Default Scan speak floorstander with 2 woofers

Commericial examples of these include North Creek Rhythm, reference plus, etc.

Basically a ProAc 2.5 with another woofer added.

Are there any of these DIY projects out there?

Hi IIRC
SOLEN may havea design on their site using 2 off 8530 revelator woofers + ring tweeter
Probably rather nics albeit pricey design.

pricey indeed

the audiocomponents reference one is also abit too far fetched with the sloped baffle. Cabinet costs would escalate.

Default thinking abt it.....

If I were to add another woofer to the ProAc 2.5 clone, is it just a simple case of doubling enclosure size if I leave the tuning freq alone?


Or will it inevitably need a Xover redesign?

The XO is online. It's always the last drawing

Actually they have crossovers right there, at least for the Reference Plus (the one with dual woofers like you said you wanted).

Here's the page that features other links with mechanical drawings etc.

EDIT: Whoops, Bricolo beat me. Do I get points for thoroughness anyway?

eh thanks.

altho I realise now they use the revelator 9900 tweeter. and the cabinet expense tops it off.

Does anyone know of designs that are more easier to build? (and easier on my wallet)

thinking along the lines of a ProAc 2.5 + second identical woofer.

possible without a Xover overhaul?

Not a floor stander, but I built Scan Speak Solists from Madisound and was very happy with them. I sold them to my son when I got into horns

http://www.madisound.com/solist.html

Put a pair of subs that will integrate well with them.
