Bookshelf/Small Speakers


Do not listen to my tube system & Thiels anymore & will be downsizing soon.  Therefore, what are some of the best bookshelf, small speakers available?  I do have a Carver M 400 laying around some where that I will probably use or possibly go to an integrate amp.  Thank you.

I just picked up a pair of RS6 Infinities for 50.00 usd I had 2 new Dayton 8" reference HE drivers.. Holy moly. What a killer speaker. That speaker will better most bookshelfs at 2-4k. AT least 92% efficient.

A MC225 is just thumpin' and clear as a bell with poly dome mids  and planar/ribbons for highs..

No kidding they will better the LS50 2 X pretty easy.. I like the LS50 just no match for the RS6s. I have a whoppin 200.00 usd invested.. All poly caps (100 year caps). 50-100.00 more on a XO rebuild.. Fun project took me 3 hours.. with a clean and wax job..

Options ay...

Regards
OP:  Small speakers.   The smallest.

I listened yesterday to a BBC Radio piece on Joni Mitchell.
At my desk where there is a cheap Dell with standard sound card and two tiny plastic speakers.  The speakers are 3.5 feet apart and not toed in at all or angled up.  My head is a foot above their plane and 3.5 feet from the line joining them.

The programme celebrated the 50th anniversary of 'Blue' so most of the music was from there.  I don't know what the BBC's source was but presumably CD or streaming.  The radio signal is digital.

The thing was that on this crudest of replay systems the soundstage stretched way outside the speakers.  I closed my eyes and pin-pointed the limits and found on the left side the image stretched fully one foot beyond the speaker.  I can also say the sound quality overall was very good.

I am very familiar with 'Blue' and have four different LP issues.  In scale, my big system with Martin Logan CLX Anniversaries doesn't stretch nearly that wide.

Go figure.
HARBETH P3ESR XD

Amazing clarity and astonishing bass from beautiful shoebox-sized speakers; the Harbeth P3ESR loudspeaker is the ultimate mini-monitor. The clean, clear Harbeth sound, in miniature.

HARBETH C7ES-3 XD

An all-around satisfying listen, the Compact 7ES-3 loudspeaker has fantastic micro-resolution and an electrifying clear presentation.

HARBETH M30.2 XD if your budget permits 
What's the budget? At the cheap end, Paradigm Atom Monitors. For about $300, great bass and good treble dispersion. Also Dali's have some in the under $1k range that are surprisingly good. At the higher end, ATC's or the new small Spendors. Need a little grunt to push them (50 WPC minimum). The LS 50's left me cold, but that's just personal preferance. A pricey used option are the JBL L92's. Nice dome tweeter and a 10" woofer. Ported and very efficient. Saw some for around $600 with new caps and refoamed woofers. 
Do your best to audition whatever you’re considering IN YOUR SYSTEM. I bought my monitors based on great reviews, and now I’m living with a sound that’s (with my rather warm amp) way too laid back for my tastes.
