its one from "complete suites" they were going out of business so i snagged a nice bed, that dresser and two night stands. i replaced all the hardware though as the original knobs were black and it was all too black for me

most big cities have a "complete suites" store

Unfortunately, you're probably right, but... I'm still a little lazy, don't have any friends (with tools that is) and time is a bit of a luxury so I just dropped of a cut list to a lumber yard 5 mins from my house. They "promised" it would not be a problem keeping dimensions as tight as 1/16th of an inch. They asked $30 for labor so I think it is worth a shot. The order should be ready for pick up mid next week. Can't wait...

Oh, and according to UPS my Anarchys are out for delivery

I'd love to, except I'm not done with my home system. I'm thinking of trying a 10" or 12" single tapped horn next. If it sounds good, build 2-4 of them. Then, move to the garage

Thanks Vincent,

Outer dimensions are 48" x 21 3/8" x 7". I will try to add a cut list tomorrow or Tuesday in case someone is interested.

Btw, my Anarchys arrived a week after I ordered them, well packaged and in good condition. Not bad since DIY Cable is on the west coast and I am on the east coast.

Better be wider than 7" on the outside, or the drivers wont fit in there.

OK, at least large enough to fit the drivers then, or is the width an integral part of the formula as well? With the cost of the drivers being so low here, I gather that two drivers in series inside (then @ 8Ohm) also means that two such dual driver boxes in parallel (then @ 4 Ohm again) would be able to handle a lot more power, increasing the spl even further?

One other question I have is this:
If I am mainly interested in reaching 30Hz and do not really care that much for optimizing the parameters for reaching 25Hz, could a TH be designed for a higher spl, or at least avoiding any x-max problems, and maybe even get something like a 30-120Hz instead of a 25-100Hz? I am not requesting any revised designs here, just wondering...

- I am interested, since I have access to materials and equipment this week for building the original Insubnias, so I only need the dimensions and it need not be a fancy document for starters. If you give me the main dimensions (lengths) I can quickly render a 3D Sketchup drawing for you.
- Yup, things can travel fast these days, my best case was ordering a LCD touch screen overlay in Hong Kong on a Friday that arrived on the following Thursday! - and worked too

Correct you are LilMike

Correct dimensions should be 48" x 21 3/8" x 8". It had been a looong day.

We are currently finishing our basement and are putting in a gym, bar and a family room/home theater.

We have had a contractor helping us with a lot of stuff, framing, drywall, plumbing, electrical and some trim work but unfortunately he needs to be micro-managed and he also seems to think he is done. He doesn't respond to my emails or voicemails in a timely fashion, shows up only every other week to work for one hour and so. I decided that it is time to finish it my self so we get to enjoy. In the last few weeks I have spent many more hours in the basement than I was planning on. But Hey, at least I can justify buying a lot of new cool tools

On a positive note, building a HT (or at least putting in a PJ with surround sound) is how I found AVS Forum in the first place. I dabbled a bit with speaker builds when I was younger (a lot younger, over half a lifetime ago...) so I am somewhat comfortable in that area but you will probably see me asking noob questions in other threads when I get to controlling all equipment including lights using hopefully only one remote.

If you have the speakers in hand what is the overall diameter? From the spec sheet it looks like allowing 7 inches inside is a little tight. I know LilMike's design is 7 1/4 inch.

That's a pretty big ooooops Looks like I might have some grinding in my future... Actually, I will probably just route a shallow pocket in the sides of the cabinet to accommodate for the driver overhang. I think my mistake is still small enough that I should be ok.

Thanks for the heads up BIG. At least now I now not to be pi**ed when the drivers don't fit right

This weekend I cut a lot of plexi shelves for our bar and I have been telling myself, measure twice, cut once.... Can't belive I made such a rookie mistake...

Unless the wood's cut already, I'd just cut the interior parts wider.

A quick run through an excel sheet will get you the new values to toss into HR to see if it works OK.

Thanks LilMike, I have left the lumber yard a voicemail to make the internal pieces 7 1/4" wide. Hornresp gives me an 0.2-0.3 dB increase at 26Hz and 75Hz, 40Hz is virtually unchanged. I doubt I will ever notice.

Either way, it's pretty embarrassing...

From what I understand, they should be getting cut this week if all goes well.

First and foremost, thanks for "putting this together". I asked in the other thread about a flat pack Lab12. I've PM'd the designer but haven't heard back. Will you eventually work on a design for a 20Hz TH?

Great! What's the basic total cost including driver, shipped? Is shipping a flat rate?

Thanks.

I think Lilmike is working on some things. But they will be many times bigger than the 6.5" Anarchy.

For 20Hz, I would think so.

Staying tuned!

I know this might be a little late, but I just checked DIYcable, and they are working on prototyping some new sizes for the Anarchy line.

This could lead to some really interesting design opportunities.

(I'm just thinking out loud here...)

3AM,

I actually asked Kevin at DIY Cable about the 8" drivers a couple of weeks ago and his response was that "the timeline for the new drivers is probably going to be somtime this summer".

Bummer since I was itching to build something right now. But... maybe I need a new project this summer

Erich (and lilmike), if you want to cut the Lab-12 TH, it's a go. Here's a copy and paste of Don's reply to me when I asked him about having you guys flat pack his design. It even has his contact info.

Hi cecaa850,

All my designs are public domain. If you want DXF or DWG files, just email me at:
dsnyder1@san.rr.com and request the one you want.

It would certainly save some R&D time on a 20Hz TH.

Looking at that frequency response, which is similar to the Insubnia response, just a tad higher spl... looking especially at the +10/12db ripples at 100, 200 Hz... how much effort will I have to apply to get rid of them? Will a "normal" plate amp like a Dayton 100W crossed in at 80Hz be good enough to avoid them?

Did you ever measure the TB in this TH? I saw the modeled comparison, was looking for the measured comparison. I happen to already own 4 of the TB drivers and was wondering if it made sense to upgrade.

This measurement is certainly adequate to verify the performance of the design. We are essentially flat (+/- 3 dB) from 25 Hz to 100 Hz. 2.83 V yields about 86 dB at 1M, which is very close to the prediction.

Drive voltage from amplifier was set at 2.83V into an 8-ohm resistor with my most accurate voltmeter. My equipment is probably accurate to a dB, and should be flat within the area I have presented. Measurements were made with REW using the equipment I have described elsewhere.

I also did a little experiment with HolmImpulse.

Measured SPL and THD:



2nd Harmonic:



3rd Harmonic:



Hmmm, it is a 25 Hz tapped horn design and the THD takes over below that, pretty much as I expected, and exactly as theory predicts. I did not bother with the higher harmonics - they were buried in the noise.
Not sure how to interpret the bottom charts with the green lines. What do each of the two lines represent? There's no legend/key.
Do you have any frequency response measurements in a quiet areas? Apparently the first chart was with ambient noise at 50 dB. Am I missing something? Thanks

The lower line (for most of the graph) is distortion.
