Speaker configuration Marantz 2270


I just received a Marantz MIJ 2270 from the late 70's. Looking for speaker opinions. I tested the unit on a pair of very cheap pair of bookshelf speakers. Granted the speakers were terrible, but I could tell the system could benefit from a sub; or a full range tower with bass speaker.

I am working within a budget of about 400-650ish. My experience with high end stereo equipment is limited, but am familiar with live speaker gear. I like the punch you can get from monitors, but have to keep in mind I would need a speaker that would like a lower powered signal being I'm working with 70 watts per channel, another reason to look at smaller
speakers.

In doing a search I noticed many people felt a sub of some sort is needed. I have found a few older passive subs with smaller drivers that had decent specs. I would like to entertain a passive sub as to get more the Marantz sound versus a powered sub. I would be concerned in blending
two set of speakers not knowing if I would need a crossover or not.

Being i am a newb I may be completely off base with my assumptions.
What suggestions could any of you provide me for my quest?

Thank you in advance

In my research I have heard good things about Klipsch products. Punchy in your face with good dynamics is the common phrase I read in regards to that brand. I would def benefit from a trip to a high end audio store to get a better feel from these brands. Klipsch was one that could be found in my price range that sounded like it had the characteristics that I would find very appealing.
Vintage Klipsch KG4's ( used $300ish in great condition ) work very well with Vintage Marantz..
I've owned K-horns, Chorus, Forte, Herseys, and Quartets. The Quartets should work very well. Good luck.

I have as couple of old 2270s in my collection
Good vintage all rounder
Many of our customers have succesfully paired Vandersteen 1 c and Vandersteen 2CIs and es
You can find a clean pair of 2 series for 600 and up
and 1 series from 399- up
Having been a Vandy dealer for over 25 years these speakers offer superb performance and value.
Read the well written manual for best performance operation

Small speakers are not necessarily more efficient. Klipschorns for example are amazingly efficient and don't lack bass at all.
Passive subs will not reduce the load on your receiver and will lack a crossover with controls to help blend with the speakers. If you get a sub, get a powered one unless you buy a matched set of passive sub and satellites.
Adding a powered sub will also dramatically increase your volume level. Bass is extremely power hungry. A 200-500 watt sub can do wonders.
Final note-the difference between 70 watts and 140 watts is barely audible, about 3db. To really notice a difference in power, you would need to go up to 200+ watts per channel.
