More Bass

Go right to the source.  Call Legacy — I imagine they have good customer support and could save you a boatload of time and stress. 

$640. Or double to 4x10” for $860. I took 2 of the 2-10s so I could place them in different spots.

Walk around the room.  Does bass get better, worse or doesn't matter.  A continuous tone is helpful.  I  have 20 and 30 hz only.  Also, it will take a few days, many people play new speakers continuously for a few days.

@mrskeptic - lol

I'd suspect inferior fuses in the amps and if you've already changed those, you should *invest* in some Marigo Tuning Dots and a Shakti Stone. 

@jeffreyw - that's great advice thank you I will do that tomorrow!

I would contact CODA and speak with Doug regarding your bass issues. He will set you straight. If necessary, the CODA can be easily biased at the factory to V3 to get more power. Keep us posted; this is an interesting issue!

@jeffreyw  - very interesting. Coda is configured as a V1 as I was looking for as much class A as possible

@jeffseight - Gee, I wasn't looking for any subs really, the Swarm is four!

I will give it more time and try to figure out the room some how!

@navyachts 

What variant is your CODA #8 biased to (V1, V2, or V3)? The rated amp output nearly doubles per variant. I don't think you should be wanting for bass with the nearly full-range capability of the speaker. The CODA's are pretty ballsy, also. 

I had a similar problem with the bass output of my Kef Reference 1 Metas powered by a Luxman 590AXII. Many suggested it was my room. I then bought a pair of McIntosh MC611s, and my bass output easily tripled! I could easily fool someone into thinking I was running a sub now. 

Unless your room is the size of a movie theater, this one is tough to figure out.

Even my car stereo speakers sounded better after a few weeks of using them. Like your situation, the bass was rather weak at first. Same goes for my house speakers after I had new surrounds installed. Give 'em a chance.

Okay the trial period will save your bacon!

If you keep the Legacy speakers you may need the

Wavelet to tune the room. +$7k AHHH!!

The Coda gear is excellent.

Personally I would have suggested you try a "Swarm" approach

to enhance the bass with any speakers you buy. Legacy is a pricey

option.

Why not go to Chicago in April and hear a lot of brands

at Axpona? 

@jeffseight - still have time on the trail period, but I’d just like to try and make these work, so more burn-in and I have to figure out some kind of inexpensive room treatments. I blew the motherload on a major remodel and this stereo. I’m suppose to retire in May, sure hope they can keep me on for a few more...

@tuberist - will do

@wturkey - switches sound better up, bi-amped sounds expensive! Do you toe your Sigs in at all?

@jc4659 - phase OK, thanks

Legacy Signature 3 owner here. Does your speakers have the switches on the backside to turn off and on the rear firing tweeters? Maybe play with those switches a bit and see if it helps. Read the manual first. They may be in an undesirable position. Also mine are biamped. 

Your speakers need to break in. You probably need some room treatment and I would ask dealer advice on how to get a max set up.

@ddd1 - my apologies, yes two 10" woofer (not 7")

@soix - yes, sealed box design, other speakers I have had have been rear ported, so adjusting to them makes sense. Last speakers were Kef R 11s.

@russ69 - amplification is a Coda #8 for power and a Coda CB pre-amp

Yes, the room is not great and I’m working on it. I will continue to break them in.

Is the trial period over?

You probably already did this but make sure the speakers are not wired out of phase.  After that it's likely your room / speaker positioning. 

What are you using for power?

The crossover components as well as drivers themselves need at least 200hrs of signal running thru them to open up and stabilize. Way too early for a judgement call. 

The Signatures I believe are a sealed-box design, so maybe if you’re used to hearing ported speakers the bass is just different so you may need to give some time for your ears to adjust and for the speakers time to settle in more.  From what I saw it looks like they have dual 10” woofers and go down to 22Hz (-2dBj, which is damn near full-range.  Maybe try pushing the speakers a little closer to the back wall to possibly add some extra room reinforcement?  BTW, what amp are you using and what speakers did you have before?  Just some thoughts FWIW, and best of luck in figuring this out. 

Likely your room or the way they’re set up, but without a pic, who knows?  Knowing what amplifier you are using might help too.

Also, what’s with your 7" woofer reference? I thought they had 7" midwoofers + 10" subwoofers.

Are you sure the issue is the speakers and not the room? Have you had satisfactory bass in this room previously?

@soix - they have a few hours on them but Legacy themselves say they don't need break-in (I have the email).

Sorry to hear that. I have a pair of Atalante 3 monitors with 7" mid woofers and they practically sound as bass laden as my JBL 4319 monitors with 12" woofers. They give up very, very little and even have a stronger mid range presence as well. I'm inclined to think it may be your room and that some break in is needed.

All the best,
Nonoise

Are the speakers broken in or are they new?
