kokomo5 4ohms cab or 8ohm cab?

[Kokomo5]

Hi My gear is a digital eich 300 watt amp into a smali 300 watt speaker 10inch in a  cab (if amp played on Max I  hear the speaker make a

snapping sound . I play Jazz / Pop in  small duo ,trio using a double bass sextets and eletric bass ,

in a very loud community band ,two Barritones and many other instruments.My gear seems to put out one volume, ok in rehersal,

or with a PA my DB is a cheap chineese bass lamanate and does not push out enough gain for volume from the eich and 10 inch speaker cab,

I have played in the street using my eletric bass with the amp on  10 Max and unable to hear the eletric  bass, in the end I now have the Bass Drum player not to play so loud which kind of works a little better, but not much.

I am thinking of one last push and getting say 2 10 with a new amp say 500wattor 800watt ( 500 into 8olmcab Would it be better to have a 4 ohm or 8ohm?

 Would there be much diffrence? in volume/sound

thank you for taking the time to read this post

Hi - this sections are for technical issues with the site such as pages not updating or account issues - if you have a question about speaker cabinets, it would be best to ask it in the Amps & Cabs forum

No one can give a definitive answer without knowing what you have for an amp and cab. I can say that you've fallen into the watts trap. Watts don't determine how loud or low your rig will go, not with respect to the amp, not with respect to the speaker.

[pete.young]

If you have a low signal from your DB, you might find that a pre-amp will restore the level to something that the amp can usefully amplify.

[Phil Starr]

A snapping sound doesn't sound good, it may be the speaker coil hitting the back of the magnet assembly If you hear this you need to back off the gain/volume and maybe roll off the bass. If this is indeed what is happening then your speaker will break fairly soon.

 

Speaker watts and amplifier watts are measured differently and I doubt that many if any 10" speakers could 'handle' 300W at low frequencies without distorting or hammering the coil to destruction on the back plate of the magnet. More watts aren't an option with this speaker I suspect. Getting a second matching 10" speaker should give you nearly 6db extra sound and help a lot. With DB you may get feedback issues though.

 

Where is your speaker? if it is on the ground then it will be pointing at your knees or your calves and not your ears. Raising the speaker or tilting it to point at your ears with a stand will improve matters a lot. Turning the bass down a little and turning the midrange up will also help. Turning the bass down will decrease the excursion your speaker is failing to cope with and the midrange is what we need to hear any detail in the bass above the rest of the instruments. Pointing your cab at your ears and re=eq'ing will help you in the short term and give you time to think about next steps.

 

Good Luck

Yeah I had this some years back, happened when I set the gain too high on my GK MB500, backing it off from 8 to 7 sorted it.

If you mean that the amp is Class D then it is not in anyway "Digital."

I think an 8ohm 210 would be a good upgrade. If it's not enough you can add another.

 

There is the possibility your amp is being overdriven or the outdoor power supply is suspect.

 

Best to try out a 210 with your amp before buying.

See Phil's and Bill's advice above. That poor single 10 is being asked to do far too much if you're expecting it to produce any kind of volume in a "very loud" band playing outdoors. When you play outdoors, you have no room reflections or resonances to assist and you need to move air, especially if you have no PA support. A single 10 can only do so much.

 

If you're running the amp flat out, the snapping sound you are hearing is either the amp clipping or the speaker over-extending, possibly both. As Bill says, it isn't just to do with watts. Your Eich is quite capable and will run into 4 ohms. You need more speakers. Even a 2x10 may not be sufficient in the circumstances you describe. If you add an 8 ohm 2x10 to your existing 1x10, the Eich should drive them happily and it might do the job. The only way to find out is to try things and see what works.

And adding a HPF to say 60 Hz, as well as a comp could help. Then you can cut excess from the low end, and push the channel better with a comp. It is not any louder, but may feel fuller than it is.

Absolutely.

I am not quite sure, whether this is a feasible term here, but HPF could be described as a rumble filter. It is used in HiFi systems, especially with turntables. It cuts handling noises.

Thanks everyone for the advise, it has put me in the drivers seat for my future playing

Kind Regards,
