Small sub

Good point for your sub you need to consider room volume H x W x D = cu ft. This is important you need a big enought sub to pressureise the room or it will be point less, actually you shouldn't determine the sub size the room should. Also you need a big enought cone to get the low notes 21 hrtz is usally good watch the specs on small subs they just never sound deep to me ot the ones that get that low have big distortion at volume. Last there is a guy you may want to google craig's subs he seems to of dedicated his life to nothing but testing subs.

Hey Y'all,

MJ Acoustic. Small, somewhat powerful, depending on which one you purchase, and they go very low. I'm running two Reference 150 Mk IIs. The power is rated at 150 watts and they go down to 13 Hz at -3db. Dimensions are 11.8"W X 14"H X 11.8D. They are made by the original crew that made Rel in the UK before Rel moved their manufacturing to China. They are very easy to set up. You can find more info through the industry directory here on the 'Gon.........John

Ive owned a Totem Thunder three times in the last 5-6 years: highly recommended!

PMC TLE1 has dual 6 1/2 inch drivers and a flat frequency response down to 22Hz. It's not a square box but a slim rectangular box that may fit your criteria of being small. It pumps out quality bass with the internal Bryston amps rated at 150W and totally kills my Dali SWA-12 with a 12" driver. Big drivers don't necessarily guarantee better quality bass or the ability to go lower down the frequency ladder.
