The loudspeakers are, by far, the most important component in any stereo system. If you are building a component stereo system from scratch, you should plan to spend about half of your entire budget on the loudspeakers.
Speakers, after all, are where the sound comes from. Choosing the right loudspeakers for a home stereo music system is not easy. A simple physical inspection, without even turning the component on, can give a reasonable idea of how well it is made.
However, this is less true of loudspeakers, whose most crucial elements, the drivers, are hidden inside the enclosure. All you can see, even with the grill cloth removed, is the front of the cones and what is behind the cones is what matters most.
Loudspeakers are the least accurate of our components. They are the typical stereo system's biggest source of distortion, coloration, un-natural resonances and other problems. Unlike the electronic components, they interact with the listening room in which they are used, as well as the listener's ears.
The 2 Best Tarantula Enclosures in 2020 (Buyer’s Guide & Reviews)
No two people hear sounds, especially music, identically and we play different kinds of music at different listening levels. All of this complicates speaker selection. Loudspeakers with high fidelity pretensions are usually provided with at least some specifications, but what and how much is revealed varies with the manufacturer. Usually, the more detailed the specifications, the better. It tends to indicate that the manufacturer has less to hide. Common loudspeaker specifications include the type and number of drivers, nominal system impedance usually 4, 6, 8 or 16 ohmssystem frequency response, efficiency, power handling, crossover points, physical dimensions and weight.
The impedance of a loudspeaker system varies with the frequency it is reproducing. The impedance specified is usually an "average low"; the system should not go much below that specified. Eight ohm systems are the most common and almost all home audio amplifiers can handle eight ohm speakers.
Four ohm speakers, especially if they dip below three ohms at some point, can be a problem, as the amplifier may begin to see them as a short; this can send an amp up in smoke. Today, these are usually professional speaker systems. However, most amplifiers that can handle eight ohm speakers can also handle 16 ohm speakers. The speaker system's frequency response is important, particularly at the low end. The most typically quoted frequency range for perfect human hearing is 20Hz to 20, Hz.
However, our hearing response is such that there is not much practical difference between a tweeter that extends to 17, Hz and one that goes all the way to 20, Hz or above. On the other hand, most people will definitely notice the difference between a speaker system that can reach 50 Hz and one that can reach 40 Hz or, even better, 30 Hz. To be meaningful, frequency response specifications must be accompanied by an indication of the allowable variation in loudness, expressed in decibels db.
The smaller the specified variation the better. In other words, decibels add up fast!Drawing on our extensive range of deck enclosures designs, Altec builds beautiful home extensions to suit any house.

There are so many different kinds of tarantulas with hundreds of different personalities and physical traits that will bring you tons of entertainment. There are several things to consider when building an enclosure for your new pet tarantula. This guide will help you to understand the needs of your individual tarantula and let you know exactly what they need in order to thrive.
If you watch video content about tarantulas or read several different tarantula blogs, you may note that people keep their tarantulas in a wide variety of different enclosures. While there are definitely some enclosures that are inappropriate for tarantulas, most are more than acceptable. Tarantulas are wild animals with millions of years of evolution behind them.Altec Lansing 604 Hollywood + Utopia enclosure (cello test)
During this time, their bodies have become fine-tuned for surviving and thriving in the environments that they live in. As stated previously, tarantulas have special environmental needs that have developed over millions of years. Tarantulas can be classified into two groups when it comes to their enclosure setup, and those are arboreal and terrestrial tarantulas. Alternately, terrestrial tarantulas rarely climb off of the ground, opting instead to create burrows that they stay in most of the time.
Because of these differences, you need to know whether your tarantula is an arboreal or terrestrial species in order to create the perfect tarantula enclosure. On top of the general structure of their enclosure, they also have needs that are specific to each individual species. For instance, each species is native to one or several regions and thus is used to a certain climate. Therefore, humidity and temperature are both factors that need to be considered and properly maintained.
While all tarantula species are different, there is quite a bit of overlap between species in terms of their environmental needs. As long as terrestrial tarantulas are able to burrow and arboreal tarantulas can climb and create websmost of their needs are being met.
So, as long as the enclosure has all of the features that a tarantula needs, you can make it look as realistic or as sterile as you want. Realistic-looking enclosures are easily a crowd favorite, though.
Substrate will cover the bottom of the enclosure and serve quite a few features. Namely, this substrate will retain moisture within the enclosure and give terrestrial tarantulas a place to burrow. Many owners opt to dig out a burrow for their tarantula before-hand and reinforce it to help it last longer. In addition to substrate, rocks and fake plants help to make the enclosure look much more realistic, give the tarantula more places to hide, and provide anchor points for webbing. A water dish and a sizable tarantula hide are also essential for every tarantula species.
Not all tarantula enclosures are created equal. There are simply better tarantula enclosures out there that are higher-quality, more spacious, and better designed for tarantulas. With all of the different enclosures available on the market today, it may be stressful trying to find the perfect enclosure for your tarantula. Fortunately, there are some enclosures available that perfectly meet the needs of tarantulas.
Below are our two picks for the best tarantula enclosures — one for terrestrial species and the other for arboreal species. Fortunately, this Exo Terra enclosure is the perfect size for most terrestrials. It boasts square inches of floor space with room for several inches of substrate to be placed underneath door level. It also features a waterproof base, raised base to help with heat distribution, and even a decorative textured backdrop. The dual doors are well-constructed and allow for great accessibility within the enclosure for feeding and cleaning.
There is also a full screen top that allows for excellent lighting and ventilation and is built to be very secure. Overall, this enclosure is built to contain a wide variety of terrestrial tarantulas in style.By bracurrieFebruary 5, in 2-Channel Home Audio. Here in Nashville Altec A7s were all the rage in studios when they were introduced. I just met an older musician that did a lot of TV and recording from the early 50s here.
He has a set of A7s he wants to sell. All I know is that the horn is in an enclosure that has fabric in front to pretty it up. I haven't yet been able to find photos of that model. Using the horn with a LaScala bass bin or lower K-horn cabinet would probably be a good combination. It is difficult to give advice on this since the A7 cabinet could have many different parts inside. The woofer is usually a various versions or and the tweeter horn is usually a or but not always.
As Mark mentioned, over the years many have come up with alternative cabinets all large that typically decrease the port area extending the bass response lower. They sound okay in their stock form, but in order to shine they would need to be taken on as a project. Do a search on "Onken speaker cabinet". Some folks, but not all, really like that kind of sound. Just found a trail to photos myself. I also found this. Something like this. I'm someone that fell completely in love with Altec A7's about 8 or 9 years ago.
I bought a pair that had seen better days at a local pawn shop. So, I had the bass drivers re-coned and the high frequency diaphragms replaced by Great Plains Audio.
