes more skill to cut a straight and smooth edge using a portable saw.
I tried and could not get the result I wanted. Thus, the comment.
Similar comment about cutting the speaker openings. While a jig saw can do the job, but a router with a Jasper circle jig is much easier to use.
podus said that he never built any enclosure before. I believe he is looking for something not too difficult and without a lot of investment in tools.
I am sorry your results were disappointing. And there is no question that table saws are good. So are bandsaws, router tables, shapers, jointers,.... One can accumulate a lot of iron over the years. But I don't think I knew any better back in the day, and I thought my creations were grand. And, when I discovered that Bondo worked as well on wood as it did on my rusting VW van, I was a happy camper.
What I lacked in craftsmanship, I made up for in the pleasure of making my own stuff. I may have lax standards but I would want to encourage everyone to take up the saw and work the wood. I will completely agree with you about the router though. In speaker building I think a router beats a jig saw hands down for most anything. They too can be had at Harbor Freight for $20. But routers and circular saws show up on Craig's List with regularity, keep an eye out.
I have seen those assembled speakers where the only task was to cut the front baffle and they were very nicely constructed and finished. If I were only going to build a few systems then that is the way to go.
That said, I love the smell of sawdust in the morning.

dollar for donuts - if I needed a starter tool the 12" miter saw is the way to go.

Box stores sell various pieces cut from full sheets, 2 x 2, 2 x 4 etc. Or as many know, they will cut on the panel saw for a $1.00 or something like that.
Podus, what part of country are you in? Fabricating small boxes is not very difficult, shipping them is the issue
