Number 9 Posted June 23, 2004 Share Posted June 23, 2004 I've done the rope caulk thing on the Forte drivers. Before I put them back in, I'm wondering if its worth doing some additional internal damping. As it is - "stock" - there is one piece of foam approx. 1/2" thick x 15" wide wrapped around the upper portion of the internal cabinet. No foam at the bottom near the woofer, nor at the back or front of the cabinet. Is this good enough? Quote Link to comment Share on other sites More sharing options...
busterfree Posted June 25, 2004 Share Posted June 25, 2004 It is good enough if you are satified with the sound. If you are not satisfied with the sound, what area needs improvement? Have you tried different placement options? Source equipment? Cables? Crossover modifications? This is something to think about. I too have the Forte II, and I thought about changing this and that. In the end, I decided to leave well enough alone and enjoy the music and movies. (I did upgrade my crossovers.) Good luck Quote Link to comment Share on other sites More sharing options...
Number 9 Posted June 25, 2004 Author Share Posted June 25, 2004 Well ... they are opened up now, so that's the thing. I can deal with everything else later. I have changed the caps in the xover. Quote Link to comment Share on other sites More sharing options...
dougdrake Posted June 25, 2004 Share Posted June 25, 2004 Does not the foam act to increase the interior volume of the cabinet, like "stuffing" does in car sub boxes, or does it actually provide a damping effect? Quote Link to comment Share on other sites More sharing options...
Number 9 Posted June 25, 2004 Author Share Posted June 25, 2004 Interesting question. By my understanding, if the mid and tweet produced a backwave, open cell foam can provide rear damping at those frequencies. However, as you know, in the Forte, the mid and tweet are horns, so it can't be for that. As for the bass, the open cell foam has little damping effect at lower frequencies (by my understanding). So I'm not sure what was the desired objective with the original foam in the enclosures. I've read all kinds of stuff, from lining the cabinets with Asphalt tile to lead. These would certainly help in making the cabinet "deader" in regards to parasitic resonances. Quote Link to comment Share on other sites More sharing options...
