Dayton Woofer Comparison

[Wyloch]

I am building a set of Dayton IIIs using this plan:

The plan uses these woofers.

I would like to instead use these woofers.

Can I simply make the substitution without having to modify the crossover circuit given in the plans?

Obviously quite a newb here...

The short answer would be a big no.

Every crossover and driver combo is unique and you cant just switch the one or the other. As you're obviously not an experienced crossover designer I recommend you pick a design that pleases you as it is. There are some many available that you should easily find something that suits your needs.

Hi,

I'll second that, Absolutely NO.

I am upgrading the drivers some bookshelf speakers. They were Sony ss-u3033's. They are sealed boxes measuring 13"H x 9"W x 7.5"D.

I'm trying to do this inexpensively with minimal box modification. I've narrowed it down to 2 mid - drivers. The ones mentioned earlier. The 7"Dayton Aluminum or the 6.5" Dayton Classic.

I will be probably using an Audax tweeter:

I will be making a simple 1st order crossover for about 2000hz.

With this plan, I won't have to modify the box at all.

Which is the better driver for this sealed application? Classic or Aluminum?

Thanks.

Hi,

you should use one of the many 6.5"/1" designs available.

Searching further, it seems that the Dayton Classic would be better for this application.

- 3db more effecient
- not as much x-max as the Dayton aluminum, but the classic is more controlled up to 2000 hz

I also found a project using the Classic and the Audax tweeter I'm considering.

PartsExpress has two kits similar to what you're looking for:

Look at #302-930 and #302-940 -

The first uses the smaller 5.25" aluminum woofers with the silk dome tweeter; the second uses the larger woofers you want but with a different tweeter.

The assembly manuals for the kits can be seen on the "Manual" tab - you'll need Adobe Acrobat Reader (free). The crossover parts, schematics and instructions are clearly laid out.

So you can probably get away with purchasing all the parts separately and substituting the 7" aluminum woofers for the 5.25s, using the larger cabinets. I haven't compared the crossovers for the two kits, but you can check the woofer networks of the two to see if there are any differences, and perhaps extrapolate from there.

Of course if you feel you could live with the smaller woofers you could just buy the 5.25 kit - recommended for a newbie! Depending on your room, preferences etc. a subwoofer to round out the bottom end should be considered.

Wow! Thanks for all the replies! I'm gonna spend a few days here and sift through all of this.

Thanks again!
