the box TA 18

Purchased currently three weeks.

This is my first sub.
Purchased to complete my bass guitar amp especially for benefits outside.

So far I had only played on small sound systems HK Lucas, Martin + 2x400W Harrison VMOS without sub, thebox CL112 (really small) Bose L1 and bass amps Trace Elliot 4x12, Hartke 4x10, 1x15 craft, Peavey 1x15, 2x12 Hartke.

I use a head ashdown little giant 350 + speaker 15 "+ 2 tweeters bullet, I was looking for a good quality sound (with accompanying songs and jazz fretless bass Cort B4FL.) The 15" amp should be supplemented by a sub 18 "to be consistent.

Characteristics (not very rigorously presented ...)
----------------
This is a 1x18 active sub "type band-pass.
The SPL is given to 131dB, I have not measured but fellow musicians who were in the audience (outdoor concert) liked.
BP announced 35 to 250Hz, without elaborating.
500W power advertised, unspecified either, but it's really the powerful use.
Weight 45kg. Puree.
Dimensions 70 x 58 x 53cm.
Seen by a transformer vent ring indicating an analog amp, probably MOS-FET power saw serious.

Appreciation for the use
----------------------
After a break of 3 concerts in 1 room + outside with a stone wall behind the TA18 proved more than enough for projecting at least 10m, without help from a wall, or on the back or on the sides or front cover. Bandwidth gradually decreasing soil at low E (49-41 Hz), but I had fallen low by security because I play without limiter. Bass between 2-channel Soundcraft EPM6 a left exit for ashdown head 15 "and right output for the TA18 (XLR only) to equalize separately.

Features
--------------
To:
+ High sound pressure felt in outside at least 10 meters
+ Bass quality, correct linearity "walking bass" (test fatal to poorly designed boxes)
+ No ear fatigue after 2 hours, confirming linearity (for a band-pass)
+ XLR connectors (without locking, but hey ...)
+ Low-pass filter with adjustable cutoff frequency 80 ... 250Hz, extremely useful
Phase inversion switch +
+ Solid cabinet

Cons:
- 45 kg. Transport with the devil and strap, two people to the stairs.
- Tendency to tilt during transport, poorly balanced with handles.
- Congestion
- Doc in English and German, and overly concise.

Do not know:
- XLR outputs for satellites do not filtered air (doc dumb), but I have not checked. At least they exist.
- No input jack, but it is normal for the sound equipment.

Quality / Price
----------------------
Remarkable. For amateur equipment is strong, powerful, clean, seemingly well built. Reliability: appointments in one year.
There are better and lighter for the same power, but not at all the same price.
The audience really enjoyed the sound quality (outdoor, 100).
I would say almost professional equipment first prize (provided that you stick a fake label "Nexo" Just kidding In addition I do not like too Nexo.).

A remake or not?
----------------
For this particular purpose, the TA18 is a remarkable reinforcement, very reasonably priced, clean and powerful sound. I would have liked a dry sound a little more (to pay with 12 "or 15" front). I have not tested the bass drum above.

Well, it's heavy, but at this price and given the performance, I do not see how I could regret it.

Bought used a year ago, I needed a sub to complement a pair of SX200 Elecro-Voice (12 "), to play the piano bar on a large outdoor terrace for the summer season.
The machine is awesome, very heavy, probably too big for my use, no corners or wheels, so provide a devil to move and two people to lift it into a vehicle, but it rocks against a max it should take it easy, low wear away, I use also room at a very low level and in the end it proves indispensable.
Even outside, I pushed just so it sends the person to whom I had purchased the mobile disco and told me he kept one of the two, and he put the amp TA 18, a third of its power, so it's powerful, I want to believe.
The frequency setting is complete, good surprise, I put the high cut 100 Hz instead of the usual 90, to leave a little low high because I have only 12 "satellites.
That's a big sub, heavy, bulky, crude formwork but with a damn good filter, and the phenomenal power for a very affordable price.
I guess there are better its fine or whatever, but at what price, what kind of sub amplified costing an arm quickly.
In any case, I am more than satisfied, with little financial means.
Lacking experience on other subs I force myself to remain moderate in my appreciation and I put him 8/10, but for the price maybe he deserves even more?

Very good product quality / price ratio, I used this active subwoofer with two speakers "TA12" brand "The Box" she amplified the same. Indoors it is possible to make sound systems allstyles more than two hundred people.
I've never try it out but it is better to take two "TA18" for such events as power disperses faster, better dissemination is recommended.
To stay in the range, the best configuration is to use two TA18 TA12 and two of her treat her well and put the right height to TA12.
The only drawback is that this box is quite heavy (50kg) so plan a skate board if there are long distances to go before the scene.
Otherwise it is transported by a person pulling.
