Greetings All,
As I now seem to be making a few tentative footsteps into the heretical arena of Home Theatre, re an 'add on' to my Naim system, I will need to start considering the addition of a sub woofer.
It seems to be an area fraught with some difficulties re finding a product that will interact in a suitable manner with the SBL's.
Personally, I find the bass of the SBL's quite superb, and don't want to 'mess' with it. However I'd like to consider a sub for LFE if I could find one that would extend the range downwards in the bass of the SBL's without affecting PRat etc, as even on movies, those qualities have a most positive influence upon the enjoyment of the movie experience, albeit not quite as 'critcal' as music.
As a starting point, I would be interested in the REL Q400, or the Strata 111, as they are both acoustic suspension/sealed box bass loaded units, which I would prefer over a ported design. Are they both suitable for HT, and some music use, or is it that the Q400 is mainly for HT, and the Strata for music? Could they sucessfully do both?
The other brand that interests me, although I've never heard them, would be the higher end M&K designs with their 'push/pull' speaker designs, said to give very fast transient response, and slam, which interests me.
Still, I've really only briefly heard a Strata 111, and liked it, but need to investigate what's available and likely to suit the SBL's, and hence would greatly appreciate the input from others who may well have tried some of these subs, or had experience with other high performance/Naim suitable devices.
As always, thanking you for your input,
Cheers,
Peace to All,
John..

Hi All,
16Hz pipe organ at 105Db - now that's what I call HiFi..
I'm using 72/Hi-Cap/180/SBL's. (Plus CDI for music) For HT, I've added a Sony ES series digital processor, and matching mulitmode power amp. I'm running front preouts from the processor to the 72, and the Sony power amp drives a smallish pair of bookshelf speakers for the rear. (American EPI's - acoustic supsension design, best placed back to the wall like SBL's, and good down to 50hz or so)
I was intending to run the sub from the output from the processor.
Being a newbie to HT, as far as I'm aware, with all 4 speakers set to large, the LFE will be redirected to those, in the absence of a sub. However, I've refrained from doing so (ie set LFE to off) re concerns about possible damaging the SBL's with high cone excursions re dinosaur footstomps etc. Of course the EPI's would be incapable of reproducing any LFE.
However, I may be best off resetting the rears to small, so the bass for those channels can be redirected to the fronts, provided there's little chance of overloading them. Prior to this, I was simply using the DVD players analogue outputs to the 72, running in straight stereo, and as I understand it, the downmix process ignores the LFE when using the DVD player in that manner.
The new set up is a lot better, but I've a bit of a learning curve ahead of me to get the best out of it, and a sub is on the agenda, as I am a bit circumspect re putting LFE through the SBL's.
Hope this explains better what I'm hoping to achieve.
Cheers,
John.

What is your current setup? Are you gonna use a Surroud processor / AV2 / Surroud receiver? Or just feed the sub from the sub-out of your DVD?
Please let us know!
