Subwoofer Problems...Please Help!

[ATegTypeR]

I recently purchased 4 Technical Pro Speakers and an amp, this is my first setup, and i must say i am very disappointed. I realize now technical pro makes low end speakers. I just saw them everywhere i went to buy speakers so i assumed they were alright. There are 2 VRTX 15's, 2 VRTX 12's and a TPro TA-4000. I hooked everything up and realized after removing a woofer there is a sound in what i believe is the voice coil and it sounds like a BB from a pellet gun is rolling arround. What could this be? How Could I Fix It?


Thanks, Matt

I experienced something similarly once. A small blob of solder was under the dustcap. I had to remove (cut out) the dustcap to get at it, clean it out. I have spare dustcaps, glued a new one in place.

Get rid of them, find someone to take them off your hands and consider the $ lost in the deal as an educational expense.

Ask here what you should be looking at:

Do not tell them what you have now, they will show no mercy.


it sounds like a BB from a pellet gun is rolling aroundThe DJ Forum guys would probably suggest it be accompanied by fifty or so more, delivered via a 12 gauge.

If it makes any sort of scraping sound when you gently push on the cone it is likely blown or misaligned. In either case it's trash. Something loose under the dustcap is another possibility - I've even had an Eminence-made speaker do that once and PE replaced it.

I did actually find a BB pellet rolling around inside an otherwise perfectly good EV woofer. It "sounded" blown when playing - but no telltale scraping and no smell. There was a hole in the duscatp. Kids....

I'm inspired actually. I'm going to make a video "how to build the worst set of speakers in the world".

The first I've heard of them is with 5000 watt amplifiers that cost $300.

Hey, that resembles my very first set of DJ speakers - except mine were in unfinished particle board boxes. Built them myself back in 1983. Long live the KSN1005 piezo!

Bose already did that but I don't think they made a video on it. Too bad it would make a unique contrast to what people do here.:eek:

Good advice if you want to fix or replace the drivers, but Bill's suggestion is the best one. Looks to me like some PA white-van speakers, so take Bill's advice. Your ears and listeners will thank you. Popularity and quality are two very different things. Bill really knows what he's talking about with Pro/PA gear. His designs 'speak' for themselves. Some rave about certain popular name-brand speakers, but the vast majority of them aren't worth what you paid. All you have to do is take some of them apart and you can see the horrendous compromises with the cabinet materials/construction and the cheap crossover components and questionable "design" that went into said crossovers. Let us know how it comes out for you if you go with the replacement drivers or AE's fix.
