LCR & Sub for $1500

I just sold my entire AV123 setup (well still trying to get rid of a pair of bookselves - RS150's) and am seriously considering going acoustically transparent screen with an LCR arrangment. I am thinking a DIY approach will net me the most bang for my buck and since the speakers will be concealed the appearance isn't as critical now.

LCR's - I would love to get something going like the JTR Triple 8's and haven't seen anything in the DIY kits that resembles this. I don't have a boatload of cash so I need to be efficient with my money. I have a friend that is willing to build the cabinets so I am not worried about that. I would prefer pre-assembled crossovers but given big enough cabinets and a good layout instruction manual I could attempt crossover assembly to save money.

Any ideas for the LCR's? - PICKED ECONOWAVEGUIDE DELUXE VERSIONS!

Finished Product


Subwoofer - I see the current rage is the THT's so I think I would like to try one of these as well. Average cost is about $400, but I already have a spare amp channel so the cost is down to about $200.
Almost done with it!
Current Progress:

Going to base my build around BFM's Tuba HT sub so I don't think I need to or can post any pictures of the render. Once I start construction I will post a few pictures...it seems there are a million build threads for THT's so I will probably only post about it if I have questions and when I am done with it.

So the econowave...first time I have heard of it in that name..is essentially what Tweak City is releasing in the Pro-10.

TCA Pro-10


What sort of impact does adding a 10" woofer in the speaker add to the overall sound as opposed to the small bookshelves from Hsu for instance...



I think I want to try a THT for sure. It sound like a fairly easy build and the price is right that I could do two of them in a fairly short time and it sounds like it would easily best my previous two subs (MFW-15 x 2).

What I want is some volume without distortion from my front three. I tend to like a smooth, slightly laid back sound but don't want to suffer clean, crisp dialogue for movies.

I want to be able to crank up some Concert Blurays and also be able to hear the lyrics. Does any of that make sense?

I guess I was assuming that someone had found a similar driver/crossover configuration that was acceptable, cheaper, and appeared the same in a cabinet the same size.

I wasn't trying to infer that JTR was making a giant margin.

Any thoughts on the eWave versus the Pro-10.

TCA is trying to sell the Pro-10 for about $350 each plus shipping. You can build an EWG for cheaper but it seems like it may require some tweaking of the crossovers from what I am reading.

Care to explain what constant directivity is in laymen's terms?

It seems like the EWG designs I have seen utilize several different waveguides. Perhaps they all are constant directivity?

That is what I was looking for! Thank you for the very clear and simple explanation.

Any change of modifying the eWave designs to put the waveguide outside the enclosure? I think that looks pretty sweet...like this:

I decided to bite the bullet and dive into the EconoWave Deluxe version. I will be mounting the horn on top of a 2cu. ft. enclosure for the Eminence driver down low.

The compression driver is sold out but I have some time to figure out how this all goes together.

I just wish the THT discussions would figure out the best way to go for my bass...but looks like I will be busy soon building!

What amp are people using for the THT??

MusiciansFriend has a sale going on right now...15% single item with coupon "BREAK".

Might be the right time to buy...Thanks!

Anyone? Thanks!

Well started putting together the crossovers for my EWaveguide Deluxe LCR's!

This took me about 1-1/2 hour. Took me awhile to figure out my new butane soldering iron...cord free is nice but the fuel burns pretty quick. I am a complete amateur so don't rely on that review as your only source. $12 was the right price and plus...FIRE!

Anyway....here is where I got:

Closeup of one -


Two 50% done -


One about 90% done - (forgot about the L-Pad wire connections so three wire connections left!)


I think another 1-1/2 hour tomorrow night should finish the crossovers. Then I will check them to make sure my bogus soldering skills didn't render them completely useless ( ops: ).

I will probably start the woofer break-in process as well...plus tell my cabinet builder he needs to get to work!

Well that figures...darnit.

Looking at the picture of the deluxe crossover:



The only difference I notice is the stacked resistor, which I don't see in the schematic or the shopping list, and the jumper wire across C3, which I guess I should probably add.

I must be having a dense moment...how did I screw this up exactly?

Where would the fun be in that?! I am a complete noob but I want to try...I also have reading comprehension problems when there are pictures involved!

I will see if I can fix it without messing things up...I cut the leads already on the back side.

If not...it will be an expensive mistake ($120?).


And in order to do that I would have to completely swallow my pride and show you what a crap job I did...I was more planning on getting components in right spot (first!) and then testing with drivers to see if the connections are solid...that way I can at least act like I know what I am doing around here.

Let me have a chance to prove myself totally inept...

Why in the description did you go for 20W heat dissipation and then describe the procedure not including stacked resistors?

Bought some solder wick and a de-soldering bulb...let's have a go at it!

Is that what you were talking about? To be honest...I hadn't seen those directions before...I assumed the deluxe changed values and not layout...you know what happens when you assume.

I will wait for confirmation before continuing with the other two boards.

Thanks!

That makes sense...these will be in an HT that is about 20x14 with little ones so I barely get to listen at reference and it is usually for short bursts before the wife comes downstairs. I was planning on stuffing the box with fiberglass so it sounds like I shouldn't expect any problems, but I should be aware of their potential.
