An idea that deserves a wider audience.

I always put it down to them having reasonable quality drivers including a OK sized bass driver and not having a stooopid ports.

Devialet Phantoms are a prime example of this. 16 to 25 khz claimed frequency response and incapable of recreating the sound of a bass drum or bass guitar or a bass in any way that resembles those instruments -relatively speaking.

On their website they say ' With performance 10 to 1000 times superior to anything previously measured, sound will never be the same.' and 'It took over 80 specialists in aerodynamics, automobile, acoustics and mechanics to perfect a system capable of sustaining these extreme physical conditions. 10 years of research and development and 25 million euros went into engineering the best sound in the world.'

Yes that marketing spiel smells of pure bullshit. Devialet is one of the brands i would never entertain. Too high tech for my liking (too much to go wrong), reeks of bullshit and if the pfm fanboys like it then that is a definite no no for me.

I have never heard any and don't suppose i ever will (knowingly ). How much are they ?

Massive solid Walnut cabs and no crossovers.
If only they weren't ported.

They are not cheap.

And then there's my EV Sentry III wide baffle ported speakers with 15" drivers that I'd rate as "average" in the bass department. So even going large may not overcome the sonic drawbacks of ports.

The ported speakers with the best bass that I've come across are probably Steve 57's DIY'd speakers, but then they are semi ported, semi open baffle. And they do have decent quality 18" drivers.

Would anyone care to nominate any ported speakers that they think does bass well?


BTW, apart from sealed and ported and open baffle cabinets, there's also the Hartley Boffle.

This looks like an interesting idea and one worth trying some day...

These have a 12” wideband that is run open without a crossover, cone is doped to improve high frequency response in a similar fashion to what Richard did. They use a compression tweeter run from a single cap for a simple first order crossover above this.There is also a resistor in series to pad the tweeter down to the 12” sensitivity, and an Lpad to set tweeter levels to taste/room.Lows are taken care of with an 18” Goldwood driver, run from a 3000w Behringer Inuke with DSP, crossover set at 200hz 2nd order. These are capable of some serious bass should you require it, and easily tweaked to taste. Surprising these give more and better bass than my previous OB’s with twin 15” a side.
