Opinion on Crossover MODS??

Recommended Posts

Super Wammer

I have had my external crossovers re-housed to match my speakers and took a look at the components, see photos attached. 

Im feeling brave and thinking I may have a go at some DIY modding but don't want to tinker unnecessarily. 

Looking the components in the pictures, can anyone comment on possible basic mods or components that I could swap out that may give some level of upgrade?

thanks.

There doesn't seem to me anything you can improve. The air-cored inductors are of a decent size,the capacitors aren't non-polar electrolytics and the resistors are decently rated wirewounds. The resistors could be uprated, BUT, wirewound resistors have inductance, unless they're specially non-inductively wound, and that will have been taken into account in the crossover design, so I wouldn't change resistor type unless you're sure you get the same inductance.

As you have external crossovers, going active would be easy, and that's the way I would improve performance.

 As above Could be better I suppose but unlikely much .

 No idea what you have for gear but often amplifications make significant improvements. If ..determined to up your game.

  Amps like 'wimmin' are not all equal .

You have QLN Signature speakers on the end of Unison Research amp and you're looking to improve it :) love it. I had a pair of much lower level QLN which were amazing on the end of Primare amp. Can only guess how divine your system sounds.

I would second Serge's suggestion of going digitally active but that would require another amp as well as crossover. Crossover wise Minidsp 2x4 HD would be all you need and more.

I always thought that close coils should be avoided, and where possible they should be oriented in different directions.

I looked it up on't tinternet, and found this:

Thanks everyone for your input. 

Not being technically minded I was only looking to tinker with basic 'swap this for that' type upgrades, but it looks like these crossovers are not the place to start my DIY modding career! 😬

I will leave well alone. 

PS: My set up sounds great, I just like the idea of tinkering!!

What he said with the exception of using external crossovers ..  it allows you to to bi amp easily not go active easily - to go active would require an electronic crossover between pre and power amplifiers..

As to improving performance - biamping is subjective (I have yet to go wow when a system is biamped (where the single strereo amp previously used was high quality with good current production) ..going active well that is a whole new ball game :) (I liked the old ball game better)

"Leave well alone" - the best upgrade for many occasions imho 

good luck with your search for the next project !
