Well I was making a routine dustbin drop and discover in the dark dumped outside on top of a trailer a what a appeared to be two loudspeakers, I noticed with the brief light from the alleyway one of the bass mid drivers was damaged, but still was better than treasure hunting in fact it was like Ētreasure huntingĒ finders keepers!

Itís an AWIA mini system so what Iíll do is check it over and see if I cam make a minor repair to the one of the bass mid drivers, luckily the edge rubber surround is intact so I might just be able to bend the plastic cone back into shape and seal the slit with some silicon rubber.


I must say this neighbourhood is strange just about anyone will throw out anything today. I only hope the next person dumps some JBL loudspeakers out side intact! :rotfl::D

So basically Iím taking in stray Hi-Fi systems now and if I keep this up I wonít have room to swing a cat around!:rotfl:

Well Iím starting off with a minor repair to one of the mid bass drivers. Noted inside itís a first order crossover. Driver is 5.5Ω wattage is unknown? But it canít be anything more than 60 or 80 watts?

LOL well it plays, Iíve got the RCA phones connected to the twin stereo outputs and Madonna playing it! :D

Its got a slight jitter if you tap the unit but hay Iím not complaining when someone damps partly an entire midi Hi-Fi out to be taken away by the dustmen first thing in the morning or worse the rain getting at it.

Iíll see if the tuner works later tape deck and amplifier as well, as Iím not starting to run out of plug sockets!:D

Note: it also has an optical digital output has well. Howís that for being born under an unlucky star! :rotfl:

Whoops I think I just heard it skip on track 3 Madonna Immaculate Collection yes its it got few problems to look into.

Well Iíve plugged it into a spare EQ and set the EQ levels from 160Hz 400Hz 1Khz 2.5Hz 6.3 16Khz to -12db and left 62Hz at 0db. Also set the input on the spear tape mode input to -6db so now it sounds like a non-sync CD player kinder like selecting the cinemaís Dolby CP-65 non-sync mode at UCI or the Dolby CP-500 at Warner village cinemas.


I think itís my CD disc that is skipping on this rather sensitive CD has it only does it on a few tracks and it doesnít do it on the Pioneer DV-525 or the other DVD players.

Also on of my one of my EQ has a dry joint on the PCB on one of the RCA phone outputs so Iíll solder that up later in the day. I mean its playing ok now but if I should move the RCA or joggle it around it would produce a hum! Hence its got a dry joint that I noted a few months back, but I didnít have a soldering iron handy at the time, so now is the perfect opportunity to fix that small problem.

Note: this the EQ that I have passed the RCA phone outputs from the AIWA CD midi deck upto, and then passed it outputs to the tape line input, and now I can set the fader at near 0db at the moment its at -8db on the fader. Also it sounds smooth and soft if I was to by-pass the EQ and set the internal input to 0db it would be blaring!

Also it sucks when the CD is playing loud! Before playing a film it sets the wrong tone and atmosphere film soundtracks rule OK!:p

Ok - you have hit a new low ... posting your fixes to AIWA gear with superglue & window caulking - :(
I mean, its a nice find for you - but this isn't even close to "Lansing Related Gear" for gosh sakes ... its just some cheap kit from the trash.

Really Ashley - there are other places for this kind of thing ...
You should start your own Blog for that ...

Try livejournal - http://www.livejournal.com/
They host your pages and everything -
the basic package is free, and even the fancy deluxe package isn't very much!

LOL, Sorry Heather, I couldnít resist:D. Well I doubt I might keep it might sale it in the free adds newspaper for a quick sale, or give it to a friend for free, hay do you what it!:D

Well looks like these AIWA SX-N7 three-way with first order passive crossover, stood up to the Apollo 13 dts THX laserdisc without breaking up! There bass response varied differently over the JBL Control 5.


So how did the damaged AIWA SX-N7 handle after my quick fix it solution with superglue and silicon rubber! Did it hold up to chapter 12 yes it did and it produced a nice tympani when the camera pans over towards the mighty Saturn V and tilts upwards there a nice boom located in this direction that peaked at 87dbC in the 62Hz region.

That was good enough for me and I was satisfied I managed to fix the bass mid driver with a bit sweat and practice and nimble fingers. It would be rather hard to find a new driver for it from the manufacture, or replacing each enclosure with newer bass mid drivers that would fit in easily.


Test tones sine wave A&B test was conducted as well.

JBL Control 5
32Hz 60.05dbC
62Hz 79dbC
125Hz 88dbC

32Hz 56dbC
62Hz 79dbC
125Hz 73dbC

So there it is the JBL Control 5 win with a lower frequency response:applaud:, it would have sound better if I could place the active crossover DCX2496 on the AWIA NX-S7, but that would be too nice.

Ah, there's more to it than Daleks ...
Anyway, I'm not gonna pay .99 p for a pdf magazine article .. also, don't need the You Tube for Confidential - I watch Doctor Who Confidential (uncut) on BBC 3 (hiDef) right after I watch Doctor Who each week - they've done a couple features on Murray Gold and his influences and styles - nice to get the music with the info ...
I also enjoyed the 2006 Christmas Cardiff Concert - broadcast from Cardiff last year with the BBC National Orchestra and Chorus of Wales - quite a fine "band". There's nothing quite like hearing a full orchestra kicking up the Doctor Who theme ... real nice!

I am always happy to read stories of audio gear saved and resurrected. Good show, JBL 4645!

For years I used my mom's old JVC mini rack system as a back up amp. Everyone seemed to like the dancing lights and it didn't sound half bad either.

You other guys... is it really appropriate to be needlessly critical of other LH contributors? Grow up!

Ether I was so hyperactive that night because once I started on fixing the broken bass mid driver knowing for well it would very hard to find a new bass mid driver and seeing it was a plastic type cone, I thought it though very quickly and said to myself out loud. Superglue and some silicone rubber will fix that.:applaud:

id say bully for you.............the snobbery shouldnt turn you away from rescueing a perfectly good back up system from the trash or "bin".it can be used, sold,traded,donated,and at the very least it is not occupying space in a land fill.i dont know why you get grief for that.the system in my office that i use when i read this nonsense is a 50 buck goodwill find.........i think i see why there are a lot of familiar avatars over to audiokarma.............

Just got back form shopping and talking to my next door Chicken Land neighbours, while walking down the alleyway I noticed what appeared to be two Abounded loudspeakers, and get this there AWIA! LOL! Model no ďSX-77Ē what is it with this strange neighbourhood abounding loudspeakers? I have yet to test these out and now Iím started to get cluttered with AWIA I rather it be JBL.:D

Just did a quick sound check to see if there working, okay no fault, except the bass was very poorly reproduced. I unattached the mid to high range that is used via the control 1, and set the crossover to off and tested each quickly because my evening is already turned upside down with this sodden virus, but if neighbours keep throwing out loudspeakers like an unwanted gift, Iíll tender it thou Iíd sooner find a newer home for them.:)

Just popped out again to show you where it keeps getting dumped, I live downwards and to the left, so you can see when I walk down the alleyway Iím seeing from time to time items cardboard boxes clothes and bits and odd pieces of AWIA dumped.:confused:

It looks like its going to rain tonight as the temperature as changed slightly from bitter cold to mild cold and its very cloudy. So if any of you like to pop on over for quick scavenge please do.

Remember those Aiwa I found dumped and saved from the weather a few years back!

Well it seems there are a few neighbours who donít mind tossing out speakers, like these Panasonic SB-PM15 bi-amp speakers.

Iíve tested them out with No Way Out that is presently playing in Dolby stereo tonight. They work! I was thinking they where done in.

The woofer is 5 Ĺ tweeter 2 Ĺ

The speakers have edge foam surround that is intact!

If anyone wants them NOT! LOL no if you what them Iíll post them to you otherwise Iíd find some use for them.

There was an amplifier outside but it was too dark and it would look dodgy if I used the LED light on the camera too see what it was. I could make out a basic EQ and tuner built in. It looked really cheap plus it was covered in condensation! So it wouldnít be wise to power it up as it would take days to dry off at room temperature.

Thereís also a CRT TV widescreen outside itís been there for just over a week! Iíd imagine its dripping with enough condensation to make it go BANG! :D

There nice little boxy compact size a bit bigger than the Control 1 there, make good surround speakers.

No I’m not replacing the Control 1 just kidding.
