franlofter,
In what part of the country do you live? I have some sonotube left and if you're close, you can have that.

madisound.com seems to have some descent subwoofer kits. http://www.madisound.com/sonicraft_sub_kit.html

I haven't heard any of these. Anyone got any opinions I'm thinking about buying one without the cabinet to try my hand at building my own. I've built many car boxes. I think building cabinets for a 5.1 system is in my near future. I plan to also use the Audax kits.

By the way this thread is awesome. Finally read the whole thing. Wow guys, great accomplishments all over the place!

hi
any advice on putting 2 two way seas .
they will be as 2 speakers <2way each> in 1 enclosure. each 2way has its own xover .
they will be connected to amp as L\\ R speakers.
i did this to conserve space. i`m going to have to rearrange layout for all speakers to get the balanced sound.

thanks safaa

safaa,
Is this what you're looking for?
www.ellisaudio.com
Check out the 1801B. IMO, you don't need a speaker that good for HT. I'm building these for my 2-channel stereo system. Also, Madisound has several Seas kits

Can someone please post the complete drawings for the Audax center, main, and surround speakers. I am hoping to get the cabnet drawings as well as the crossover skematics with parts list.

Thanks

Well, I was a Braves fan long before moving down here. I think that most Braves fans were rooting for the Cubbies.

A note, since it may help some of y'all... I've come across a couple articles on glues and the like recently and figured I could share.

For this type of work, good old white Elemers all-purpose glue may be the best choice! It's the same stuff as the yellow carpenters glue, with longer drying time (more room for you to fidget) and no yellow die - it dries clear. However, it's thinner which makes it less useful for filling gaps and for general carpentry (where it was designed to be used!) For fine, close fit joints (cabinet-making, and the like) the white glue works great.

Gorilla glue is a completely different type of glue, and may actually have a weaker bond when working with MDF. It's designed to be used where weatherproof is key, and it needs some moisture in the wood to really bond as well as it can.

For J. L.'s sonotube issue, I would have pondered through-bolts (much like retaining wall anchors work) or, as he did, not use MDF.

Though, I'll be installing an IB manifold sub. Strong response to 5hz just tickles my fancy for some unknown reason. And, of course, opposing drivers mean any big forces end up being cancelled out.

I need to find a good built-in speaker solution though. (This, for a home-theater).

Jeff,

The complete plans for the Audax home theater speakers were posted in message 363 in this thread. But there are a few minor errors in the plans. Do a search in this forum for "audax" and you'll find a thread with fixes for the plans.

Audax.com does not seem to exist. I am looking for the detailed construction drawing for the complete audax HT line.

Anyone?

If you order the parts from Madisound, you'll get everthing at a 10% discount. They'll even assemble the XOs for you (correctly). I say that because the Audax site has a mistake on the XO. Just go to Madisound.com and you'll see it. It all comes in a very nice package with instructions and schematics for each speaker. They even include a couple of bags of Polyfil, foam, screws, posts, speaker gaskets, speaker wire and even solder. I didn't use the foam and followed JL's lead by using eggcrate foam. I also used larger Monster XP wire inside and a set of nice gold binding posts from Parts Express.

Jeff's right, and that's exactly what I and most othes in here did - just give Madisound a call and they'll hook you up. I was initially going to solder my own xovers from their schematics, but I discovered that it would have cost me MORE to buy everything separate than what they can get it for wholesale, so you'll even save money doing it that way (having them do the assembly work on the Xovers). Word of advice - if you're building the cabinets yourself and aren't an expert cabinet maker, make the rear channel speakers first. They're smaller, less complicated and not out in front of everything in case you make some mistakes!

I can get the parts locally but being from Canada the currency exchange, duties, shipping I am not saving any money by ordering from the US.

CAD drawings of the cabinets would be great if someone would like to post them or send them to me pontiacgagt@yahoo.com

as for the crossovers, I have done electronics work and am comfortable tackling the constrution from scratch (actually I prefer if I built it myself).

Thanks

pontiacgagt,

Go to message 363 in this thread, and you'll find a PDF File of the complete plans, with a few minor errors. Do a search in this forum for "audax", and you'll find a message which lists the corrections. Go to http://www.hometheaterhifi.com and click on the DIY link, and you'll find an article on building the Audax center channel.

franlofter,
I built my cylinder sub for $300-400, I think. I guarantee you it sounds as good or better than a $1000 sub.

When it comes to smaller subs like the Rava, by the time you buy a good quality driver, a plate amp, and a pre-built cabinet. Then you do not end up saving much if any money over buying the same thing assembled. It's when you want to go beyond that, by buying the driver, buying the plate amp, and building your own cabinet or enclosure over buying a pre-built one, that you save money and get more than your moneys worth with your finished product.

A good 12" driver and plate amp should be around $250, add in about $25 or so for the MDF and such, to make a small sub cabinet like the Rava has. And you should be able to do as well as it for a bit under $300 total. But boost up either the quality of the driver and plate amp, or add in the cost of a pre-built cabinet/enclosure over making one yourself. And you will not save money over buying a Rava that's already made.

Face it, the just a bit under $300 price is about the lowest it will cost to start making a 12" powered sub, no matter how small it is. When you use a plate amp that will cost at the least, about $100, and a good driver that starts out at a cost of about $130. And you can really blow that price point by upping the quality/price of either the driver or amp.

Adire's "dealer cost" of all the components to make them, still probably allows them a profit margin of somewhere about $60-$90 per sub I'd guess. Even though it's pre-built for you, and selling for just a dollar under $400 for the cheaper version of it.

hi
i ordered a sub before i built mine, i though i won`t be doing right,
but i took the challenge,
that how much it did cost me to build a shive MKIII vented L85.
$40 plywood oak finished 3\\4 `` 4`x8 `.
$125 shiva driver 12`` MKIII.
$130 amp parts express.
$12 vented tube flared PE.
$15 4 bunn legs for the box.
$ 8 stain+ gloss+glue.
$50 for my friend for helping me.

for damping i used some old foam i saved form pc`s boxes.
so total is $380. plus total of 6 hours time.


now i ordered one from acoustic-vision.com that before i decided to build mine,
here is the prices without $130 amp without $125 drivers,
the price here it just for box and cut holes and vent tube
$265 for box, veneered.
$20 legs
$19 vent tube.
$55 S\\H.
so total is:$359 add $255 amp+drivers= $614.
i would saved $234 if i didn't ordered second one.

the best speakers I have ever built are a modified Sound Dynamics RTS-3. I just changed the enclosure and viola! It produces such an amazing sound! I have no idea why these cheap speakers sound so good.

I used to own Dynaudio Contour 1.3, I sold it since the SDs sounded more natural overall. I even did side by side comparison to the B&W Nautilus 805. Me and my friend were astonished at how close it sounded. Actually almost everything was the same except that the 805 had a little too much around the midbass and the treble was a bit too forward.

Just returned from the Dayton DIY event where Dennis Murphy shared his modified Veracity design. It features a hybrid tranmission line/ported floor-standing cabinet that allows the W18 to exhibit flat bass extention down to about 32Hz.

These are probably not good candidates to use with a subwoofer since the roll-off is so shallow it would be difficult to successfully integrate. But they sounded really sweet.

I will build a pair for further testing and will post further impressions at that time for those who may be interested.
