I have (perhaps) an unusual take on the reproduction of recorded music, due probably to having always been mightily impressed with the visceral impact of club installs and the bass slam and depth they could generate. Home hifi in the 70's if you were poor was.....IMO....well..... pretty poor and playing the same records heard at the clubs was pitiful in comparison. Fast forward to about 10 years ago when I was still trying to recreate that sort of sound with a "proper" hifi system. I have hsd countless pairs of speakers and amps etc etc. I ended up getting a pair of very large good quality PA speakers (15" bass units) which IMO sounded pretty good, but were lacking in some areas. So I thought I would add another pair of speakers to use in tandem. This combination sounded pretty good. I am sure that most will throw up their hands in horror and say "that simply doesn't work" for a whole host of reasons. But it did for me. I moved the PA speakers on after a few years of on/off use and had other speakers in and out, but the thing that I continued to try was more than one pair in tandem, sometimes it worked, sometimes not. Anyone tried this? About 3 years ago I was able to buy some Lampizators P17's at a bargain price and as these had 15" bass units I thought these might be the ones for me. After trying very hard with them for nearly 2 years I was not really happy with their presentation. I was then gifted a prototype pair of EAR Primary Drive OB's. I had to get these to work properly, but I felt that these were more "me" than the Lampy's. However, they did a lot well, but not all. So...what did I do.......of course....paired then with another pair of speakers. I have some vids of the Lampy's (playing alone  ) and hope to add one here. I will take a vid of my current rig, which in all probability will not sound too different, but as you will all know "I can hear the difference" |

Does not sound as if 2 pairs would work, but I wonder if you have invented a new tweak.....and of course the ears are the best guide

Even on my desktop I get the sense of a open detailed sound
I love it when people find their own way to the sound they want

Wonderful. I love different solutions for different needs. Have you ever, in your search, tried some JBL pro speakers?

I have heard large JBL's at shows. Do you mean the small ones?

No, I was wondering about the medium sized studio models like 4412 or 4312.

I was thinking that. Parallel loads or separate power amps?

Interesting Lampizator s mate.
I remember you struggling with them before, but now I see them again I realise that they are a totally different design and as such pursue produce a totally different ocoustic .
Each baffle seems to have a board sticking out of it between the baffle and the side wall, what is this board? Each baffle seems to have a black kind of peak on the top what is this? Lastly is that another driver I see above each 15"driver?
I like your unauthodox thinking by pairing different speakers together to get the sound that you want sometimes it is trains of thought like this can really produce the sound signature that you need and tailored to your room.

The Lampy's have a an extra unit sitting above the bass box run with a separate amplifier. They are OB GLL Imagio's which use Inductive Coupling Technology (a sort of dual concentric design - I think) I got them from an audio jumble and knew they would be put to use one day. There are no other speakers being used in that vid (although another pair can be seen) I probably didn't make it clear that I am currently using 2 pairs and will post a vid of this The "side panels" were a bit of an experiment with soundstaging. They are just leaning against the main baffles. The "black peaks" (good marketing tag that) are some 90 degree shaped old grilles that hang over the back of the mid-range units to soak up some of the rear output. I have been told that I am a bit mad (as in bonkers) and what you see may well confirm those opinions. The proof of the pudding is of course in the eating and most who have heard my, perhaps, unusual take on things have said they were impressed |

It's been a while since I've seen how your approach is evolving and I think it's great that you're continuing to enjoy your music against perceived hifi wisdom. Great work, keep it up!!

Puffin, your not bonkers at all, it's people who spend a few grad on speakers,plonk them down a when they don't sound right sellthem on and never really get to where they want to get to, which leads to years of chasing your tail.
Thinking as you do can really get you to where you want to be. I found the weakness of the Lampizator P17 (conventional ones) was the tweeter. I changed this for an oval vintage Isophon that has transformed the sound, much easier on the ear.
I see , like mine, your listening room is quite narrow, I recently hung some thick curtains behind the speakers and screwed some carpet on the side walls , which produced stupidly good results. I'll find my thread for you.
BTW I'm so impressed with the Lampizator sound done properly that I am about to upgrade my Lampizator P17s to the P24s. My P17s will be up for sale soon.

So true. A speaker purchase, no matter what the cost, requires time and a little effort to optimise them for your setup. |

I had thought about doing something like that with a large rug my son "donated" to me (basically I think he just wanted me to get rid of it). Took up a lot of room in the garage and so I stuck it outside where it's open to the elements. Better get it in and dry it off! |

I have been very lucky speaker wise and never had to spend silly money. I was made redundant in 2012 and became a p/t postman. At one address I saw a pair of speakers sitting in the rain outside a house. I enquired if I could have them, and was told that the person who could say yes or no was out. 24 hours later with constant rain I went to collect them. Really heavy, mid-range unit foams were gone and they were a bit battered. Got them home, re-foamed and smartened them up and they are really good for nothing.    |
