3-Way Bookshelf miniDSP Attempt... Will this work?

[vokus]

I want to build my first speaker.

A 3 way book shelf, with minidsp for crossover and a dedicated amp for each driver.

Would these 3 drivers be reasonable to use together?

HI: Dayton Audio RS28F-4 1/8" Silk Dome 4" Tweeter
MID: Dayton Audio RS150-4 6" Woofer
LOW: Dayton Audio RSS210HF-4 8" Sub

I am thinking going sealed boxes. I want a book shelf with a little bit more umph on the low end. A little bit more then this.

Is this a good idea?

Any other driver recommendations?

Thanks for your time and advice!!!

I didn't know Bic was still in existence. I would want to go with larger baffles for a 3-way speaker. And use the 8" with domes for 2-way sealed bookshelves. Look at some snell and audio note's from yesterday and today 8"/dome's are a proven design. So are some of the sealed 8" 3ways in larger cabs. http://www.snell.no/the_archives.htm

I would use RS100P-8 for mid and RS225P-8 (or RS180P-8) for woofer. If adding a sub make it cross below 80Hz.

Paper cones have closet character of sound to silk dome. That's an excellent tweeter choice.

I made a 2 way with RS225 and full range mid/tweet here. I did try RS100P but it lacked sparkle as a tweet but would be perfect for a mid range.

Sealed is good as you get tight bass with low group delay. You can use Linkwitz transform to get deeper bass.

For RS225-8 sealed 24L I can get about 45Hz F3 with no EQ.

Here is latest with passive xo and SS 10F/8424 mid tweet:

Thank you SS4927!

That Bic Formula FH-65B sounds really nice with the horn loaded tweeter, and I had it for a long time. I just want a lot more low end with out going to a standalone sub.

Thank you xrk971!

Your tread is a wealth of information, will be reading thru it.

So now I am thinking of a 4way sealed bookshelf speaker.

xrk971 What do you think about this?

RS28F-4 1-1/8" Silk Dome Tweeter 4 Ohm
RS100P-8 4" Reference Paper Midwoofer 8 Ohm
RS180P-8 7" Reference Paper Woofer 8 Ohm
RSS210HF-4 8" Reference HF Subwoofer 4 Ohm

If making a sub go with 12in driver. Looks good though. What amps are you planning on using?

Can you give me a few pointers on why its better to use 12 inch subwoofer in a 4 way design instead of a 10 inch subwoofer or an 8 inch subwoofer? Is a 12 subwoofer driver the ideal size to performance ratio?

---------------------------------------------------------

I am not sure about the amps, and I need suggestions. I was looking at a few different cheap sure amps, but I am not sure about thier audio quality, because I don't know enough about these T-AMPs. I found these, but they are kind of on the expensive side.

Monoprice Monolith 7x200

Emotiva A-700 7x110

With sub woofers bigger is always better. It's about air displacement and nothing beats more cone area. An 8in driver unless in a horn enclosure won't really make much SPL to be qualified as a real sub woofer to keep up with the sound level from the 3 way tops. A pair of 12in drivers is sort of minimal area for a sub. Use Dayton's RSS series in 12in. It's very nice from what I have heard. Put in a sealed box with a big amp and Linkwitz transform.

Thanks!

Is it ok to use the 4 ohm versions of the speakers you suggested earlier for the mid and midbass?

How does this look?
