Hello. I am searching for a good 10" woofer for a 3 way project. I currently have Usher 8948A + 9950-20 but i would like faster and punchier bass. The 8948 doesn't really reproduce the lower frequencies that good, it's just powerfull bass-wise for it's size, but it doesn't have the neccesary speed to reproduce music relatively accurate. I also heard ScanSpeak Revelator 18W and that's also on the soft side bass wise, it has quite a lot but no speed and accuracy in the low frequencies. I haven't heard the Ciare but from the specs (FS 30, QTS 0,35 , cms 0,52mm/N ) it looks like something between hifi and pro drivers a little. It goes low enough from my experience with the Ushers, but it promises punchy and fast bass. My other option was Audax PR240Z0 but that is more expensive and the Ciare seems quite a bit better. What are your opinions?

Are you absolutely certain you have done everything needed
for the Usher to perform well? TS parameters are promising.

A friend of mine with experience did the project for me. From what i have learned from him, it's Usher's and ScanSpeak's bass signature. It goes low for a 7" mid-bas but it doesn't have the speed, kick and detail in the lower frequencies as i would like. The ScanSpeak speakers have been built by anothe DIY-er in my country and still the bass signature is the same, warm, low, but it's kinda lasy, boomy. The drivers have been measured correctly and the filters were adjusted with the help af a microfone, nu just by simulations. I also tested them in 4 different locations so i could hear them in different acusics and with a few amplifiers and good DAC-s. The midrange and highs are really good, but i want faster, punchier bass, not just low and fluffy, lazy. That's why i want 3 way speakers with 10" woofers. From what i've seen on troels's site and my friend recommanded, a QTS between 0,32 and 0,38 is needed for a BR enclosure, a CMS lower then the Ushers( the rubber surrounding is really soft so they can have a low FS, they are poorly mecanical dampened, i think this is part of the problema because in Usher Audio built by themselfes you can read in the reviews that it sais you need a powerfull and good amp to drive them properly). Anyway, my friend unfortunately hasn't worked with a lot of hifi drivers, but heard a few, he mostly likes some of the proffesional ones for monitoring and studios for their more accurate and uncoloured sound. He also likes the midrange of the Ushers and ScanSpeaks but not their bass, he told me they were going to be lazy sounding in that department before we started the project. The T/S parameters are very close to what Usher states.
So, how about the Ciare?

Actually, the overall damping is defined by the Qts, which is a
product of Qms and Qes, so the driver is damped very well
and certainly has the right TS parameters for a ported box.
I still believe something went wrong with the project. Is there
a way you show us the project data including XO filter?
Concerning statement " one needs a powerfull amp to drive them
properly" is not saying that these are hard to drive, rather the old
truth, for driving properly any speakers, one would need a good
quality piece of equipment in any case. At least, that would be IMO.
Ciare appears to be of solid built with favorable TS parameters for
ported box, typical hifi speakers of medium price range. How would
they sound depends.
As i mentioned, i know very little about DIY, i may have said something stupid about the T/S. Anyway, the speakers are really well built, they have been auditioned by some friends who have heard very expensive sistems and speakers and are experienced audiophiles and they said that the speakers are really good for 7" drivers, it's a matter of taste. One said they have the sound signature of Sonus Faber Cremona, that's just how they sound. I like a sound signature that is a little more joyfull, lively, exciting. I didn't say they sound bad, just that i want more in the bass department, quality wise. So the speakers have been auditioned by quite a few people, and all said they sound great, but i wand big speakers that really have a punchy and fast bass. I also heard Usher 8945A in another project and they also sound very similar if not the same as my 8948A in the bass department. It's not even the point of the thread, but thank you for the help. I am interested in hearing some opinions about the Ciare or what 10" driver do you think will be up for the task. I know that some say that for a fast bass you shoud build sealed enclosure, but i don't want to saccrifice the extension so bad or build a very large enclosure. So BR enclosure with 10" woofer.
