That is what my first thought was. Do you think that setup would work to give me a flavour of what going active can do? Maybe do: Passive pre - DCX - 6 Channel Amp - drivers I also have a friend locally who has a umik microphone and knows how to use REW software so I’m sure he would step in and help.

Another very kind offer, Keith. I’m not sure I could accommodate so many boxes at the moment, I was initially looking at picking up a cheap 6 channel amp, maybe something like this Rotel: https://www.ebay.co.uk/itm/254718681186 I will definitely drop you a line RE the DCX. It seems you’re only an hour from me so I can collect, if thats acceptable.

Thanks all. The Behringer unit has really piqued my interest, I think I may have to accept Keiths kind offer and have a play first. I Will definitely need to do some research in to the right kind of amps to use.

I think the La Scala may benefit greatly from the level of control that this setup seems to allow. Because the crossovers use autotransformers there is some small control over the levels (db) but its more rule of thumb than anything else. Thank you for the loan offer, thats very kind. I may take you up on that After reading the replies above, I now have a better understand of the chain of connections i.e. source - crossover - amplification - driver/speaker. This makes sense with the explanation that the source signal is split before being amplified and then fed to the driver. With that in mind, for the Klipsch, am I right in thinking I would need 3 matching stereo amps or 6 matching mono amps, is that correct? If so, what kind of amplification are you using? I have a couple of amps hanging around but not matching. Amp / driver matching is mentioned above, do some of you use the same amp for each driver, or do you pick different amps to match the driver i.e. higher wattage amps for large woofers etc. and are we talking branded “hifi” amps or more commercial type amps?

I don’t get it...... help!? I keep seeing these words and reading threads where people have “active” speakers or have “gone” active. Then there are those that have used “DSP” or Mini DSP or those that have EQ’d room modes etc etc..... Do you have to buy active speakers?....... how do you turn passive speakers in to active speakers?....... is it always going to be an improvement when changing passive to active? So many questions......... Would it be worthwhile setting up a sticky thread that explains these things in layman's terms to help the uninitiated?

I think that may be a pro mixing desk that has been covered over.....?

Huuum.... good question. I spent a lot of time reading and planning the project before I started and there was quite a bit of waiting around for parts etc, but if you discount the prep-time, it probably took around 25 hours for the actual build over a 2 month period. The biggest issue was getting hold of the mid-range horns, which I wound up waiting 6 months for due to stock and shipping issues from Klipsch in the US, as well as the covid problem. Drivers and pretty much all the other parts and components are easilly come by on eBay, but the only other alternative for the mid-range is a tractrix horn, which I didn't want. It is worth noting that I don't really have any woodworking skills per-se and was kind of learning along the way. If I was to do it again there are a few changes I may make but only minor things. Total cost for the build is somewhere around the £900 mark, which I believe represents great value for money.

There are no kits available for them but I do have various plans, if you would like a copy drop me a PM. These were built from scratch using all original Klipsch drivers and horns, the crossovers were fairly easy to make but the mid-range horn was a pain to get hold of. Here is a link to the project thread: I must admit, I don't think I could bring myself to pay £10k + for these or any speakers, but having had loads of fun making them and learnt a lot along the way, I certainly think they represent great value for money for the build and parts cost.

Horns don't need to look like something off a space ship...... and can be fairly easy to build! I made these myself but they can be bought off the shelf for for £12k https://www.henleyaudio.co.uk/products/la-scala-al5

SOLD. But I’m not allowed to say who to....... 😜

Holly Cole - Temptation (200g Quiex)

Thought I’d give this a little bump! There have been many takers for these in the last 2 years, they’re still available to anyone with an interest.

Mid-week bump and small price drop. Now looking for £600 for the deck and arm or £675 with the cartridge.

Great thread and in my case, very timely, as I have just been looking in to a mod on my speakers to increase the low end and did think that a sub may be easier. However, it seems that to integrate a sub properly will take additional equipment, such as the DSP kit mentioned by the OP One that has caught my attention is a table tuba, which will apparently match well with horn speakers, but they are rather large..... has anyone heard or used one? https://billfitzmaurice.info/TT.html

Thanks for this, its really helpful! The HF is run through an Autoformer on the crossover, which allows some tweaking I believe. I’ll have to do a little more research. 👍🏻
