08-11-05 Thanks for the reply,parts on order. :T
17-11-05 Fixed inductor problem!
02-03-08 I have a question; last post below...
Hi All,

Well I finally finished my Audax Ht (except for surrounds) I decided to go with these as the price was fair for my "first" DIY project and Audax still has parts available. I have yet to build the surrounds(three) as I have the parts but the weather is getting colder for the unheated garage!
I had on planned on using two 62l sealed shivas as "speaker stands" but my wife nixed that idea quickly when I brought them into the family room.(14'x18')
Anyways,I am extremely happy with them;very "clear" compared to my ol' Athenas AS-B2s. They don't exactly have enough bass punch but as ThomasW said," what do you expect for 3mm xmax!"
Here are some links to them:

Wow. They look great. Nice work Dean!

[KeithM]

I wish I had wordworking skills that good.

[DeanP]

Thanks for the nice comments :T ...I usually build furniture, so these boxes were pretty easy comparably. It is getting them square that is the hard part as I just have a bench type tablesaw that only cuts to 12" wide.

Wow nicely build, which Audax woofers have you used?

[DeanP]

The woofer is the AP170Z0 and the center channel also adds the AP130Z0 with TM025F1 for tweeters all around.

[DeanP]

Help!

I was looking at the Modula MTM's x-over and was comparing it to my Audax main's x-over and I noticed that the first inductor (for the woofers)was larger compared to mine from the Solen site here. 8O
Then I brought up a PDF file I also have of the x-over and found that Solen seems to have put the wrong value in! They have on their site a S16.18 where the PDF file and also at Madisound, they have a S161.8!
I'm going to order the correct inductor but I was wondering what effect this is having on my speakers now?
BAD SOLEN :M

[ThomasW]

They send you a .18mh inductor for the woofers?

Yes that would have major impact on the performance. Since the highs aren't being filtered out of the woofers it would give the impression that there wasn't much bass.

[DeanP]

No, they didn't send the wrong one , I ordered the wrong one ,which I got the info off of their(Solen) schematic from their website. I never really looked too hard at the PDF file that I got elsewhere on the web. I kinda thought when I recieved them that they looked a little small compared to what was going into the center channel.
Thats why they call us "beginners"! :roll:

Since the highs aren't being filtered out of the woofers it would give the impression that there wasn't much bass.

Exactly, but I thought there wasn't much bass due to only "3mm" of x-max.
Thanks for the reply and I guess it really wasn't a big emergency issue but then I was second guessing that maybe Solen's site was correct. ;x(

[DeanP]

My Audax are even better now!

Well the 1.8 16 gauge inductors came,so I just finished them last night and now they HAVE BASS! :T

It was a bit of a job(but not too bad) to remove the drivers to get at the x-overs as I siliconed them in. I replaced the incorrect inductor with the correct one and while I was in there, I changed some wiring on the x-over that I wasn't happy with. I fired them up this afternoon and what a difference. I have bass plus they still are "crystal" clear as they were before! I'm definitely learning...

My next DIY (or at least my thoughts are) will be to make an amp. Does anybody have any links where a person can buy a kit?

[DeanP]

Moved question to new thread...

[peter_m]

DeanP,

do you use the mains for music listening? If yes, do you find the tonal properties change allot when you get up and move about in the room?

Peter

[DeanP]

I use them for both , ht & music. The tonal properites don't change a lot when I move around the room. As you can see in my first post, my room doesn't really allow me to move around much! Ha! Ha!(see "set up close up shot" photo link)
