Building bookshelf speakers

Hey guys, my grandparents want me to build 4 bookshelf speakers for them, currently I have been visiting madisound Im thinking about using
https://www.madisound.com/store/product_info.php?cPath=45_228_257&products_id=849
and
https://www.madisound.com/store/product_info.php?cPath=45_229_324&products_id=374

I would use their LEAP software so they would design the crossover for me.
My main question is,
Is the above plan good for causal listening and will have good quality in sound?(ive never heard of the speakers above but by what madisound gives I think they would be good)

If the project above isnt good, are their any suggestions? like good designs for bookshelf speakers.

Their budget isnt a big factor on this, but try not suggest to expensive things.

Thanks everyone!:T

Picking a couple of cool looking drivers and then trying to design a good sounding Xover is probably not the way to go about this. How about if we start with some basics such as how much cash are you going to spend, how big of a box can they handle, what amp do they have etc. etc. etc...

I'm not liking the matchup very well. For that woofer I much prefer. https://www.madisound.com/store/product_info.php?products_id=8645

The breakup mode around 2khz in the other tweeter is going to cause issues. Since the woofer has issues at 2.5khz and up. I'm not a big fan of the woofer to be honest. You will need a tweeter that can be crossed at 2khz preferably 1.5khz based on the spike. Any other options for woofers or tweeters?

Thanks for the replies guys,
https://www.madisound.com/store/prod...oducts_id=8503 this would be good as well as it is in the budget, I may choose these unless their is a better option. thanks :D
box's are mostly limited by around 8"depth

They are going to buy a new reciever so I can help them with that.

Isiberian those tweeters are good too, ya i forgot to look at the graph responses since i was at school and now I see why I shouldnt have paired those.

The main reason why im thinking about making my own is because I wanna see how good the LEAP software they use is. But already built designs are good too.

Designing a crossover takes time, but if you can measure the drivers its not as difficult as it sounds. I use the Passive Crossover Designer spreadsheet. You really want drivers that have a lot of crossover range. Watch out for the rising impedance curve on the tweeter. You want to cross above that .

Internet has no shortage of awesome bookshelf designs IMO.

Here's a low-budget big-results one:

However it would require a decent subwoofer (maybe an SDX-10 or Trio12)

Here's another:

Here's another one that can probably be run full range at moderate volumes, but it does get more expensive as these are some awesome drivers:

Here's a madisound kit you should consider:

Thanks Isiberian for the suggestions, do you know where to get Passive Crossover Designer? Crossovers have always been a scary thing for me.

GranteedEV thanks for those great suggestions, and Im not to worried about the subwoofers since I have 3 Audiopulse epics that I am going to give them.
