The Best Speakers in the World!


The Bose 601 Series II.

At least that’s what I thought about 36 years ago.  To this 21 year old at the time, I truly believed that to be the case.  Back in those days, unless you had access to a high end stereo shop, you were not aware of many other offerings.

But anyhoo…so my girlfriend at the time was kind enough to purchase me a pair.  I had them for about ten years until I split from my ex-wife and somehow she ended up with them.  

Having not heard them in damn near a quarter of a century, I always had a soft spot in my heart for them.  The looks, the sound (though I didn’t remember the sound, I just know I liked them) and knew some day I’d want to pick up a pair.

That someday happened just this past week.  Found one locally in really good shape and priced right so even though I’ve got a ton of other speakers, thought, “What the hell?” 

Brought them home and cleaned them up a lot.  There was so much caked on dust.  I think the previous owner had them stored away in a garage somewhere.  One of the tweeters has a small hole, which I can easily repair at some point.

Set them up; hooked them up; prepared to be enthralled in the luscious sound.  Except it wasn’t at all.  They actually sounded pretty bad, like the lower frequencies were missing.  Touched all the woofers and they were moving, but these sounded quite anemic.  

I didn’t listen before buying.  But i probably would have chalked it up to the room/equipment it was in and bought them anyway thinking they’d sound different once back home.

i can’t figure out what’s wrong with them.  I’d get it if the drivers buzzed or distorted, but they don’t.  Or if it was just one speaker with the low bass output.  That I’d understand, as well.  But both speakers sounding the same?  I don’t get it.

They have dual 8” drivers per cabinet so the bass should be abundant.  I’ve got a few other Bose speakers in the house (not any cubes) and they all have plenty of bass output.  But not these.

So I got to thinking.  Can something in the cross-overs cause a reduction in bass output?  I get it that it’s probably unlikely to have both speakers’ cross-overs having the same issues.  

Then I thought maybe the woofers were replaced at some point, as opposed to being re-foamed, and the owner put in the wrong woofers (possibly not as efficient as the originals).  I’ll have to text the previous owner and ask him.

Any thoughts on what could be the cause of this anemic bass?  

Snide remarks are welcome, as well.

Thanks,

Mamoru

You commited a mortal sin. Thou shall not buy speakers without auditioning first!

In '76 and in Japan I purchased two pair of Bose 901 Series II, if you recall four channel was all the rage.  Also got a Teac A-3340-S (4 channel) and two Sansui AU-20000(s) @ 170 watts a channel.  Well, 680 watts into the Bose back in the day sounded fabulous.  Still have the 20000(s) but due to age they both will not come out of protection mode. The Bose got sold along the way.

About 6 years ago I saw an ad for a factory refurbished pair of 901 Series VI for $500. Took the guy up on his offer and amazingly they were in sealed factory cartons and all nine drivers (each) replaced with the latest version.  Bose were known to have the foam surrounds deteriorate. 

For all you Bose haters, here's a clue...play them backwards!  Such that the 8 drivers in each speaker are facing the listener.  BTW Bose does make an 801 that is used for sound reinforcement that lacks the ninth driver on the opposite side.

Mine are in my "concrete vault" as I refer to my 1000 sq ft garage.  And I can say is that there is no slap echo, they sit on top of a steel shelving unit near the ceiling and will shake your teeth loose.  Much to your surprise they do an amazing job and not just on Robin Trower or similar metal.  Dianna Krall and Patricia Barbara both sound great.  That is until you go upstairs into the music room and listen to the real deal.

Love 'em or hate 'em that's on you not me.

The 601 Series II are not like the 901s.  Rather than nine drivers, the 601S2 has two 8" woofers (one on the front of the enclosure and one atop angled forward) along with four tweeters surrounding the upper 8" driver pointed in various directions.

The audition before buying...I thought about this and I have never purchased speakers after listening.  Not a single pair.  

I've bought a few pairs new (a couple of Bose, B&W N805, Spica TC-60, Merlin TSM) but the majority have been bought used over the Internet (probably 30-40 pairs over time).  Some didn't live up to my expectations but for the most part all others have.

Related to the issue you are having.  Here's something from the 601II service manual:

4. Phase Test

4.1 Momentarily apply 10VDC to the input terminal of the speaker. Observe the polarity when connecting the DC supply.

4.2 The woofer should move outwards with the momentarily applied DC voltage.

4.3 Visually check the tweeters wiring to ensure proper phasing.
