AR9LS Speakers - a good buy at $1k

Acoustic Research was a top of the line speaker. The company folded many years ago. The AR9 is a 40 year old speaker. IMO, you should save that $1K and buy a newer speaker. Here is the information on the AR9!

What kind of amp are you using? This new JBL Stage A-180 and A-170 is under a grand. I’ve never listened to a Bose speaker so I can’t give you an opinion on that brand!

I doubt you will get that chest thumping bass that you seem to want. You might be better off looking for a subwoofer to give you that kind of bass. This Klipsh might fit your budget of 1K. Your 70 watt Yamaha would be fine with any of these speakers. What speakers are you now using?

Both those speakers that I recommended are full range and I doubt that you will need a subwoofer. If you are looking for chest thumping bass you can always add a subwoofer later on!
