Proac 2.5 Vs. Scan-Speak Event

grhamel · 16th January 2004, 10:20 PM

Hi,

I was looking at building the Proac 2.5 clone, but then the Scan-speak Event caught my eye.. The event is a 2 way TL based on the SS 18W/8535 and 2905/9300. Looks a lot like the Response 2.5 but the big difference is the TL design.

Using Martin King's worksheets and the enclosure dimensions listed I get an f3 of about 30Hz for the Event, which is niiice, but I can't find a published response curve for the end result, or any reviews whatsoever.

I'm wondering if anyone can offer any advice or reviews of this particular design? I like the TL approach in particular due to the non-resonant enclosure, and over the Proac in particular which has basically a square cross-section and much raging discussion over the xover.

Any and all comments appreciated,
Thx

I have the 2.5 clones and love them. The " raging discussion " of the crossover has been a real plus to the owners of these. Using the results you can voice the speakers to your own room, components , and taste. Better than the original designer that has to comprimise for best results in an "average" setting.

Regardless of which you build I VERY STRONGLY SUGGEST to place the crossover outside the box or in an otherwise reachable place to tweak the crossover to your liking.

I agree with the above. It may take some getting right but all the information about XO just provides more choices. Mind you it can drive you mad trying to get it perfect! The 2.5 is as good as any thing and above all else it is easy to build (as easy as it can be). Relatively good value, great sound, lots of help out there, easily changed to suit your tastes and elegant. What more can you want in a project? Well worth the effort – you won’t be disappointed.

don't be concerned over XOs versions- they're all very good! and really there's only 3 to choose from - the original from the geocities website, the V6 iterations if u want a more neutral sound (i find the raspy treble very exciting but harsh on some recordings), or like me, you want to use the 9500 tweeter (more versatile tweeter that could always be used for other projects)

i have Troel's 8535/9500 CO in a geocities cabinet- followed it's cabinet dimensions, port tuning, wall damping and dacron lining perfectly. No tweaks, and it sounds splendid. true the midrange isn't with best of the 3 way speakers, and although it's considered it's greatest weakness, it certainly isn't BAD or intolerable.

it still has the musicality, sweetness AND bass to shock non hi-fi buffs.

i placed the crossover internally, but right behind the drivers so that i may make minor changes (tweeter level) if necessary. in retrospect it wasn't necessary since it sounds great straight away!

stick with the correct damping and dacron and leave the guesswork for other things.

Hi grhamel

I have an orignal copy from Elektur Magazine "Hi-Fi-luidspekers 9"with FR and waterfall plots of the Event I can e-mail you as soon I get scanned files

You can also ask to Event designer Rolf Smulders on www.audiocomponents.nl, info@audiocomponents.nl

Hope it helps

Hello, If you scanned the articel from the Elektuur, I also would like to receive a copy. I have got the Event, but I don't have any measerements.

Regarding the Event I am very happy with them. I have made a slight adjustment at the crossover (got rid of the capacitor parallel to the woofer). This gives the higher mid a little more body.

Hi grhamel

The event is a 2 way TL based on the SS 18W/8535 and 2905/9300. Looks a lot like the Response 2.5 but the big difference is the TL design.

I´m playing with Mathcad Explorer8 and MJK worksheets in a enclosure similar to Event but with a Vifa PL18 woofer. My questions are:

What WS are you using, Mass-loaded, Off-set?

From Event enclosure drawing what line lenght and driver ratio did you figure to plug in the worksheet?

How did you plug stuffing values?

TIA,

JC
