UK STOCK ITEM
The Monacor RBT-10 is a true ribbon tweeter featuring an 8x38mm diaphragm, a high power neodymium magnet and a 100mm circular alloy faceplate. The ribbon material is an ultra light (10mg) multilayer aluminium sandwich with a cross section of 0.015mm (approx 0.6 thou).
The end tensioning clamps form a substantial heatsink for the low impedance ribbon and an impedance matching transformer is built into the back of the housing.
We recommend a minimum crossover frequency of 3.5kHz / 18db octave.

Excellent customer service
Quick dispatch
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)!
