If you are driving the speaker too hard it will pop. This caused when the voice coil is driven mostly beyond the pole pieces of the magnet. Without the magnetic field the back EMF of the voice coil drops off and the current shoots up. The voice coil can't move farther so there is a discontinuity of movement which causes a pop.

200 watts is a lot to put into a 12 inch speaker so you have to be careful to not drive low frequencies at excessive volume. It is both very hard on the amp and doesn't do the speaker any good either.

If you want loud lows, you should get a subwoofer of at least 15 inch speaker to handle the lows.

As an owner of the same amp, it just can't go above a certain volume, and that volume is pretty low...I'm selling mine for that reason.

Hi i have recently purchased an rcf hc3200 and 4 x event 4000 speakers, these were all dommenstrated and shown to be working fine however when i connect 1 speaker to the amp (either channel) the sound...


Bass cancellation can occur if the polarity of one cable is reversed? Positive at the amp MUST go to the positive at the speakerS else one speaker will be pushing & the other pulling & the low frequencies get cancelled. You may also hear some strange imaging effects as you walk around the room - a bit like stereo from a mono setup.... check your cables :-)

Home Studio Recording: Part 3


Once again, we dive into the subject of recording your band's (or your solo) album. So far, we've covered the basics, and how to record drums. Today, we talk about the all-important Bass Guitar.

There are a few different ways that you can do this, one being the industry studio standard of using a Direct In box, or DI. How this works is you run through this box, which then has two cables. One to the mixer, and one to your amp. You then mic the amp (see below for mic placement), and get both the clean and amped signals together on the track, giving you a fuller sound.

Method number 2 - Amp your bass, and add the effects there at the amp. Compression, chorus, and distortion are some popular ones with the bass guitar these days, even in country music. Light overdrive gives a bass more high end sparkle, making it easier to hear it at the lower volumes.

Method number 3, and suggested if you don't have a DI box as well as if you don't want to anger your neighbors, who bang on the ceiling with a broom (just joking on that. Still, don't tick them off!) - Plug your bass straight into the computer, and record two tracks simultaneously. On one of the tracks, apply an amp simulator with the desired effects. On the other, apply ONLY an equalizer and compressor, in that order. What this does is gives you the amp tone, as well as accentuates the lower frequencies of the bass guitar. It's the shortcut that actually produces great results.

For mic placement on your amp, you can use either a condenser mic (which requires a preamp, or a mixer with phantom power), or a dynamic mic. Both will give you a great sound, but it's up to you to find what fits your sound, and your budget.
Placing the mic. - Pick your best sounding speaker. To do this, turn your amp down, and play a note. Go to it, and listen to each speaker by placing your ear directly in front of it (this is why we said turn it down). If your best one is close to the floor, rotate the cab so that it's one of the top speakers. Using a standard mic stand, place the mic so that it's pointed directly at the speaker, but it's about 2 inches in front of the cone, and 2 inches to the side. You can experiment with different placements, such as directly in front, or to the side and pointed across the speaker, but this is usually the best sound you'll get.

That's all for this segment of Home Studio Recording. Join us later for part 4.

Takamine eg523sc... the bass string (6th) is about 30% less in volume as the other strings what could i do to correct this problem?


You should take this to a guitar shop for setup. If you have correct strings on there the other thing is to check any EQ of whatever you run this into... If the amp can't handle the real low bass, it MAY appear to be a guitar problem but in fact is an inadequate frequency response at the low end in the amp and speaker.

ALSO some people believe it or not get deaf in the low range if they have damaged their ears when young. Procure a sound meter to VERIFY the sound intensity level... You may find the level is the same for the different strings.

The weak spot for bass is the SPEAKER in the amp.

When we are trying to get a reasonable level of sound for vocals before it gets loud enough to be able to hear clearly with the band playing it starts to clip at the speakers now we are only using this set...


Proper level setting of the mixer is important. HOWEVER if the clipping is occuring at the speakers the only possible problem MIGHT be that you have a supersonic feedback that is saturating the speakers above your hearing range, Be sure you don't boost the highs too much with the EQ as this can cause the feedback that you can't hear. Also make sure that you power the speakers from the SAME receptacle as the mixer, even if it means running an extension cord to bring power to the mixer. This is to avoid a low frequency hum and common mode distortion/damage. A low frequency hum could cause the clipping.
It would be a good idea to get a sound meter to check the sound level. You should be able to reach 85 Db from this system without clipping. If you need more than that, you MAY need more speakers if the band instruments are too loud. Also if the band has amps that get into the vocal microphones that adds to the clipping level... make sure the mics don't "hear" the band instruments. Make sure your speakers are toward the audience from the mics to avoid the supersonic feedback problem. If the vocalists can't hear themselves with that configuration you need to set up seperate stage monitors.

There are some pretty good videos on YouTube about proper mixer level setup.

I have a 92 Gibson T Bird with ebony fretboard, and a new one with rosewood fretboard. my old TBird doesn't have the brilliance in the highs as the new one does... i changed all the pots yesterday, with...


The most I can suggest for getting the shine back to the bass is to run an EQ before your preamp. Make sure all sliders are set to zero, then raise the higher frequencies until you get the sound you're looking for. This won't lose any growl, just accentuate the brilliance.

The best EQ to use would be a BOSS Bass Equalizer. You can use the same on your old T-Bird to accentuate the lower frequencies, and get almost the same sound.


Hope that helps!

I have Ibanez gsr200 bass guitar , yesterday and today I noticed that my bass's voice is irregular , please help me how to solve it , It's a new bass , Thanks


No question what to do... take it in under warranty since it is new !!!

You may find that there is a problem with your amp... the seller should be able to test the guitar and demonstrate normal sound for you.

Many users have TOO small of an amp and the distortions make it appear that the guitar is bad... I suspect you will want at least a 12 inch speaker and preferably a 15 inch for your bass.

When low frequency signals drive a speaker too hard it drives the voicecoil out of the linear range and the sound will be irregular..

Amp volume drop with flabby bass sound.


1) can happen if the speaker is dying - voice coil defective or magnet needs recharging. happens sometimes with low quality speakers. 
2) faulty pre-amp section can reduce overall gain resulting in lower output volume.
3) for old amps dry solders in pre-amp & power amp section can have the same effect.
4) faulty coupling and filter capacitors can severely effect frequency response too.

I think I blew out the woofer...low frequency rumbling...is that something that can be easily switched out?


The woofer would only blow if it was overloaded with too much signal. The common cause of this connecting a speaker of lower power than the amp or ohms than it. The simple way to cut out rumble is at the amp by reducing the bass, however most amps will cut all the bass and not what you want. Another way is a filter designed to cutt bass or low sounds. However your best bet is to use a Graphic Equalizer to control the tone, most have a 31khz control which will cutt the rumble you describe, but keep the wanted bass sound.

If you strike a low note too loud you risk damaging the speaker itself. The low note will cause hte speaker to extrude too far when loud and can either pop out completely or wear through the voice coil and short out the amp.

In short, don't do it.
