Ordered two of these tweeters on Friday afternoon NZ time, amazingly they had arrived in Auckland the following Tuesday morning, arrived in my home town of Christchurch couple of days later and were promptly installed. Seem to be doing and sound as they should, thank you for your service!
Thanks for the review Rowan, glad they arrived safely.
If that doesn't get the girls dancing nothing will !

The tweeters arrived promptly and packaged really well. For size and fitting they are a perfect replacement for the 55-06 units. As regard to SQ, at the moment they sound a little bright and forward; I’m hoping this will reduce a little as they run in. Maybe my ear is just used to the old OEM tweeters that were obviously quite a few db down after 20 years. Very much looking forward to hearing how they settle over the coming weeks. Thank you.
Thanks for the review Darren !

Great replacement for tweeters in Royd RR2 which had very dried out Ferrofluid and were down a fair few dB. Only minor easy mods required to cutout in speaker undertaken with a file. Well worth it, speakers sounding lovely.
Thankyou for your review !

Been looking for a supplier of replacement drivers for some years.
Willy's HiFi had just the parts at a good price and they arrived in a couple of days.
Excellent service. Even a personal thank you hand written on the invoice.
A quick delivery and the tweeters are perfect on my mission 753 freedom speakers. Easy to fit . Highly recommend.
I’m no expert when it comes to speakers, but after some research (and a strong recommendation from ChatGPT), I went with the SB Acoustics SB65WBAC25-4 as a reference full-range speaker in this size range.
Having now tested them, I can confidently say they’re probably the best speakers I’ve ever owned. The clarity is outstanding—every detail comes through with incredible precision. The bass is surprisingly full and punchy for a speaker this size, and they handle power impressively well. For anyone looking for a high-performance compact full-range driver, these are hard to beat.
Item as described and arrived quickly - and did the job. However, I suggested that anyone replacing speaker foam makes sure they have a very large pair of sharp dressmaking scissors as it was not easy cutting to size without producing a ragged edge (which I managed to hide short of a close inspection)!
