Leok, I'm curious as to what caps you used and the effect it had. I have the Forte'speakers which have different crossover points (HF is 6000Hz vs 7000Hz and MF is 700Hz vs 650Hz). Did your changing out the caps make much difference? If so, how might I figure out what caps to use?

The components on the different one appear closer to what I've seen on Forte-II (and Chorus-II for that matter). The cap changes are the Solen metalized polypropylene film to replace what were probably mylar. For the trouble, I would have (and have) used even better substitutions: Hovland polyprop. film/foil. On my Chorus-II I went so far as using Jensen foil/paper-in-oil for the mid. I don't know why stock mylars would sound better. Dean doesn't like the Solens much (that might be understatement), but I like them ok. I would expect them to be better than mylar .. smoother, more natural sound and slightly better detail. leok ----------------

Aabernathy, are you still pleased with your x-over? I'm considering taking it on as a project but was curious as to your thoughts now that it has been a few years. Any idea what Al's new web site might be? It tried the www.web-span.com/alk/klipsch.html location and received a message saying the site didn't exist anymore. Thanks, -tim

Strabo, I pressed the rope caulk into the valleys of the ribs, over ribs into the next valley and so. It did make a big difference. The WAF approval factor was quite high on this one followed by putting in speaker spikes which was also what high on the WAF scale. I used 1.5 roles of rope caulk per for each Forte. Also I did not bother breaking it into small strips. It's like modeling clay and it takes some time to do but worth it.

Dougdrake's right on this one. I have a Yamaha DSP-A1 with the same setting options and the same "symptoms." Set the receiver for Both. Set your mains to Large. The surrounds including Center I've found sound better set to Small even though that doesn't match what the manual suggests. Set to Small the sub seems to come in sooner and "round out the sound" in the room if that makes any sense.

Okay, for those of us who can't choose Cardas or tube amps to solve the bright horns problem what are the other solid options. Other than gauge of wire being important for longer runs I'm having a hard time trying to figure this out definitively as the ideas are all over the place. Is there a It's a Terrible Idea list where people have tried things that worked terribly?

I took forte's advice, ordered the spikes and installed them. They do sound much better! The bass it tighter, the imaging clearer, the WAF is actually high on this one as she could tell the difference and very much approved, and the SPL increased across the board from 160 Hz on down. I had been moving the sub around the room so had taken the spikes off it for that and as a result had been doing a lot of SPL measurements and graphs. The graphs definelty show how spikes have increased the SPL of all frequiencies from 160 on down. It's really cool to see. Thanks to you all!! Now about that putty someone mentioned putting around the mid-range speaker...obviously another thread and a hobby that is never done. Thank guys

I found the spikes I think. It almost looks like you have 1/4" spikes but partsexpress.com shows 3/8" and 1/2" spikes. 3/8" just seems too big based on what I recall the thickness of the wood stand is. I'll have to go measure. I was considering building a base with threaded rod post sharpened than screwing the base to the bottom of the speaker itself. It's been one of those half finished projects since Iwas quite happy with the idea yet. Thanks the update tot he thread. I'm quite sure I'd rather go this way one I figure out the size spikes to use.

Yeah, I'm going to have to agree with you guys. I have tried it all weekend, I noticed the mid's-highs are liberated a bit, but the low's -highs are missing which comes across as not quite as full. I may try it again at some point and run a frequiency analysis just to prove it. The integrated amp I have sends either 110 or 130 watts per channel to the mains. I enjoyed having those mid-highs but am puzzled how to get those back without a seperate amp.

I see reference to "braided cat 5" speaker cable. Is this truly the cat-5 stuff we run for computer networking? -tim

In the new Digital Video Essentials they recommend that even with large full range speakers that the receiver be set to the "small speaker" setting, letting the sub handle all the bass. For grins I'm trying it and have found immediatly that I need to rebalance and measure everything before I can make a good comparsion. Unfortunitly I loaned my SPL meter to a friend who has not returned it as yet. Anyone else tried this suggestion and if so what was your experience? -tim

That's a great thread. Thanks. On the electronic stuff, what are the sound differences you noticed pre/post mod? -tim

Rich, Did you ever do these mods? If so what did you think. In curious as to the before and after sounds. -tim ---------------- On 6/8/2001 5:20:00 PM Rich Carroll wrote: Drew et. al.-- I haven't posted for a while because of several things that have kept me away from the speaker mods and the computer.

I need some advice about how the Klipsch Fortes (the original not the II series) were designed by the engineers to be placed in a room. Basically, were they intended to sound best when place in the corners of a room or moved away from the corners and into the room several feet? Im trying to tune my room some and wanted to start first with the optimal location for the speakers based on the design intentions. In case you have additional thoughts on the location, what I am working with is my living room which is a 14 x 30 room with 9 ceilings. I am planning on putting the speakers on the 14 wall where I have a couple large 5 x 3 windows arranged roughly as: left corner to 1st window 3ft, a 3ft window, a 4ft center wall space, a 3ft window, followed by a 2ft wall space which ends in the corner with a 4inch piece of molding which is the start of a 4ft entrance into the foyer along the 30 wall. After placing the speakers in to optimal location based on the design specs, I plan on moving them around some based on getting the flattest frequency responses using ETF or other acoustic frequency generation/sampling software.

Anyone thought about adding spikes to their Forte's? I've read that subs need them for better bass reproduction and transmission and the Forte's are great at bass which got me to wondering if spikes might enhance their sound even further. Any thoughts? They are currently sitting on the their supplied base on a carpet.

Thank you so much for your assistance. I still consider these Klipsch some of the best speakers in the world. I love my Klipsch!
