This is just to give an idea. You can use a multiple ->where() and eager loading ->with() for your query. Take a look with this query below:

$products = Product::where('price', '>=', $min_price) // you get the max and min price 
        ->where('id', '<=', $max_price)->select('id')
        ->with([
            "brand" => function ($query) {
                $query->whereIn('id', $brand_ids); // [1, 2, 3,...]
            },
            "specifications" => function ($query) {
                $query->where('some_column', '=', 'possible-value'); // single condition
            },
            "specifications.subspecifications" => function ($query) {
                $query->where([
                    'some_column' => 'possible-value',
                    'another_column' => 'possible-value'
                ]); // you can also pass arrays of condition
            }
        ])->get(); // This will return the products with the price set by the user
                   // Since we're just using ->with(), this will also return those products
                   // that doesn't match the other criteria specifications) so we 
                   // still need to filter it.

Finally, you can filter the products which matches the specifications, - the product with an empty specifications means this product does not match the criteria, therefore we'll have to remove it from the collection.

$filtered =  $products->filter(function ($product, $key) {
    return count($product->brand) > 0 && count($product->specifications) > 0;
    // add your other boolean conditions here
});

dd($filtered->toArray()); // your filtered products to return
