need speaker advice ?

[redbenjoe]

just got this ultra pretty sanyo mini --

the speakers are not broken --
but the bass is nowhere near as good as most all other of the better sanyo minis--
(or any GOOD mini)
they get flappy --fast
i even have to turn the bass control way down -- which suks

can anyone suggest a much better replacement --?
i think they are 3 1/2 "

thanks

Pretty hard since on those minis, depth is a big issue. Most "good" beefy speakers will be.... too "beefy".

Recommend try stiffening your orig cones by painting or coating them. That should help with them farting too soon. I have heard recommendations of using a thinned wood/elmers glue, and painting it on (they dry clear).

I might have to disagree with you there... 'tightening' up the driver is a good idea, but it will rob you of some of the low end frequencies that your looking for. The "flappy"ness that you speak of is the speaker's natural tendency to 'want' to rumble at that frequency. I.e., distortion, or a form of it. The amplifier apparently has the headroom to keep going, but the speaker simply doesn't.

My recommendation would be to find a pair of speakers that not only fit your radial circumference (I think you said they're 3 1/2 inches around), but also see if you can get a pair that will have a greater depth. I.e., if the originals are 2 inches deep, then see if you can cram a 3 inch speaker in there. Then also get something with a slightly higher wattage handling rate.

You will however be losing some of your mid range frequencies doing this trade! The other trade though will be MORE HEADROOM. Not having to turn the bass up, getting more volume without distortion... It's kind of a win-win, but only if the criteria can be met. I do a bunch of business with a place called Parts Express for handling small, long-throw speakers. They might have what you're looking for, but make sure you match your speaker impedance as close as you can before just purchasing any old set of speakers as well.

Hope that helps.

thanks --
space in these thin minis --for the deeper speakers is always a problem

Speaker wattage handling rate confuses me...........For example, I just recently acquired some speakers for a shelf system........The system is something like 15-18W per channel RMS........and 30W "peak/max music power"

So I get some speakers that say "30W max"...........And they are the correct impedence......

And yet they crap out at only 1/3 - 1/2 volume

In fact I've never found any speaker, on any boombox or shelf system, that is capable of handling everything the box is capable of delivering....

It also has to do with the THD rating of amp. This is the percentage of distortion. The higher the percentage the lower quality of sound produced continuously...Most Boomboxes have a high rate of distortion that when cranked up you can hear through speakers. Quality is key, and to save money most Boomboxes are built with lower quality parts...

u cannot cramp bigger speakers in these minis trust me i have seen a lot of these on the inside basicly the mainboard and all plastic parts that hold radio board and mainboard will not let u replace unless its exactly the same config,,yes this mini has some bass but remember how much more bass can u really squezze out of this box ,,i belive that what norm mentioned would be the practical way to atleast let the speakers handle a bit more of the bass plus keep it as original as it is now

 

[floyd]

will the jvc pc 100 speakers fit in there ?

 

[redbenjoe]

will find out -- thanks

And I can't disagree with LordRusell more. Tightening up the cones will allow it to handle MORE bass, not less but at the expense of highs, so me thinks LR has it backwards. Plus anyone that suggests to get the biggest baddest speakers to stuff in there clearly has never seen the insides of a mini boombox, which was the whole point of the orig question.

 

[hemiguy2006]

Ira,
I have a 2 step solution!!!!
1) Take that little mini and use it as a tire chock or door stop or something.
2) Use that golf cart of yours to carry around a bigger box like the Conion C100F or the Sharp GF1000!!!
Problem solved

i want my mini to blow away your wimpy 931

That's not exactly where I was going gentlemen... You all seem to think I was following an adolescent norm. My professional experience has lead me to to 2 trains of thought...

When we had open air speakers (usually subs) that were used in high humidity situations, they would always succumb to the 'flappy' sound our original forum poster spoke of. Shooting the cones full of spray starch 'was' one of our fixes, but the extra rigidity to the cone DEFINITELY had an effect on the sound & performance; not necessarily for the good. Could we get more headroom out of the cabinets? Fine. You guys are right. We did, at a cost of sound quality & blown speakers. [Yes I know, we're not talking about the same sound pressure levels]

My other train of thought was the throw or travel of the speaker. I.e., the travel of the voice coil. A speaker with that design would also be slightly more efficient, thus using less power & thus make better use of the mini's already stressed amplifier... Plus I'm not talking about doubling the wattage of the speaker either. Nobody said that. That's high school thinking at best. Common sense would only allow for about 5 watts at most above the rated usage. Otherwise you're wasting money & risking parts.

These ideas were to let the radio to continue to operate without physically 'modding' anything & hoping for the best. Like the 'starch' idea I mentioned, inking or painting the speakers is permanent & if it seeps through to the voice coil you'll be changing out the speakers anyway.

So yeah, I've seen much more than inside just a radio.

I think what you guys mean is, stiffening a cone with paint might improve its ability to withstand more power, and this it could co louder, but it might not be able to go "as low" anymore. Thus its frequency range has been reduced. So if before, the woofer could produce sound from 40 Hz to 1khz, now after being painted it can only produce sound from 50 Hz to 1khz...... (but it can go louder now).

Aptly stated. Kinda what I was wanting to say, but stumbled all over it... wanted to help... wanted to be the hero... get a little more 'oomph' for his box without butchering it. Started a debate/debacle.

Go figure.

 

[redbenjoe]

no worries lordrussell

lots of these minis are so beautiful --but some could use a bit of tweeking
to make them fun to hear --
instead --lots of these are just shelf-queen lookers

 

[Jboogie2384]

Hey RBJ I have some mini speakers sitting around. Two sets from a JVC Kaboom with and with out chrome caps. Various other ones as well. Let me know what might work. What the depth is. If the corners are flat or that other wingish looking style. Hit me up.

 

[TW5]

May not be a speaker problem
might be the amps
or filter cap in the power supply
check it with external speakers
or head phones

And clean switches and controls too

 

[redbenjoe]

thanks boogie
thanks TW5

will do --very soon
