I came into possession of a pair of unaltered Dayton Audio T652s recently ...
By themselves they're not that bad. Hardly "high end" but not entirely unpleasant to listen to. They had all the typical problems of cheap speakers... uneven frequency response, harsh treble, even some bass end stuff going on, but overall they were quite listenable. I judged them to be adequate for applications like sound bar killers or a den system, when used with a mini-amp but definitely not suited to a listening room or home theatres.

Well these guys turn out to have a pretty decent hard dome tweeter and a pair of not entirely bad 6.5 inch mid-base drivers. I wasn't ready to rip them down for parts just yet and these things are cheap, under $200 for the pair... so why not have some fun?
1) I took them all apart, re-glued the inner seams and was pleasantly surprised to find bracing in the cabinet which also got some extra glue.
2) I replaced the spring clips with a binding post cup.
3) I tossed in an OTS 2 way, 2nd order crossover that I got for $19.00 a pair.
4) I filled the cabinet with loosely packed PolyFill up to the bottom woofer.
5) I later added a second inductor to the lower woofer to roll it off a bit early creating a sort of 2.5 way system.
Now, since taking them back in on trade, I've been listening to the altered versions for about a week... and guess what... they're not bad. They might even displace my Cambridge Audio speakers that cost twice as much.
The crossover details are below in thumbnails as are the DXO files for them. I didn't have the actual driver specs (they don't have part numbers on them) so what you see in the graphs isn't exactly what I got...
What I got is shown in the REW plot, also attached. There is a fair bit of room in there and my cheapo test mic rolls off around 6khz, but they still did surprisingly well...
Listening to the lower woofer you can hear bass that it rolls off at a relatively low frequency, 400hz or so. The upper woofer carries both the bass and the midrange up to about 2khz then the tweeter takes over for the rest.
All in all it's a nice clear sounding setup with a wide soundstage and surprisingly good bass.
Just don't expect them to take much power or play really loud... that's where these guys hit the wall.
So, has anyone else played with these and how did it go?
