b&c 18tbx100 cabinet design needed

i am not 100% sure but i seem to remember people used to rate the 18tbx100 in a EV T18

If that is any use to you

Produce a killer sound. Take no prisoners.

If its a standalone cab, id 100% go with the Tham 18 personally.

You can't polish a turd!

I'm looking into a Cubo SuB or this is my own design

I'm not sure if WinISD models bandpass boxes correctly (or is even comparable to BassBoxPro), but that looks like about the same output you'd get from a vented box of about 15% smaller size. Have you checked the options for Vented in that software yet?

Below is WinISD's take on your box in blue and the same driver in a vented box of 170l tuned to 41.5Hz in yellow. The 3 graphs are SPL, Power consumed and Excursion respectively.

Edit: If you do go with your BP6, I'd recheck the airspeed for the front vents - they are outputting most of the sound from the cabinet, so I'd be surprised if 2 x 9.4 cm vents are going to be big enough - probably better to think in terms of matching he size of the rear port.

David.

Oh my , you're right!

I just wanted to recreate a sound like LS1200 , not that hard slamming bass (techno) but more warm and deep bass (not chest thumping but trousers shaking bass). So I just go with the B&C SUB18 design or what is your advise ?

Thx in advance & regards,

Tim

Hi,

Vented certainly works as a sort of default loading type to give reasonably flat, extended response, so should sound quite neutral when done right. Trade off is it's usually not going to be the very loudest option.

Bandpass should give some gain when compared with that, so I'm not sure if BB6Pro and WinISD are actually modelling it correctly - might be worth investing a bit of time looking at other modelling options - I believe Hornresp can be made to do BP's for example.

The MS18 also suggested should definitely be louder than a vented box, being horn loaded, but I have no experience using that style of box so I'm not sure what the subjective tone would be like.

Not sure if you've tried already but as there's already a pro box that you like the sound of, it might be better to see if you can source those second hand rather than building an approximation based on possibly inaccurate models? I know Nexo aren't the cheapest and plenty people hang on to them so maybe that's just not practical/affordable for you right now though.

HTH,

David.

Local company is selling them , but it's like €600/Box without TAX , so there aren't cheap indeed. But I think i'm gonna with the THAM 18 , lots of wood working and its gonna be a challenge for me . I've build the THAM 12 with b&c (12nld76) and they sound good , but doesn't reach to far (+-2 meters max).

Thx man!
