Best SOUNDING 18 inch. in a 150 litre enclousure.

Best sounding?
B&C speakers from top down to 18PS76, with some LXPXXX RCFs in between...

Got two as new in the for sale section

While I cannot discart your note about noise, I had not encountered ANY problems with B&C speakers (many models from 12 to 18") when mounted in enclosure and used for flat tuning or -3db drop in lower bass for lower tuning and longer bass extension. Only hi-fi freaks tuning this speakers below 30Hz, while not getting really high SPL to mask these noises effectively, can have serious problems with this. I can´t blame them, but the speaker is not built with this in mind.
RCF is definitely better with this with most speakers.

But for other things, I see no serious flaw.
It sounds awesome. Measured TS parameters are usually 4-10% worse compared to specs, but for the price these are still very good and very usable. I have some fast measurements of some B&C speakers, and these are quite good, almost up to specs. Also other people measuring this have the same data (posted online). So I´m not sure what you´ve got, but mine is good, and I´m happy to come back and buy more B&C. Especially compared to RCF, now in different price range.


P.S.: I don´t sell any speakers.

Wow that is pretty sick! I´ve never encountered anything like this with B&C. Hope I stay on the lucky side. People around me measured BL around 23,2 and Qts around 0,4 on the 18TBX100. That´s about okay for higher volume bassreflex and great bass extension for moderate power. And it indeed sounded good for the purpose. My fast measurements of some 12"-18" B&C speakers also suggest good values. So I feel very sorry for you, and I wonder what´s happening.
Here´s measurement of one seller: http://www.prodance.cz/data/attachments/mereni_BC_18TBX100.pdf

I have my 18SW115 for some low level signal measurements, and it looks very cool. BL is again lower than marketed, but still very respectable number of 28.
Here is some Klippel measurement:

The RCF driver looks like poor sibling here.
I can´t figure it out, where is the problem. It´s weird that we experience so different results. But it happened, so I see reason for your attitude.

And you´re right. I´m even happier for their drivers. Way better sounding in my opinion (compared to competition), and some graphs show it too.

Don´t you have it backwards?
BL of 28 is good value anyway, but while for 8Ohms it´s about good, for 4Ohm it is AWESOME, and it indicates very powerful motor. See B&C IPAL series of speakers. These are very low impedance, and kinda low-ish BL factor, but these speakers are WAY stronger than what BL number would suggest, because this number doesn´t say much without context. More telling and usable force factor formula is "BL^2/RE".
