“Series II.” The incorporation of these changes has been concurrent with the development of our new Low B-1 1x10” model, which is being introduced as part of the “Series II” line, even though no previous 1x10”model existed. - Page 4 The Low B-1 is equipped with a Fender-type strap handle. It is a great handle in terms of preserving cabinet integrity, and serves the second function of helping avoid obstruction of the speaker’s side- mounted port.

Page 5: Introduction
I've had my eye on ultra-compact PA speakers to compete with the Elite Microns and similar, which sound good, but are somewhat lacking in bass and are quite expensive. The new Low B-1 model competes in this area quite nicely. -
Page 6: Guidelines For Use
The first is that the ability of the systems to reproduce the lowest notes doesn’t reach it’s full capability until the surrounds have been loosened up by being used. The second, and perhaps more important consequence, is that when driven to their maximum excursion, the woofers are much easier to damage when they are new, than after they’ve been broken in. -

You have doubtless already been warned. Cut these numbers in half for the Low B-1 1x10” model. We rate the Acme Low B-4 at 700 watts RMS continuous. It has been used with success with 200-1000 watt amps. -
Page 8: Placement: Low B-1
Experiment. Placement: Low B-1 At first glance, the Low B-1 looks a little strange. As was mentioned above, the speaker uses a Fender- type strap handle. The port is apparently located on the top, next to the handle. Unusual. In fact, however, the port and the handle are located on the side of the speaker. They are placed on a common surface to discourage the user from stacking another speaker (or anything else) over the port, thereby ruining the operation of the port, and placing the woofer at great risk. -

anything. Or send your speaker back to us, to insure that the job will be done right. Either the Low B-2 or B-1 systems are available with receptacles installed for use with common “Ultimate” style tripod stands. The charge for this option is $30 per cabinet. Equalization Thiele-Small modeling predicts a -6dB point of 31 Hz, below which response rolls off rapidly. -
Page 10: Covers
Covers Vinyl covers for the Low B systems are now available. We’ve contracted with a leading manufacturer of same, Tuki, to make them for us, and you can buy them directly from Acme. Standard covers are $50 for the B-2, and $54 for the B-4. Padded covers are $75 for the B-2 and $81 for the B-4. Flight Cases I am at a loss to make a recommendation. -
Page 11: Handles
The strap handle is used on the Low B-1. What is a disadvantage on the B-2, limiting stacking options, as mentioned above, is a necessity on this speaker. The location of the port, on the side of the unit, makes it important to discourage stacking or laying anything on this surface, and the strap handle helps to ensure that this will not happen. -

noticeable before. Or, your pickups might exhibit a “peakiness” that hadn’t been noticeable when used with a peakier speaker. Distortion Distortion, when introduced by any part of a sound system, will be heard from the speaker. If, for example, an amplifier has a weak tube, the effects of that weakness will be heard as distortion from the speaker. -

Before you jump to this conclusion, listen to a wide-range program source through your speaker, such as a CD. With this source, the output from the tweeter will be much more obvious than with some bass guitars, particularly older, passive models. The very high crossover point makes it nearly impossible to damage this tweeter. -
Page 14: Marketing
After listening to the Low B systems from Acme Sound, I believe you'll be as disappointed with what's available elsewhere as I was. Marketing I've tried to sell these speakers through music stores, and the response is always the same: "Great... -
