Clasicalfan is correct, I should modify statement-
'' However when we speak about high end level of performance DIY projects available on internet cant touch good comercial brands. And price performance ratio is much worse.""
I didnt wanted to say there are no better high level DIY eforts than hihg level comercial ones. I just compared what was available on the internet from well respected(by diy comunity) diyers. Sorry for not being clear at the very begining.

This is a recent example of the upper end of DIY

Given the cost of the drivers that Pida used, if this system were put into production it would probably have a retail price of $22,000 to $30,000.
Given the measured performance, I suspect it would compete very well in that price range.
The OSMC is another example that has been refined and evolved over a long period of time, and is currently at a highly sophisticated state. It has been heavily measured by multiple people. The performance is very high.

Not to pollute the thread, I just want to show the level of my DIY "commitment" to prove that I'm not pulling my words entirely out of my ****. My DIY "Audio Note" M3 phono boards. One on Ebay knock off PCB one on bakelite board. After I made them, I was little more hesitant to criticize AN commercial pricing. This, while my fridge broke two years ago, and I didn't feel like getting another (sucker broke 2 years after the purchase and it is a compressor so no DIY repair) Food in the city is available 24/7 so what's the reason for a fridge really? And my car pushes 250k miles and 20 years BUT I thought that buying a phono cartridge is a better idea and I'm too old and ugly and girls won't **** me either way, better car or not 🙂

I was writing crossover simulation software before I had internet access. I may have missed your point?
Wonderfully measuring Japanese amplifiers from 80's come to my mind when I read this. To this day an engineering types on various audio sites are convinced that nothing better was ever produced and the rest is just smoke and mirrors 🙂 At the end of the day every p....y is just the same. That's what my married to high school sweethearts friends are telling me and I confirm it solemnly. There is no use to say otherwise....
You sure are right about the lounge. Let me rephrase. In one aspect commercial reigns: the vendor succeeds in making the business case. By using whatever comes to hand to get things sold. And that is not sound quality. That aspect has proven to be a minor asset in selling speakers.
Apart from that sound quality is a subjective term, I mostly agree with markbakk, but there's still one thing missing when it comes to DIY speakers: the availability of a test/audition. One gets to know how it performs only after he's finished building it, whereas in case of the commercial unit, both the product and related information are usually available long before he pays the money.
Now, there are products that don't have (proper) datasheets, but I prefer to remove those from the equation, as they're usually not very well-placed to challenge the market leaders / skilled hobbyists in anyway.
Similarly, some DIY designs seem to provide data (curves etc) beforehand, but the possibility of an audition is just something else. Since most buyers are not scientists, they may not have enough knowledge to assess everything from curves/data or they might just want to listen, in order to remain on the safe side and not get deceived.

Sound quality has been researched enough, so that one safely can use starting points from that. But of course taste and perception play a major role. Not only for the casual buyer, but also for passionate and educated listeners/developers. And we shouldn’t argue about taste, should we?
Unless you listen first, it will always be a gamble. You can never tell how something is going to sound just by looking at graphs.
Hello
I was just surprised. Most people have purchased at least one pair of commercial speakers at some point. I tried DIY when I was young then purchased commercial then got back into DIY latter. So I have always had a commercial pair on hand even when I was young. My father had a couple of speaker pairs in the house.

How many people here can actually make substantive modifications to their listening room or have the funds to build another for the purpose?
you know very well ,doesn't existed a 15" FR some year ago 😛
well my d2010 still in production but now we have wonderful unit just look at purifi or SB cheap but really good
You're not looking very hard. I can think of a couple that are superb that cost more than that, and all the cabinetry was DIY. Hell, the replacement cost, landed and taxes paid of the midbass drivers in a new project I have penned for after the move will be about $A3000 (I already own them, they're being repurposed) before shelling out for the LF, MF and HF drivers, DSP and amps.
Cabinetry will also be 100% by me, and my partner's new CNC.
Of course, I've been doing just that for many years. My point was that most people can't change rooms substantively, and the majority of designs here are very wide dispersion which, depending upon your preferences, can make it very hard not to have the room be the dominant effect of the final sound at the LP.
@Brett: I agree, it is there that DIY can make the difference. Make the speakers suit the room to get ahead.

I saw an interesting room acoustic DIY project with a patio like structure, which would not cost more than 2K, and it is movable. I would install diffusers at the back of the room instead of absorbers, though.
