Sealed speakers

dhs0403 -- Sat, 01/21/2012 - 13:17

 Good afternoon,

My family room is 27 X 20 X 8 -- that's 4,300 cubic feet of air.
Has anyone run across sealed, full range speakers that can handle a room this large?
-- By sealed, I mean non-ported.
-- By full range, I mean down to 40Hz or so.
Or, has speaker design moved exclusively to combo systems -- high frequency stereo units combined with separate, sealed subwoofers?
Thanks in advance,

 Dunlavy SC-VI speakers have no trouble with a room this size...

I would try to find the very well regarded ATC SCM40 - but certainly you need good amplification. So much depends upon your choice of music, and the SPL that you wish to attain in the room. Are you planning on a subwoofer in the room as well?

 Thanks Steve and AV.
I've been poking around and it looks like a combo system with stand-mounted mains and a true subwoofer offers the most flexabilty and affordable pricing.

I agree with you.... the pricing is very affordable. You could also buy a used system for at least half the price.

I have used a medium room only for me. There are two sound system in my room. I always try to use the best one. You guys give me the excellent one to use as a sound system. I love my "Dunlavy SC-VI speakers" very much. Thanks for this wonderful creation. Keep it up :) Houston Custom Installers

Hi dhs,

Well to fully 'handle a room that large' I assume you mean can utilise the full bass extension capability of the room.
Since I calculate your room is capable of reasonable bass reproduction down to 20Hz a speaker with a cut-off point (-6db) of 40Hz will not fully handle or utilise the room. If you truly want to use the room to it's full ability you should be looking for a cut-off point of 25Hz or below. Assuming you want to stick with sealed speakers the bass will drop off quite gradually - 6db/octave I believe, then 6db down at 20 Hz would be the ideal (that is a cut-off point of 20 Hz), but bear in mind they will start reducing in bass output way before this, probably around your 40Hz figure. There should certainly be less than 3db drop at 40 Hz, though.

Yes you could use a subwoofer combination but I would certainly prefer 2 subwoofers rather than one for this size of room.

Audio Physic Cardeas has a sealed desing (with passive bass driver), and go rather easily down to 40 Hz. Of course these won' t blow as high pressure levels than Dunlavy SC-VI. But if you like deep, detailed sound, they should be qood. Other sealed speakers that come to mind are Magico Q3, Q5 or new S5
