Can I get a number or location for the Duratex guy?

Who are the dealers for JBL and QSC right now?

Im looking for a passive set up for my bedroom. Have 75 watts per channel.

Heard a pair of QSC K10's this weekend and was very impressed with the sound. Im very fond of the JBL eons as well but both that QSC and JBL are powered boxes. Looking for something with similar quality. Saw QSC and JBL have passive speakers, want to get a demo and see if any meet the requirement.

Anything you guys care to recommend as i'm looking?

I think JBL dealers are rent-a -amp and cet technologies in maritime plaza by the round about.

Morning guys,
Is it possible to share the power directly from a powered speaker to a passive speaker (sub)?
I recently sent in a powered box to repair and it came back overpowered. So I was thinking, rather than waste this awesome power or blow the drivers, maybe I could add the additional speaker.
Suggestions?

DJ Q · Postby **DJ Q** » June 16th, 2016, 8:56 am

I don't see why this can't be achieved.
The only problem I see is that internal amps usually match the resistance of the speaker.
By wiring another speaker chances are the impedance will either be too low for the amp to function or may be too high to take advantage of the extra power.

Recommend a good brand OTHER THAN 1200 technics
to use serato.
BTW ah looking to buy a pair of turn tables.

just set ur gains properly amp would stay cooler annd not clip...as someone said adding another speaker will change d ohm load

What do you mean by "it came back overpowered"?
As long as it's the same amplifier inside the box, this is not likely. What happened was probably that the technician interfered with the gain structure inside the box, so now your volume setting may be lower making you think that the box is now more powerful when in fact it's just that the box will actually max out at a low setting.

Another thig that could've happeped is that the input was mistakenly set at the 'microphone' setting instead of 'line input' effectively making the gain much more sensitive and you will think that box is more powerful but in fact it's just expecting a lower input signal.

Anyway to directly answer your question, that would be a no. You may very well damage the amplifier by adding load that it was no designed for.

If he adds another speaker in series he will be getting even less power out because now the impedance is doubled.

Postby **nervewrecker** » June 17th, 2016, 11:33 pm

Doable, but if power is a concern, nha.
Not sure about output as he now has double the cone area.

I only sent the plate amp for repair, the tech told me he couldn't find the exact component that had to be replaced, so he substitued it. So yes, while it's still the same amp, the output is higher.

made up my mind on some rp-160m speakers yes.

Driverack PA+ problem. Everytime the unit warms up, it starts giving the weird output. The noise only comes from the Driverack, I had the source unit switched off while recording. The mixer is not at fault because the noise goes away once I power down the Driverack.. if i let the unit cool for a while, it will resume normal operation.
Anyone ever come across such a problem?

Rene ent you from GASPARILO now? I am in allen street. I would like to see this problem first hand. But anyway, I am seeing as you raise the mixer volume, the noise increases am I right? Also I am seeing the input LEDs on the driveerack illuminating in sequence with the noise. These factors tell me that the noise may be before the driveerack, but I may be misinterpreting the video. What if you bypass the rack totally, I mean, go from the mixer straight to ur amps. Do you still get noise?

Kasey · Postby **Kasey** » August 3rd, 2016, 9:47 pm

Check me if you are getting trouble, I may be able to sort this out for you, even if it means upgrading the firmware in the driveerack.

I'm from Harmony Hall, not far from you.

Wait, I was mistaken in the sequence in which the equipment is connected, nice spot!
Kenwood source unit - Mackie Mixer - Drive Rack - Amplifiers

When I switch off the source unit, the noise remains. BUT I never tried switching off the mixer to see if that stops the noise. I believe you have it correct there. Tomorrow I will give the system another run and try to isolate the mixer and see if that solves it. Will update accordingly.

3stagevtec · Postby **3stagevtec** » August 7th, 2016, 11:53 am

My Mackie Mixer ProFX4-V2 is responsible for the noise. When I switched it off, leaving the Driverack PA+ on, the noise went away. Unplugging the source unit from the mixer made no difference also. Think it would be possible for a local electrician to repair such an issue or would be it best to just replace it? Didn't think a brand like Mackie would act up so quickly..
