Opinion on Dayton Audio RS722 value and x-over design?

[ubel]

Link to kit here
It uses one RS28A tweeter and two RS180S 7" woofers

It looks like a good value and I'm pretty close to ordering it ..

Both drivers reviewed well by Zaph|Audio however I know the tweeter has twin high peaks, can anyone here comment on the crossover design?

I'm also interested in the Zaph Audio ZA5.3 MTMs but I liked the Dayton Audio RS722s because they have larger drivers and cabinets .. can anyone help advise me here? They're both very close in price.

I appreciate any input greatly,
thank you.

RS series drivers are pretty good if well executed in the system. They need to be crossed over pretty low to keep away from their resonance issues. Without doing a full model, the crossover looks suspicious. A fourth order electrical on the tweeter? Metal drivers do like steep crossovers, so they may very well know what they are doing. No filters to deal with any peaks or dips but without measuring it in the box, no clue if any are needed. The 160's were not that easy to use. No idea how it sounds. Could be great. Understand speaker design is not about the sum of the parts, it is all about what you do with them. So it could be terrible. Let us know.

They claim everything including the crossover and cabinet were designed by Dayton Audio in the US .. I'd assume they'd want to back up their own products with a good crossover design.
But again, I don't know if it's a good design or not.

I'm tempted to go with the Zaph Audio ZA5.3 MTM because I know it's a professional and tried and true tested design .. the only reason I'm tempted to go with the Dayton's over the Zaphs is because the Daytons have larger drivers and cabs .. someone talk me into something lol.

rgds, sreten.

Similar to the sort of things Jon March does at Htguide, high order low c/o point stuff.

Thank you very much for that info. I had heard it was based off the design for the Dr. K MTM but I didn't realize it was pretty much exactly the same thing, including the crossover design.

Here's indepth info on the crossover design.

So get off the forum and buy them!

Yeah, I think that has convinced me lol. It definitely seems like he knew what he was doing when he designed them and hearing his comments on the crossover design have sold me.

Sadly they only have maple finish in stock ... I'll probably end up getting them because I don't want to wait any longer hehe.

Much more elegant crossover. You'll have to build/buy cabs on your own.

Thanks for the suggestion, however I already ordered the RS722 kit.
There is however quite a few and better crossover designs for them here and I believe in time I will upgrade to one of them, probably the Natalie design.

Thanks for the input

Hi, I have to agree. A fine example of minimal / optimal c/o design, rgds, sreten.

Less is more usually, unless its not enough, seriously applies to crossovers.
The above is the one worth trying as an alternative IMO, and the cheapest.
You already have 2 of the inductors, so 3 capacitors and one inductor needed.
