Sierra

Another Troels Gravesen's DTQWT Project Build

Recommended Posts

Hi All,

Not too long ago I decided it was time resurect my home audio system that I had done nothing with for the last decade or so.

One part of the resurection process was the purchase and building of a new valve amp kit.

Once the valve amp was built and some listening was done it became obvious that my 30 yo speakers also needed some attention.

The speakers are 3 way bass reflex with a satelite midrange & tweeter arrangement which in their day sounded really good ... although there were always a

couple of issues with bass output rolling off in the lower registers and fatigue setting in after prolonged listening.

Yes ... definately time for a change.

First up I had a look in the SNA for sale section to see what was around and within my budget ... not a lot was there at the time.

Then I thought DYI ... and Troel's website came to mind and the fact that I hadn't visited it for a couple of years at least.

I was really surprised when I saw how many different speaker designs he has now ... and I got excited when I saw he had a range of "High efficiency"

speakers desighned for valve amplification.

First up I looked at the TQWT project and thought yeah ... this is a nice looking speaker and just what I was after.

... and then I saw it ... the DTQWT!!!!

As I read more about the DTQWT the more I knew I had to build it ...

Then I started reading the user builds of the DTQWT from around the globe and the great comments it was recieving.

One of those user build links brought me back here to buzz lightyear's DTQWT build thread.

After reading all the great comments from all that have heard his speakers I knew I had made the right decision ... and time to start the ball rolling.

So I contacted the kit distributor Jantzen Audio in Denmark to place my order ...

I wonder what could be inside??

nice

I wonder what the total cost of the parts is landed and what kind of budget is needed for the complete build please?

It seems like smart way to use your money as it minimises shipping expenses of big boxes.

This is a serious kit. i went to local hifi store the other day, how astonishing that $10k plus speakers and $$$ equipment only can achieve so limited performance with many flaws. i can bet this kit can beat any speakers out there on any price. :cool:

i hope someday i can get to listen one of great design by troels such as this.

Looking forward for your "personalized" troels's design :) , i saw few varieties that really absolutely beautiful.

regards

There are price lists on Troel's website for the various component options.

The Eminence drivers are available from a number of different websites with prices listed.

Depending on where you source your components (overseas or local) you may need to factor in freight costs.

Then you have costs for fabricating the cabinets ... materials and or labour.

It's not a cheap project ... but it gives a lot of "bang for buck"

Very nice, I'll be following this thread with a keen interest.

So will I ... I'm keen to find out how it turns out :lol:

awesome.

just finished my dtqwt build.

your in for a treat!

Nice work with your build James ...

Are you still running yours in?

That's some very nice quality parts used for this build. Best of luck and keen for updates as you go!

Thanks tuyen :)

following with anticipation!!

I'll probably bore everyone with lots of pictures :P

Check out speaker bug in Queensland he sells the dtqwt kit. Good luck with the build.

Thanks Pat

Yes speaker bug does supply the kit locally ... but does not supply the 13mm felt or the polyester foam.

Thanks henry

I'm sure you'll get a chance to have a listen to one of these at some stage ... seems like there are a few builds out here in Oz now.

And definately some of the "personalized" builds out there are beautiful pieces of furnature.

Yep been running for a couple of weeks.

I got the foam sent from jantzen and the felt off eBay.

I would love to finish in white gloss. Maybe I can get a laminex veneer. But for now I'm enjoying the fruits of the hours put in.

You can get all sorts of veneers ... laminex included.

There's a few builds that have been done in white and they look good.

I had the pleasure of hearing buzz lightyear's on the weekend ... very nice indeed ... now I can't wait to get mine built.

Pat ... thanks very much for your hospitality ... and very nice to meet a few other SNA'ers Dave, Keith & Jan.

Been a while since I've made any updates ... but there has been some progress made.

First up ... Looking at the Eminence Deltalite drivers they needed a bit of work to the bolt holes.

post-103929-0-33446400-1348499494_thumb.

As can be seen here the bolt holes are half covered over with the edge of the surround.

Nothing that a little rat tail file cant fix

I have to admit that I'm sorta kinda cheating a little bit when it comes to building the cabinets.

I'm getting a friend of mine who is a cabinet maker to build them for me.

I want these speakers to look like a nice piece of furniture when finished ... however I don't have the wood working skills or tools to do the job to the level that I want it done.

The cabinet itself is made of mdf and finished of in Tasmanian Oak vaneer.

The front baffle is a combination of solid Tasmanian Oak & Jarrah.

The front baffles glued & biscuited together
