Lowther Speakers USA

1. Because Lowther speakers are fullrange (30 hz to 22,000 hz). Combining separate woofers, midranges, and tweeters--by using crossovers--is unnecessary.

2. Detail, accuracy, and realism are unmatched because the sound comes from a single voicecoil.

3. Clarity, speed, and low distortion are unrivaled because Lowther speakers have the lightest cones, the strongest magnets, and the most rigid frames.

4. Imaging and soundstage are unsurpassed because the sound comes from a single point in space.

5. Lowther speakers are also the world's most efficient speakers. Minimum efficiency in any enclosure: 102 dB/1 watt/1 meter.

Lowthers come in two frame sizes--8 inch and 6 inch.

Lowthers use three different magnet materials--ceramic (ferrite), alnico, and neodymium.

Lowthers come in two different designs--standard and 'EX'.

First, decide whether you want a bass reflex design or a bass horn design. We have free plans for 10 of our own bass reflex designs, 7 different factory bass reflex designs, and 10 factory bass horn designs.

If you want a bass horn design, we recommend the Lowther DX3. It is an exceptionally detailed speaker. This enables it to 'compete' with the cabinet resonances and delayed sound that comes from a bass horn cabinet.

If you want a bass reflex design, figure out the acoustics of your listening room to make the best choice:

--For a 'live' or 'hard' room, we recommend the PM6A or DX2.

--For a 'medium' room, we recommend the DX2.

--For a 'soft' room, we recommend the PM2C or DX3.

Silver voicecoils are available for $50 each, but not recommended. They have the effect of lowering the detail of each respective driver. This is probably due to the heavier weight of silver. So, a DX3 Silver, for example, would sound like a DX2. So--rather than spending the extra money--we recommend just buying the next lower driver in the range.

Phase equalizers (rather than the standard 'bullet' phase plugs) are only suitable in front loaded bass horn enclosures.

More than 99.9% of all speakers ever made are bass reflex designs. That's because they give the most clear, detailed, accurate, and realistic musical reproduction. We offer ten different models of bass reflex cabinets of our own design. With your purchase of a pair of speakers, you will receive a free set of our cabinet plans, a parts list (and where to get the parts), and a list of setup tips. In addition to our own designs, we can offer seven different factory bass reflex plans.

All of our enclosures can be constructed with 3/4 inch Baltic Birch or marine plywood, MDF, or industrial grade particle board.

A properly designed speaker cabinet should only do two things.....hold the speaker in position and make bass. Generally speaking, each increase in cabinet size adds about 10% more bass and dynamics to the presentation. The mid and high frequencies of each speaker are very similar. But with more bass on the bottom, the overall tonal balance of each speaker is different. Each cabinet is tuned for the best balance given the size limitations. In the smaller cabinets, this is done by taking bass from the extreme bottom octaves and moving it upwards. So, the larger cabinets have greater extension and can produce higher sound pressure levels, but the smaller cabinets still have a balanced presentation.

Among our 2.8 enclosures, the Series I is a bit softer and warmer than the 2.8 MkII models. The 2.8 MkII is a bit more detailed and efficient. And we offer two different cabinet tunings (or 'porting') for each of these cabinets. The Twin Port models have slightly lower bass extension. The Big Port models have more mid bass.

For bass reflex cabinets, you have a choice of three different lines of Lowther speakers. Each uses a different magnet material-- A Series (alnico), C Series (ceramic/ferrite), and DX Series (neodymium). But magnets don't have a 'sound'. The voicecoil only reacts to a magnetic field. It is the overall design of the magnet (size, shape, and material) and voicecoil (size, depth, and design) that gives the overall sound.

With bass reflex designs, the cabinet is inert and contributes nothing but bass to the presentation. So, you can pick the driver with the right level of detail for the acoustics of your listening room, quality of your recordings, and listening tastes. The driver doesn't have to 'compete' with the cabinet as it does in a bass horn enclosure. Moreover, in a bass horn cabinet, you should--ideally--purchase the most expensive Lowther you can afford, so the driver can 'shout' over the colorations of the cabinet. But this is not necessary in a bass reflex cabinet. Here are our recommendations:

Bass horn enclosures are traditional cabinets with origins going back 60 years or more. They offer a soft, warm, and smooth sound and are popular for classical music. We offer plans for ten different factory designs and can advise you on which one is best for your room and your listening tastes. If you're going to expend all the effort to build bass horn cabinets, choose a design from the Lowther experts.....the factory.
