  • The Dayton B652 - What on earth happened to them! (Old Vs New Stock Comparison)

    Hello all. I am not sure if nobody else here has noticed this or all the posts disappear but the very popular and very GOOD B652 bookshelves have turned into garbage. They were so good that I bought eight pair to leave in storage when they went on sale in (Dec2012 and Feb2012).

    Only after being bombarded by recent reddit posts and reviews on the disappointing quality as of late did I bother opening up two pair (one from the December shipment and one from the February) for testing. My word, these sound off. I got my oldest pair out of my closet (14months old) and did a full A-B comparison in front of a TASCAM DR-40 Stereo recorder because the difference in what I was hearing was astonishing.



    Even through Youtube's 192AAC compression and even on crappy laptop speakers you can CLEARLY hear what I am hearing. Here is the FLAC download https://docs.google.com/file/d/0Bx63...it?usp=sharing for all purists that think Youtube is mucking this up.

    After this demo I yanked the old and new sets completely apart and found every single piece had changed. The box dimensions, the 6½ driver, the capacitor on the tweeter, the tweeter, the grill, the wire terminals and wire layout and even the amount of polyfill had been cut in half. I know this isn't the first time they have changed the build, My very first set 2+years and my next set 18 months showed some changes as well but these changes didn't affect the actual sound quality. I even went as far as to change the Capacitor to one matching the specs of the old daytons and the tweeter was improved but the whole sound not fixed. So add bad caps to the mix.

    My only thoughts are PE-Dayton has completely changed their Manufacturing Partner in China to better keep up with the demand for these speakers so they wouldn't go out of stock every few months. Unfortunately this means I can no longer recommend them to people and I frankly feel bad about recommending them since the recent update where I was telling everyone how great they sounded and they were receiving the WORST sounding speakers I have ever had the unpleasant experience of listening to.

    Long and the short is if you have a pair with speaker wire and feet, you have a crappy pair. If the tweeter has a flat spot in the center dome, you have a crappy pair. If the woofer's external rubber surround is segmented instead of solid, you have a crappy pair. If the hanger bracket on the back is oval and horizontal instead of vertical, you have a crappy pair. I would love for anyone working at Dayton to contact me with ... anything, condolences, an excuse or maybe a fix/replacement for the drivers as I have been one of the utmost advocates for their gear and really don't want to see something like this tarnish the name of Dayton for GOOD and cheap audio.

    Here is my Reddit Post asking people to stop buying these Daytons which breaks my heart after all my tireless solicitation, http://redd.it/1bckzx You can see it has not come as a surprised to anyone who recently purchased a pair that they aren't the glorious beacons of hope I had promised.

    P.S. Sadly, this is NOT an April Fools Joke.

    The new speaker sounds plain defective. It's almost as if the woofer is run full range and the tweeter is a few db down or shorted. Try to measure DCR of the speaker and see if it's even safe to hook up to the amp.
    If you are in NYC and want to make it to Brooklyn Navy Yard and measure them up one of this days, let me know.

      Hey, can we figure out when the changeover happened and some easy ways to identify the "new" vs. the "old"? I am afraid I have the new version, because I didn't much care for the way they sounded even after bracing the box and adding some additional polyfill.

        They used to sound really good? I have never read that before.

            In fairness, I have never personally heard a pair. But I also have never read any positive reviews of them. In fact Zaph has a blog about how he modified a pair and still didn't care much for them:

              I can confirm these allegations. My year+ old B652's are awesome. I have a double set in my living room. I got two pairs for my room in December and they are the "new" HORRIBLE ones.

                They were around $19 when they first came out, before they got any good reviews, and then quickly went up to $25 and $30. It's shameful that Dayton would charge more for less.

                They are likely just a cheap speaker branded Dayton Audio. I doubt it is a Dayton only design.

                  Well I have been all over looking for other cheap competitors including on European sites and nothing really closely matches the dayton except these which have a different sized box it turns out. The Monoprice cheapo's are ported and have a similar looking tweeter but share nothing else.

                  If one year ago they could build great speakers then there should be no reason they can't go back and have the same speakers built now. Whatever they did just has to be reversed. They really should be refunding all the customers who bought these as they are all being bought under false pretense. I mean I now have eight pair that would be better used as kindling then as speakers.

                    "Great" B652s, "awesome". You guys are straining your credibility to the breaking point.

                      I've listened to a modified pair at the SEC diy get together and they sounded "pretty good" with a vifa tweeter and modified crossover, bracing, stuffing, etc.

                        They certainly outreached their price if can we agree on that I would be happy. I would have put them up against any $200 pair of speakers on the market. Perhaps a bit of a lacking low end with the sealed design but clarity and transparency you simply couldn't find in any entry level polk, sony or JBL bookshelves.

                          Well, so so far this is what I have:

                          Old: Phillips Screws on tweeter
                          New: Star or Hex screws on tweeter

                          Old: 2" spring terminal cup
                          New: 1.75" spring terminal cup

                          Old: mitered corners
                          New: **** joint corners

                            Yeppers, new ones are pretty subpar even by B652 standards.
                            Don't listen to me - I have not sold any $150,000 speakers.

                              The "early" B652's are serviceable with additional bracing and damping material plus Zaph's XO mod with a sub-woofer for music, just barely. They are fairly good surround speakers when modified. I haven't heard the new production in person. What I heard thru my headphones are terrible and not worth $37 a pair. MCM woofers, tweeters, some cheap boxes and a super-simple XO won't cost anymore, and can't sound as bad.
