13yr old speaker upgrade

Monitor Audio Silver towers (the bigger ones) and matching center. Or at lower price point, PSB Image towers (the bigger ones) and matching center, more left over for your amp.

Even by today's standard, the DM604 S3 is still a very good speaker and worth decent money used, however not much with one not functioning properly. Crossovers rarely fail. What is the sound coming from the speaker? Just guessing, I'm wondering if by going to a larger room with the system, and if you occasionally play it loud, then maybe a blown tweeter. Does the speaker sound dead, like a blanket is covering it while playing? Even if you want new speakers, it should be worth repairing the DM604's.

I'll echo what Tls49 said, but do you suspect the crossover b/c you're not getting any sound output from the speaker at all? If that's the case, I'd first check to see if your speakers have any fuses (possibly a dirt simple fix)...or, if it really is the crossover then there are plenty of very reputable HiFi repair companies out there that could easily and rather cheaply do that kind of work. All you would need to be able to do is to find a way to reliably uninstall and reinstall the crossover to allow you to send it in for repair by itself (MUCH cheaper than shipping the whole speaker). But even if that was out or the speaker was otherwise effectively dead altogether, unless you're just itching to try something new, I'm supposing you could always just buy another (used) pair of the DM604's and the one you have left over now could be your center tower, if that works for you (and the center tower is not going to be too tall for your app, assuming you're not needing to go horizontal with it). Or if you have any HiFi shops within driving distance you may want to see what you might arrange to audition, or even borrow if the dealer can be worked with (just be sure not to borrow anything you can't afford ;^) But, even if all that's out, then I do believe I'd second the Monitor Audio Silvers as well.

Ivan_nosnibor, I'm very familiar with the DM604 S3, and to my knowledge, there is no fuse, however that was a good suggestion. Cisko213, can you describe the symptoms you are experiencing?

Well I got a wild hair to switch my speakers to full range to see if I could get more powerful bass across the room. And honestly when I did this I didn't even notice the speaker was not working until I removed the grill and noticed the two lower end bass drivers not moving. I then confirmed this by switching places with the other tower and getting same results on the right channel. But with the grill on you can not tell the bass drivers are not active because I assume the JL F112 absorb the low end sound so good. Bit the tweeter and midrange worked. So my electronics buddy came over with a meter and checked the resistance across the terminals. Everything read good. But it showed an open circuit. So we proceded to dissect the speaker and checked both bass drivers and they showed good resistance on the meter. We confirmed this by connecting the speaker cables to the speaker at low volume. They both worked. My buddy then proceeded to remove the crossover internally located in the speaker. And we mocked up the connections again. And it would not pass thru to the LF speakers. My friend was very impressed with the speaker that it could be taken apart and rebuilt. And the fact that it is built with MDF. I ordered the crossover from a B&W dealer. $150.00. I have decided to keep these speakers and only replace my center with maybe a 683 or 684 tower for the center. I can't justify the cost of the CM's in that I would rather save up and invest in the D805's. but then reality is I have a 5 and 7 year old around the house. And I can already see them knocking one over running around. So maybe I will invest in a Rotel 1565. But then again I have no distortion in my sound. And I crank it when I want to enjoy a movie. The only thing I think may have happened. Was I lost the bi-wire links years ago. And when I was watching hunger games at te Onkyo THX reference level 82.0. The scene when she explodes the pile of supplies. The reciever shuts down. At low volumes it stays on. So maybe my make shift connector shorted the reciever out and fried the crossover.
