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 😉

well said luckly enuff im a qualified sound engineer so im a ok.still a bit of help from others dont go amissnnow an then..

Mr AHC would the driver baskets be steel or aluminium?

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, 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.

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

Impedance and connecting speakers (don’t bother with method 3)

A good spiel on crossovers

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)

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.

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.

: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

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.

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.
