Hooray! Two more Bose 802`s

[Skins]

Had to share this with someone as the missus just doesnt seem interested!

Came across 2 empty Bose 802 cabs a while back and did nothing with them, they didnt cost anything.:cool:

They were empty, no drivers, no wiring, no crossovers, just dust....

So, thought what the heck - I`ll rebuild em. So after sourcing parts and installing new drivers that were spares Ive finally cracked it.

Ive managed to re-wire the whole cabs, soldered each and every connection, installed the internal crossover,renewed the inputs and finally got them tested this evening and have to say I`m well chuffed!

Total re-build was around £160, which is pretty good when you consider these sell for around £400 a pair,

The cost wasnt really the issue, I suppose its the satisfaction of doing a job yourself and it turning out positive and only taking around 4 hours to do (would have been quicker had "her indoors" keep interupting!:bang:

I`m a happy man, !:D

Well done....saved a bit then....:)

[Skins]

I`m always one for spotting a bargain!

Like I said, not worried about the costs, just got alot of satisfaction from re-building em.

Used them again for a conference this arvo and they sounded fab!

If anyone wants any help or advice, just give me a hollar!

Xover? What About The Light Bulb Or Have They Changed. Tonytiger

[Cj_The_Dj]

xover means cross over

[TONYTIGER]

xover means cross over

i know what it means but bose 802 never used to have a x over TONYTIGER

[Jiggles]

you can get new ones that have a proper Xover on them like this:

to wire the speakers up is simple ohms law

so for 8 x1 ohms in series = 8 ohms load for your amp

see OLD 1970s 1980s design:-

1+1+1+1+1+1+1+1=8ohms
+0-0----0-0----0-0---X-0-ve <<< actual speaker wiring
1 2 3 4 5 6 7 8

if one speaker or wire or joint here failed you would enjoy a silent night!! ( see x at no7)

NEW:-
for using 4 ohms drivers
fact
please note 4/8/16 ohm drivers are the industry standard and the old valve amp used to have a switch to set to this choice 4/8/16 ohms
on older and other models/ranges bose do & have used many 4 or 8 ohm drivers.


|+0--0-| |-0--X- |
+-| A |----| B |--- -ve
|+0--X-| | -0--0- |

A/ 4+4/4+4 = 4 ohms
B/ 4+4/4+4 = 4 ohms

A4+B4 =8 ohms

if one or more speakers, wires or connections failed here you would get through the evening hopefully nobody the wiser

these are example pictures above only

yup,what that man said!:)

I think the old lightbulb setup was is much older 802 cabs, I remember them from way back and the inside would "glow" if driven too hard......

Havnt seem them for yonks mind you........

God i must be getting old

God i must be getting old

Me too Tony, thought the bulb idea was genius.

I had some Bose 101's, had a single 802 transducer in them (bit like the JBL control 1's), these had the bulb in and I once used them as HF tops!!!!:eek:
A friend of mine wrecked his compression drivers by putting Bass through them.
I had the 101's as my Van sound system, whipped them out of the van & wired them up to his HF amp and away we went, they were really pushed but did the job............bet the bulbs were glowing that night! :D

Not knocking it but the thing I've noticed when DJing on Bose stuff is that it seems a bit delicate, it doesn't like being pushed too far, feels like walking on egg shells so to speak.
Nice sound when it's kept within it's capabilities though. :)

I know what you mean., though Ive been to many a venue & event where 802`s have been used and they sound awful.!!

why?

Because most of the time people just dont use the bose controller, or unmatched amps.

We have a wine bar in swindon, just had a refit at a cost of 100k. Bose 802`s & 402`s thoughout and it sounds terrible............Bars are fitted with new 101`s......

Had a ganders behind the DJ Console one night whilst a mate was DJ`ing and would you adam and eve it ---- NO bose controller..........

Ive had a word to the landlord and he agreed it sounded pants, "but so does all music nowadays"....:eek:
:bang:

what can ya do eh?!
