Possible Summer Project

[bose301s]

Well, I would love to build a set of bookshelf speakers just for fun. I think I have the tweeter picked out, looks interesting and Zaph really liked it. It is the SB-Acoustics SB29RDC-C000-4 Ring Dome tweeter. It is a new take on the ring radiator from SB. The woofer is up in the air but the main candidate is the SB Acoustics SB17NRXC35-8 6" woofer. I am also considering the Exodus EX-6.5 Midwoofer and the CSS SDX7 Subduction 6.5" woofer. The prices on those are ~$50 more than the SB so I would prefer to use the SB, but if one of the other 2 are that much better I would probably be willing to switch. Any help is appreciated in this design and project.

According to Zaph, the 6" SB has really low distortion, and would be hard to beat. Might need a higher order xover though, the high end is a bit ragged.

This was a prime candidate for my next, I chose the Peerless 830883 only because I can use a smaller box.

Yea, that's why I wanted to use it, but for a 2 way that upper end break up is scaring me a bit. Does that Peerless have any better high end extension than the SB?

[PeteMcK]

in terms of extension, they're similar, it's just that the Peerless is a bit smoother
Zaph has tested them both

If I were to do it with the SB would a 2.2K @ 24dB/oct work?

Ok, I think I am going to eschew all of the choices I have posted up so far and go with the SEAS Prestige CA18RNX. I may have Madisound do the design for me, but if anyone has advice it is greatly appreciated.

Have a look at the newer version of this driver, Zaph's done all the hard work: http://www.zaphaudio.com/SR71.html

Driver choices are hard - now I find out that there are two versions of the 830833, and the local supplier is quoting the old specs... doesn't fill me with confidence

I'll probably hold off on my 2-way project for now, I've got plenty else to do with drivers I've already got (update my OBs, rebuild my cheap Jaycars, build some rears & sub for HT).

I say give the SB 6" a shot. A friend of mine built a 2-way using the 6" SB mated to the regular SB dome tweeter. Both the bass and midrange of that driver are impressive.

I know he had to use a 3rd order network on the woofer, but I don't think that should scare you away from it. Though your Seas choice would also be great and probably only need a 2nd order x-o.

Either way, please keep us posted. I know a lot of folks are interested in hearing experiences with that tweeter. Good luck and have fun.

This project is looking less and less likely to happen due to financial circumstances. I thought I would have enough money for it, but some on foreseen events are making it look like it may not happen, however if it does, I will keep everyone posted, for sure.
