They would retail for serious money, especially if you do a really good
/ nice job on the cabinets, some mechanical engineering skill is needed
to build very performing cabinets, as opposed to just looking nice.

Performance wise miniatures are not in the same ballpark.

Your suggestions in post #8 were good ones. Here, it's unlikely those behemoths will fit on the shelf the OP had in mind. :-(

Hi,

Good "bookshelf" speakers invariably sound awful placed on shelves,
they are designed to be placed on stands in open space, and I for
one think floorstanders are a best use of that open floor area.

There are AV speakers and some small hifi speakers specifically
designed to be used near walls, corners and on shelves, most
so called nearfield monitors fit into this category, but they
simply don't sound very good with such placement.

For HiFi IMO there are "standmounters" or "floor standers".

rgds, sreten.

Given Sretens comments on the resale value of small speakers I would offer your friend $250- as parts value for second hand drivers; about what they would fetch on eBay. Then make some nice new boxes for them

Hi,

I doubt only the drivers (and all the other hardware) is recoverable.

I don't know what the damage is, but if its cosmetic and the baffles
are fine, new boxes seems an overkill, just fix up the well built boxes.

Even so we all tend to over-value our second hand stuff and that monetary figure was if the boxes were damaged beyond a cosmetic repair.

One thing to consider is if the boxes are damaged beyond cosmetic, whether or not that may have also damaged the drivers due to possible G force ecountered...

thanks for all the replies and advice. I look forward to reading even more.

I am really amazed at the complexity of the choices and find it almost inconceivable that one could ever make the "right" choice. It is hard enough to figure out the right pair of speakers to buy. When you open up the diy option the options go through the roof.

I like the link to the cool preplanned designs, and I don't mind spending a lot more than $400 on parts, but don't really know how to figure out if i had a $1500 budget, say, what to build since I can't listen to any of these speakers before building them.

My original idea was either large bookshelves (supplemented by a smallish sub) or small floor standers - something with high WAF, but obviously I don't want to spend $1500 on speakers and end up with something that doesn't sound nearly as good as what you'd get from say Paradigm at that price (I currently have some 10 year old Studio 60's that sound pretty good to me, but it would be fun to build something that I made, sounded comparable, and looked better than the generic black boxes.)

Also thanks for the tip about hardwood, i do know that most people say not to use hardwood (although a few on here disagree), but even this seems to be something people can't agree on - a book I bought suggests MDF as the best, others on here claim it is not as good as good as good ply, so even there it seems hard to find an answer without trying lots of options first and I don't want to build 10 pairs to find the one I love (well, I'd love to do it, but with small children, work, etc, I don't have time for lots of failed attempts).

Small stand mounts with small powered subs do seem to have much greater WAF, and is a reasonable compromise.
As for box materials; there are "Quite" a few threads on the subject. MDF is cheap, chipboard is cheaper. I have had reasonable success with combinations but not with chipboard glued to thin ( 7mm ) softwood ply.

Default standmounts

by the way I didn't initially mean to imply that the speakers would be on bookshelves by my use of "bookshelf speakers." I just thought that was the standard name for smaller speakers that don't stand on the floor. If I build small speakers they will be on stands of some form, so I guess I should have used standmounts instead.

Hi,

Paradigm Reference Studio/60 v.3 loudspeaker | Stereophile.com

To build something better than the above you better know your onions.
