These seem a bit pricey $$$

More than half the cost of a commercial loudspeaker is marketing costs. You’re generally not paying wholesale price from the manufacturer. If you’re buying from a local audio shop, list price is a 40% markup from what they pay for it, and they’re often not getting it from the manufacturer, but from the distributor, who is also representing other manufacturers as well. So you’re paying the distributor’s markup. This means that the price you’re paying is at least 2 times what the manufacturer is charging and probably a bit more than that.

The manufacturer has to charge at least 2 times their cost because they’re in business to make a profit. Yep. If they don’t make a profit, they don’t stay in business. So this means that the cost to build a loudspeaker is about 1/4 of what you’re paying.

There are any number of excellent loudspeaker kits available. The engineering has already been done. The magic is there for the taking. The comparison I love to show is the Joseph Audio PERSPECTIVE2 Graphene, which retails for about $12,000, to the SEAS Thor kit, available from Madisound for $1,993. Depending on how you do the project, you can spend another $400 to $1000 on building them.

Even if you don’t see yourself as a woodworker, a loudspeaker is a very easy cabinet to make up. Any local cabinet maker can knock them out for a reasonable amount. The hardest part of making any loudspeaker is making it look good. You can have the cabinet maker put a veneer and nice finish, or you could take the cabinets to an auto body paint shop, like this loudspeaker:

and they could come out looking incredible.

And if you’re thinking about dropping $12k on a loudspeaker, then you’d do yourself very well to think about this Thor kit.

30hz bookshelf? not likely

Kenjit, my bookshelf speakers measure flat from below 30Hz up to 20kHz (in room).
Using a Peerless HDS 6.5" in a ported box for the midbass.

The New top Wilson flagship speaker  $750k, I would consider that slightly overpriced , to say the least , and I thought  the Great    MBI 111 Radiastraler ultimate was expensive approaching            at $200 k.

Thats not impressive. A devialet phantom can do far better than that in an even smaller box. 

The Wilson Watt/Puppy 3/2 sold for $12K when I first saw (and got to hear) a pair in a local store. They were very solidly built and had a reputation for being "bullit-proof"- playing VERY loud without distortion.
When I listened to them I could not locate their position in the room, which was a 1st time experience for me. Down the road a bit another dealer demo'ed a different speaker to me made of much less expensive cabinet materials. However the technology #2 used was also very different, and sounded extremely good as well- maybe even better in certain respects. It retailed for 1/3rd the cost, but- it didn't look all that great- the good sound came from inside the enclosure, and the outside was mostly a black-cloth covering the frame (no, not Vandersteens).
Both companies are still around today, and to be frank #2 is now very expensive also. But Aesthetics play a role in what you want in YOUR room,
and speakers make more of a difference than any other single component. Somehow Magico Q-1 bookshelfs just HAVE to be miraculously good,
and if they're not I would be very surprised, even disappointed. Don't ask me why- it would be like someone telling me all that effort designing them was done by an engineer that doesn't listen to a lot of music themselves when they go home. Are they worth all that money? No, and Yes- and....Maybe. But it would HAVE to make beautiful music and make the person that bought them extremely happy. For me it would have to blow my mind when listening to chamber music or a well recorded piano. But it's ALL crazy, even my talking about two little metal boxes
that cost more than my last car. I am just in love with all the beautiful sounding instruments played on records these days (not to mention voices). OTOH, as for CGI movies played on 4K televisions, many of them don't entertain me, so I can get by with a much more basic video system.
