Default Econowave with WAF ?

I quite like the thought of Econowave speakers, but i'd never get away with something that big in the house. My current speakers are 10" (250mm) wide x 11" (280mm) deep x 43" (1100mm) high and are just about acceptable to the girlfriend.

I was thinking of using the Emeninence Beta 8A with a side-firing Eminence Basslite CA2010. I dont like ported bass, so I was thinking of giving the Beta 8A the top 10 litres (QTC=0.707 f3=120Hz) of the box and the CA2010 53 litres (QTC=0.707 f3=70Hz). It looks like i'd have to make the box a bit deeper than my current speakers, but I think I should get away with it.

For the tweeter I was thinking of using the B&C DE250 with the RCF H100 horn.


I know they aren't going to produce really deep bass, but with room gain and the slower roll-off or the sealed box, I think the bass will be ok.

Any thoughts ?

Some say that women have that 6th sense
It may be translated also to sound reproduction.
They don't want tech talk and obsession , just good sound .
And often , they do like shoe-box cabinets , but that goes against phisycs' laws.
One month ago a woman came to my house ( a friend of my parents ) and , as I've just finished my analogical setup , I made her sit and I put on the turntable a collection of the Rolling Stones . She was so happy ! She never listened to them so good , she said . I believe , I could imagine the sardonic smile of Mike while he's singing . That 's what a sound reproduction system should do : transmit emotions .

I think that you should re-consider the thing : a good hi-fi speaker would do the job much better than the drivers you have considered . Efficiency nowadays isn't an issue ( for amplifiers ) . I've bought some months ago the tiniest compression driver that B&C produces ( BTW they are in my town , Florence ...) , the DE 7 but in a little room like mine they can't really produce the sound they are supposed to.

All good drivers, though apparently the RCF H100 is not a true constant directivity horn.

These would be better plus they are optimised for the DE250: Fiberglass SEOS-8? - SEOS? Products - Waveguides DIY Sound Group.

Or wait for the cheaper plastic version coming soon if they are over your budget....

I use the above combo to good effect, the RCF horn matches the DE250 really well. There is minimal compensation. I think you would be very happy with this combo.

#1 Can't a compromise be made with your gal? I mean crikey we're only talking 1.5-2 cubic feet per cab.. Too many women these days are ruling the nest with the notion that stupid little ipod dock players are to be the maximum for real estate in the home decor department..

#2 Build the deluxe version of the Econowave and maybe she'll appreciate the great sound that by most all accounts is quite stellar..

#3 This waveguide is the better option in the Deluxe EW with the B&C250 from what I've read that's been all worked out by Zilch and Company:
QSC PL-000446GP Replacement Waveguide Horn for HPR152i 245-625

Cheers

That is a slight concern of mine. My current speakers have doped paper cones and sound very vivid and lively. I wouldn't want my new speakers to be too raw or vivid sounding, but if I had to make a choice, i'd prefer that over a too smooth or dull sound.

Looks like a nice horn, but I couldn't find any for sale in the UK and they are pretty expensive.

Glad to hear it works well with the DE250. It's not too expensive either.

Active has never interested me. I like to keep things simple (the girlfriend also hates boxes of electronics and wires) and as cheap as possible. I can see why going active is so popular though...
