DSL tweaking!!!!!
glen - 2013-03-02 21:16
Hello everyone . QUESTION: Does anyone know whether there is a way to tweak the DSL circuitry on an AWIA CS 880 to produce a more deeper Bass. when i opened up my AIWA i did see a few adjusters by the Amp, wasn't to sure what those switches boost,if theres anybody out there that knows, give me the low down pleeeeeeeeeese...
Btw the reason why i'm asking is because when i switch on the DSL at low/high volume it comes on but u hardly notice it, so i'm thinking maybe the DSL volume can be tweaked.
Thanks... Glen

Hi Glen,
I would suggest you to study the circuit diagram first for this model. Try tracing the circuit that leads to the DSL control, if there is a pot to adjust the gain then you should by means tweak and see if there is any respond to the low frequency. If not maybe you can take the challenge to change the Rx C value to enhance the low pass frequency. Just a penny for your thoughts!

Yeah, i think i did see a couple of pots to adjust, but then i may just upgrade the woofers for more powerful ones. Just gotta find 5.25" ones with a port hole through the magnet, max wattage say around 70w

I suggest you get her recapped....these have superb sound if there working normally

capacitors that need replacing,i have an aiwa 600 and the caps have started to go on
that..its fine when you turn it on but after an hour the caps give in
radio.raheem - 2013-03-03 12:22
Sorry my bad glen....capping is when you get the capacitors etc replaced.....these degrade after time and the sound deteriorates..... those main speakers in the 880 are better than those found in most boomboxes.....i can recommend members such as retrodos recapping is not recommended to be done by members like me and you son

Have you ever held a speaker in your Hand whilst it is playing sound's?
Ever Notice that the Sound emanates from both the front of the RAW Speaker and also out of the rear or backside where the magnet and basket structure is?
Read - http://en.wikipedia.org/wiki/Loudspeaker
You dont Need a Hole through the magnet to the inside of the box for the passive radiator to move.
Any Speaker meeting the Ohm and Efficiency rating for this size of box given and the frenquency you wish this to respond to, if we are being critical, or just get a speaker that fit's and works and play it by ear...
There can be many reason's for the Hole through magnet in the rear of the speaker in this design of boombox, I offer just One: That hole is back there to relieve the pressure of the compression of air trapped under the dustcover when the woofer is in it's rearward stroke to allow the dustcover to remain in place and not be ripped off of the cone during long excursion's of the woofer cone traveling in and out re-producing sound. designer's gotta have their 'chrome' dustcaps bling...

To recap a boombox and get restored sound....you need to replace them all....
not just 2

Most people in the boombox collecting and preserving area Prefer to keep the
looks of the Box As Orginal as they can therefore keeping ( Most of them Chrome
dust caps ) in front of the orginal woofer's -
First you should really try to get
the original speakers re-foamed and or also reconed if needed preserving the
orginal cone & voice coil to best show off the bleeding orginal dust cap - just
for show!
Now if you are after the absolute best sound that you can get from your Aiwa
CS-880 you may replace the woofers with aftermarket speaker's that probally wont
have the chrome dust cover ( you can find the chrome dust cover's online and glue
them on) after you find the perfect sounding woofer that sounds best to you...
You dont have much of a choice over there in the UK.
May I reccomend that you consider a car speaker as they are trying to give you
the most sound from a limited amplifier source in a vehicle enviorment versus the
links you suggested that are mostly designed for home speaker replacement -
Here are what i found just now in the UK that you may wish to try:

The Pioneers are excellent Full range speakers just one problem the ohms i need is 8ohms and not 4. I read that if u have the wrong size ohms it could damage your amp.
(1) If you connect your amplifier to the wrong speaker impedance, you risk damaging the amp. In tube amps, too high a load impedance (or a disconnected load) can result in damage to the output tubes or output transformer, while in solid state amps, if the speaker impedance is too low, the amplifier will tend to overheat and more power is used up in the amplifier than is delivered to the speaker. Too many speakers on a solid state amp can burn up the power output section.
(2) The amplifier will deliver maximum power (volume) to the speaker when the speaker impedance matches (is equal to) the internal impedance (called the OUTPUT IMPEDANCE) of the amplifier. Too low an impedance will result in weak output and poor tone. If the speaker impedance is higher than that of the amplifier, its power output will again be less than it is capable of.
So i think ill go for the Sound lab speakers. just gotta find a couple of chrome voice coil dust caps to stick over the ones already there.

Where did you get your information for number # 1 as Part of it is written incorrectly, or needs correction.
Eight Ohm's is what came painted? on the back of the woofer for the CS-880 I should have confirmed that First. Didn't. I stand corrected
Your Selection of woofer has a Too Low of a sensitivity (84db)
Should look for the Highest efficinecy db rating in the smallest vas for your application

I dont have the vocal cords to shout that far
For a backing material of the radiator this has: HI-Tech !! Cardboard
instead of foam rubber like your's does
For another project that got finished another way for a customer a very Long time ago...
this is not the correct size or is it?
Pyramid Phase III tenna One pair Model PR8 8 inch passive radiator
