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.

This is based on a message I sent to @JohnDaBass.

 

My first outing at Open Mic night . I used a single Sub with two tops for an open mic on thr 12th Feb. 
 

I took one sub, it sounded good. I hade the sub set to 125Hz and in hindsight should have used  80Hz. 
 

 I also had the HPF on 90 Hz on the Wharfedale’s and should have let the sub’s crossover take care of that. Over all the sound was good  I did not want it Bass heavy but in the event had to boost a bit around 100-120Hz. In
 

My band currently have no gigs until May at the moment so next outing is March Open Mic  on March 12th. 
 

I will probably try feeding the sub(s) from an aux feed then. It was frustrating not to be able to just go and turn the sub up at times. Using Aux Fed subs means I can use the PEQ on each output to suite both subs and tops, rather than relying on what different manufacturers choose for crossover/ LPF/HPF frequencies. 

 

In a band setting, I would not be out front so the Open mic is great for learning what the gear can do. 
 

I did put the Kala UBass through it and it sounded nice, although I don’t expect bass will go though it that much at Open Mic. One of the performers had a Fender Acoustasonic guitar and it sounded great through the system. 
 

In reality I did. It really need the Sub, there was plenty of bass coming out of the Typhon 8 AXFs. However there may well be a couple of keyboards coming next month so will take one or both. 
 

 

On Thursday, I could have made do with just the Typhon 8s. There quoted response +/- 3dB is 65Hz to 20 KHz, enough to be used as a bass cab in all but Dub.
