Hi, I know this is 7 months old, just wondering if amp is still for sale? Thanks, Ted

Here we have a situation where you have not responded to my inquiry as to another source just to try. Now what we are doing is continuing troubleshooting. Regardless as to the quality of the music, we want to bypass the Dac entirely, just to see if the bass is being impaired. Just a methodical approach to suss out what appears to be the bass. Look at your connections to the Dac.
The cable I suggest will give full bass if there is some setting inside the computers sound card....Ask again, what is the model of the Emotiva... thanks
Got it, I will bypass dac as an experiment, yes. Emotiva BasX150

Now that we got you, do the @dtel ...recc on the computer.
link/info above.
Then, try, if you have the output from computer laptop(?) audio out bypass the Dac and go straight to the Emotiva using a 3.5 mm to RCA stereo cable to a line level input to check out bass performance.
Thanks!
I’ve always used usb from laptop to Dac, then EQ, pre amp, lastly Emotiva amp.
using Spotify premium, can’t remember the specs, not as good as tidal, but good.
Wouldn’t using 3.5mm jack on laptop mean using the worst possible dac, the one in the laptop? I could try as a test, but it’s a bad way to connect.
it seems like room acoustics, which I do not understand, standing waves, nulls, etc. I definitely change the bass by moving into corner, out from wall, corners give most bass, which is what I consistently read.
Anybody think absorbers or diffusers close to speakers help? Can’t imagine that would increase the bass, I think just change the character of it?-

this is the amp -----
That looks like mine. 75 wpc. It sound more solid and tight than my schiit Aegir, which sounds mushy on the CW’s

So perhaps the next question would be REL or SVS ?

One thing I noticed after downloading a dB meter for my phone is that my usual listening levels are 60-70db . Louder than this the bass certainly becomes very prominent. Are others getting good bass at 65db or is this the problem

My cornwalls have very prominent bass. So something may not be right with your setup or room. it may also be that nothing at all is wrong and your other speakers just had more bass.

Are you able to take any frequency response measurements? You would be able to spot the issue pretty quickly that way.
No, don’t have test equipment

All same amplification as with my old Klipsch RP6000f . If i added 12bd with EQ on those towers it was a boomy, muddy bass, bad, and to much of it. So I think amplification is ok. Elacs still put out bass today. The Cornwalls are definetly a more laid back, less punchy base. While inside I disconnected mid driver and the total volume dropped A LOT! Tweeter was super quiet, the mid seems to be supplying 80%+ in terms of total sound. Does that seem right? Also wire to woofer appears to be aluminum, maybe aluminum coated copper, but definetly not 100% copper, is that normal?

No, do think crossover is fine. You can expect a prominent mid sound.
When the bass is correct, it will sound alright. This for now...
I have a straight up power amp, no controls. Pre amp is volume and input selector, and separate EQ. Hardly any settings to mess with. Switching polarity was negligible in difference, I probably don’t have very sensitive ears...
I just don’t see anything like people saying “tons of bass”. It’s so confusing. They sound great otherwise, I did not think I would need a sub, but....

@VDS ...try what the member proposes here. Time to methodically double check the above.
Think, what has changed if anything on your Emotiva since removing your Elacs. Hook one Elac back up to the Emotiva to test bass with your setup.
That’s a good idea, when was listening With the back off it seems like a lot of bass is being produced, it seems like the midrange is so prominent though that it overpowers the base, would a crossover adjustment be needed. But I’m sure Crites had made a ton of B3 crossovers so you would think that would have come up

And are you using a separate EQ equalizer?
Yes, 4 frequency Schiit Loki, 20hz at 12db gain, 400hz at 2db.
location does make a big difference, I’m finding that. But haven’t found a location that give me too much bass-

Newer Emotiva power amp, 75 wpc, schitt Saga preamp. schiit dac from laptop, exact set up with Elac speakers that made a lot of base for a 6" bookshelf woofer

You may have but, I would trace the pair from crossover to woofer to make certain correct. If you have not reversed the polarity of one woofer would do so to double-check. You will know quicky if you were correct. What woofer do you have. Should find numbers on the magnet area.
I checked, but I could switch and see what happens

I've read every thread I can find about Cornwalls that aren't producing bass. I've checked all driver leads inside and speaker leads, all seem correct for polarity(?) I've moved them around room and i can only get base by boosting the full 12 db through EQ, even then its not overwhelming. I've had other speakers in same room, same location without bass problems.
New Crites Crossovers in approx 2004 (B-3) could something in crossover have gone bad? 75 wpc class A/B Emotiva amp.Im only 2 channel stereo, no home theater, not looking for gut thumping, but the bass really seems light, EQ all the way up makes it ok , never overbearing.

Guys, Let me point out that we have not yet heard about what the specific problem is that needs to be cured.
Is it a horn issue, is it a dispersion issue, is it a crossover issue , is it a driver issue, etc. I afraid this might be a case of "lets just change something and call it an "upgrade". I won't even touch the concept of "let's measure before and after"
Good luck,
-Tom
I’m just hoping with the long history of Cornwall, and the experience of this group, they are some accepted mods that are generally considered upgrades by most listeners.

great horn -------or even better , buy a K401 from Klipsch for 100$ and place it at the top of the cab with no need to drill any holes -
Can you seriously buy them from Klipsch still?

it's called a Cornscala
Yeah, Ive looked at Crites horn, as i understand is a JBL 2380 clone, 2'' throat. Read mixed reviews of the JbL, some love it, others dont. but it does seem most Cornscala owners are happy... Ive looked at what Volti is building for their updated LaScala, which looks similar to 2380.
-
Hi, I’ve read a lot of the threads that talk about horns, but still not enlightened, certainly horn design is a complex endeavor, but is there any consensus on installing a larger mid horn on Cornwalls. Everybody raves about the mids on LaScala and K Horns, both with large horns. I am exploring replacing stock horn with, I think, something larger. Even if I have to cut a hole in the back and have driver outside of cabinet. Like PWK said “music lives in the midrange” And I want as much as possible.
thanks so much for any perspectives on this. Using A55g drivers.

NO , the kappa 15C is not the best woofer for BASS you have to read the link I posted here , the -Eminence Neodymium Series IS THE BEST -Claude worked on this concept for quite a while and his Super Cornwall is a Cornwall 1 with more BASS which is exactly what you want to do -
and yes , you have to buy an 4Ohms woofer , all Cornwall woofers are 4Ohms ----------8Ohms will not do -------your current woofer K33 is a 4Ohms Woofer -------be careful with this or you will have problems --
I will read the link...thanks for the 4 ohm info! I’ll let you know if I have questions after reading tonight

you can go with Claude's new woofer , the 15 inch 4 ohms -----Eminence Neodymium Series
If I did make a woofer change, I was thinking Eminance Kappa pro 15A, 101 dB, 46 htz. 8 ohms. Is 4 ohm compatible? In kind of fuzzy on impedance

If you are a bass freak, like a longtime friend of mine, you can just re-solder the midrange from #3 to #2 on the T2A Autoformer and go to a 2 uF capacitor value, assuming you have a "B" network. This will drop the midrange by 3 db, and leave the woofer and tweeter alone. Your ROOM and your EARS will decide if this fully reverse-able mod is right for YOU.
Not a real base freak, and not a home theater person, but I do want some solid base, although I appreciate the laid back loose base of the Cornwalls, but a bit more is needed.
i will have to see if I can locate the terminals you mentioned. Any more info would be great to have. I do have Crites B3 crossover.

Cornwalls are a forward sounding speaker by design.
As such it is not so much that the bass is lacking as that the midrange is more prevalent.
The modification game is a slippery slope with extremely diminishing returns. If you have a start to finish plan and intend to keep them, which is rare, you have a solid foundation to build on.
Contrary to what purists may hold dear, EQ is your friend. Whether it’s achieved by analog tone controls, in the digital domain or by tube rolling is a matter of semantics.
If you will be undertaking other projects in the foreseeable future you could try the Crites woofers, they will find a good home eventually.
Another caveat would be to keep any “alteration” reversible should you choose to go that route.
Over the years I have tried the Crites cast frame, Eminence Kappa 15C and Klipsch K-48 woofers in my Cornwalls. Honestly, every one of them sounds better to me than the stock K-33, all things being equal. Probably because most of the alternates are slightly more efficient (louder) with the Crites sounding the lowest and the K-48 sounding tightest, once again, all things being equal.
Something I have come to realize over the years is I prefer punch in the gut bass over LFR rumble.
If you are looking for deeper lows a good subwoofer may be (will be) the simple answer.
Yes, midrange is very prominent, I feel like the base is overshadowed by mids, the woofers can make base, but it’s just too quiet. I am pro EQ and use it make adjustments to taste.
Interested in your take on replacement woofers, I feel like a woofer with a higher sensitivity would be more prominent in the mix.
I do want to go slow, but I’m fine altering the sound to suite my ears and taste, even if I move the speaker slightly away from what Klipsch intended, but I did buy Klipsch for a reason, so I want to be careful
Primaluna or Line Magnetic ?
in Talkin' Tubes
Posted
Hi, I know this is a pretty old thread but I’ll see if anyone is still around.
I'm comparing Line Magnetic v Primaluna, the one thing that PL seems to have is much more flexibility with tube selection. LM seems locked into 1 style of tube per amp. Is this correct? Also, is counterfeit LM an issue, is China HiFi a viable resource? Both sound great
