Ok, there was a thread in the non DIY subwoofer forum debating if the ed a7s-450 and the cs 18.2 were the best deals on the market in terms of performance per dollar.


Someone had brought up doing a mal-x 18" as an alternative, so i was curious how it would compare up to the A7s-450, and also the a7s-650 DIY kit, as its about the same ballpark price range.


I pulled the driver files from this link:
http://www.hometheatershack.com/foru...pro-files.html


Purple line is Mal-x 18" with 4.5ft^3 box and 2400w (EP2500 bridged into 4 ohms)

Green line is eD 190v2 with 4.5ft^3 box and 1300w (pulled internal volume from eD site for box size, matched the mal-x even though you want more like 5+ cubic ft for a malx 18")

Yellow line is Dual 13av2's in a sealed 3.6ft^3 box (also per eDs stats) with 1300 watts. Basically thought id throw an A7s-650 kit in there as you can get the kit for $1125 shipped and its in the ballpark of these other subs


@20hz:

Mal-x 18" - 111db @ 1m

190v2 18" - 107db @ 1m

Dual 13av2 13" - 106db @1m

mjg commented on the mal-x vs. the comparable sealed e.d. iirc, he preferred the mal-x.


also, there have been some problems with reported vs. measured specs from e.d.


the cs18.x looks good to me based on specs and design principles.


there are lots of options.

Well, i just have very limited experience with the modelling software so i was primarily wanting to make sure i actually modelled those correctly.


I admit the 190v2 in particular looks to be better performer in software than it is in real life. What would be the point of the A7s-650 if the a7s-450 basically outperforms it in every way. Anywhoo.
