Driver substitution

[Glowbug]

Hey -

I've found this design: http://www.humblehomemadehifi.com/The_Monitor.html that I like both aesthetically and because it apparently works with very minimal crossovers...that's good on my wallet and my 8w amplifiers.

Only problem is that I can't afford the $300+ Audio Technology C-Quenze drivers the original plans used. The Hiquphon tweets are no problem, but those mids would sink my budget by themselves.

I was wondering if anyone had suggestions for substitutions I could use in their place...I was thinking something like a Seas CA18RNX, because of its really smooth FR. Would that driver work to replace the Danish one?

Thanks

Hi,

Don't even think about it, build a design for the intended bass/mid.

There are better value drivers than both of those in that design.

Most 2-way designs can be converted into a floorstanding vented.

A rear PR adds significantly to the cost but is not much better than
using a properly flared port.

Thanks for the link, but my amp isn't four ohm stable

That's why I was looking at two-way designs, to stay @ 8 ohms nominal.

That'd be perfect for what I'd want, except for the impedance...he even says it works with his 300B amps, which is about the same power that I'm working with too.

Dayton Reference midbasses are 4 ohm, but I'm stuck substituting other woofers again.

Modern drivers tend to be designed with modern amplifiers in mind- they're not very sensitive. If you look back to when everyone used tubes, you see that speakers were a lot more sensitive, and there were a lot of horns. I just saw your signature's mention of Klipsch, so I see that this isn't news to you.

Lately there have been some professional drivers that would probably suit your needs. Have you checked out PI speakers? They have a number of hi-fi / pro kits that use Eminence pro drivers. I've used an Eminence driver at home before, and they're quite good. They're not shielded, but I believe that the neodymium pro drivers have self contained magnetic fields.

The Eminence Beta 10 CX was an old kit that Adire used to sell with a proprietary tweeter driver and custom crossover. I've recommended this before, and I think it should give you an easy to drive impedance and high sensitivity.
