Not convinced by the tuning winISD and bass box pro give differnt port lengths with the same input data.
 
Im going to build a prototype in the next 2 weeks.
 
Any input welcome

They should give roughly the same answers, working I should think on the same lumped parameter model.

Besides, you should be manually tuning the ports as well. Wink

Could you post both your BB and winisd inputs? I use BB myself.

Im a bit vexed on which to try first for the port length.

Ive read that people find bass box pro more reliable
 
whats the best way to go about manually tuning?
 
cheers

When I take a big interest in a project, I make my ports a little longer, then spend a while with some tools for cutting it down and using an impedance measurement jig to determine tuning.

The graphs are almost identical, or is it my quite bad eyesight? Maybe look at end correction?

the graphs are almost identical.
 
Im going to start with the bass box pro length.
 
what do you mean by end correction?
 


Posted By: Deadbeat
Date Posted: 22 October 2008 at 8:24pm
Bassbox Pro and winisd both have a port end correction coefficient which they modify port length by internally - this is usually denoted as 'K' and is why Bassbox asks you whether it has one or two flush lengths. Due to the massive change in acoustical resistance from the inside of the port to the outside, the port appears longer than it is. Think of it as the air in the port still thinking it's in the port as it exits. The exact coefficient changes with position of the port as well - you may find corner ports to act a little longer than they should.

If you search on here, I've done some pretty long posts on this - my hands are a bit tired atm sorry.

I did wonder how winISD dealt with that.
 
thats cool, ive been reading some of them already becouse im wanting to use corner ports.
 
Im gona put a plan us in a bit, a friend of mine has smart im going to try and get him to help me with it when it built for the final tweeks and crossover.
 
Thank you for your help Deadbeat its really appreachiated

Use WinISD Alpha, the later version.  You can select the amount of end correction it uses for the port position.  It also has more graphs available etc.

For corner mounted ports you will get quite a lot of effective length increase so start a bit shorter than the simulations, you can always glue an extra bit on the back if the tuning is too high.  In WinISD select both ends flanged or flush mounted as this will be closer to reality.

I did try iy but the drive is not in the data base.
When I manually add the data it tells me its all wrony.
 
I try downloading it again.
 
If the port get much longer I'll have to have a re-think

Made the prototype on sunday.

Not had a chance to to give it a proper test. 
I used a bi-amp crossed over at 1.6Khz borrowing a beyma FD-250 today off a friend and then Ill give a bit more testing (In a band situation)

It sounds good a little honkey in the lower mid range 100-550Kh ish but there is not padding it the top is amazing.

Will post pics later today

put speakons on the end with the top hat?


Posted By: djtecthreat
Date Posted: 11 November 2008 at 8:59pm
I'd put the speakons in the top of the cab above the horn with a recessed dish.  You won't ever have it upside down, but you may have it on it's back, sides, or bottom, as well as pole mounted.

or put 2 recessed pairs on both of the rear angled panels. and just link the connectors inside, so they all work


Posted By: eltron
Date Posted: 12 November 2008 at 8:41am
One on the bottom and one on the top, recessed, near the rear corner. That way you get a nice chain when linking cabs together on wedgework, and when on a speaker stand you can run the cable neatly straight down, no plugs sticking out.

Ive got this smaarted yesterday.
It been phase alined and time alined and is nearly flat from 200Hz to 2K smaart comfirmed the f3 is 63Hz

Its needed a bit of a bass boost at 80Hz but really impressed with the BMS drives.

Compared it with a martin F12 its better gain with out feedback, better bass (my enclosure is really small in comparison) and the f12 sounds like the vocals are coming from the horn only.

Ill put the plans and the DSP setting up some if anyone needs a loud compact 12+1 wedge and ill put some finished pix up soon

cheers

Have you tried some baffle step compensation, 6db or 3db per octave starting from around 300Hz?


Posted By: dlyxover
Date Posted: 03 January 2009 at 3:03pm
no ive just had a quick read and its over my head.

On the frequency response on smaart didn't deviate more that -/+3dB.

I trying to sort a passive crossover for it now and trying to reduce the dsp setting i.e manually time alining the drivers in the box.

Baffle step isn't really needed on a floor monitor as much...the stage is there as a 'baffle' of a sort.

Been using it with a band this week.

Its low end response is solid but not loud, could this be to do with the tuning or just he way the driver proforms? 

Snare drums in and vocals in recorded material sound fantastic, the snare slaps you and the vocals are really present.

A singer asked to turn the vocals down in it.

Im well chuffed thanks to all for your input on this project, its appreciated

I got my replacement DCX and did the smaart graphs.

I lost all the crossover setting and we had to start all over again.  Not as happy with it this time there is a big dip in the phase and frequency response at 250Hz. Going to try again when we get the time

My friend and I are still getting to grips with all of this and do not claim to be a expert so any constructive criticism is welcome






I will put some finished pix up when I find my camera

Gareth please tell me that you do put grills on when you use these? The thought of those luverly drivers getting kicked or beer spilt on them sends shivers!!!
Nice work on the cabs.
What amps have you got powering them?

Tony


Posted By: dlyxover
Date Posted: 27 January 2009 at 6:54pm
I fully intend on putting grills on them gonna get the off markie when i have some cash.

Im just using them in the studio at the moment, their quite safe
Im powering it with 2 channels of a QSC RMX2450, the HF is attenuated 11db

Gareth, my 2 x 12N620's get driven off a 1600/channel amp and have no problem at all with that.
I regularly use them on stands with out subs and they do really well even with DI'ed bass and kick.
 
Your cab tuning seems to be just about perfect but have you measured the actual port frequency with a mic or using a resistance graph? I have always found actual results to vary from the theoretical by quite a margin.

Tony


Posted By: dlyxover
Date Posted: 28 January 2009 at 12:02pm
Im want to upgrade the my amps to ffa they look and sound soo.

Ive not measured the tuning, how would i go about that?

the first time i smarted it my friend said it had a F3 of 62Hzish.

Do you run your passive of active?

Bi-amped with a QSC PLX3602 on the 12N620's and a Crown XTi1000 on the 4552nd comps crossed at 1.2K.

The easiest way to measure the actual port tuning is just to stick a measurement mic at the port mouth and apply some Pinky noise and look at the results using True RTA or similar. The port tuning frequency will be obvious on the display.
I believe Rog. has recommended this technique in the past.

Gareth, That's fine with the 4538. As you are not really pushing the comp and you have it on  a horn with a low cut-off you could actually try it as low as 1.5K.

Tony


Posted By: dlyxover
Date Posted: 30 January 2009 at 4:02am
I was playing with smaart today a checking the port tuning of the cab.

I don't have an RTA mic (whats not the best start) so I used a rode NT5


Its suppose to say 63Hz but it was flicking between 68-77Hz

I placed the mic in the centre of the port level with the baffle
is that right?

Gareth, with my cabs I have gone with the BMS recommendation of 25l / driver with a port frequency of 63hz. presuming you have done the same your ports could do with lengthening to give you a slightly lower tuning.
Of coarse if you have less cab. volume then the tuning could well be right.

LOL by looking at your pictures it looks like you have just copied a JBL SRX 712............

Everything is the same: Speakcons, horn size, Neo 12", size etc etc but i guess nobody is buying the JBL SRX now due to the fact they cost over a £1000 each new !!
 
Start selling your little monitors you couold make a killing !!
 
Lovely build and a lovely cabinet Thumbs Up

Did you tune the second one lower or stick with the original ports? And get the Fekin grills on Cry

Tony

Ive given it and extra 8mm on the port.  I cant really hear the difference to be honest.

they really kick out when in a pair, im taking bass out of them on the graphic need bigger amps now.

Im gona get he grills sorted, they are just staying in the studio at the mo.

Ok matey very well done.

Just one more tip when you put the grills on add some foam to them as well. I know the BMS cones are waterproof but it would stop stains from beer etc and protect the comp driver from the same.

Markie will do you some pieces of foam to match the grills.

Im still running them with a rmx 2450 but it only gives 650ishwatt at 4ohm.

Gona try it with my q66 4ohm bridged on bass, it claims 1700watt and the qsc doing hi

should do the trick

Posted By: dlyxover
Date Posted: 10 December 2009 at 2:54pm
I got the BMS driver from Tonk Wilkes on this forum, top guy.

They are a 25L (nominal) enclosure tuned to 63Hz i think.

was using them at a show with passive crossovers (for the first time) as DJ monitors, on very bass heavy tracks i was getting a bit of port noise which i wasn't happy about, never had that problem when running them active.

Maybe need to maybe have a re-think. 

Ive used them loads with bands as monitors and on FOH duty never had any problems at all.

Still rocking away, I took them out when I was touring with a band for 3 weeks, used them for the lead singer/guitarist, he loved them.

No issues with the drivers at all there loud, clear when used in pairs very punchy low end.

I've the need for some more of these wedges and decided to rework the design. (yes, Mk6 for these that are intrested)

Same internal volume and tuning, switched to round ports, using 15mm for the cabinet and 18mm for the baffle.
The enclosure is a little taller and shallower than previous design, tended to tip easily if pushed at the top when used as a wedge.

Added a brace off centre to stiffen the enclosure.

Speakon dish on the back and one the base same as before, top hat and one handle on the top.

Foolishly misplaced the router jigs I previously made first job was to remake them. 




Baffles up next

Dose anyone else employ the triple threat filling technique?


Hopefully will get them sprayed over the weekend.
Going with Warnex, was looking at something like Raptor liner but think i'll save that test for a smaller project.

I will be making flight cases for these also, can go into a bit more detail on that if anyone is interested.

Now to wire the speakon dishes and base speakons, cut and install wadding.
The grills will be manufactured by a external company and require a .dxf file, so currently getting enraged by Fusion 360.

The flatpacks were Mk2.

I can make the MK6 as a flatpack if there is demand enough.

Thanks SamV, I think the sound really good but I'm kinda biased: and im a big fan of BMS drivers.

For a small enclosure the give a surprising amount of low end, snare drums pop nicely and vocals are present and warm.

but as with every enclosure they have their limits, you wouldn't have a pair on sticks or a dub step event LOL.
but a pair on sticks work well for a jazz trio or small pub gig.

The finish looks really professional.

What size nozzle and pressure did you use in the set up for the bottom and spatter coats?

I recently painted some cabs but struggled a little bit to get a consistent finish.

A pressure pot sprayer is need for a good splatter finish, due to how thick warnex is a HVLP will kinda of work but not.

my set up is a cheap 2l pressure pot and the gun it came with, it has a 1.6mm tip
I put a regulator on the gun, so you actually see what pressure you at.

Leave the guns air pressure fully open and use the regulator to adjust you air pressure.

I had the pressure tank at 45psi for all coats.
Gun pressure at 25-30psi for the first 2 coats
Fan about 2 turns out
Fluid 2-3 turns.
spraying about 20cm away from the surface; over laping 50-60% on each pass.
Hold the gun as square as you can, you need to get even coverage, if you find there are stripes or lines in the finish then the gun is not being held square and putting more material down on the side that is closer to the surface.

I give it 2 coats with the above settings, it will not go down flat but have a heavy orange peel appearance.

For the splatter coats
pressure take at 45psi
fan full
fluid full
gun pressure 5-10psi.

Give it 2-3 coats till the texture and appearance desired is acheived.

I pretty much follow the recommendation from warnex.

I use a 50l air compressor just about manages it, it dose run constantly tho and I do have to take a brake every so often to let catch up. 
 With the constant running it gets hot and oily/rusty/watery nastyness collects in the tank a filter is recommended to remove this. (it really effects the finish)
Also drain the compressor tank before and after you use the compressor.

Low pressure will effect the finish, as the pressure gets low the material can't be pushed to the gun leaving a thinner film and a patchy dry looking finish

The tip of the gun will get coverd in thick overspray, keep a clean wet sponge and buck of water near by and clean after every cab, helps keep consistency.

I don't claim to have the best method and am sure others on the forum with more experience would have some advise, I'm always keen to learn new methods.

Nice build and nice finish! I'm also planning on spraying the new cabs with Warnex (definately because polyurea stays so damn expensive).
I have a 120L compressor available (8 engines) and two 270L pressure vessels so that will do the job probably.

Thank you.
Yes you should be rocking with that set up.
Put some photos up when your done, would be good to see your work.

Excellent instructions there, thanks. I think my problem was I needed the extra regulator at the gun. I was using a cheapo unit too and it only had one regulator as it went into the tank. That's good to know.

progress as halted.

The cabs are all finished wired up just need loading, well 2 are loaded and along with some q15 subs they are my hifi in the studio for now. Really happy with how they sound.

I wanted a fancy grill as such I've been learning fusion 360.

hoping too get the grills sorted in the next few weeks, then on to flight cases.

They will be going on gig next month
