15 " Base Cab re-fit

Hi folks

ive just bought a couple of cheap speaker base cabs at the moment they are fitted with eminance me15 -3008 8 ohm 300w ive got chance of a per of new Fane Sovereign PRO 15-5005 one of the eminance speakers has blown so i just wondered wich is the best bet,buy another me15 or are the Fane a lot better speaker?

also im going to run the speakers from the bi amp socket out of my yamaha f12 full range speakers wich are 8 ohm so can i run 8 ohm base speakers as well from the bi amp socket ? if not will will i have to do ?

many thanks Steve in sunny Almeri spain

Fane are much better speakers.

They are 500w RMS with an spl of 98db

40~4Khz frequency responce range.

The Eminance are an older version of the Kappa I believe.

They are 300wTMS with a 101db SPL

35~2.5K .

The Eminance are a little more efficiant and will sound louder within their power ranges,

Fane have a better frequency responce and higher wattage.

If you arent having equipment problems and you're blowing speakers, the wattage rating isnt

high enough for the application so I'd go with the higher wattage Fanes.

I'm not sure I understand your bi amp question.

You didnt mention what kind of power is pushing the speakers.

A bi amp output usually means its an a line level output that has a crossover built in and you need another power amp to drive the speakers.

If the Yamahas are powered speakers then you're OK. If not you need another power amp to connect them to the bi amp output.

Some amp manufacturers call things by wierd names though. I've seen bass amps with dual power amps and a crossover built in.

then they have outputs to drive two sets of speakers as well as line level outs to drive additional power amps.

Just cant be sure here because you're lacking inportant info in your post.

basikly on the speakon input panel on the passive f12 there is another speakon next to it saying biamp,the yamaha f12 passives are being driven by a 350w 8ohm powered mixer,basikly i thought i could go into the f12 then the crossover in the speaker would send the low freq bass signal out from the bi amp socket to a bass speaker, un amplified but i may have got confused on how the bi amp socket works ,please see f12 info link thanks Steve

thanks for the speaker info ,i will go for the Fane as i can get 2 new ones for abought 200$ in the uk.

You head provied a Left and Right mains, or a mains Monitor setup.

I'm familure with those kinds of heads.

The speakers do allow biamping where you can run the woofer separate from the horn.

This is used in applications where you use two power heads and a crossover.

You can run a mixer > crossover> two power heads> one head recieves the high frequency from the crossover, the second receives the bass frequencies.

(you can also use a three way crossover and run three heads for bass mids and highs)

Since your head is powered, this is not a setup that would work.

This kind of biam setup is where you have a mixing board, a snake, power heads back stage powering multiple bass bins and horns.

Most of these kinds of setups are in the thousands of watt ranges.

My PA setup can be run that way. I have three power amps in my rack, but when it comes right down to it,

a good passive crossover works fine unless you're hauling a buttload of cabs.

In your setup you could get another power amp to push the woofers and use the built in power amp to run the horns.

You got to be "real" carful doing this though. Horns rarely need much power and that "HAVE" to have to use a passive

high frequency crossover so you dont blow the horn diaphrams. You cannot push the horns directly from the head without a passover.

The bass frequencies will blow the horns.

The comparison is, Horns may only need 50w in comparison to the woofers needing 300w to have a balanced output.

You may be able to run the head so one channel pushed the woofers and the other pushes the horns, but If I were to guess,

you wont gain anything doing this with a powered mixer and you'll only wind up having a very woofey sounding rig.

Lastly, be sure your speaker impedance matches the head. I believe yours runs best at 4 ohms for maximum power.

This means running two 8 ohm speaker cabs per channel in parallel will give you your best sound.

If you connect the speakers in stereo and in parallel, and one set of cabs are louder than the other, you might want to run

the speakers so one channel runs the upper speakers and one the lower set. This will allow you to balance their output more evenly.

Plus if you get the Fanes, you're going to get much better mids happening. You can always get another set of horns if needed and

use a passive crossover and run them as well. Thats basically what I do now and its more than enough power for any place I'd play

I run an older pair of Yamahas with horns and 15" speakers. I also have two 18" bins and a pair of Cerwin Vega three way cabs.

will wipe it from the head without

ok WRGKMC thanks im going to read your responce a couple of times and get my head around your advice ,thanks Steve
