Now look whats happened :doh:

Impulse H2 Gloss Backs :stalks: , honest my finger slipped :eek:

Sounds more like a brain tilt. :lol:

[Audio Al]

Update on these , Collected yesterday , What a lovely gent in a absolutely immaculate home , It is fantastic , The gent must be minted and have no money problems , nice position to be in , I did ask when he said he wanted to move and build a new home from the ground up how much the house would be marketed for ? The reply was £750 / £800 K

Anyway back to the H2's , Wow they are in fantastic condition , He purchased them new from Impulse so one owner , He told me he harley used them as he was more into TV and yes he had a top of the line bendy magneticly fixed LG tv with the LG sound bar , That was mind blowing , A TV you can stick on the wall and bend the screen :stalks:

Had to leave them in my van last night as what I thought would be a 1 hour trip ended up being a 6 hour trip , He was a very hospitable man and enjoyed talking about HiFi so I was in my element as well , 4 cups of coffee later I left for home , Managed to get the help of a gent from across the road to lift them into my hallway this morning as they were far to heavy for me on my lonesome :(

At some point today I now need a re arange in my ever shrinking front room :(
or I need a bigger house ( No I dont have £750K )

I am looking forward to fitting them up and experimenting with differen amp combos :eyebrows:

Also included were 2 x Granite bases and 8 spike pucks :)

Can you clear your in box please

[Haselsh1]

Oh well done. I remember hearing a demo of these years ago with valves and being seriously impressed. My room was just too small though, some things never change.

[JohnJo]

Very cool Al. Would love to hear those. Look like a big speaker, what sort of height are they, 4ft?

[walpurgis]

Geoff

Can you clear your in box please

Done. I assume it was me you were addressing Al.

[jandl100]

Impulse H2 - very nice! :thumbsup:

They like to be as close as poss to the back wall ime for the best bass response.

[Bigman80]

Where's the pictures!!!!

Come on!!!

[emoji23]

[Audio Al]

Done. I assume it was me you were addressing Al.

Yes Sir it was , PM on the way

[Audio Al]

Where's the pictures!!!!

Come on!!!

Will do when I have them in place next to the Ushers :eyebrows:

They will be as I only have a smallish room :)

[Audio Al]

John , On the plinths with the spikes installed 3ft 10" tall :)

[jandl100]

Excellent - their bass drops away very rapidly if they are a few feet into the room and they can sound quite weedy and forward.
Lovely speakers when sited well.

[Ali Tait]

Al, check out the H2 pages on the Acoustica website, there is a minor mod to do on the crossover that is well worth doing.

[Barry]

Impulse H2s are lovely speakers. In fact they are one of the very few folded horn-loaded speakers I can listen to and enjoy.

A friend of mine has a pair, tri-wired to an Audio Innovations 500 amplifier. They are located about 1/3 of the length of an L-shaped room. According to Jerry. this would appear not to be optimum, but my friend has little option. I can remember hearing that the reviewer Jimmy Hughes found turning the speakers around pointing into the corners improved the sound enormously; presumably the corner was acting as the final part of the horn.

Anyway, well done on finding yours. :) They are reasonably tall at around 4', but have a small footprint. What amplifier will you use with them?

I think that was more to do with the room he used them in.
I visited his apartment in the Barbican once, and he had a 2 level living room - the speakers were in the far corners on the lower level and the listening area was 6 or 8 feet higher at the other end of the space.
Strange setup, I think he found other speakers worked best for him facing the wall in that way as well.

Looks like the first amp I will try will be my AD Audio rebuilt AI 500 with all new valves :)

[Audio Al]

Impulse H2: Arguably the best of the lot. A derivative of the H1 which appears to have superceded it. Mostly handmade cabinet, same driver complement as H1, but a simplified bass horn folding leads to reduced cabinet volume with negligible loss of sensitivity and extension. Capable of stupendous bass quality and extension - although specified for cutoff at 40Hz, in-room measurements at home show extension flat down to 30Hz, -6dB at c.27Hz. Positioning close to the rear wall is recommended, but this speaker is remarkably unfussy about siting. Tractrix midhorn with driver open to rear and top, inverted-dome tweeter Sensitivity 95dB/W, 8ohm
Drivers: 8.5" Seas bass; 4.5" Seas mid; Focal tweeter.
Crossover ponts: 800Hz; 4Khz; 2nd order summed response.
Size: 1160mm H x 270mm W x 480mm D
Finishes: Rosewood or Oak with cloth inserts
Weight: approx 65KG / 140lb each.
Available: 1991-1996(?); list price c.£2,300
Reviews: 3 raves to pick from! (note these are all large images - 1024 pixels wide, GIF format, c. 250Kb)

Well there you go - enjoy! :)

[Audio Al]

Bass: H1, H2, Ta'us
Seas 21F-WBX: 8.5" diecast magnesium chassis, coated paper cone 21 F-WBX.pdf (944K)
Note replacements, if required, should have Qts <0.3, Fs <35hz, sensitivity of 93dB (i.e as high as possible!). Suitable drop-in replacements such as the SEAS H333 (CA21REX) are unfortunately no longer in current production, though you might find a fairly close match from Vifa for the 215mm chassis. However - the GOOD NEWS- these units can easily have the foam surround replaced, and you can do it yourself as shown on the the H1/H2/Ta'us bass driver re-foam page
.
.Midrange: H2, Ta'us, probably H1 also
Seas 11F-M: 4.5" doped paper cone, diecast magnesium chassis. 11F-M.pdf (136K) otherwise known as the H143.pdf (136K)
Replacements, if required, should have Qts around 0.7 and sensitivity of 89-90dB. Using a higher sensitivity will require padding-down with a low-value series resistor owing to high sensitivity contributed by the Tractrix horn loading. Using a driver with significantly lower sensitivity will lead to a recessed midrange - there is no scope for raising the output of the midrange crossover (i.e. no existing series resistor in the crossover to remove)
.
.
.Tweeter: H1, H2, Ta'us, H5
Focal TC90K: 1.35T magnet, kevlar inverted dome. TC90K.pdf (116K)
Well, not quite: The kevlar dome the Impulses used was a custom build using the kevlar/glassfibre dome in a 120-sized magnet and faceplate... which is 120 x 120mm, rather than the 90 x90mm of a TC90.
So - there is an easy replacement & upgrade for owners of speakers using this tweeter - substitute the Focal TC120TD5.pdf (136K) - if you can find them now that Focal has stopped supplying the aftermarket! This may require adjusting/adding an L-pad to reduce the treble level - the '120 is 2dB more sensitive than the '90K - try 1ohm resistor in series, with 22-ohm R across the 120s terminals, to begin with.

[Ali Tait]

Check out that crossover mod Al, well worth doing imo.

OK will do at a later date :)

65kg EACH? if you take these to Kegworth next year (hopefully), don't forget your "special" underpants :D They must be about the same size as your Ushers - just how big IS your house?

[Ali Tait]

That’s a typo, they’re not that heavy lol.

[Barry]

That’s a typo, they’re not that heavy lol.

They bloody well are! ;)

[Ninanina]

Gosh the H2's are so heavy... ;)

[Pigmy Pony]

I did wonder, my speakers are 4 ft tall and weigh a piffling 80lbs. 140lbs is a good way to earn a hernia, even with enlisted help.

[Ninanina]

My speakers are quite large I guess but they weigh next to nothing... so no hernia's :eyebrows:

[Audio Al]

After a massive struggle :eek: they are almost in position :eyebrows: probably need some tweeking

About to start with the amp selections see what sounds best :)

Personally I think you need to de-clutter before you can do a proper listening session, still you won’t need to go to the gym later. :lol: then you can sit down and have a rest:pat:

No. Nor can I. Looks like a normal home to me..................well, as normal as mine! :D

[Ali Tait]

They bloody well are! ;)

They bloody well aren’t. I have a pair remember. Maybe 65kg the pair, but even that’s pushing it I’d say.

A friend of mine has a pair and used to live in a third floor flat. I helped him carry the speakers up the flights of stairs and can tell you they are bloody heavy - heavier than a sack of cement, but less managable.

[Ali Tait]

Like I said it’s a bloody typo lol!

There is NO WAY these weigh 65kg each. I had help to put them in the Jeep when I bought them, but I carried them into the house myself on my shoulder. I’m a strong bloke but I’d struggle badly trying to get 65kg onto my shoulder with something the size of these speakers.

I used to carry my Mr Liang amp to bake offs and that was a struggle up two flights of stairs to my flat at the time and that weighed 50kg. No way I could have put it on my shoulder, and that was 20 or so years ago.

[struth]

possibly the quote was for both. its often done and then mistyped as each.

weight isnt the whole thing tho, its the distrobution and ability to grip and walk. a 3 by 2 slab is a very heavy thing to cart around as its difficult to grip and hold plus walk...especially if there are 100 of the buggers

Not nearly as bad as carrying a dead body, and rolling it up in a carpet makes it even worse. Never doing that again

[Macca]

32 kilo each sounds about right.

[Macca]

No. Nor can I. Looks like a normal home to me..................well, as normal as mine! :D

Yep looks like my living room too. There's even an older version of my speakers in there.

[AJSki2fly]

Clutter ? I see no clutter :scratch:

I presume you do not have a SWMBO to appease or possibly the luxury of another room for personal use, I dream of such a room but am not allowed such frivolous use of real estate:doh:.

By the way I used to have a pair and they definitely are about 32kg each, I and Sue could carry a speaker between us easily.

Enjoy listening to them.

[walpurgis]

Working as a mason pavior, I carried thousands of the things and the smaller ones. A 3ft slab weighs 170lb, I used to pick them up and rest them on my nut while carrying them up the road. I spent years laying the damn things too and granite and concrete kerb.

Sounds like a painful way to carry them. Didn't know you were a "mono ball" :D
