La Scalas

[Taz]

I'll try to keep it simple.

Are LaScala more efficient in the bass when setting on a

Cement slab floor,

Carpeted cement slab floor

On risers which raise an inch or 4 off the cement slab floor?

As usual general harassment welcomed with replies (as long as you leave my mother out of it).

Corner placement will improve the bass but the three variables you mention will affect room acoustics overall but not bass efficiency IMO. I did like the 6 inch risers I built for mine. It got the mid and tweeters up to ear level and seemed to improve imaging.

I have LaScalas on cement floor, and carpeted cement floor, and there doesn't seem to be any difference, but my room is huge at 50' wide by 60' deep by 24' ceilings. I'm with tomprof that tilting the LS back makes a difference in not only imaging, but bass response. The bass horn is also pointing slightly up. I have a 2X4 under the fronts only which is slight enough to still place things on the speakers, and get that benefit.

Yes.

Imaging was the biggest improvement by tilting 'em up.

The best bass improvement I got was from adding another subwoofer and doing the "crawl."

Two Anarchy tapped horn subs are my next upgrde.

This is off topic, but....

I've often wondered how much better the bass would be with a second bass bin under a LaScala. The mid and tweet would be close to ear level, and there would be a +3-6db gain on the bass.

No reason to talk about mom, she's good

I have only heard them on the cement or on grass outside, the speaker were on grass not me, if I remember correctly. I always thought they had pretty good bass, but not so much at lower volumes and you can't always have it loud enough to get good bass. but a well integrated tight sub could help with that.

Not for a living room but for something like you have with your shop I know what would put a smile on your face and you could build it. Take your LaScalas disconnect the wires for the bass drivers changing nothing else, and slip a couple of mwm cabinets under there and connect to them FOR the bottom half of your LaScala

It's just using a different folded horn for the bass, could even be the exact driver, so the crossover even has no change, just much more bass.

It's like a LaScala with a big butt, I thought of your shop because I use them outside and they can fill a big area easily.

how does core efficiency change by placement differences?

[minermark]

Iv got my Scalas on 4" soft casters, rolling around the shop floor (Concrete), iv noticed NO difference in base, im just thinking about doubling up the entire system this year for the h-ll of it.

You can get a cancellation notch whenever there is a quarter wavelength distance between a bass driver and a boundary. That's about 9 inches for 400 Hz. If the riser is no higher than that there should be no problems. Carpet or bare floor won't make a difference in the bass region but carpet will help with reflections (floor bounce) from the mid and tweeter.
