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)!
Great service as always quick delivery
Thanks
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!
Excellent service well packed and very happy with tweeter after the work had been done.
Definitely would use again
