Wait what seriously. Only 5db drop up-to 20kHz at 60 deg Horizontal. Whaaaaaaaaaaaat. Are all ribbons this crazy or just the RAAL. Tell me God had direct hand in making them.
For HT who knows as I never go there, but for 2-channel I respectfully disagree. speakers 1st everytime as that IMO is wise $ spent no matter what. 2nd best money spent is PEQ be it analog or digital & preferably into active speakers. I don't even turn on my digital PEQ & much prefer analog PEQ which is completely set & forget. I would put that 10k on used active ATC, Neumann, Dynaudio, Genelec, etc & not have any other gear or room treatment except streamer& DSP PEQ & would destroy a previous 2k speaker anything, room treatment or not. Just my opinion based on my experience's.
This is an example of how you can build the same for less... The top and 3rd speaker down are the same Scanspeak Illuminator 18WU's I use. The tweeter second down is also Scanspeak and costs around the $500 mark. There is a lot of electronics in that price as they are active open baffle, but that is a lot of built in profit. From memory all the lower drivers we AE.
I don't know if they are the figures, but the off axis response is definitely decent. I tend to sit right in front of them to listen, but as I say the drop off when in the kitchen is no where near as bad as what you might hear from other tweeters. But the off axis response is not their strength the pure crisp music that comes out of them is a delight. The ultra light foil they are made out of make it nigh on impossible for any conventional speaker to come close.
I have heard others like B&G, AMT etc etc but nothing sounds as pure as the RAAL. It's like honey in your ears.
These are the guys I am excited about getting out of the box. https://www.madisoundspeakerstore.c...l-140-15d-ribbon-tweeter-with-amorphous-core/
Not necessary since my take on DIY is somewhat different from building other people's designs. However, here's some good news for you, amplifier with built-in DSP, no extra processor required.

Only 2 channels you are going to need an awful lot of them. Minimum 3 if you take one feed of each side, 4 if you want to dedicate them to each speaker.
While it looks good on the surface it could be a wiring nightmare if you don't have a way to split up the source signal.
Actually, the wiring would be much less than having a separate Behringer / DBX processor and three stereo amplifiers. Besides, it's all pro-gear and in fewer boxes, with much better pricing, for saving some money.
How so? I have a single digital RCA cable going from my source to my active crossover. From there it has 4 outputs per side that can go to any amp combo you want, I have six of them going to one amp. The problem I see with multiple amps like that with the DSP built in is splitting up the source signal to feed each of the amps a part of the source signal.
Three amps with input imedances of 20k in parallel would result in a net impedance of 6.66k which can be easily driven by the buffer op-amps within most audio equipment. With the processing unit in between you need intermediate cabling (in addition to your input cable), extra power cable and rack space for the same. Reducing cabling would also reduce tendencies to pick-up noise / EMI.
Besides, it is also worth noting that this appears to be a linear amplifier (class-H) with a conventional power supply and not a switching amplifier (class-D) powered by an SMPS.

I think what he means is that there are no additional cables between DSP and AMP in that case. I can run direct speaker wire from it.
Amps could be assigned band-wise, as in low, mid high, with stereo linking turned on to adjust both channels together, from the same unit. The delay in each band could also be different in order to provide time-alignment between the bands.
This is kinda costing more for single channel than what I was going for previously. Previously I was totaling DSP+AMP to INR40,000 per speaker/channel but now it will be INR52,000 per speaker/channel.
Except your previous total was missing an audio power supply, chassis, fixings and various other bits and bobs. Any reasonable figure for this would make it more expensive. A more reasonable choice of amplifier module for the tweeter channel rather than a 2 x 315W Class D one would likely bring the cost down. Plus no doubt one or two other things that would come up if you considered how to put something together that works. On the other hand, with the proamps option do you want to listen to fans and/or are there mods that genuinely work to make them acceptably quiet for domestic use? A reasonable comparison requires some care and thought and even after making the decision one is very likely to find one or two omissions and/or things that are not quite right when work on the implementation starts. All part of the fun of the hobby.
You don't need three outputs, you just need to feed the same output to all the three amplifiers alike. Each of those would separate and amplify their respective frequency band to power the respective speaker, simple.
Low = 26000/-
Mid = 26000/-
High = 26000/-
---------------
Total = 78000/- for all processing (crossover, EQ, time-alignment) and amplification upto 450W per side, professional grade stuff.
Now, add your favourite drivers and other expenses and I promise you that things would still fall short of 2,32,000/-. Besides, such an arrangement would accommodate almost any combination of drivers in the market, including studio, PA or even cinema speakers.

That 28K cost for AMP was including all that. The Modules themselves cost 26K. I plan to pack it in 8ch enclosure. So 2 Speakers running off of single rack.
But yes will do more research anyways to cut down on cost. Not like this is Final or anything. I am always open to suggestions.
Wait what those are just Amps. Not DSP. I thought it was 2 in 1. If I have to separate Low Mid High before feeding the signal into them then I will need DSP before hand. Or are you saying that I should split the Signal from AVR into 3 Using some kind of Splitter and then use Three of Those to Process and Amplify.
But wouldn't the signal that is being passed through be affected by usage of 3-way splitter.
And have not found a single decent quality one yet. XLR to XLR 3-way splitter

It's not splitting, its feeding the same voltage into multiple units. Each amplifier would see the same voltage at its inputs, but still work on it differently. There is not going to be any questionable deterioration in signal quality, as is often seen in RF/CATV terminated splitters.
Being a DIYaudio member with long experiences in electronics, can't you make a nice little proper "splitter" yourself ? Is it really that hard ?
Now your per channel costs should be at INR 39,000, and that is using retail equipment (only), with power supply included.
