SPH-175HQ
Categories: 6-8 inch Bass / Midrange Speakers Monacor Drive Units
The Monacor SPH-175HQ is a 6.5 inch midwoofer with a distinctly classic feel about it. Features include a hand treated pulp / paper cone, a low loss rubber surround, a fully ventilated diecast chassis and a powerful 90mm ferrite magnet system.
This high quality loudspeaker is ideally suited to bass reflex designs. The damped pulp cone gives a smooth warm feel to the sound, the frequency response is extended and without major breakups. A very nice 'old school' style drive unit that will appeal to many listeners.

Very happy with this replacement part, especially once id fitted it correctly!! Sounds great so know where to go when the other one fails. 👍
Just as expected. Works perfectly as a subwoofer @400Hz in a mono bi-amped active internet radio set up in my study. Thanks!
Bought a pair of these to replace the failing drivers in my 20 year old Alesis M1 Active Mk2s. They are physically a near perfect match for the cabinets and are a good match electrically for the amplifier, but sound better than the original drivers. The only slight complication is the original drivers use one 2.8mm and one 4.8mm spade terminal, so you need to change one of the connectors. These have given my old monitors (now my 'kitchen speakers') a whole new lease of life. Next step is to replace the rubber surrounds with a grille.
There is a detailed review of these drivers over on youtube: https://www.youtube.com/watch?v=NCb-rzCSK2s
Great service from Willys. They were dispatched straight away and arrived next day, very well packed.
I recently installed the Linn Keilidh active Tweeter Upgrade Kits from Willys Hifi. It works great! It took
1 month to get here snd had to pay an additional 90 euros in taxes and customs fees but it was well worth it!
The foam grill covers of my Mission 770s crumbled into dust many years ago. Only recently was I able to find what I thought would be a suitable replacement. Everything about the process went smoothly. The foam cut easily, looks good and, to my ears , is audibly transparent.
