Brother, looking at your room, I think I would try them on them left side long wall. I surely wouldn't want to be blocking exterior doors with my audio gear. Plus that front left is too close to the side wall. Using the long wall will give the speakers more room to breathe. I use the long wall in my own home.

Yeah that's kinda where I fall on it. I have been considering upgrading the jumpers on my CWIVs though. What do you think about that?

I haven't. Are they worthwhile? These are an upgrade cable made by REL? I'm normally not a big cable guy.

I've never heard a horn loaded sub in a home audio setting, but I do know this pair of REL T9/x subs has been absolutely transformative to my Cornwalls. And yes, the high level connection was the way to go, even though REL recommends low level for Klipsch Heritage. Output seemed higher and just faster using the high level connection no doubt. Mine are wired in stereo though. I wonder if it would be the same using one sub wired the same way they tell you to wire one sub. Using them in stereo, they recommend you twist the red/yellow wires together and attach them to the same red speaker tap. This is the only scenario where they recommend this.

REL specifically mentions corner loading the subs and placing them behind your mains. I initially had them right beside my mains with the drivers perfectly aligned with my Cornwalls but once I moved them back to the corners I knew I'd done the right thing. REL also specifically mentions forgetting everything you've ever heard about setting up a subwoofer when setting up the T9/x. I had a hard time doing that but I'm glad I finally listened to the literature because this configuration sounds best to my ears.

My findings were exactly the same. REL specifically states to use low level input (RCA) for high sensitivity speakers and they mention Klipsch Hertiage by name. I wasn't happy with the output using it though. I switched both subs over to high level and immediately needed to turn the gain down. My crossover is set at roughly 45hz and the gain is a few clicks past 12:00. Just a little past halfway. Honestly though I could probably stand to turn it down a few clicks but I'm still enjoying the new subs a little too much right now and don't mind the bass being a bit exaggerated.

This thread really devolved into a shitshow, but I don't care cause I just added a pair of T9/x subs to my Cornwall IVs and it's incredible. I tried both input methods and decided I got more output with high level and just better speed.

Sorry I missed this, I don't check in on the Klipsch forums as much as I used to. Probably something to do with the fact that I haven't purchased audio gear since November 2021, just been so content with my CWIV and Audiolab 6000a Play combo. I mentioned this in another thread, but I believe I was one of the first, if not the first, people to recommend you getting into a Klipsch Heritage speaker. It's cool to see that you've gone and picked up another pair! Though if I remember correctly, you live in a pretty small apartment, has that changed? A lot of people recommend subs with the Heresy line. But I would absolutely try placing them closer to the wall just to see. I actually use two subs with my CWIV if the mood strikes me. I've got two cheapo Klipsch subs hooked up to the pre-outs of the Audiolab and crossed over at 40hz, so they just pick up where the CWs fall off. I enjoy them with the subs too, but they lose their speed and precision with the subs enabled. I'm very much interested in a pair of Klipschs new subs, either a pair of 10s or 12s, but due to their massive size, it would damn near require a rearrange of my entire front stage lol.

Hey I know you from Steve Hoffman Forums! I believe I was the first guy to recommend the Klipcsh Heritage line in your thread for your search for new speakers! Welcome!

As far as the original topic, in regard to getting more bass out of a Cornwall IV, the answer is simple: get them as close to your front wall as possible. The inside corner on my CWIV is 2" from the front wall, the outside corner, because of a fairly aggressive toe-in, is 17.5" from the front wall. I would urge anyone wanting more bass out of their CWIV to try a similar positioning. Most people I See with Cornwalls seem to neglect the "wall" aspect of the "Cornwall" name. These speakers are literally not designed to be pulled out 3-5' into the room like your average speaker. That is, unless you love shouty mids that overpower every other band in the FR.

Jesus they are literally so huge though lol. Even the 10" RP would be a massive upgrade from my pair of Best Buy special 12SW subs, but even the 10" RP is 25" DEEP! But I would have to push my speakers closer together to be able to align the front of the sub even with the cabinet of the Cornwalls, being positioned on the outside of each speaker, which is how I like my subs positioned. The 10" is rated down to just below 20hz, which is incredible! Also a good bit cheaper than the 10" REL T/9x I was considering a year ago.

I'm considering a pair of these new 12" subs to go with my Cornwall IVs....that 5-year warranty basically eliminates any worry I had about reliability.

That Denon is no slouch. The money would likely be better spent on an extra sub.

Give a man a record, he can listen to it till it wears out. Give a man a bowl made from a record, and he can eat cereal for the rest of his days.

I tend to use db-C, with the mic right in front of my forehead facing the front of the room/in-between the speakers.
