That's a big room you are talking about filling up. And I suspect the acoustics in a garage that large to be challenging at best. The vinyl isn't going to serve up the extreme high or low end response that digital or even tape would. So super reveling speakers aren't needed, and may be a waste. But they will display every pop and tick on the record.
I suggest you consider something like the very common $200 Kenwood KL777 series. I'm very happy with my KL777A for loud, clean, fast, rock, jazz, voice...….even acoustic piano. Affordable, 98 DB sensitive, good range, handles 100 watts and parts are available at good prices. You will need about 80 watts on occasion with the Kenwood. It's not one of the little darling speakers but has it uses. And this is it.
I don't think the little KLH, Advent, Ar...…... type bookshelf speakers will step up to the job on this one.
The big throaty Wharfedale and Bozak will if that smooth sound doesn't get lost in the bright room. This is not a job for the mighty Rectiliner 111 either. They need to much power but wont handle enough of it. Then boom goes that fine pricey mid driver.
