Cab Combination Question

[RickenBoogie]

Man crushing ?

Give it a rest dude.............

Until you can come back with better credentials then Bill, you just sound like a whiney spurned lover

+1 to this- doesn't make you look smart at all- quite the opposite, as well as being completely UN-necessary.

Thank you gentlemen, this is a nice polite thread. I’m not a speaker cabinet designer so I’m learning a lot here.

Does anyone know which Eminence 6.5” or 8” driver is recommended to perform best with the Eminence BassLite C2515 driver and who has the best build plans for a speaker cabinet like this?

EDIT: Preferably a perfect lightweight compact cabinet.

I've learned most of what I do know from Bill and a few others here and I'm still at a level you'd call Acoustics 101, or Speaker Design 101.

These guys freely dispense knowledge it took them years to learn and possibly decades to master. It's wise to use it to ones advantage.

Will, I agree. You know more than I - I’m a total newbie when it comes to speaker cabinet design and that’s why I’m asking what is the best - see my post above yours.

I'd start by asking why that particular woofer? It's a good driver but why that one? What will it be used with/for? Amp power? Design goals? Output needed?

Then I'd start a fresh thread on the subject as this one's been pretty well hijacked and beaten to death.

If your Ampeg cabinet wasn’t perfect would you still keep using it or would you replace it? Maybe if you post a picture of the inside of your Ampeg cabinet Bill can tell if its good or not?

My Ampeg cabs AREN'T perfect from a strict BFM-approved design standpoint. Some things I care about, some things I don't.

 

[Joe Louvar]

Ok, thanks Jimmy - me too.

Will, I’m think building a bass cabinet might be a fun project and a good learning experience so the goal is a small compact lightweight roadworthy maximum performance bass cabinet and I picked the Eminence BassLite C2515 driver because I like 15s and Bill recommends Eminence drivers and it‘s the only lightweight 15” neo Eminence bass driver. And I don’t know how to design speaker cabinets so I want to buy the best plans. I’ll dig through post and links and find the info - thanks again.

Look also at the 3015 and the 3015HO. They're both light weight Eminence speakers often found in bass cabs.

Probably the first step is to go and download winISD and start modeling different speakers. Its hard to start out in the middle of the pond unless you know what direction you're trying to swim in...Identify your end goal, tonal profile, size/weight, etc. That will inform everything else you do. But I bet you have a maximum size you want, probably know what kind of tone you want...

A lot of good bass guitar drivers, including the platforms a lot of commercial offerings are based on are listed a pro sound drivers. Basically look for what specs you desire and don't worry about whether it's labeled as a bass or pa driver. Followed by lot's of modeling and think about the tradeoffs and what ifs.

 

[will33]

If you've been a musician for most of your life but never really got into the technical side of things, one thing you might find difficult is to retrain your brain to think in terms of frequency instead of pitch, they're related but not at all the same, far from it.

Read this thread through. http://www.talkbass.com/forum/f15/bass-frequency-waterfall-plots-what-they-mean-rigs-510749/

And of course the sticky at the top of the page is full of good info and links. Check out the educational section of www.billfitzmaurice.com forums as well.

... I think the problem is that pretty much of all the audio science wizards and their disciples, want to state everything as if it is an absolute universal truth. This might be fine if the discussion is kept strictly to the theoretical physics. But as soon as you get to practical applications, a lot of that goes out the window.

... Maybe I'm strange, but I think people should find their tone using their ears and not their calculators.

It's easy but wrong to dismiss "audio science" as theoretical. It's an accumulated body of knowledge based on measurement and experience. If you want to know more about how sound waves and speakers behave, all you have to do is study.

That doesn't mean you don't also listen, it just means that you can explain what you hear in technical terms. And if you study and listen enough, you can predict many aspects of performance from specs alone. That's what engineers do; it saves a lot of time and money. And of course, listening is always the final verdict.

Sorry about that chip on your shoulder. Exageration, misrepresentation, and derogatory labels don't help your arguments. No one here is trying to diss your rig. They're just responding to the OP's questions.

There are no perfect speakers. All speaker designs are a compromise. We all pick our compromises; some knowingly, some not.

Does anyone know which Eminence 6.5" or 8" driver is recommended to perform best with the Eminence BassLite C2515 driver and who has the best build plans for a speaker cabinet like this?

EDIT: Preferably a perfect lightweight compact cabinet.

I don't know of any published plans that use a C2515 with a cone midrange. One exception (if it's an approved driver) might be the BFM Omni 15, but it's not compact. The fEARfuls are lighter & smaller, but none of them use the C2515.

+1. I would add Greenboy, Duke LeJeune, Alex Claber, and others to that list. It's quite an opportunity... I'm constantly learning new things.

 

[Joe Louvar]

Eminence has the KAPPALITE 3015 & 3015LF but no 3015HO maybe it’s discontinued - thank you for the info and I’m a GK MB115 user so I want a lightweight cabinet similar to my MB115s but better otherwise what’s the point - you know.

 

[JimmyM]

BS got the names wrong...they're the 3015 and 3015LF. There's never been a 3015HO. But in the 12" size, they have the 3015HO and 3012LF.

You're right...there's a 3012HO which is the equivalent of the 3015...too many numbers and letters!

Don't tell B&H though:

Those 3 guys are huge contributors. It's like the "thank you" speech, don't want to leave anybody out so you just say "others".

What do you guys think of the Ampeg SVT 610hlf? Would this be an upgrade from my avatar b410 neo cab? Would it give me better lows along with a smoother tone?

Better lows, no. Smoother yes, the Avatar mids are pretty scooped.

 

[MycooLeeyun]

Thanks for that input. What would you suggest in terms of cab for better lows and smoother mids? I would like to stay in the realm of 4X10's.

The one you play through that you like the best. There comes a point where there's no substitute for trying gear yourself.
