Does anyone own a pair of Sony SS-M7?

[Jonny English]

Hi, I'm doing a three way build and like the design of the sony's - they were built in the US in 1994 ish. If you do own a pair I'm after the measurements and angles to get the front baffle and recline design right. Many thanks

We did have quite the fan of the closed box 3-way Sony SS-M7 a while back:

Crossover Mods to Increase Bass Level?

He moved on to the later Sony SS-M7A:

Good cabinet construction:

For the technically minded, I think these were Vifa 8" and 5" polycones with a Vifa soft dome.

A good enough combo, IMO. The sloped baffle, aka time-alignment, is quite the rage these days. 🙂

Thanks for the pics

You can estimate measures and angles by tracing (fprawn labs) good quality pictures, if there are any. Outer frame edge of an 8" unit usually is about 220mm, and some guidance provide enclosure measures.

Excellent - thank you

Jonny,

I bought the demo pair of SS-M7s from the local dealer on closeout when they were discontinued. They were my only speakers for years, until I got the bug to start building speakers for the fun of it. They still sound good in my garage driven by a Luxman integrated, probably better than anything I build if I'm honest.

A sketch of the driver baffle is attached, dimensions in cm, NOT to scale. The baffle slopes back at 11 degrees as measured both by protractor and smartphone inclinometer. The sides slope 10 degrees (measured on the flat sides, not along the front edges).

If you need more measurements, just ask!

Bill

Finished speakers

Didn't quite get the dimensions right but I'm happy with the result - sound good too.

Looks like you built nice speakers what drivers did you use ? And crossover slopes etc cheers

Can you give us some details on the build? What components did you use?
