It looks like I'll have some new toys for a few days

I have a custom order for some really powerfull subs

Planar horn bass reflex?

18" on BR,decent anyway.


Posted By: Mircea Bartic
Date Posted: 12 March 2006 at 5:40am
it's a design derived from dynacord Planar wave horn subs

the port ending outside the waveguide helps achieve better subbass reproduction

horn coupling is not necesary

Ah yes i remember that sub now. When you do make some,could you measure its impedence vs frequency etc? Im interested in how that short tunnel helps it at all.

COOL horn expansion rate  - PV Low Rider (if meet spec) look like a drop-in substitute for US cheapass.  Are PV Low Rider 18 OK?  -- I've 1808 and they are way off specification so are now "open baffle woofer"

one way of testing if other speakers work in the design is this one:

because there is no speaker simulation program capable to polt this design we have to work around that.

1. plot this speaker in bass box as a simple bassreflex box (no horn)
2. load another driver in that enclosure and try to reach the same plot
3. when you have identical plots then it should work ok in the planar horn.

modifications to the reflex ports will be necesary

I know that P-audio c18-650EL works in this design , but you have to shorten the ports by 110 milimeters

does anyone know where i can get the full plan of the sub above? Those are really easy to make. Just move the baffle half way....

I have heard those (dynacords) in stacks of 6 per side during an outdoor concert in a square. Rattled my glass of wine in the bar i was in.

probably a silly question, but i'm assuming to load the driver you shimmy it
past the mouth brace and then climb half in side the cab to bolt it in?
pictures would indeed be nice, plots would be nicer.

2 questions:

Can you explain the hornloading part of this box?.. In other words: How do I do the math to design that horn?... Are we talking Helmholz resonators or ?

Why does the handles on your drawing say "Cobra PWH" :-)... Did you measure a PWH sub or are you just using the outside dimensions and retuning it to suit the Selenium driver?

1. the design is still using a Helmhols resonator, but beside that there is a waveguide in front of the speaker.

this subwoofer acts like a horn above 60Hz but below it's like any bassreflex design,
It's a bit weird, but it is not based on sims and serious design, for the simple reason that I have no programs that can simulate this thing.

Trial and error is the key word.

2. it says cobra pwh because I used the picture of the cab made by dynacord to draw that picture.

P.S.
Dynacord subs do not look like that on the inside
They use resonators inside the mouth of the waveguide, and that causes some problems, because in theyr design the sub sounds BAD at close range
By extending the resonators at the waveguide mouth we were able to corect some phase abnomalies thay ocured in the previous design, and make it sound much better at close range.
Dynacord's problem came from the fact that the resonators worked inside a horn that was not able to sustain the long wavelenght that they produced.

this design is smaller than dynacord's by about 30% and sounds better

Looks like that patent has expired, so no problems with making this type of speaker.

I was wondering what frequency have you made the front waveguide resonate at? The front waveguide looks a little short to me, so whilst the extra width pulls the resonant frequency down, doesn't it reduce the loading on the driver at the higher frequencies? 

Would a small triangular section in front of the speaker to act as a throat into a small section of horn load the speaker better?

They look rather attractive in that you can ( with a few modifications to the dimensions) make one out of a single sheet of ply (apart from the bracing and vents)

"Looks like that patent has expired, so no problems with making this type of speaker"

The Yamaha patent is still active, but may not be a problem unless you are going to build for retail sale.

This type of patent runs for 17 years from date of issue. Newer patents run 20 years from date of application (after being granted). This ends up being about the same length of time as it takes about 3 years after applicatin before they issue.

Paul Voigt used a 1/4 W stub with his designs back in the '30s, I doubt if a modern patent would stand up to litigation.

The design from Nexus_3 looks well thought out.

Very nice indeed.

Can you tell more of how do they sound.

I am trying to find the right home for my 12 18Sound 18W800.

Mybe this box will do.

 

Please give us some more coments and pictures.

How would a cluster of 6 or 8 sound?

I realise that time wise it hasn't expired however according to my checks they never paid the fees for the patent so it actualy expired some time ago!

Having looked at nexus's picture, I somehow think my woodworking skills arent in the same league - but thanks for the pics, it has given me some clues on how to go about it . I'm having ago at building some 18 BPH's this week, then I'll have a crack at one of these. Somehow I don't think I'll be posting pictures though.....

those are a version of the F17PWH from dynacord, but with mid drivers on them

the 2x15 version is not fully tested yet

I would encourage you to build this planar horn using the 18" driver

The plan is very similar to the Stage Accompany XL-Bin. Look at www.stageaccompany.com


Posted By: PoteirosCorp
Date Posted: 12 April 2006 at 6:53am

Do really your planar will need a mid-bass cab ?? or can be used to 150hz

I guess that version of F17PWH will have the mid drivers closed.

I'm thinking on your planar charged with LX60 from Beyma (specs are like the selenium) and on a non-distance future put them plateamps   and turn them to active systems (a friend build them at a good price). Of course modifications to the ports will be necesary. 

On the other side, how is your opernsource midtop going on?? 

Cheers

1. the planar horn goes happily past 150Hz just fine
2. you guessend right
3. interesting ideea of putting plate amps on the subs (I presume there will be some beefy amps inside)
4. opens source mid top is stagnating at the moment, but I'm sure that as the weather warms there will be more activity (warm weather means prototype building)

not good

if you'll use those mid tops you'll not be able to hear any mids  because of the huge amount of bass.

trust me.

you need something like this:

First of all the original 'planar wave horn' is nothing else than a 7th order bandpass, and that's how it sounds. It does NOT play well above 100Hz (which is why Dynacord demonstrated the Cobra4 system with PWHs from 35 to 60Hz and direct radiating 18" bassreflex boxes from 60 to 125Hz). By putting the rear chamber ports to the front you'll get a 6th order bandpass. Yes, the tunnel in front of the cone does NOT act as a horn, but as a box resonator (it's still helmholtz). You can simulate this by selecting a bandpass of 6th order and set the front port area to the area of the tunnel and the length for the port to about the length of the tunnel. Of course frequencies above the high roll off will come out of the box, because nothing is blocking them, so you measure a slight dropoff of around 2 or 3dB per octave above the calculated high rolloff, but the sound above 100Hz will be muddy.

If your smaller version does sound better this is for a simple reason: The smaller, shorter chamber pushes the high rolloff to a higher frequency. Again, this is in no way a horn....

The F12 top is very weak on mids, of course this can be resolved with a new crossover (which you will need to do anyway because you will use other speakers). It is very important to crossover from the 12" to the HF-driver at or below 800Hz (the original is crossed over at 800Hz), because this horn has no phaseplug and will start to roll off at 700Hz. The sensitivity of the 12" is around 103 to 104dB in the original, so not that much. The second top shown on the cz site is surely more efficient and better sounding in the lower mids.

Planar Wave horn and matching top

 

Hi all !

 

Last info about the original PWH-subs was they sound horrible, letīs hear if the outside-the-guide ending ports will do better.

Using AJ-Horn5 this construction should not be too hard to simulate. Give it a try.

I recon the JAN Audio-horns for the tops surely are excellent material. Your pic shows an MX12. Recently I try to make them sell a single mid-sized 12inch flare, that will be an M12.

Anybody got experience with the M10, M210 or the M212 ?

BASS IN YOUR FACE!
Very nice Nexus, how do they compare to the X1?
Sounds like this sub has all the benifits of a reflex and a horn design in one box!

I don;t know how it compares to the x1 because i never built one

the planar horn defenately sounds better and trows sound farther away in open air conditions than an X1

F#%kin' hell, again, THIS HAS NOTHING TO DO WITH A HORN! It's a bloody bandpass!

the guy from dynacord who desighed this thing thinks otherwise

He had read this thread, and has confirmed that this design DOES act like a horn

I hope he'll post here soon

i think he meant that the x1 is a bandpass

the planar is a horn hybrid, defo has horn quilitys [like hd15 has horn hybridisms within] the planar is a horn hybrid [a nice looking one too!]

how low? and whats the size?

I'm talking PWH. It IS a bandpass. A horn has ALWAYS an extending flare aka a flare rate above 1. That's the way it works. A non-extending flare aka tunnel is a resonator! In addition a working horn sounds COMPLETELY different. If you want to simulate, what the front resonator does to the sound coming from the cone you just have to use WinIDS, set it for 6th order BP and set the front port to the length of the tunnel in front of the speaker and the port area to the front area of the tunnel. Of course it will play higher than the frequecy the simulation will show, because the direct sound of the cone will go straight through the tunnel, but it won't sound that good. In fact Dynacord demonstrated the Cobra system on last years PL&S with PWH subs only used up to 60 or 70Hz, using direct radiating Cobra subs for upper bass and low mids!

BTW I know the head of developement from Dynacord. He supplied me with a full Cobra4 setup including 8 PWH subs about 1 1/2 years ago to test them. Cobra Tops great, Cobra PWH Sub simply put NOT, sorry. And that's what I told them. I think the people at Dynacord know now who I am and contact me directly, if they have problems with my statement.

Sup guys, First of all let me tell you. I've been reading all your posts and I just love this site.
I want to find a home for 8 EAW LC 1827 ( I dont hve any specs on them) On a forum someone told me that they ware RCF L18/300. Any way.. will these drivers work on the planer horn? Im planing to push them with 2 QSC USA 1300.
Thanks

A lot of EAW drivers are Eminence OEM but that's easy to tell if you can see the driver and especially the magnet.  If they are OEM versions of the RCF driver then they might be ok in the PWH.

Good Thinking on build one for test and then build more if im happy with it
 
Did you have the design on that dynacord speaker you talk about and witch components from P-audio are the best to use? 


Posted By: Mircea Bartic

my bad. my question wasn't that good I mean for the dynacord speaker. have you some design on the inside of it?

And how is the sound of the sub? can it be used to both hard dance music and also live concert's? 


Posted By: Ambrocio
Date Posted: 03 July 2006 at 1:47am
Hey come to know that my 6 EAW are Eminence Magnum Pro 18-LF, I built a pair of planer wave horn and I must say they really work nice. Im pushing them with a QSC USA1310 in mono at 4 ohms. Ill post some pice up tomorrow.

I would rather use something different for hard dance music (wih a bit more kick)

for live usage they are great dough

I had the plan for the Dynacord sub somewere here, but it's not verry diiferent

it has a large port venting inside  the waveguie

Dynacord is using the EVX 180 A driver (electrovoice)

Okey! Do you think I have to modify the length of the ports if I load them with omega pro 18?


Posted By: Mircea Bartic
Date Posted: 03 July 2006 at 3:35pm
absolutely no modifications

the Omega pro 18A acts exactly like the Selenium 18SW1P , the only drawback is the considerably smaller X-max

A highpass is absolutely necesarry @ 40Hz

a:- Fane 18xb600
b:- PD186
c:- PD184

Hi Nexus 3,
 
I like the look of your Planar Sub Bas Box.
 
Can I ask, do you know what it would sound like using a Void V-18 1000w or PD1850 800w driver in there ?
 
Cheers.

What are you waiting?

It would be interesting to see how they perform against a 2x18" 320L-40HZ, a 1x18" 150L-40HZ, and real horn enclosures like Punisher.

Actually i need something to go under my HD215 (30/35-80Hz) and i've not decided yet if go on 2x18" reflex or something horn loaded like WSXtra and Punisher or this hybrid.
Performance/price/weight/dimensions wise.

Outdoor/indoor events, live rock and techno use, max 700-800ppl.

Can you give us al list of recommended dirivers, in order, if you can Nexus

Can this subwoofer be modeled as a sixth-order bandpass with a front chamber volume of zero and a vent as large and long as the planar horn? I plan to test this theory, but if someone could just tell me that it can be done, it would save me a bit of time.

Just had a look at PD184 in the vented cab part of this design ( I ran it as a 130 litre vented cab, 400 sq cm vents 490mm long.. ) It looks like it will do the trick aswell... Xmax limit @ full power just below 30 Hz (-9 dB or something, but not really relevant as the horn should give some sort of boost aswell ?)..
 
Can anyone confirm that the PD184 will survive in this cab without retuning ?
