changing the crossovers and tweaters in cheap speakers worth it?

[Ext User(commodoress@gmail.com)]

i brought some cheap pure acoustics speakers (5 speaker pack) off ebay
about 6 months ago (dont start, i know they are cheap and crap), and
have problems with the tweaters in the floorstandings cracking when
playing music from my xbox (the center does it, but nowhere near as
loud). dvds etc all seem ok, its just playing music that seems to be
the problem at moderate volumes (not loud by anyones standards). amp is
an onkyo. i also tried playing music from a dvd player and its the
same.

i think it either looks like crap crossovers or crappy tweaters. after
some playing around trying to biwire the floorstandings and pulling the
connectors apart i noticed that the second banana connectors on each
speaker isnt even connected at all except for some plastic. so i pulled
the bridging pin out between the two connections and it actually made a
bit of a difference for some reason. i dont mind the look/design of the
speakers so would it be worth grabbing some new tweaters and crossovers
and changing them? or just throw the things out and get some new
speakers?

No,it's not worth it.

**Or a crappy amp, or a crappy source, or you're just turning the volume up
too far.

**"Grabbing some new tweeters and crossovers" is all very well, but to
actually do the job will cost you a bundle. It's kinda like me attempting to
put a V12 engine in my Commodore. It can be done, but I sure don't have the
ability, or money to do so.

Not really. You can get a cheap pair of tweeters and a crossover from
jaycar for not much money. Screwing in new tweeters and soldering in a new
crossover isn't exactly rocket science. Of course the speakers will still
probably sound like crap and it is probably throwing good money after bad,
but you never know.

**Indeed, you can.

**It certainly need not be.

**You have a better chance of winning Lotto, than improving the sound of a
pair of speakers, with no knowledge, no test equipment and some Jaycar
crossovers. In fact, I have a better chance of fitting a V12 engine into my
Commodore. Here's what you need (at a minimum) to fit unknown crossovers
and/or tweeters to an existing box:

* Detailed knowledge of the characteristics of the replacement tweeters and
the old parts. This will include:
Efficiency
Impedance CURVE.
Suitable crossover points.
Frequency response CURVE.
* A reasonable range of calibrated test equipment.
* The knowledge to use all of the above.

Not so,, I build a lot of speakers, and modify the crossovers to suit,
While a bench full of instruments will give you all the technical data
required , it does not translate that the technical specifics will insure
your going to get that perfect sound or output that you want, No amount of
metering will ever replace the human ear.

But to get back to our friend with the original post,, consider the
quality of your cabinets before you spend money replacing components. If the
cabinets are not up to scratch, regardless of what you install in them will
sound like crap.

Don't bother, you get what you pay for and having good components is just the 1st step, speakers need to be carefully designed. Buy something that sounds good to you, especially with music.

**You have arse about. No amount of human ears, can replace instruments. Not
ever.

Lets shorten the debate and just say,,,,
"Whatever I say" is incorrect, and whatever you say is correct.
There you go , happy now. even if you are wrong.
Pathetic, really.
No wonder you're completely unemployable.

**Nope. You're just flat out wrong, in this particular instance. If you
imagine that yuou are correct, then ask yourself why B&W, KEF, JBL, Legend,
Krix, VAF, Equinox, Orpheus and every other major speaker manufacturer on
this planet uses a variety of sophisticated instruments in order to aid the
design of their speakers. If it could be done by ear (alone), then don't you
imagine that these guys would dispense with all those instruments?

Would you care to explain how all these manufacturers have managed to get it
so wrong?

Come on guys,without the instruments you will never get it right. But in saying that what is "right" for one listener may sound like CRAP to another. EG.my nephew loves his ARRON speakers, I hate them. I think my brand sound better,but they are both professionally designed and tested with instruments . each to his own!

**And those differences can ALWAYS be quantified, via the use of appropriate
test equipment. Always.

**Indeed. Every manufacturer designs his/her speakers to their own
particular preference.
