I am interested in building the Pi 4 using the best components possible and have a few questions.

1st a bit of background - I have built the La Scala's as bass for the Oris system but have grown dissatisfied with the full range Lowther sound - I just can't get on with the anomalies that the Lowther produces and I have been dissapointed with the LaScala bass bins with K33 drivers - they are best described as 'lumpy' and not extended.

I would like to know how low the Pi4's go? Are they suitable for smallish British rooms 12ftx15ft? And.... are they musical?

Also I already have some 2226h's - so what would the cost of the rest of the drivers and crossover etc be to send over the pond?

Best regards

Stefan

Wayne - advise needed before I embark I guess - if you have a design and crossover schematic that would be hepfull - many thanks.

If you have two good corners, go with the Professional Series seven π loudspeakers. I use them with SET and ultra-linear PP amps, and just love them. They've been my favorites for a long time, since the 1970's. And they've had incremental enhancements over the years too, so they're the best they can be.

If you can't commit to using corners, you might go with the Professional Series four π bass bin and the midhorn, tweeter and crossover from the seven π.

The standard Pro four π is very nice too, being a DI matched two-way design.

In each case, the woofer is tuned slightly overdamped, so bass rolloff is slow and smooth. This makes a nice conjugate for room gain, and won't let bass become boomy even in "live" rooms with solid plaster walls like in some European flats.

I like the sound of the Pi4 bass base with the Pi7 mid and top. I do have corners and can build the Pi7 corners but at this time I have a deluge of speaker carcassess! So my thinking is to re-use the LaScala bass bins (that I lovingly put together - weep!) to accomodate the 2226h - it appears to be about the right size and I can jig saw out some of the front bow of the dog box and add a font panel cut out for the driver. The rest of the dog box together with the reverse horn will probaby aid in attenuating the rear wave (aka B&W Nautius - reverse snail - or at minimum act as a good brace).

Many thanks

At any rate, I'm not comfortable that a basshorn folded like the LaScala should be used up past the bass range. When I use a basshorn that is folded this way, I tend to also use a midbass driver to cover the span between basshorn and midrange. The only thing I don't care about Klipschorns is they don't have a folding pattern that lends itself to propogation of midrange frequencies and I think they push them too far. I wouldn't suggest using one in this manner.

I have tried the DJK mod with skirt an ports - they are Ok - just don't like the bass of the LaScala - its just lumpy and not that good on upper bass - plus the K33 cone seems too soft and the bass is kinda bouncy.

The JBL pointing out front should do a mans jobs of it.

Thanks for the plans etc. I am in the process of moving house at the mo so will digest the schemes and get back to you.

Also I've sent you a picture of my previous Oris style speaker - its all hand and home made.

Thanks - more than tuppence worth of advise - I think you are right.

Just these things don't seem to sell well round these parts. Its such a shame as I built them so bloody well - I mean they are better than any LaScala bass bin - birch ply - absolutlety precise joints - horizontal braces around the dog box - I mean I spent 2 weeks on each cab - weep!

I may keep them as... tables?

I like the idea of eventually building the 7 horns for a numer of reasons 1) horns rule 2) they are Waynes favs and that counts for lots 3) I lurve horn bass (when its right) ).....
