Hi,
I am looking at making best loudspeaker I can afford in $1600-$1700 range (excluding the boxes).
ZRT2.5 seems to be the best bet at the moment but I would prefer to have it in a TL enclosure.
ATR2.5 seemed ideal but it is way above my budget due to the expensive drivers used, and I am not sure if they are so much better compared to the onces used by Zaph.
I also have a fancy for Ribbon tweeters, but not having heard them I don't know how much that would help either.
I love to do DIY, but I am a beginner in loudspeakers area. I would want to build one really nice set of loudspeaker and then move on to my other DIY plans...
Can someone highlight any proven projects which would meet my requirements, or help me with ZRT2.5 in TL enclosure & crossover?

Since you are a beginner and you want to get the speakers built and "move on" as you say, modifying an existing design (i.e., doing in in a TL) rather complicates that goal. Stick with an existing design and build it as is. Of course Planet10 may have some input on this regarding the TL.
Also I'm a bit confused when you say you have a "fancy" for ribbon tweeters yet you've never heard one - you should approach speaker building from a point of neutrality and not favor any particular type of driver (or design) you're not familiar with.
The stuff Zaph does is good - if the ZRT is too expensive look at his other designs, such as the ZDT3.5, SR71, BAMTM, ZD5, SEAS L18. Hard to go wrong here. The ScanSpeak drivers in the ZRT are arguably the best available, but there are cheaper alternatives that will give very good performance and high value.
Consider the designs here also:

I've heard the Event, and it sounded great. Bass was very strong and deep.

Would other drivers (Lower VAS, Higher Fs) work well in the Event enclosure?

I found Seas Thor here
And it's kit here at $1365
How would this compare against ZRT 2.5
And it's kit at Madisound for $1400
Seas is a 2001 design in a TL enclosure where as ZRT is 2008 design in Sealed/vented enclosure. I guess both use excellent drivers (Seas vs ScanSpeak) in 2.5 way configuration...

Maybe if you are a follower of the Danish School... and don't forget Audio Technology... the latest shop for the guy that created Dynadio and then ScanSpeak

A very good example of the Danish School, but not if you build the stock enclosure... Joe blew the TL big-time (bass to 100 Hz)

I went through most of these threads and looks like people have got mixed results from Thor design. Also there is lot of confusion regarding which one is the right Thor design, both Cabinate and Crossover are being questioned. I guess it would be safe to stay with ZRT 2.5.
Are there any reviews of ZRT 2.5? Search shows only 3 threads with ZRT on this forum and none has a detailed review...
Has anyone done this project?

Hi,
The short version of the Thor TL is the TL design is flawed / wrong.
The box woulds would work with one driver but does not with two.
The ATR driver in a 2 way works in 0.75cuft / 21L tuned to 38Hz.
The ZRT driver in as 2way works in 38L / 1.3cuft tuned to 30Hz.
Indicates a 2.5 way ZRT TL is going to be very big ......

The TL as desogned by Joe d'Appolitti is flawed. He measured it with a single driver (twice). SEAS measured in their anechoic chamber -- bass to 100 Hz more or less.
FatThor, ShortThor, and SmallThor are all redesigned TLs that work (none of them are short or small). All are Mass Loaded.

I have not heard either design so cannot give you a subjective opinion on the sound.
The guys here did a great job at improving the cabinet. Jimangie1973 over at htguide:

Reworked the crossover which needed improving too by the looks of things.
Essentially - if you really want the Thor - order the drivers only - then make the cabinet as per posts planet10 provided and crossover in the above link.
Zaph rates both the Seas Excel drivers (as used in the Thor) and the Scanspeaks. For the ZRT - he's chosen the Scanspeak drivers for a no holds barred 2.5 way. That should speak for itself.
