drivers for the cubo 12

hey im a total newb to building speaker im looking for the hceapest suitable driver for this cab and was wondering about the eminence delta and delta lf would either of these work or even better are there any cheaper options also if someone wouldnt mind explaining how to find a suitable driver then id be quite happy to find one myself. im also looking to make some midtops to go with these but havnt decided on anything any recomened designs ??????? any info much apreaciated.

All I can say at this point is to look for what has a high EBP. If you need a sub, then just go over the specs and get what looks like it has the best low curve.

That's my guess, but I'm pretty green anyhow! smiley14

well if u can get your hands on these they will work fine..

smiley1 hello,
I'm considering building a cubo 12
as a cheap newb, I'd like to ask you how do you think this driver (with a qts higher than the recommended) would perform in a cubo 12
?
250w /8 Ohms
Resonant Frequency (fs) : 47Hz
DC Resistance (Re) : 5.0
Coil Inductance (Le) : 0.64mH
Mechanical Q (Qms) : 6.00
Electromagnetic Q (Qes) : 0.50
Total Q (Qts) : 0.46 (when between 0,2 and 0,37 is recommended)Compliance Equivalent Volume (Vas) : 120.1 ltr/4.2 cu. ft.
Peak Diaphragm Displacement Volume (Vd) : 237cc
Mechanical Compliance of Suspension (Cms) : 0.29mm/N
BL Product (BL) : 10.8 T-M
Diaphragm Mass inc. Airload (Mms) : 40 grams
Efficiency Bandwidth Product (EBP) : 94
Maximum Linear Excursion (Xmax) : 4.4mm
Surface Area of Cone (Sd) : 538.9cm2
Maximum Mechanical Limit (Xlim) : 11mm

a bit more guidance from Master Cubo :

"For best performance the Qts should be less then 0.3 preferably.
fs 45 - 52 Hz,
Vas below 80 Ltr, Xmax above 5.5 mm."
