I was wondering if someone could shoot me in the right direction for some high sensitivity speakers suitable for a valve amp.

I would prefer above 95db, and must be 8 ohm. Somewhere around 5k would be prefferable. I'm currently making my way through the Australian speakers sticky at the moment, and i really like the look of the Creation Audio C Horns :(

I have found a few high sensitivity speakers but they have very high impedance levels also, such as Zu.

I know they are out there, but my searching isn't returning too many results.

Ruling out DIY also.

I think some of the VAF signature speakers fit your measurement requirements BB.

The Signature line goes a bit beyond what i would like to spend ideally. Only the I33 comes within the proposed budget, and they measure at 90db unfortunately.

I should probably note that i all ready have a pair of DCX G4's.

Well there's sensitivity right there BB, but i think they dip a bit lower than 8ohms (6 and lower i think)

Yes i'm hoping the VAF's i have are suitable for the amp i am getting. (Earle Weston Topaz) I think as long as they don't drop much below 6 ohms i should be okay, but Earle know's i have these speakers so i'm sure he wouldn't have reccomended the amp otherwise.

I do like the VAF's, but i've just grown a bit tired of them. Perhaps a new amp will change all that, then again maybe my room does them no favours. I'd just like to try something that's a little different.

How about the WLM Loudspeaker line of products? The La Scala are slightly below at 93 dB, but the Divas (if your budget can stretch) have a 97 dB sensitivity!

There seems to be good things said about the Zu Audio speakers. I think they offer a trial period where you can return them if not to your liking.

Omega speakers
You can audition them in Brisbane at Audio Addiction

Zu Omen Def is around 6Ohm and rates at 98db. Might suit your needs? But I think Zu Superfly (which I have) is more suited for the valve amps. Omen might be bit more SS friendly than valve friendly, although you could drive them with a valve amp.

Klipsch speakers would be worth a look. Many speakers above 96db.

The Krix Pix is the ticket, and probably around your budget. Not high on waf and looks a bit industrial, but this is a highly engineered and refined product. The chief designer is world class. The Pix would definitely leave eye candy like C-horn or Zu chewing its sonic dust with their full range drivers. Only other one I would recommend, if you want to take your money away from aussie ingenuity, is the Gedlee, another proper audio product.

Can you can get Sonist speakers in Australia? 8 ohm & 95db sensitivity.

What type of valve amp do you have SET's ,Push Pull what tubes & power rating .


An important question, as it answers the question of whether you need an efficient speaker, or an efficient speaker with a benign impedance curve.

+1 for Omega and Hoyt-Bedford. Within your budget you could buy the HB Type 4s, which have separate powered woofers and have $2K to spare.

BTW, don't worry too much about Zus and other speakers with impedances of 10 to 12 ohms. This actually means they are an easier load for a valve map and your amp could sound more relaxed as a result.

Hi Bus Boy,

I use Rethm Saadhana single driver speakers. http://www.rethm.com/home.html#

They have few speakers in their range

Some strangeness in the specs... Class A & 35 w to start (unless B+ is quite high), says it is running ultralinear with no global feedback so likely has a fairly high output imprdance. Means you want a smooth flattish output impedance, otherwise the speakers frequency response will be multiplied by a factor of the impedance curve. With single drivers a rise at the top and the bottom coupled with a high output impedance can be beneficial as you get a boost where it is often needed. It also has to be said... that is a lot of power for a speaker this efficient.

If i was choosing a speaker within your mandate i'd be looking at Vulcan, you'd have to build or find someone to build it for you. Of course i'd use my version of the FE206

If it wasn't for the efficiency requirement, Rasmussen's Elsinores or his new flat impedance speaker would be a good candidate (the latter limited by the Visaton B200's 89ish dB efficiency.

Have you heard highly sensitive speakers Bus_Boy? My only advice would be not to rush in and possibly spending all you're budget on a set of speakers before hearing a wide range of speakers.
Plus one for the Omega and Hoyts-Bedford recommendations.
And although they are seeming to fetch premium prices these days, don't discount second hand vintage Tannoy's and Coral Beta 8 and 10s if in suitable cabinets. Tannoys and Valves = Heaven. :(

Hi Bus_boy

I run Earle's Time Machine SET into Zu Druid IVs........which have 101db sensitivity. I'm very happy with the results.

I haven't heard any of the latest Zu speakers and there are certainly other options, but I would suggest you have a close look (listen, rather!) at their current range. (Magenta HIFI is the Aussie Distributor for ZU).

cheers

Hi,
can anyone explain the role of impedance in speakers run by valve amps?. At equal sensibility, is easier to drive 8 Ohms minimum (or nominal) impedance or 4 Ohms impendance?.

Thanks.

I always thought the lower the impedance level of the speaker, the less load placed on the amp, provided the amplifier is stable at a lower impedance

Unfortunately they don't list prices for anything besides a couple of PSB speakers. It aggravates me when stores do this because quite often I waste my time ( and to an extent theirs) by looking at something that I could never afford in the first place.

I never buy from anywhere that doesn't list at least an rrp.

Are their any other suppliers?

How do Klipsch do as far as music goes? I've never really looked at them because i've always thought of them as strictly HT speakers, which i have seen a lot of amongst the HT forums.

Also is it possible to get them in a proper finish and not a veneer laminiate?

None that I am aware of.........give them a call to confirm though...........a number of the models in the Zu speaker range will be within the price parameter you set in your first post.

I will be selling my Tannoy Dimension 8s in the near future, listing on this site in the first instance. 90db with 6ohm impedance but very suitable for valve amps. More info at www.tannoy.com & I also have a couple of reviews available. Just a thought.

cheers
