Caladan by Clayton Shaw DIY

clayton spec 1khz 2.order on the tweeter, how can this or any other dome handle that? even most 1" exit compression drivers dont.
the seas in the orion was pressed as low as possible 1.4khz 4th order i think? and thats an expensive tweeter.

I really doubt the Dayton tweeter is capable of that without having significant distortion down low at the crossover point. I would personally use a deep waveguide to obtain that waveguide gain to push the distortion lower. Augerpro has an 8 inch waveguide for this specific tweeter which can also help time align to the woofers as well.

What would it be a better replacement?

 

[AllenB]

even most 1" exit compression drivers dont.

Most 1" exit compression drivers can be crossed below 1kHz and many here do that.

 

[multitask]

well you can if you want to, lowering its power handling and run it into its own resonance freq.
can you think of any commercial design doing that?

 

[AllenB]

I don't have a problem running below resonance.

 

[multitask]

you could drive a ferrari on a dirt road, but that doesnt make it a good idea
power handling will be cut also. for example over here, simply lowering a d220ti from 1500 to 1200 LR2 on a jbl pt (using a dsp) significantly increased the number of broken diaphragms.

The Emerald Physics CS2 comes with d220ti with active crossover set to 1k 48/LR.

You must listen LOUD.

I haven't had to replace my d220ti diaphragms in my EP CS2......ever.

Inspired by New Record Day video about the Caladan by Clayton Shaw, I decided to do it DYI since shipping costs to Japan are ridiculous (and no international deliveries at the moment provided). My MiniDSP serves as an active crossover for two ICEPower 125ASX2 amplifiers. They sound amazing, using a Linkwitz-Riley filter 48db at 1kHz and some gain in the low end, Never thought open baffle speaker can have such a lot of low end, while the speaker membrane is barely moving. The speaker disapear and you feel like in a live concert. This works also for my music with distorted guitars, not only for the high end demo music. Bass guitars sound so real. This is the first day listening to them after waiting 3months for the delivery of the 12inch speaker drivers....I guess no burn in needed. Clayton Shaw chose the perfect drivers.....

Have you inverted the polarity on the tweeters like in the picture?

 

[Chemarcelo]

I have completed mine. After about 200 hours burn-in I try them and don't sound that good. For that reason I was trying to use a mini DSP 2x4 HD. Any suggestions?

 

[AllenB]

Integrating a speaker into a room is a potentially lengthy process of dealing with acoustics resulting in moving them around and using EQ where that is possible. If you're not sure what to do, at least experiment in those two areas.

 

[mordikai]

Imagine that, new record dork or audiofluffer might have over hyped these?

Beautiful build. How did you come up with the XO? Have you tried measuring a speaker from listening position to see at least the bass is working within reason?
