Purchased a DB Technologies 400W active sub a few days ago.

Specs are:

12in sub
400w RMS
127 SPL Max.
Bandpass enclosure
Dimensions 520x360x500mm. Weight: 19 kg


I was planning to buy another, but am unsure as to whether using 2, with a total of 800W would perform equally if not better than 1 x Mackie SWA1501.

Mackie Specs:

15in sub
500W RMS
128SPL Max.
Bass reflex enclosure?
Dimensions: 59.7 x 43.6 x 60.3cm. Weight: 40kg

Portability and compact design is high on my list of desirables, but I wouldn't want to compomise this for sound quality/power.

Although possible, I think it highly unlikely that someone has actually tested/compared both setups, so I'm equally interested in any opinions that people might have.

if portability and compactness are high on your list, then two subs seems excessive.

i think you should go with ONE, although i still dnt think that one mackie will compare to the power of two subs

I also posted the same question on the Mackie forum and was told that due to acoustic mutual coupling, using 2 subs close together will increase the overal SPL by +6db. This would bring the 2 smaller subs up to about 133db SPL. General consensus seems to be so far that using 2 of the smaller DB technologies subs will be more effective soundwise than a single Mackie SWA1501.
