I am taking about a “Default Evaluation Loudspeaker”. Let pretend that all people who do SET appointed one single full-range driver: like some kind of Fostex of Feastrex… and all agree that the driver is placed dead center of 100cm by 100cm open baff...

I have built quite a few bass horns and found any thing over 1/2 inch ply wood reinforced is all you need, in front of your baffle. If you had ever built a few on your own and had the right equipment to test you would realize this, but when your a ha...

[quote user="Romy the Cat"]Now, a few predictions. Next year, if the Silbatone folks are no fool. then will discard the stupid Aporia and will come up with a new loudspeaker.

Kodomo,
A brief post about concerns. Feel free to discard it.
LF modules – are you sure that you want to go with ported
solution? You can model your boxes and use any good drivers but sonically with
port you will end up with bass that would h...

share only critical and warning thoughts not because I have nothing but critiques.

Mats, I must have missed something. What do you see in the Audiotekne photo that you ask after the bass box? My usual ADHD glance only took in a double-wall-with-double-cutouts front baffle(s), and the (small-ish) size of it; maybe some sort of BR ...

To me the big green drivers in the midbass horn look like old Siemens Klangfilm or Telefunken (or other German manufacturer) 10 inch units. Maybe 12 inch... I had a pair of 8 inch Klangfilm once and they do have interesting tone across a couple of oc...

II would like to pass a word of warning about the C-15W driver. I do not know this driver but it looks like it has dual voice coil. This might be a hell or blessing. On a paper the idea sound very interesting but unfortunately when I seen it it never...

Romy, have you gotten into where/how your MF driver breaks up yet? Given that the tweeter is actually made to go way down there, I am curious if this may be a case where 1st order XOs at 1 octive apart could work. Or, if not, at...

The only reason I don't have a giant WE system is that I can't afford it and I don't have room. I sold all of my WE and Lansing field coil gear to my Silbatone friend back in 1989, because I know he would never sell it, he was putting together a ser...

Yes, yes. This ooops thing is important.
For many years I happily listened to PHY KM30 fullrange in crazy
thin-plywood semi-open baffle boxes. And - apart from loud piano music
- they are really quite terrific. Very communicative and easy to get...

Tweeters Alignment - what is a bitchy subject! I was mildly complaining about it for years and during the last few weeks I complain about my own tweeters - primary because the very same issues of the imperfect alignment. This there is a derivation of...

I was wondering: if I lose my midbass and will use for now
my bass town to do midbass then how can I introduce lower octave channel of I
want to make a room civilized? For instance if I go do 2-4 Aura drivers on
transition slope then I will end up...

It looks to me that I will be able to live with my 6 driver
line array. Again no measurements were made but it is what it “looks”. Sound-wise it is very reputable and I just might
leave it as is. My current room is 6 larger to what I had in downto...
|

Maybe make a manifold and mount drivers vertically in push pull. No sagging, much less vibration. But I would not use fiberglass insulation behind the bass channel and remove any existing fiberglass in that area, replace with cotton/denim insulat...

Decoud,
There is nothing wrong in what those guys propose and there is nothing wrong in in-wall to mount drivers in infinite baffle configuration. In fact it very much interesting idea to build a custom room with a strange shape where wall most favo...

Greg, do you have any experience with the Eminence drivers?When the Audax PR380M2 I use (8 Ohm) became unavailable, Dick Osher specified the 15" Eminence driver as a drop-in substitute for the BZ series.I happen to use a single 15 " Au...

Folks,It is really amusing. Here I am busy myself for a while and am not looking and suddenly Roman talks about Mini Monitors and secondar phonostages.It is even funnier if you realise taht I am on a similar kick right now, simply because I am workin...

Thanks for your advice Romy and Stefano.I have used RTA with condenser mic in my past systems but I admit I am no professional at it. But I am not clueless with it either.. In my previous setup when I was playing with open baffle designed speakers, ...
|
|
Thanks, Jorge, but what you propose and what is done at the pictures your posted has nothing to do with Infinite baffle. This configuration rather reminds me the 4th order bandpass. It is popular setting but it is not what I like as the bass coming f...
|

I'm kind of wondering what is going on. The sound I'm getting now from Remedios is truly nothing special, it is very rich for a typical sound of 10" red driver. I might play with baffle, perhaps I will be able to get compression under control, even I...
|

[quote user="ayebee"]An observation that might only be of superficial interest to the thread: I don't think the speakers use Klangfilm woofers. The pictures are a bit grainy, but the dustcaps look far too big for the original Bionor woofers. I would ...

Guy, thanks. We are sitting now in backward, resting after heavy landscaping project. The project consisted of Amy picking up some weeds for 5 minutes and then I hit my leg with 35” wood spiting ox. After all she resuscitated me and we firmly concede...
