UW 1058 Woofer
Categories: 10-15 inch Bass Speakers Morel Subwoofers
The Morel UW 1058 is a dedicated 10" high power, long throw bass speaker from the Ultimate Subwoofer range. This rugged drive unit features the Morel Uniflow™ Aluminium diecast chassis, a high flux double Ferrite magnet and a huge 5.1" / 130mm voice coil assembly wound with Hexatech Aluminium wire. The Accucenter™ self centering pulp fibre cone/cap is a one piece assembly offering high rigidity and excellent internal damping.
This drive unit features PFS™ Progression Field Symmetry: under extreme conditions, the spider and surround are engineered to act as progressive shock absorbers, preventing voice coil displacement and bottoming out - this improves voice coil linearity and maximum excursion.
The pole piece is vented (very large) for minimal compression under heavy drive conditions and power handling is very impressive at 500W nominal, 1500W short term peak. A full datasheet can be downloaded from the bottom of this page.

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)!
