Default Pearl Acoustics

I'm in the process of building 10.3 Pesils. Cabinets are done and I'm just waiting for the drivers to come in the mail. I was browsing the net and come across these The Sibelius. Is this what I can expect my Pensil's to sound like? The shure look like Pensils. What shocked me most is the 4995 euro price tag.

Having talked with Pearl, my understanding is that these are not Pensils.

AFAIK, they're a tapped ML conical horn, aka a Weems pipe, aka 'ML TQWT' in current parlance (i.e. the opposite of what GM & I call a TQWT ). They won't sound exactly like pensils since a tapered pipe will have a somewhat different gain BW.

I don't know any design details of the cabinets in question, but in fairness, if you're making bespoke speakers out of solid French oak in the UK on a low volume basis, the price is somewhat more understandable. If you're flogging hundreds of speakers a year prices can drop as you can hack the margins. If you're only selling, say, 1 pair a month, then margins need to be higher for the business to be viable. Depends too on facilities they have, who makes them, where they source materials etc. Speaking generally, the latter in particular often mounts up for smaller companies, since it's rarely practical for them to order large quantities of materials in, either for restricted finances, storage etc. reasons, so they quite often end up paying retail for the components that go into the speakers. They might be able to claim VAT back, although I'm not up on tax law. You get the idea though.

gee, the Valentini looks very familiar

indeed:

The Valentini is known in many circles around the world as the Frugel-Horn Mk3. It was originally designed as a project by an extremely talented and dedicated team back in 2011. They were looking to design an enclosure that could faithfully reproduce the widest audio spectrum with the smallest feasible single drive unit in order to ensure purity and clarity. Their wonderful design has been described as a ‘timeless classic’ and Pearl Acoustics are proud to be given permission to manufacture their design under license


Yes, low production, artisanal bespoke work with slow grown French Oak is a far cry from BB plywood in terms of both cost of material, and the skill & time to fabricate and assemble.

Best of luck to any of the folks entering into this field - with competent design and craftsmanship, it's not particularly difficult to get excellent results with any of Mark's drivers - in the current economic environment, the survival of any ambitious business model is another story. .

Aye, although it's not exactly FH3, it's a revision of it specifically for the A7 done for Pearl. Haven't heard from them for a long time, so presumably they haven't sold anything. Not surprising given the economic conditions, as you say, and the absence of any marketing that I've seen.

Looking at the way the economy is and the price of a good pair of speakers I am thankful for you guys and the diyAudio community for all the great ideas and support.

Has anyone seen the video of the speakers playing the drum solo? Is this type of excursion of the speaker okay? Bastiaan Jonniaux - Sibelius Loudspeakers - YouTube

ebiz - Mark would be the best to comment once he gets a chance to (temporarily?) decompress from his traveling, but knowing from first hand experience how delicate the Alpair metal cones can be when physically mishandled ( i.e. non music related damage), it does look a bit scary when you monitor the excursions that closely

to be honest, I was likely getting close to the same degree of excursion with my MAOP7s this past weekend, and should probably be much more cautious with this rare species

I am always bemused with YouTube posts of loudspeakers - as if most dinky little desktop sets or even worse, laptop speakers, can begin to portray what the units being demo-ed can achieve. I've heard the Alpair 10s that are used in the Sibelius in a couple of different enclosures, and as much as I quite like the little FF85WKs / Topping TP30 combo at my desk, even with a sturdy down-hill tail wind, it can't come close to what the Alairs can do. sorry, just a pet peeve

A true craftsman knows how to work wood and also how to work with wood, the number one rule is wood moves seasonally but only across the grain in any noticeable amount, so a box with 6 solid wood panels or 12 glue joints has 4 cross grain glue joints that are continuously under stress and will eventually fail
