are you experienced?

Hello, my name is John. Since my Deutch is not so well I'm writing this in english. Allthough I can read your language well, my writing is 'to dutch' to you, so to speak.

I need some usefull clues to make a good configuration with the following loudspeakerunits: W300 NG, W200S,
DSM 50 FFL and DTW 97.

I recently bought a pair off homemade speakers with these units. The W 300 NG has a transmissionline, but I don't think the builder actually knew what he was trying to build. Sounds poor. He used a HW 4/200 cross-over and just 'hooked up' the units and didn't bother about fase and dB-correction. Results: harsh sound, 'gaps' in the overall frequencyrespons (you don't need equipment to 'measure' that; it's all to obvious by just listening). I bought these huge pair of 'refridgerators' (40X40X155cm) because they are nicely finished, cheap, but most of all: I'm sure it's possible to make an 'extreme make-over into beauty' because I'm convinced of the quality of each separate unit.
What I especially need is information about 'the best way' to make a cross-over for these units. With my building-experience I have learned that with frequently used units, like these, there is some kind of 'golden' match.

I'm looking forward to your 'tips & tricks'!

Hoi John,

Probeer het programma BoxSim eens (www.boxsim.de). Het wordt veel gebruikt hier op het forum en je kan er alles mee simuleren om een goede makeover van je boxen te maken

Das Flemische kann ich immer noch ein wenig verstehen, stellte ich gerade fest. (1,5 Jahre in Antwerpen haben doch Spuren hinterlassen...)

W200S + G50FFL (+ DTW 97) sind doch eh nicht schlecht.
Das ganze in 30l Bassreflex, den Rest mit Boxsim simulieren und fertig.

Dazu muss man wissen, dass man statt der DTW 97 auch die in der Datenbank vorhandene DT 94 nehmen kann. Die Frequenzgänge sind so gut wie identisch.

Dank voor alle reacties!

Mooi programma dat Boxim trouwens.

Groet, John

Do I understand you correctly, that you want to use the enclosure and just want to change the crossover?

with the W200S, the DSM50 and the DTW97 you could build a really good loudspeaker.
I think the W300NG can't come up with the rest, sorry!

what volume works the W200S on?
is there a possibility to modify the volumes?

Hello Che,

The w200s has his own sealed enclosure of 30 litres. It is possible to make it (much) larger within the total enclosure. But I discovered that this way the W200S nicely and naturally 'drops down' below about 100Hz . I am well aware the W300NG doesn't have the quality the other units have. But I love a bass that goes al the way down. So I came up with the following idea/ experiment:
I have a DT 150 (Detonation) subwoofer-amplifier with plenty of power and 'tuning' possibility. The W300NG's will get there own sealed enclosures (still within the original total enclosure) of about 90 litres (Qtc= 0.7). I don't have the illusion these woofers are suited for a vented enclosure since the are simply not 'stiff' enough. (And yes, that means 2X mono, but below the 100Hz you can't locate stereo anyway).

I will give it a try, but if the experiment fails I will have to 'switch over' to another plan...any suggestions?

Thanx!

John

That sounds good!

I think with a proper comibination of enclosure-highpass of the W200S plus aktive filters (and/or a passive HP for the W200S?) that will be a good sounding set up with a good "punch"! ;-)
