In an effort to stimulate the economy, I bought a pair of Klipsch Cornwall IVs. I was stoked to receive them, but upon hooking them up to my system, I was shocked by what seems like completely absent mid-lows / lows. I’ve been fiddling with all parts of my system, but without much success. Looking for advice on what else to try before I send these back.
Setup in order:
2’ basic USB cable
Denafrips Aries II
20” iFi RCA. I’ve got custom built RCA 20’ RCA replacement arriving next week.
Prima Luna Dialogue Premium Integrated w/ “Tung-Sol” KT120s, well warmed-up. 40+ Watts / channel should be plenty on what are often referred to as “easy to drive” speakers.
10’ generic 16 gauge speaker wire w/ bare wire connections. I’ve got a pair of Canare 4s8 with spades for amp and bananas for speaker arriving next week.
15’ x 19’ furnished living room
What I’ve tried so far:
AA battery test for speaker polarity. Speaker polarity is fine.
4 ohm and 8 ohm speaker connections on the amp. Bass absent with both.
All the speaker placements. Listening position is 13’ from the wall by speakers, speakers are 10’ apart center-on-center:
Against the wall flat.
Against the wall toed in slightly.
10” off the wall flat.
10” off the wall slightly toed in.
3’ off the wall flat.
3’ off the wall, toed in with all the angles, including where their center lines cross 3’ in front of listening position.
Reversing phase on one of the speakers. This results in some of the bass (still nowhere near what’s expected) appearing, but imaging is completely gone. I’m just hearing music from each speaker with a really crappy sound stage. Can’t place instruments or vocals.
Reversing phase for one channel in Roon DSP. This was a great way to A/B test phase reversal by switching back and forth to make sure I know what I’m hearing re: sound stage and bass.
Reversing phase on both speakers.
Reversing phase on one speaker.
Tidal MQA source material; both scaled up, and not scaled up.
Tidal 44kHz/16bit FLAC; both scaled up, and not scaled up.
Parametric EQ. I can make things sound different, but bass is still absent.
Listening to them standing up, sitting down, walking around the room, and jumping up and down in frustration.
I have a flickering hope that the 13 gauge -equivalent Canare speaker cables will make a difference, but I have a hard time believing they would correct such a glaring lack of mid-lows and lows. I’m not about to play the lottery with swapping out the crossovers or reinforcing the internal bracing — I’m ok with tinkering, but oh man, I’m expecting prettier music from a $6k pair of speakers out of the factory.
I feel like I made a mistake buying these without hearing them in person. I live in SF, and for some strange reason Klipsch doesn’t have dealers who carry the heritage line anywhere within a 2 hour radius of this major market. I relied on Steve Gutenberg and other reviewers who explicitly said the bass is there, and plentiful.
The sales guy I ordered these from said they’d be a good match for my system, and to burn them in for 200 hours. 200 hours is ridiculous — how is anyone supposed to play 200 hours of music before the return period expires? Now, sure, maybe the sound will change over the initial 200 hours, but I don’t believe it will change that much.
Anyways, any advice would be appreciated.
