Would you advocate replacing the speaker in the Citronic sub with something of a higher quality and greater excursion capabilities -Xmax?

 

But Shirley that defeats the object of buying a cheap sub?

Now who would go and do that ay ...

Cough ....  this is exactly what i was looking for as i want to avoid Rack gear and  it looks simply enough conceptually would you look at that its fallen off ebay ... 

Now ... I guess i have to decide what  at frequency im crossing .... perhaps because its running to a dedicated  bass amp rather than a sub it should shoot a little higher to 100 /120 rather than 80 ?

 

So, three months later, did this work for you?

From John @Chienmortbb recent review of his system ( 2 x Wharfdale Typhon 8's) he invested in a second Citronic Casa 10 sub to achieve the performance he was seeking. Wishing to use just one sub, it seemed an idea to upgrade the speaker in a light , well made cab and panel amp. On my radar would be the next step up from the Citronic Casa 10 to a Alto TX12S to match the Alto TS408s. But would I achieve similar performce from a £100 speaker upgrade?

That was the basis of seeking John and Phil's opinions.

Question to @Phil Starr and @Chienmortbb.

Would you advocate replacing the speaker in the Citronic sub with something of a higher quality and greater excursion capabilities -Xmax?  Maybe Faital Pro, Celestion or B&C ?

This is very much John's project and I haven't yet had a chance to listen to his system. 

 

Our thought was that at the price he paid the plate amp with a built in crossover was worth the price of the package. We had discussed just about every possibility including my developing a cab and John the amp from scratch and this was cheaper than the parts for the amp. When it turned up it was surprisingly well put together and sounded OK with the original Wharfedales.

 

I did run models to look at using better quality 10's including Fane, Celestion, Beyma and Faital. Most of these gave no increase in output, mainly because they are only available in 8ohms. I did manage to find TS parameters for the fitted drive units as they were being sold as spares at the time. The 120db maximum output checks out as genuine. This compares with RCF/Yamaha and the like who all routinely quote only peak output which is 6db higher than the maximum continuous output they actually develop. The last conversation we had about this was to try the speakers and if they are short of output for John's needs to try some of the drive units I have as replacements. My feeling is that it's not something I would set out to do as a plan and there isn't a speaker for sale at sub £200 that would give you the extra 6db that a second sub would guarantee.
