using horn response and the measurements from our HD215's i've been able to simulate the HD15 using conical sections as an approximation of the exponential horn

first off the input screen :-

and the plot for the Eminence Kappa 15LF (95dB, 600W, 5.5mm Xmax)

i'll break the sims down by manufacturer over the following posts

Second that - good work! These will be next on my build list me thinks. Almost nothing but rave reviews from those that use them.

Anyone care to post about the plots vs. actual listeniing experience? (for their genre of music)

as you wish...

http://img20.imagevenue.com/img.php?loc=loc64&image=0ba_peavey_1505ka.jpg">

but you'd be better off with the 1505-8DT as it's got 4.8mm Xmax compared to 2.6mm (practically the same response for both so i couldn't be bothered posting another pic)

having said that the continous rating is only 350W for either of them so you're not going to get much out anyways

ps. more sims to follow i got side tracked...

it was originally done to match the plot rog put up with the design

1 bin in 1/4 space which is the same as 2 in half space (what we use above one X1)

unfortunately horn response won't allow multiple bins when the horn is sectioned like this but it would let you put 1 bin in 1/8 space to give you the plot of 4 in half space

there's nothing to stop anyone using the horn dimensions and doing it themselves or am i being too lazy?

Hi Dave

Could you please simulate the RCF L15P300 in the HD15. I have two speakers at home and I dont know would they be good for the HD15.

here the parameters

I don't have a response plot handy but I tried the L15P300 in a similar horn simulation and they looked pretty good.  I'd say they'd be fine in the HD15.

cheers dave, this is a great resource!
have you modelled the horn 'straight-up' or have you somehow compensated for the resonant component of the cabinet? i'd be very interested to know how if so - ive always felt an ordinary horn expansion model wont quite capture the magic of the bin. theyre just that bit louder than they reasonably should be innit? ;)

so what are people's opinions?
whats the new best bet when it comes to driving everyone's favourite short horn?
there's some 'unknowns' in amongst that lot that look very promising. interesting stuff

although it has to be said, one of the most important considerations for a bin with the impulse of an hd has to be the responsiveness of the driver, and this doesnt show up on the plot. some of those fanes look like they should sound great, but in practice they'll end up sounding all mushy


Posted By: Dave Slater
Date Posted: 17 November 2005 at 2:01pm

interesting points loophole maybe i should've put the EBP by each driver as well

anyways the simulation is based around the HD215 that Dom and i use

when i did the plan for that box i took the original measurements for the curve and drew 18mm flat panels over the top to approximate it

this created a series of conical expansions which i have then used the dimensions of to create this model

i've also allowed for the baton around the mouth

it'll never be identical but side by side i think it's close enough to use

i don't use a batten round the mouth, which is one reason i get a bit more sub than most people seem to with their hds. im also very into sneeky corner loading, stabbing other peoples drivers up with a screwdriver and other such dirty tricks :D

when you approximated the curve, did you plan the new panels so the edges where they meet are on the circumference of the curve, or so that the midpoints of the panels are on the circumference. or somewhere in between?
it makes quite a difference, because the first will decrease RC volume and widen the horn path, while the other will do the opposite. i should really start to build mitred boxes, its sooo much less effort.

ive always wondered what would happen if you made an hd with a conventional expansion instead of a radiused curve. could never tell whether it was laziness on rog's part to design it like that, or a genius trick that the rest of us dont know about - neither would surprise me :P

i wonder whether rog's plot also ignores the bandpass magic factor. maybe i'm biased but ive always loved hybrids, im sure theres something going on that hornresp can't account for...


Posted By: Dave Slater
Date Posted: 18 November 2005 at 5:54am

on the horn side the curve meets the panels at roughly the midpoints

i tried the other way but felt it didn't approximate it well enough

to be honest the difference is minimal we're talking a couple of mm at most which works out to the sim being about 10cm2 smaller in area at the endpoints of the panels

given the fact that horn response only allows 4 sections i doubt very much you'd be able to get it any better certainly you'd be hard pushed to notice the difference in the sim if you did in some way allow for those 10cm2

 



Posted By: norty303
Date Posted: 18 November 2005 at 8:15am

Even given that there may be funny room modes going on with my plots, i think the bandpass element adds quite a lot to the sound.  The sims show a peaky response with my measurements a lot flatter and lower before rolling off.  I did a number of different measurements with the mic at different positions before settling on the one i did but i can say that the rest were all fairly typical of what you see there.

I can also say that the first time i heard 8 of Dom's together it was whilst setting up a DnB night and they were certainly belting out the bottom end (whether i was really hearing the fundamental is cause for discussion tho..) so i'd say that his plots for multiple cabs also doesn't necessarily represent whats going on.

I'm running 6 next saturday (plus 2 double 18 subs) in the basement bar at the Stratford Rex (if anyone knows the room).  I'm expecting it to be fairly intense in that space, especially as the stack only goes under the roof with 20mm to spare.  Anything i should consider with reflections off the roof with the top end horns that close?

ok i have two drivers for you: the orion 15 inch sub in the H2 series, by orion audio, and the 15 inch madison executioner speaker.  those two have the highest xmax ive ever seen, very much worth simulating (ps i hate troubling people for this sorta thing, im curious what program you use so i coudl do it myself...)

Hi,
 
I have been looking around for Drivers for my next build  - 8 HD15s..
 
I have come accross the Celestion FTR15-4080FD and FTR15-4080HD for a good price and I was wondering if either of thease would be suitable for the HD15...
 
I have also had a go at working this out in HornResp but it baffled me..

Dave,
 
I've finally got to taking the back off my hd's and found that the drivers used are rcf L15L601's.

i've dug out the t+s for them and was wondering if you would be really kind and helpfull and stick them in the magic graph maker and model it for me....

i've had them running with PD loaded bins on a few occasions but never had enough time to do an a/b test.

I like em, would love to see what the theory says!

Right I might be getting four hd15 this weekend as a second rig.
Does that plot for the sn15b look doable? reason I ask is I can get these easily,
I would use some kind of sub, either an x1 or a reflex to do the 30<60hz [ish maybey a heigher crossover, whatever works]
for a small rig does it look like a good idea?
Thanks
Markk.

Hi there

Wondering if the Omega Pro 15 will work in this?

There have been many different sets of parameters but the design of the speaker has never changed (according to a gentleman at eminence). So it is safe to go by the latest listed parameters:
http://eminence.com/proaudio_speaker_detail.asp?web_detail_link=OMEGAPRO-15A&speaker_size=15&SUB_CAT_ID=1 - HERE

Could you plot this? I have four drivers so would plan to make four cabs.

OK.

Im assuming all the previous sims were based on 2x cabs on the floor hence 1PI, but raised above subs its 4PI?

HD15 is a "kick"-horn, so ya want the "boom" at ~120Hz, that's why it's a kick-horn! Wink

from what i remember of the 1550 sim was that it was only about 1-2db higher than pd154, and most of the debates i have seen about comparing the two drivers, most people said that in their opinion it wasn't worth roughly double the cost, 2 hd15's loaded with 154's coupled up would obviously be better but obviously twice as big and heavy, and you have the cost of building an extra cab.

I was having a conversation with someone just a few days ago about driver choice and high sensativity v's high power handling and xmax which is usually associated with lower sensativity, and also we discussed how now-days wattages are just going up and up to achieve the same end spl. He asked me again which drivers I thought were better, and I said in my opinion it often comes down to how big your van is and how big an audience you want to do, If you have a truck, use a larger number of bigger high sensativity cabs, if you only have a transit van (short wheel base) and need to do an audience of maby 1000 ish then go for a smaller number of cabinates with the new breed of drivers often handling about 1500w each cost after all modern amps are cheap, small and lightweight compared to carrying the extra cabs

Posted By: djwes99
Date Posted: 05 May 2011 at 7:48pm
Yes, actually it does seem to be the case that very suddenly the price of the 1550 has dropped a lot! maby due to the new 1551 coming out? :s going back a few months it was the general consensus of opinion that it wasn't worth the extra cash, but I guess now it can be easily enuff justified. I seem to remember the 1550 is a little bit lighter, which should make moving them a bit more pleasant too :D

Hello Dave and everybody, such a nice & usefull thread, but please help, it NEEDS UPDATING!

New neo NOW!
First: as you probably know the prices for neo's are going up NOW, several rcf drivers are 2/3 of the factory price from thomann, they didn't rise the price yet! I consider to buy Neos NOW!

mid-bassdrivers:
Driving a hd15 to 250 hz can be relevant for tms-2 and tse-111 alike cabinets (ev sh-1810, das st110 etc). DJ-leco asked for RCF MB15N401 sims, I would really like to see that sim Now!-)

rcf-info:
How can the the RCF_LF15N401 have a higher spl than pd.158 when the sensitivity is lower?

Missing graph
-As tweeter box pointed out in the year 2009 the pd.154 & pd.1550 sims are gone! -Are they censored? Or just missing by mistake?

THANK YOU SO MUCH PLEASE ANSWER :-)

rcf-info:
How can the the RCF_LF15N401 have a higher spl than pd.158 when the sensitivity is lower?
 
this can probably easily be explained by the quite considerably higher power handling (300w more) but probbaly more importantly the higher x-max, i think when i just looked them up the rcf is around 8mm and the pd only around 6mm, when it comes to producing high spl bass quite often high x-max is more important than sensativity, thou ultimatly it helps to have a high ish figure on both, sadly as x-max goes up sensativity usually goes down. Except of course with cheap rubbish speakers (eg, skytech, class D, soundlab etc) where both figures tend to be rubbish!

good point for max spl , but are these sims not all at the same 1 or 10 watts or something low?


Posted By: djwes99
Date Posted: 20 September 2011 at 9:23pm
ah yes, of course these sim's are probably based on 1w1m or similar. Well the other reasons will probably be things like..... The sensativity quoted by manufacturer is average sensativity, so even thou one driver may have a higher average, it may be at 1khz which for a hd15 is of no benefit at all..... other reasons may be the QTS and VAS figures, if these figures are higher then the driver might want a bigger box and as a result it may be slightly restricted in a small sealed cab like the hd15..... those are the main things i can think of at the moment :\

I think I've seen that 2226 sim around.

Edit: Just forgot I wanted to sim that for you, have the values on my other pc, I will sim it for you next time, otherwise just try, it looks complex but it's just about putting in the right values. If you have any chance, sell them & buy pd.154, here in Dk 2226 almost sell for the price of a new pd.154

I just simmed the drivers I mentioned above myself, and i come up with ONE BIG QUESTION:

Hov do hornresp respond to driver sensivity? I guess it does.
For me it seems like rcf mb15n401 / lf15n401 has the SAME sensivity in the horn!
But in the specs mb is 100db / LF is 97 db

Is that the bl factor getting lf up on the side of mb?
Any suggestions

I Tried to model the tms-2 horn myself from daves method, and I don't really understand about that extra path length, but the sim seems to work out pretty well.
The tms-2 horn is DIFFERENT! The back chamber is relatively smaller & front chamber bigger .

Just was thinking of using a couple of Celestion FTR15-4080F in an HD-215 but also have 3 single cabs that I need to think about loading shortly. Reason Im looking at these particular drivers is because I can get a very good price on them.
