Excellent customer service
Quick dispatch
Good fitting niet look
I have just received and installed a pair of Monacor SPM-165/8 Midwoofers from Willy's HiFi.
The delivery came 24 hours from ordering the speakers online, the installation was super quick and easy, and they make a tired old pair of Mission 732's sound terrific!
This type of service, from a UK based company, gives me hope!
Thank you.
My 1st time using SB Acoustics drivers and I’m really happy with them. Very hi quality, looks to match and most importantly sound incredible!

I was concerned that they may not look like the original binding posts on my Rogers LS6 speakers but they are a perfect match. Quite solid. Shipping was quick and easy. I recommend the product and Willys Hifi.
