Two Way Crossover

[Ken Clark]

Inductor Type

I noted that the inductors mentioned are P-Core type.
Any drawbacks with these or could I use them for all the crossover inductors?

My general rule of thumb is;

Low dcr for bass circuits.
Which normally suggests a cored inductor unless you want to spend more money.

Air core for mid and tweeter circuits.

Thanks for that.
Looks like I should be able to get all the bibs & bobs from SpeakerBug and just pay one freight charge.

Welcome
Freight in Australia is something people overseas don't understand

Crossover problem solved

Just to say many thanks to all who contributed to my various posts.

I finally rebuilt my crossover using the exact Heybrook HB2 circuit from System 7, with all of the bits & pieces sourced from SpeakerBug.

The speakers are now smooth & seamless (to my ears) with the mid-range harshness, particularly in the vocals, eliminated.

Best regards

Ken

Thanks for the update Ken.

Glad you successfully rebuilt your crossovers.

Happy listening!

Awesome news. Glad it all worked out.
Any more photos of the speakers and crossovers ?

Crossover problem solved

I'm away at the moment but will take another photo of the enclosure and the revised crossover when I return.
The crossovers are bulkier than the original units & I haven't been able to find a spot for them in the enclosure, so I've decided to mount them externally then revise the internal wiring to bring both speaker leads out.

Photos attached.

There are actually three partitions. The one in the centre extends to the side wall but this is hidden by the stuffing material (which is long haired sheeps wool)

The bases are river red gum which I was fortunate to be able to source from a supplier in the Southern Highlands (where I live). It probably comes from either Victoria or South Australia
