Need to replace a pair of emminence 15 inch speakers though i have no idea what emminence speakers i need to replace them with as theres no info on the back of em??? Help!

i just recently replaced the 15 inch cone in my jbl with an eminence.as far as i no im pretty sure they only do 1 power rating for the 15 inch (not 100% on this tho) the best place to buy eminence drivers that ive found is maplins..hope ive been some help.did you buy all of dans gear?couldnt have made it up there to pick up that tweaker box tho pretty gutted....talk soon..:bounce_fl :bounce_g: :bounce_fl :bounce_g: :bounce_fl :bounce_g:

nice 1 raj thats some help for me to as i need to get new drivers for the tops on my peaveys...:wink:

[Raj]

:smile: excellent - glad to help :)

If your replacing them do you not have the old driver to check?
What kinda speaker are you changing them for? Sub bass/kick bass/mid?

fuck knows there from them mids i bought off danooops on here. theres nowt on the back not even what wat they are or what Ohms and i'm shit at stuff like that.

You should be able to narrow it down using the spec sheets - they tell you what they weigh and all the details of how they look. They will at least allow you to narrow it down anyway. Every speaker driver weighs something different.

Dan may be able to recall what amp was powering them which would also help you out :wink:

probbly easeyr just to get rid of the cabs n buy new. it will put me behind scedule for spring partys otherwise.

[MrAHC]

looks like the delta-pro is the man for the job but it runs at 8 ohm. sure the others were at 4ohm??? fuckin confuses me so it does.........

[Raj]

The resistance will vary depending on how you link up your speakers - you can take 2 x 8 ohm speakers and connect them in parallel and get speaker resistance = 4 ohms

no i dont tw@ mate of mine left em in da cupboard when he moved out of his house real sharp along with 4 of my 15 inch drivers an the wood (cut up an ready to assemble!!) so a bit pissed off about that 1!!they are mid/top flared horns so will have to check dimensions befor buying....why did you ask??....lol...thought you was talkin to me???loosin it i swear!!

[elretardo87]

If you are buying new drivers CHECK THE THIELE SMALL PARAMETERS FIRST (http://en.wikipedia.org/wiki/Thiele/Small).

Compare the paramteres of the old driver with the new one and if they are very similar then it will work in the cab.Buying any old 15" driver will sound shite, especially as people tend to go for the most powerful driver they can afford.

Mr AHC if your stuck stick up a picture of the back of the driver and I'll see if I an help.

d.r.e.a.m if you tel us what type of cabinets you have I can suggest the ones that will be most appropriate if theat helps. As your wasting money on drivers if you have the wrong ones in as they are not designed for the job so they will sound shit or break, although probably both.

nice 1 would be well greatfull...they are peavey HP400....also some numpty blew my xover inside so if you could help on that 1 would be even more greatfull...they are propper bad boys double 15 inch bw's!!!been running them just as bass cabs with an electronic xover!!

do you not have a compressor?if not get 1 but make sure it has a delay of 3 secs or more as most are only about 1-2 secs..this i think is 1 esential bit of equipment as it will protect your amps and stop any dj's tryin to crank everthing up on the mixer..

[Raj]

Compressors are only as good as the person who sets them up is at doing so; badly set up they can cause a lot of damage as well as making your rig sound crap.

My advice is do not allow redlinemokeys to play if you can avoid doing so. Otherwise find an expert to set up the compressor for you if you are unsure exactly how it works :wink:

I'm afraid if you bought an eminence delta 15lfa its not really suited to your cabinet. It won't sound horrendous but you won't be getting the most out of it. You have essentially bought a drive unit designed for bass applications so with the 1" compression driver your gona be left with a serious dip between the hipass of about 2khz reccomended on the peavey compression driver and the steep drop in output above 1khz of the eminence driver.

Better off going with what was in the originally which would be a peavey black widow. We used to have a pair of HP400's (well when I say have I mean it in the loosest possible sense but I have dealt with them before a fair bit) anyway the best driver we could find was a peavey black widow. Phone peavey and ask which one I can't remember which one we used in the end as there were two that were suited since they updated the design. A rig needs to cover a full frequency range or it will sound pap....as bass ain't everything.

Mr AHC I can't read the model number and I can't sem to find any info on a 15" Eminence big cat so could you give me the model number? Although if they are a simple reflex cabinet, like ours (http://img.photobucket.com/albums/v324/elretardo/15012007093.jpg), I would reccomend fucking off the eminence and getting a pair of P-audio SN15mb as they are quite cheap and I prefer the sound tbh. Its what we use and they sound really nice.

[elretardo87]

Also a bit of prior research can save you a hell of a lot of cash so iheres a few thing I reccomend you read:

Thiele small parameters and matching drivers to cabinets (http://www.speakerplans.com/index.php?id=faq1)

Impedance and connecting speakers (don't bother with method 3) (http://www.teamrocs.com/technical/pages/connectingspeakers.htm)

A good spiel on crossovers (http://www.resolutionmag.com/pdfs/DRAGONS/CROSSO%7E1.PDF)

For the keanos....heres the Yamaha Sound Reinforcement Book which covers almost everything (its a bit too old to deal with some of the cuttin edge stuff though) (http://books.google.com/books?id=d7ft6F8ZUdcC&pg=RA1-PA58&lpg=RA1-PA58&dq=crossover+frequencies&source=web&ots=1gUK_sFc6n&sig=e8M64zQPQkiWHogVvE4iTEBLiGQ#PPP1,M1)

Thers a million and one different things to know and learn and the more you research the less times things will break and the easier it will become to deal with faults in the field.

Knowlegde is power.

[BioTech]

Elretardo is giving sound advice. It's very important that you do not stick any old driver in the cab just because it matches the power, size & impedance of the original driver.

Cabinets are built to suit the theile small parameters of drivers and vice versa (eg drivers are designed with the required parameters to match a cabinet).

It looks like there is a model number on there. What does it say?

Are they out of action? Your other option would be to get them reconed. Most recones are done with recone kits that match the driver but there are clever people out there that can fabricate cones along with voice coil etc to suit many drivers and then fit them. I can put you in touch with someone that can do this if you want.

[MrAHC]

this is what i'm saying theres no model number or any info at all....

[Dan Ooops!]

:laugh_at: Ok guys - without it being said, I seem to be taking a bit of stick for these....:crazy:

They were handbuilt by Ooops! in 1994, and those Eminence Big Cats were put in. I was never the technical guy in our crew, so I'm sorry if my opinions/beliefs are incorrect!!!:cry:

They were built as F/R cabs to sit on the bins Tek Offensive bought from me. The TS parameters were followed, as the guys I worked with were fairly confident in what they were doing.
:crazy_diz
The cabs also contain a 10" and a bullet tweeter, giving 3way passive F/R cab.

We eventually disconnected the tweeter and used them as mids in an actively Xovered 3way mono set up (using the EVs as tops). I always believed that they were 500W 8ohm cabs, using 300W 15" and 200W 10" drivers.

I did have a look for the plans, but as the missus made me hide all the old Ooops! paperwork when we got this last house, I cannpt lay my hands on them.

Sorry Mr AHC, and many thanks to all you proper pros for trying to help him out.

The cabs themselves are pretty well put together and even contain a correctly dimensioned internal box for the 10" driver. I wouldn't recommend chucking them, but if they really do not suit your application, then someone else would be happy to get started with em.

They should suit someone out there

Peace

Dan

[elretardo87]

this is what i'm saying theres no model number or any info at all....

Righty heres my other 2 pence then....

Eminence big cats are pretty retro so I can only find info on the 10" version. What I can find tells me there is little point in getting them reconed, they were pretty budget speakers back in the day so now they ain't all that.

If you can get me a picture and some details of the x-over I can suggest a suitable driver, though at the moment I'd definatelybe leaning towards a p-audio sn15mb for them. Its a fairly cheap driver that will sound good in a reflex design similar to yours, although I'm not sure on the port sizes or tunings it will definately sound better than a reconed big cat.

Chill man for £25 I would have had them if I lived near you. If the build has lasted 14years then they are not firewood material. Its just a bit of confusion.

[General Lighting]

I think the big cats may have actually come from Maplins as they opened a store in Reading around that time. I know the guys who would have selected them and they did know their stuff.

its worth remembering that in 1994 there wasn't anything like the spare cash and resources and info to hold parties that was about in the early 2000s, people made do with what they could get hold of easily. That said, OOOPS and the Reading crews which followed them were some of the most technically advanced for the time.

Although I had a bit of knowledge about rigs I never got involved much in speaker design as I was too busy with the logistics side like sorting out buildings or the community aspects, so unfortunately I know next to jack shit about speakers other that they are heavy, and it helps to point them in the right direction and round here you need hench straps and even battens behind them to stop them being moshed over :laugh_at:

I'm sure there must be a driver that could be substituted today.. If the bins are no good to AHC I expect one of the younger East Anglian or SE England crews could use them.

:laugh_at: Ok guys - without it being said, I seem to be taking a bit of stick for these....:crazy:




Dan
Your not gettin any stick mate I'm just tryin get em fixed asap. I'm useless with stuff like this and I've fired our tec man off coz hes dodgy :laugh_at:Theres no info to go on so thought I'd ask here..

[BioTech]

Yeah no worries Dan, I don't think anyone was insinuating that. Just seemed people were telling MrAHC to make sure the new drivers he bought would match the original ones you had put in.

[MrAHC]

recon i'm just gona stick a 15 inch, 350w, 8ohm eminence bass speaker in? what does everyone else recon? the p audio ones are to expencive realy.

from my (limited) knowledge of what went into system (trying to think back 14 years isn't that easy!) I would say it is not too far off what went in the cabs in the first place back in 1994..

A rig needs to cover a full frequency range or it will sound pap....as bass ain't everything

are the tops bw's 2?yea deffo no what your sayin as i have 3 12 inch which i use for mids an a tweater box on top so i cover the full frequency range quite easly.hense why i said they make good bass cabs at the mo because the rest is coverd (dont mean to sound rude but i do pretty much no what im doin just a litle advise here n there dont go amiss as you never no what yer gunna learn...) thanx any way i will get on peaveys case an see what they gota say as i personally think they are 1 shit hot pair of speakers...what about the xover will peavey be able to help with this to or do you no of a better source?

[MrAHC]

just rang 'davemanchester' as were workin on somethin and quized him and he goes with my theory that stickin a 350w bass in will do the job. The xovers look like they have been took out of the equasion so they can be run as mids.
There havin 15 inch 350w eminence delta bass in em.
Well its been a learning process :wink:

[elretardo87]

dont mean to sound rude but i do pretty much no what im doin just a litle advise here n there dont go amiss as you never no what yer gunna learn..

Sorry if I insulted you its just that the answers you gave AHC were a bit off, especially about how to choose a driver for a cabinet.

[Raj]

The proof of the cabs is in the hearing folks ;) - you need to be happy with how they sound. We all like something slightly different in our speakers :weee:

the ev tops i got off of dan will make up for any loss in mid or top end anyway. there wicked wee things so they are deffo worth the journey down

[Dan Ooops!]

All sorted then....350W bass drivers, and the 10" with the EVs on top. Banging!

And thanks guys, I wasn't feeling a proper kicking, and price was right for the stuff. We loved em when we built them - And I reckon over time Mr AHC will have a play, get to know them, and use them as best it suits his rig. Fucking solid boxes, well constructed - load em up and let me know where I can hear them!!

Good job soldier.

Its an oldschool design but a nice solid basis to build upon. Once you have a 20kW hornloaded beast you can use them full range as monitors.

not gona go much over 5kw it will limit us even more as where we can play

[cheeseweasel]

A rough but not all that reliable way of telling what the nominal impedance of the speaker is is to measure the resistance across the terminals with a multimeter, giving the impedance at DC, and adding a couple of dB to it. Its not accurate by any means but if all u need to know is whether its 4R or 8R then it should do the trick.

Never tried it personally so someone tell me if I'm talking bollocks, i'm just trying to remember looking at impedance plots for uni a couple of years ago but most of what I learned has fucked off out of my head so I could be wrong.

[MrAHC]

its all sorted now mate but ta for that.

[elretardo87]

not gona go much over 5kw it will limit us even more as where we can play

you say that now
