On my Parasound pre I have them cut off at this freq. The 15" subs I now have take over from there and I think I will let the new subs do the same. The La Scala bass bin is no longer horn loaded just over 100 Hz and rolls off sharply below. My mains are high passed @ 200 Hz just to give you a heads up. 18 minutes ago, joop said: As you say the THT can be build in a few different versions, but that's not quite clear to me, from what I find on the Bill Fitzmaurice's site. Do you have more info on this? There is 3 versions, snail shell, end firing and front firing all are the same horn just folded differently. Cabinet width can be built from 15" wide to 36" wide, the wider the better. The other dimensions remain the same but width is variable.

Wim M Posted June 16, 2017 Author Share Posted June 16, 2017 Just as I came home with all the material (birch plywood, drivers, ...) I found out Klispch announced a Heritage Sub. So I started to build anyway, I don't know what to think about the new Klipsch sub, it looks like a beefed up R-115SW with DSP on board. I really would not know if this one is able to keep up with the large Heritage models like Khorns and LS's. Now I am really hoping I won't be disappointed in these Tuba's.

derrickdj1 Posted June 16, 2017 Share Posted June 16, 2017 From looking at the size of the box, it should have no problems mated with the LaScala and most of the Heritage line. 1 Quote Link to comment Share on other sites More sharing options...

If you are using La Scalas out of boundary effect--as in outside, elevated above ground, this is correct. However, if you place them in a small room--like those in homes...virtually all of them...boundary gain (i.e., horn loading) will lower that cutoff point. If you place the La Scala along a wall/floor or in a corner, the gain is much greater. This is horn gain almost an octave below the La Scala bass bin's 1/4 wavelength point.

What makes the bass bin loaded, and what causes it to be "no longer horn loaded?" I thought horn loading had to do with providing a horn with enough energy to make it produce notes. For instance a trumpet doesn't make a true note unless there is enough air going through it. Quote Link to comment Share on other sites More sharing options...

Chris is right, floors, walls and possibly the ceiling (depending on height) can also be a loading boundary but its never going to take the place of a proper subwoofer. 1 Quote Link to comment Share on other sites More sharing options...

I've read with interest you journey towards the La Scala II's. I'm a (very happy) RF7-II owner myself, pairing it with 2* SVS PBUltra13 to get that bottom end ;-) The La Scala II's do have a rather heavy price-tag associated with them, so I can image they sound great!

Hey, another Klipsch enthousiast from Belgium! Where are you located? The subwoofers are finished, but haven't heard them yet. I'm still waiting on the amp and X-over. I ordered a QSC DCA 3022 which puts out over 1kW/ch @ 4 Ohm. The X-over will be a Xilica XP 3060. I'm also waiting on a few other MDF panels to make two other cabinets which have to help integrate these big boxes into our living room, you know, there's always the WAF Not always easy to get all the materials you need during the holiday season... Hope to get them running by the end of september. The LSII's play in another league than the RF 7II's, they are a complete different story. The LSII is a very revealing speaker, they let you hear literally everything, with great ease, undistorted, also the weak links in your audio chain. The R-115's were the first to be sold, next I think will be the Parasound P5 pre amp. I'm looking for some tube pre, maybe a Mcintosh C2600 (hopefully within a few years). So if you add up all this, the La Scala II's come indeed with a heavy price tag. Quote Link to comment Share on other sites More sharing options...

avguytx Posted August 17, 2017 Share Posted August 17, 2017 So how much is that Heritage sub going to retail for? Quote Link to comment Share on other sites More sharing options...
wstrickland1 Posted August 17, 2017 Share Posted August 17, 2017 Someone mentioned a Palladium sub with LS2's. I agree a horn loaded sub is ideal but I can say that the P312w does a pretty good job with those speakers. I haven't used the calibration mic yet, just set the low pass to around 70 and let it rip. I am just running a single sub. 1 Quote Link to comment Share on other sites More sharing options...
