UPDATE: Following extensive Research and Development, from September 2009 our acclaimed HL1 and HL Reference loudspeakers will be made available using a more advanced and convenient two piece construction arrangement. At the time of that upgrade we will also incorporate some new internal upgrades and finish options. In the meantime we are still able to supply the existing models but stock is limited and orders for HL Reference and HL1 will be treated as bespoke commissions until the new models are officially launched.





The
Aspara HL Reference stands alone at the very summit of horn loudspeaker audio reproduction.

HLR_537

The Aspara HL Reference is a unique statement and the ultimate affirmation of serious intent. The HL Reference is both dramatic and beautiful in every aspect of its being.

By proudly declaring the pedigree and the commanding presence of the finest horn loudspeakers, the HL Reference creates a sense of anticipation and expectation for the performance which is soon to begin.

Aspara has invested all of its experience, all of its innovation, and all of its achievement in creating the Aspara HL Reference.

The most experienced and most discerning listener will immediately recognise the truly unique natural quality of the sound produced ...

Low frequency bass notes are deep, powerful, and resonant, and yet fully and individually defined. Mid and Higher frequencies are perfectly balanced and again individually defined.

The listener is transported through delicate tonal transitions, to experience world-class truly natural sound reproduction.

Aspara research has taken many years, and the Aspara team who are specialists in the field of compact horn dynamics have been active in design and innovation for over 40 years. Our design engineering team is confident you will be overwhelmed by these unique loudspeakers.

Make some time, bring your favourite music and listen to them; we know you’ll enjoy them.

The
Aspara HL1 is a no compromise solution for the serious and dedicated listener. The HL1 delivers fully defined very natural sound with balanced tonal transitions from crystal highs through deep feather soft lows. The HL1 underpins this refinement with truly prodigious power and the sensitivity for which horns have long been famous.

By the standard of horns from the past the HL1 is not a large loudspeaker, yet it delivers all of the benefits of horn loading. This achievement is the result of research undertaken over many years by the Aspara team who are specialists in the field of compact horn dynamics. In appearance the HL1 is designed to proudly showcase its horn speaker pedigree and to command your attention. It exudes confidence and has the appearance of a robust and powerful object in the room. Aspara horns incorporate advanced audio research and horn technology. They combine the effortless dynamic clarity of horn loading with a natural sound balance and very low levels of colouration. The HL1 uses a titanium compression driver to cover the whole range from 800Hz upwards. At the same time the HL1 proves beyond question that horns do not need to be colossal to deliver rich and resonant bass tones.

Physically the
HL2 is the smallest of the Aspara loudspeaker yet still retains the dynamic, involving, highly musical sound that is so familiar to owners of the larger speakers from the Aspara range. For those with a smaller room or tighter aesthetic constraints these are the ideal speaker to completely transform a home listening experience where an intimate sound experience is demanded.

The HL2 delivers clean fully separated sound from a unique cabinet designed using a quarter wave column loading technique. The quarter wave system was first used for loudspeakers by the great audio pioneer Paul Voight and we sought to pay homage to his legacy.

Inside the cabinet of the HL2 a long folded pipe is discretely terminated with a carefully designed flared vent which forms an acoustic interface with the listening room air. This design ensures that as much energy as possible is channelled away from the rear of the main driver which helps to avoid stored energy effects and the result is an amazingly clean, open sound with powerfully strident bass tones.

Inspired by our flagship bespoke HL speaker, the HL2 brings class leading performance far beyond physical size. These beautifully crafted floor standing towers incorporate a solid oak front with stainless steel detailing to enhance your living environment. These are an impressive addition to any home.

Our concept demanded that HL2 should be an attractive option for audiophiles from the new enthusiast to the most experienced and discerning listener. We have consequently set a new price performance benchmark.

Inspired by our flagship bespoke HL Reference speaker, the
HL6 brings class leading performance far beyond physical size. These beautifully crafted elegant floor standing towers incorporate a solid oak front with stainless steel detailing. Their quality and contemporary style will enhance all interiors.

HL6_C_450h


The HL6 is an unconventional speaker: it's powerful and detailed sound belies its size. It retains all of the drama of the larger Aspara horn models. The acoustic design of the HL6 allows the impressive 6 " driver to really grasp hold of the air

The cabinet of the HL6 vents into the air via an ingeniously tapered slot at its base. The end of the horn is largely closed off but is coupled to the air by the slot. The driver has a rising response at high frequencies, but this is balanced by the extra output from the horn, and a compensation network in the crossover levels the response.

The lively response of the main driver at high frequencies makes it a very fast performer and its sound joins seamlessly with that of the high frequency unit. This unique design was conceived for its low colouration and clarity. The relatively small bass horn very effectively loads the driver at low frequencies giving a rich full blooded sound which complements the incisive, yet smooth, nature of the high frequency range.
