Def Tech BP 2006s

[olds]

Seem to have blown the crossovers in both my 2006s. The tweeters don't work in either but do work when taken out and hooked up to a source.
Odd thing too. After I put them back in the cabinets and hooked up the positive wire, I got low audio through the speakers. This is without the negative being hooked up.

I have a CLR 2300 for a center channel. Wish I could find two more for cheap and use them for L and R.

One of your built in powered woofers on those broke within the last year too, right?

Nope, it was a mid range. So far the woofers have held up.

oh that sucks 🙁

Have you opened up the speaker to inspect the crossover? If it is just a blown capacitor you might be able to fix it no problem for cheap. I take it you have owned the long enough so that they are out of warranty?

 

[olds]

Ya, they are out of warranty. I did open it up. There are a lot of electronics and circuitry in there. I guess because of the amp. I emailed Def Tech. They usually answer pretty fast.

Is the speaker's crossover on the plate amp as well? I don't know if DT integrated the subwoofer's amp and speaker's amp together?

Definitive usually is pretty good on the email responses.

I've talked to them about my BP2002's a few times during the ten years I've had them.

I didn't see anything that to me, looked like a crossover. I am waiting for Def Tech to get back to me before I go further/dig in deeper.

Got an email from them.
They are going to send me two crossovers. For free.
That's pretty nice for out of warranty speakers. :thumbsup: :thumbsup:

EXCELLENT!

This is why it is important to contact the manu. 🙂

Unless has a capacitor has blown - a highly unlikely event - I can't imagine the crossover going wrong. Unless it has some sort of overload breaker or other odd addition, there are only three things: capacitors, which if using an electrolyte can dry out and fail but only will do so if very old; resistors, which can melt if severely overloaded if the amplifier passes a massive DC current, or inductors, which are just like resistors but even more immune to overloading - while it's theoretically possible to burn off the insulation on the windings, you'd end up burning off the the rest of the speaker as well.

Have you checked your woofers? There may be a short in the voice coil, which is causing your amplifier to trip its' protection relay and disconnect that channel. The low pass section of the crossover will usually have nothing but inductors in series with the woofer, which have a DC impedance of a tiny fraction of an ohm.

I only removed the tweeters and the rear panel. Do I just check the woofers/wiring for signs of damage?

Check everything...you might have a short somewhere that fried the crossover network in the first place.

Let me guess, yours were made in PRC? Def Tech took a huge nosedive in quality when the relocated their factory offshore. my 10 year old BP-2000TLs, BP-10B and CLR2000 are kicking just fine.

no, the crossover network is not part of the sub amp. The mid and high are still powered from your receiver/amp. The built in amp is dedicated to the sub.

 

[olds]

Not sure where they are made. The 2006s and CLR 2003 are about 6 - 8 years old. I have only had the BPXs for about 3 years.

Remove the woofers. Connect a multimeter to the inputs. If there's less than 3 ohms DC resistance, you've got bad woofers.

Tested the woofers. They were 108 and 112 ohms.
Put in the new crossovers Def Tech sent me and I am good to go.
Thank you AT and Def Tech.

Time to play some Ministry on there 🙂

Most reputable companies will do this. The parts are pretty inexpensive as well. Now let's get to WHY you blew the crossovers?

I've melted many a crossover and it's always because it was too loud or the amp didn't have enough power. Also just overheating by listening too loud for too long.

Just trying to help him from doing it again. 😉

According to Def Tech, I blew them because I play them too loud. I do crank them. Pink Floyd and Led Zeppelin make me do it.
IIRC, the speakers are rated at 250 watts and my receiver puts out 120 watts at 8 ohms.

They made me promise not to crank it too much.
Last year, I purchased a CD (Robert Plant, Now and Zen) off of Ebay that's probably a cheap copy. I caused clipping which blew one or two mids, I don't remember exactly.

odd, 120 should be enough... exacrly how loud were you playing?

Well, my decibel meter is dead, it was as loud/far as the Denon would push them. Say 90% all the way up.
