Hi Walt,
1,You say that the length of horns increase in cluster , hence their low
frequency responce will also go lower , how many punishers will we need
in a cluster so that they go down to 30hz ,
2, Can we use any other driver other than the caire in your design ,
3, How do you mount the driver , I could not understand from seeing your
plans ,
Thanks
Rajeev

I did find some drivers which give you a nice response in the Punisher, I didn't try them so don't know if they will actually fit in the cabinet. 18Sound 12LW1400 seems up to the job but is limited with regards to SPL max. The Ciare driver is almost unbeatable! Such a massive powerhandling (1000W RMS) and enormous lineair x-max.
The driver fits in from the sides of the Punisher cabinet.
Best regards,
Walt

2,Yes the driver can go in from the sides but how do you mount it with bolts ?

1,can they go down to 40hz in cluster, |
See pic; a measurement of one punisher vs 4 punishers. If your lucky you can get down to 50 Hz.

Bill,s autotuba has a similar path and that is 7ft also it goes down to 45hz single box ... that is if I understood rightly .
Walt had said autotubas path length increases in cluster then why not in the punisher ?

Are you thinking of designing another version of the punisher which will
be 40hz and also more driver friendly ?
Rory B ,
I think that problem is not there in the autotuba as the driver is only 100w
, also many have tested it and found it satisfactory .

Can your design be altered for a 12" driver as there is more choice in this size , you could increase the width upto 20" or so ?? Will you work on that ?

I designed a single 12"/double 8" horn for hifi use wich i think can be tuned for PA use. The hifi version geos down to 30 Hz (i have build the horn with double 8" configuration.
With some tweaking i think i can get more output and a botom around 40 Hz. The horn was originaly designed for the LAB12. It looks like the punisher, same folding.
And, i have been working on a double 10" 40 Hz horn for PA use. Here you can find the first drawing: http://groups.msn.com/_Secure/0SgD9Aj4Wkzwizp0amyMa!XUghqY9g O17UHA!qZbf5w2k1Ygmc192zzglm8PwFffZznGZEx9BHOCqJQOgvc*PCxirn GuixkezbNMOXMvpDEnIpJoEjys9PA/schets%2002.JPG?dc=46755098774 07877118
I only have a simulation of a single box on the net: http://groups.msn.com/_Secure/0UwA0A!kXdcJ1depvoeenaRB0qpJke P!oDwksNfMH4uo0fpz8NzzlcZWlX32YpHzbXe1rwhmljL29Y*xHaxRjjuAuH 1!5kCfnszH619V8MP17SewI4Ggy1va7tOyXzoMf/HLA%20BR%20vs%20HORN .JPG?dc=4675511920502531104
I designed this cab to use in a stack of 4. The dip won't be there if you use 4 cabs. the f3 of a stack of 4 is around 40 Hz. In the simulation the drivers can take up to 1000 watt each without reaching the xmax.
Max spl @ 1000 watt per driver (8000 total) in a stack of 4 is 144 dB @ one meter.
Dimensions are almost simular to the Mach Ballister, wich i think is a nice format.
Both designs are not the final designs, they need a bit of tuning before the preformance is optimal. If you are intrested i'm willing to work something out. You can contact me via email.

The design is ready for some testen in the field. To bad i don't have money the build a proto type and do some tests. If somebody want to invest in this project yopu can mail me for information. If not, i maybe build a proto type if i have some money to spend in the future.
And yes, it looks like the LAB. I wanted to use the same folding wich i think is the best compromise for this kind of sub.
Post by: raj on March 08, 2005, 10:16:38 PM
Yes your 2x10" looks like a younger brother of the Lab sub , It is a very good project for those who want 40hz and smaller size than the Lab sub .
Post by: michiel on March 09, 2005, 10:15:03 AM
The horn is tuned to play down to 30 hz with minimun space. And the horn plays wonderful in the subbass region, with an excelent sound! For hifi use a verry nice cab. I tested the cabinet before the building was finished. Now i only have to do the wireing a mount the last side panel.
For pa the doiuble 8/single 12 wont preform optimal. Untill now i didn't had the time to look at the modifications on this horn for pa preformance. I dont know when i have time to do this.

Now there are four promising Diy designs some are tested and some are in the verge of being tested ,
1, The first was Mike Nz,s ( michael elliston ) design with a JBL2226H driver ,
2, Second is Rory B,s design with a HL10 driver,
3, Third is Michiel Rijckaert,s design with 2x 10" drivers ,
4, Fourth is the Tuba 36 slim with a 12"or 15"driver by Bill Fitzmaurice ,
may be some more are on the way ??

If somebody thinks there is something missing let me know so i can up date the drawings.
Later i will post a simulation pic.

Attached: simulated respone for 1, 2 and 4 cabs. Spl is 1 watt at 1 meter. Max spl is 2000 watt per box at one meter (no powercompression).
Note that stacking will increase the effective horn length, i did not simulate this effect; the horn length for one box is simular to the length for the 4 boxes in this simulation.
The excursion at 2000 watt per box will reach the xmax at 40 Hz, above 40 Hz the excursion will be smaller. So the 1200 watt is easy to handle for the mechanic part of the construction.
The max powerhandling depends on the thermical powerhandeling.

I went through your plans or the 2x10" 40hz horn designed by you , You have done a very professional job and given the minutest details , even the size of battons etc , the responce curves are also very good , You have made an ideal design for those who want a smaller version of the Lab subs , I am sure your design will become very popular soon .
With best wishes ,

ps what is the length of this horn ?
Post by: michiel on March 25, 2005, 01:53:22 AM
Lengthe is 246-250 cm. The length will increase if the horns are stacked wich will give you a little more low end. I didn't simulated this effect because i dont know what the effective length in a sstack will be.
I discovered some small mistakes in the construction plans (on the second sheet). So here are the new plans.
