I would like to talk about amp speakers. I am looking for something to replace the stock speaker in my Deluxe Hotrod. I have been considering some of the Eminence Patriot series as well as some Jenson speakers. I'm not sure what I want. I know that the stock speaker tends to buzz a bit when I crank my overdrive pedal and turn up the volume. These types of discussion are hard to do. Everything is subjective to the point of I'm not sure I could convey any of my thoughts, let alone understand those of anyone else. What type of speakers do you all like and what styles of music are you using them for? What keys do you mostly play out of? Do you use an open back or closed back? Let's rap, folks.

HB -
You are absolutely correct - this is as subjective a topic as any. My own feeling is that no answers will be right/wrong: it's all going to come down to you auditioning a variety of speakers until you find one you either love or can live with.
But first...
A super-fast Google of "Hot Rod Deluxe Speakers" reveals that different variations of that amp came with different type speakers - Jensen P12 Alnicos, Eminence Special Design, etc. Off the top of my head I'm thinking these aren't "cheap" speakers to begin with. They should be adequate to produce the sound the amp was designed for.
My questions for you are:
1 - Are you sure the speaker is buzzing? Or is the speaker not mounted tightly and is rattling against the baffleboard? For that matter, how about the chassis/tubes/transformers, etc? Sometimes we'll attribute a rattle or buzz to the speaker when it's something else entirely.
2 - What style music are you playing, and at what volume level? Are you going for high-gain at max volume? It may be that the Deluxe itself isn't well suited for such. The term "hot rod" can be misleading...

I normally play the blues, some fusion and jam stuff. It's the paper that seems to be buzzing. I don't normally turn the amp above 6-7 and rarely turn the drive above 3. Single notes are fine and I'm pretty sure no one else can hear it without being told it's there. I'm not sure what type of speaker mine has. It's a 2001 model. Just need to try some speakers. I suppose starting with a more expensive model would make since, I would be able to return it and not need to send any money other than shipping charges for the next one.

I've 'buzzed' a pile of speakers over time, but since I learned why I've yet to fry another.
The trick is NOT TO TURN THE POWER OFF immediately after thrashing them, but rather let them cool down. The adhesive in the coil windings melts when they are hot and will drip when shut off and still. Eventually these drips cross the gap between the magnet and coil and hence the dreaded BUZZ, which only gets worse because of the new source of friction.
Just give them a 'cool-down lap' and they'll last forever.

Did you like the original sound of your speaker? It sounds like the main issue is that the one you have could be busted! The label on the back will tell you what it is, and I'm sure Fender supply spares, though probably none too cheaply. If you are looking to change the sound in any particular direction, then there are certain suggestions that can be made, but there is a very wide range of models available- in fact I personally never really considered Eminence speakers because the range is so wide. After reading the first ten or so descriptions of 'smooth-warm-bold-full-whatever' I'm lost! The real problem here is that it is very hard to know a speaker without installing (and paying for) it, and comparing it directly with others to get some context, which most of us have little real chance to do, coupled with the fact that one mans 'creamy' could be anothers 'muddy'. I do know that Celestion have a reasonable sound comparision page... professional.celestion.com/guitar/features/tone/index.asp...which should get you started- other manufactures really should have something like that, not just to help customers to better select their products, but so that nuts like us can fine-tune our machines to the fullest! Other than that, I could tell you that I found my Celestion Vintage 10 to be Rich, Grainy, and Warm, the speaker in my old Deluxe Hotrod to be Full, Smooth, and Fluid, and the ones in my current Fender Frontman 212 to be Broad, Clear, and Sharp, but would that really help much? |

I'm not sure how to describe the buzz with the speaker. It's not busted at all, I suppose it could be the adhesive. It's more like the speaker is unable to handle the frequency range of my guitar with pedals in line. If I had a way to record it and post the file I would do so. Maybe I can work on that this weekend coming. Are there instructions for doing that in the forums?

Does that mean it only happens with your effects in line??
As for instructions on how to post sound clips, I would expect there to be some in the 'Sound Samples' topic- I had a quick look and couldn't see any, but the guys who have posted there must know how. It will involve finding a 'host site', as this forum can only link to material elsewhere, I can tell you that much.

It does occur when my overdrive pedal is inline but it's the normal buzz created by the pedal. It's the speaker. It's sounds like the paper inside. Though the paper isn't torn or loose. Like it's not able to handle what's being given to it. It happens when I'm jammin' at the house, amp no more than 2. I'll get it figured out, once I have the money. Maybe I could sell my body to some sort of scientific love Dr with brown hair and gorgeous personality.

Well, thanks for the kind offer, but I'm all stocked with bodies for the moment.  I was just wondering whether the problem occurs without any pedals at all- in case it is a problem with power to the pedal or a dodgy patch cable. Otherwise, as you are playing at low volume the speaker is not under undue strain. It could be all manner of things, as any component causing the buzz would still end up disrupting the sound from the speaker, so give the possible impression that the speaker was the issue. Can't really be much more help than that though, if no-one else here can help find the problem, a good amp tech might just be worth a quick visit, as he (or she) will be able to check the speaker and tell you what the problem is, or if it is indeed coming from somewhere else. Unless anyone here knows what to do with a muliti-meter to check a speaker??? |

I took my amp apart the other day and shielded the entire electronics compartment with copper tape. I haven't heard the buzz since. I have no idea what it was. It only happened when I was playing so I wouldn't think it was interference of any sort. Eh, who knows?

Hmmm, why do these always come in threes?  Are these the tone knobs? ;D ;D  Specificity, please. Do you mean just to check the resistance? This is all a normal multi-meter can do (unless one starts poking aboot with the probe tips).  www.eminence.com/www.eminence.com/pdf/tone_guide.pdf |

I have had good luck asking Ted at Weber Speakers for recemondations when getting a speaker. He is very helpfull in these things. I may be wrong, but I have never heard of a place taking a speaker back once you have bought it unless it was damaged when you got it. That is most likely why many of us have shelves full of speakers at home.!!

Sorry, I was being obtuse because I neither know what to check , nor how to do it...   |

Speaker coils have few Ohms and even fewer Henries.
Also, speakers are listed by impedance (which varies by frequency), not the DC resistance, which is less.
A resistance check will tell you if the coil is relativly OK as a piece of wire goes, but not much else.
