Small subs to match open baffles?

wixy · 31st January 2010, 02:36 AM

Not along ago I built a pair of the MJK open baffles (FE108ez and Alpha 15A), which sound good but I am a bit let down by the bass performance.

I'm just wondering if it would be a good idea to build a pair of small subs to go with the open baffles?

What small subwoofer drivers would integrate well? (my room is only small at around 3.5m x 3.5m).

Would this dynafone 10" driver which caught my interest be a possibility?

$183 with shipping is totally ridiculous for a 8 ohm sub with 7 mm Xmax. There are much cheaper and better options.

Hi there: Sugest Tang Band WT-1427B 10-inch ($79) or W8Q-1071F 8x12-inch ($80) or W8-740P 8-inch ($66) from Parts Express in the US. All have Xmax above 9.5mm.

Are you kidding me? There are Exodus and CSS drivers available in Oz already with more output than that toy.

Add another 15a.

What amplifier are you using? I ask this because Martin mentioned something about
listening to this speaker with a solid state amp and liking the bass. Then switching to
a tube amp and noticing a lot less bass.

Thanks for the advice guys, I didn't reply sooner as I didn't realise there were replies.

I'll give the dynafone a miss and consider the suggested options.

Woody, i'm using a Rotel solid state amp with 60w per channel. The bass is not bad, it's just that I'd prefer more I guess. Although the more I listen to them, the more I am starting to be impressed by their bass performance.

The bass is weak because there is no 6db/oct. dipole EQ. The Alpha 15 could do much better.

I reckon having this filter (1 op-amp) between your pre and amp would be a better value and the polar response is kept as dipole. I had used the Alphas before and they definitely have great bass (no shortage of bass reported on EP CS2!)

Building the filter using breadboard may cost you about $15.
