Speakers with deep/powerful bass

What is your budget  these cheaper speakers have bass but it’s far from bein tuneful and accurate , bloated is a good way to describe vs even a goodsubwoofer like a Svs 400; Rel anythjng over $1500 in a sub will be more accurate 

in a speakerover $10 k for quality drivers , please remember only 25% on average goesinto thespeaker this includes all packaging ,the rest R&D overhead and markup..

If we start with the retail price of a product and work backwards from the dealer and from the distributor, then typically- not always the selling price from the manufacturer to the distributor is half the retail price.  This is typical for luxury items.  The manufacturer's selling price is based on manufacturing costs plus overhead, administrative costs and profit.  (Marketing affects the price too but only in the positive direction, ie. if a company cannot make money producing a product then they won't.)  The manufacturer's selling price is typically a 300% markup added to the material and labor costs of the product plus a markup for profit.  This 300% covers all costs of doing business- R&D, Healthcare, 401k contributions, taxes, building leasing, utilities, etc.  Labor is typically 8%-13% of the cost of the product making material about 90% the cost of a product.  Luxury items that are low volume and mostly hand made can skew the labor costs higher to maybe 15% of the cost of the product.  

So let's say, for the sake of argument, that the cost of all materials for this pair of speakers adds up to $4,000.  These are some premium grade components and very expensive cabinetry.  We will also assume all assembly is done in house and not farmed out to a low cost country.  Focusing on one speaker we have $2000 in material costs.  This premium speaker contains some high dollar composite material that costs $10/lb.  This speaker weighs 200 lbs and let's assume that half the weight is the cabinet.  That's $1000 for the cabinet material.  (That's $1000 of our total of $2000 material costs).  So the other $1000 covers the drivers, crossovers and hardware.  This is definitely a premium speaker.  Labor costs are about one hour to cut the panels for the cabinet at $150/hr machining time.  Then assembly of the cabinet and finishing takes 4 hours because this is a handmade labor intensive finishing process typical for a premium luxury product.  Assembly of the components into the speaker takes one hour and testing takes about 0.2 hours.  Say being a premium speaker it is subject to a listening test, then we add 0.8 hours.  6 hours labor total for assembly and test costs about $30/hour (unburdened) so total labor is $180+$150 or $330.  Manufacturing costs of our high end speaker, material and labor is $2330.  Add in 300% for overhead, admin, etc costs and this speaker now is at $6990.  Add 10% profit and the manufacturer needs to sell this speaker to a distributor for $7689.  Final cost to the end user ends up being $15,378 for one speaker or $30,756 for a pair.  The irony is that this business considers moving the manufacturing to a low cost country to save on labor.  That's right- the $330 that it costs to machine, assemble and test the speaker.  They potentially could save $100 minus shipping costs.  The other way to cut costs is to reduce overhead so that the multiplier is not 300%.  That means either outsourcing or moving the engineering, administrative functions to a low cost country.  But in the end these measures have limited impact on costs.  This is my opinion:  Outsourcing engineering and administrative functions lowers product quality in terms of both design and reliability, customer service degrades as well  leading to a loss of reputation and market share.  In other words, it is a downward spiral.  

And that sums up the challenge of my entire engineering career trying to keep costs down and keep jobs in the US.

@carlsbad  says who exactly? Lol that is one old trope. Debbie Downer, your wet blanket is ready 

@gregdude Sounds like I hit a nerve.  Sorry about that,  good luck.

Experienced that at the movie Earthquake.
